From 42889fa24afd9586a523ece99bd8d5e92c08ff0f Mon Sep 17 00:00:00 2001 From: douglasacost Date: Wed, 29 Apr 2026 14:28:11 -0400 Subject: [PATCH 01/36] docs(collections): add user collections technical specification Specifies an operator-triggered NFT collection factory: users pay in fiat off-chain, a trusted backend deploys a fully-isolated EIP-1167 clone (ERC-721 or ERC-1155) on the user's behalf. Factory is UUPS-upgradeable; clones are immutable per release. Both creator and operator hold MINTER_ROLE on each clone; per-collection metadata (baseURI/uri + contractURI) and royalties are owner-mutable until locked one-way. On-chain externalId map prevents duplicate creations from the off-chain ledger. Operational sections describe the actual zkSync flow: deployment via a Forge script + ops/ shell wrapper mirroring ops/deploy_swarm_contracts_zksync.sh, source-code verification via ops/verify_zksync_contracts.py against the zkSync verifier API, and a manual pre-upgrade storage-layout check matching src/swarms/doc/upgradeable-contracts.md. CI today runs forge test on all packages and enforces 95% coverage on swarms only; collection-coverage and storage-layout-diff CI jobs are recorded as deferred items. --- src/collections/doc/README.md | 9 + .../spec/user-collections-specification.md | 767 ++++++++++++++++++ 2 files changed, 776 insertions(+) create mode 100644 src/collections/doc/README.md create mode 100644 src/collections/doc/spec/user-collections-specification.md diff --git a/src/collections/doc/README.md b/src/collections/doc/README.md new file mode 100644 index 00000000..94116f58 --- /dev/null +++ b/src/collections/doc/README.md @@ -0,0 +1,9 @@ +# User Collections — Documentation + +Operator-triggered NFT collection factory: users pay in fiat off-chain, a trusted backend deploys a fully-isolated clone (ERC-721 or ERC-1155) on the user's behalf. + +## Contents + +| Document | Description | +| -------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------ | +| [spec/user-collections-specification.md](spec/user-collections-specification.md) | Full technical specification (architecture, roles, interfaces, flows, storage, security, testing, ops) | diff --git a/src/collections/doc/spec/user-collections-specification.md b/src/collections/doc/spec/user-collections-specification.md new file mode 100644 index 00000000..aaf98cb6 --- /dev/null +++ b/src/collections/doc/spec/user-collections-specification.md @@ -0,0 +1,767 @@ +--- +title: "Nodle User Collections — Technical Specification" +subtitle: "Operator-Triggered NFT Collection Factory with Per-Collection Clone Isolation" +date: "April 2026" +version: "1.0" +--- + +

+ +## 1. Introduction & Architecture + +### 1.1 System Overview + +The User Collections system lets users create their own ERC-721 or ERC-1155 NFT collections on the Nodle zkSync L2. Creation is paid in fiat off-chain; the on-chain deployment is triggered by a trusted backend after the fiat payment clears. Each collection is a fully-isolated minimal proxy clone with its own address, owner, and metadata. + +The on-chain layer provides: + +- A single upgradeable factory that deploys cheap clones of fixed-behavior implementation contracts. +- Two implementation templates (ERC-721 and ERC-1155), both inheriting OpenZeppelin's audited upgradeable primitives. +- Role-scoped permissions: a backend operator can trigger creation and mint into any collection, while creators retain ownership and minting rights on their own collection. +- Reconciliation hooks (`externalId` events and lookup map) so the off-chain payment ledger can deterministically locate the on-chain artifact for every order. + +### 1.2 Architecture + +```mermaid +graph TB + subgraph Off-chain["Off-chain (out of scope)"] + APP(("App /

On each clone, `OWNER_ROLE` administers `MINTER_ROLE` (so the creator can grant additional minters or revoke the operator's minting rights if they wish). + +### 2.3 Operator Minter Convention + +The factory does not auto-grant `MINTER_ROLE` to the configured operator on new clones — the clone has no awareness of the factory's `OPERATOR_ROLE`. The backend must include the operator address in `additionalMinters` when calling `createCollection*` so that operator-mediated minting works for fiat-priced item sales. + +This is enforced by backend convention, not on-chain. Creators can revoke the operator's `MINTER_ROLE` from their own collection at any time via `OWNER_ROLE`. + +

Increments `nextTokenId`, calls `_safeMint`, sets per-token URI via `ERC721URIStorage._setTokenURI`. Returns the new token ID. +- `mintBatch`: `MINTER_ROLE`-gated.

The single `metadataLocked` flag covers both per-collection (`baseURI`) and collection-level (`contractURI`) metadata so that buyers see one verifiable "metadata is frozen" signal across the whole collection. (Per-token URIs minted via `ERC721URIStorage._setTokenURI` are anchored at mint time independently of this flag — see §7.2 row 7.) +- `setDefaultRoyalty`: `OWNER_ROLE`-gated. Reverts `RoyaltiesAreLocked` when `royaltiesLocked == true`. +- `lockMetadata` / `lockRoyalties`: `OWNER_ROLE`-gated, one-way; emit events for indexers. + +### 3.6 `UserCollection1155` + +Mirrors §3.5 with ERC-1155 mechanics: + +- Inherits `Initializable`, `ERC1155Upgradeable`, `ERC1155SupplyUpgradeable`, `ERC1155BurnableUpgradeable`, `ERC2981Upgradeable`, `AccessControlUpgradeable`. +- `mint(address to, uint256 id, uint256 amount, bytes data)` — `MINTER_ROLE`-gated. +- `mintBatch(address to, uint256[] ids, uint256[] amounts, bytes data)` — single recipient, matching OZ's `_mintBatch`. Reverts `BatchTooLarge` when `ids.length > MAX_BATCH` and `LengthMismatch` when `ids.length != amounts.length`. +- `setURI(string newURI)` instead of `setBaseURI`. Subject to `metadataLocked`. +- No `nextTokenId` (1155 IDs are caller-chosen). + +

Deployment & Operations + +### 9.1 Deployment Script + +Two artifacts, mirroring the swarms pattern: + +- `script/DeployCollectionFactoryZkSync.s.sol` — Forge script that performs the on-chain deployment work. +- `ops/deploy_collection_factory_zksync.sh` — orchestration shell script analogous to `ops/deploy_swarm_contracts_zksync.sh`: runs preflight checks, compiles with `forge build --zksync`, calls the Forge script, performs post-deploy `cast` checks, and invokes `ops/verify_zksync_contracts.py` for source-code verification on the zkSync explorer. + +Environment variables (prefixed `N_` per repo convention; consumed by the Forge script): + +| Variable | Description | +| :------------------- | :------------------------------------------------------------- | +| `N_FACTORY_ADMIN` | Multisig address that will hold `DEFAULT_ADMIN_ROLE` | +| `N_FACTORY_OPERATOR` | Backend service address that will hold `OPERATOR_ROLE` | + +Steps performed by the Forge script: + +1. Deploy `UserCollection721` implementation. Constructor calls `_disableInitializers()`. +2. Deploy `UserCollection1155` implementation. Same. +3. Deploy `CollectionFactory` logic. +4. Deploy `ERC1967Proxy` pointing at `CollectionFactory`, with init data calling `initialize(N_FACTORY_ADMIN, N_FACTORY_OPERATOR, impl721, impl1155)`. +5. Log all four addresses (implementation 721, implementation 1155, factory logic, factory proxy) in the same `: 0x...` format that the orchestration script greps for. + +Steps performed by the orchestration shell script (after the Forge script broadcasts): + +6. Sanity-check the deployment with `cast` (admin role granted, operator role granted, both implementation pointers set, UUPS implementation slot points at the factory logic). +7. Verify source code on the zkSync block explorer via `python3 ops/verify_zksync_contracts.py --broadcast broadcast/DeployCollectionFactoryZkSync.s.sol//run-latest.json --verifier-url $VERIFIER_URL --compiler-version 0.8.26 --zksolc-version v1.5.15 --project-root "$PROJECT_ROOT"`. Verifier URLs follow the swarms convention: + - **Mainnet**: `https://zksync2-mainnet-explorer.zksync.io/contract_verification` (explorer at `https://explorer.zksync.io`) + - **Testnet**: `https://explorer.sepolia.era.zksync.dev/contract_verification` (explorer at `https://sepolia.explorer.zksync.io`) +8. Append the deployed addresses to the appropriate `.env-test` / `.env-prod` file (same pattern as the swarms script's `update_env_file` step). +9. Add a usage example to `README.md` under the existing deployment section. + +> **Note on tooling.** The repo's `README.md` still mentions Etherscan as the verification target; that wording predates the zkSync-era flow. The actual operational pattern (used by `ops/deploy_swarm_contracts_zksync.sh`) is: do **not** use `forge script --verify` (it sends absolute paths the zkSync verifier rejects) and do **not** rely on `forge verify-contract` directly (it sends `../` traversal imports the zkSync verifier rejects). Use `ops/verify_zksync_contracts.py`, which generates standard JSON via Forge, rewrites relative imports to project-rooted paths, and submits to the zkSync verifier API. With `bytecode_hash = "none"` already set in `foundry.toml`, this achieves full verification. + +### 9.2 Indexing + +Subquery (`subquery/` package) extension required: + +- **Top-level source**: factory address. Handler on `CollectionCreated` writes a `Collection` entity and dynamically registers the new clone address as a `Transfer`-listening source (subquery dynamic-source pattern). +- **Per-clone handlers**: `Transfer` writes `Token` and `Owner` entities scoped by collection. Lock events (`MetadataLocked`, `RoyaltiesLocked`) update the corresponding `Collection` entity flags for buyer due-diligence. + +Indexer wiring is out of this repo's contract scope but is referenced here so the implementation plan can include a tracking task for the subquery package. + +### 9.3 Paymaster Integration + +The operator account uses the existing `BondTreasuryPaymaster` for L2 gas. The operator must be seeded with bond allowance before first creation; subsequent adjustments use the paymaster's standard admin path. No new paymaster contract is required for this feature. + +### 9.4 Upgrade & Rollback + +| Operation | Procedure | +| :----------------------------------- | :------------------------------------------------------------------------------------------------------------ | +| Upgrade factory logic | Run pre-upgrade checklist (below), then admin calls `factory.upgradeTo(newImpl)` (UUPS) | +| Ship a new ERC-721 template | Deploy new implementation; admin calls `setImplementation721(newImpl)`; affects *future* clones only | +| Ship a new ERC-1155 template | Deploy new implementation; admin calls `setImplementation1155(newImpl)`; affects *future* clones only | +| Rotate operator key | Admin calls `revokeRole(OPERATOR_ROLE, oldKey)` then `grantRole(OPERATOR_ROLE, newKey)` | +| Pause new creations | Admin revokes all addresses from `OPERATOR_ROLE`.

drop OZ v5 no-op inits MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Test coverage for the user collections system: - UserCollection721.t.sol (24 tests): initialize wiring, mint / mintBatch with returned tokenIds asserted contiguous and matching Transfer events, lock semantics on baseURI/contractURI/royalties, role-admin grant + revoke, ERC-2981 non-zero and zero (clear) paths, supportsInterface for ERC-165/721/Metadata/2981/AccessControl, ERC721Burnable scenarios, bytecode-permanence opcode walker (skips PUSH1..PUSH32 immediates). - UserCollection1155.t.sol (18 tests): analogous coverage adapted to ERC-1155 mechanics, including ERC1155Supply / Burnable behavior. - CollectionFactory.t.sol (21 tests): atomic clone+init, externalId reverts, operator auto-grant invariant, setImplementation* validation, and the four UUPS assertions from spec §8.1 — slot change via vm.load, OPERATOR-only rejection, storage preservation through V2 mock, non-UUPS revert via ERC1967InvalidImplementation. - Collections.integration.t.sol: end-to-end happy path from §8.4. - mocks/CollectionFactoryV2Mock.sol + NonUUPSImplementationMock.sol. Drops empty `___init` calls (ERC721URIStorage, Burnable, ERC2981, AccessControl, ERC1155Supply, etc.) which are no-op shims in OZ v5.6.1 kept only as forward-compat aliases. Comment notes to re-add them on OZ upgrade. Functional inits (`__ERC721_init`, `__ERC1155_init`) and `_disableInitializers()` retained. Coverage: 157/162 = 96.91% lines (CollectionFactory 97.78%, UserCollection1155 96.08%, UserCollection721 96.97%).

Includes the full §9.4 pre-upgrade checklist in the natspec. - ops/deploy_collection_factory_zksync.sh: orchestration script that loads .env-test/.env-prod, runs preflight checks, builds with --zksync, invokes the Forge script, performs cast-based post-deploy sanity checks (admin/operator role grants, impl pointers, EIP-1967 slot), delegates source verification to verify_zksync_contracts.py, and appends the deployed addresses to the env file. - src/collections/layouts/{CollectionFactory,UserCollection721, UserCollection1155}.v1.json: storage-layout baselines committed for the §9.4 baseline-JSON convention. Verifies that lock booleans pack into one slot (slot 3 offset 0/1 in 721; slot 1 offset 0/1 in 1155) and that the gap is sized correctly (46 in 721, 47 in 1155 and the factory). - .cspell.json: allow codehash, codehashes, immediates, newbase, newcontract, opping (referenced in test fixtures and contracts). - spec §10: file layout extended to list all three layout baselines. Required env vars per spec §9.1: N_FACTORY_ADMIN (multisig holding DEFAULT_ADMIN_ROLE) and N_FACTORY_OPERATOR (backend service holding OPERATOR_ROLE). --- .cspell.json | 8 +- ops/deploy_collection_factory_zksync.sh | 411 ++++++++++++++++++ script/DeployCollectionFactoryZkSync.s.sol | 90 ++++ script/UpgradeCollectionFactory.s.sol | 127 ++++++ .../spec/user-collections-specification.md | 2 + .../layouts/CollectionFactory.v1.json | 66 +++ .../layouts/UserCollection1155.v1.json | 59 +++ .../layouts/UserCollection721.v1.json | 75 ++++ 8 files changed, 837 insertions(+), 1 deletion(-) create mode 100755 ops/deploy_collection_factory_zksync.sh create mode 100644 script/DeployCollectionFactoryZkSync.s.sol create mode 100644 script/UpgradeCollectionFactory.s.sol create mode 100644 src/collections/layouts/CollectionFactory.v1.json create mode 100644 src/collections/layouts/UserCollection1155.v1.json create mode 100644 src/collections/layouts/UserCollection721.v1.json diff --git a/.cspell.json b/.cspell.json index c1f17aed..3834bdf3 100644 --- a/.cspell.json +++ b/.cspell.json @@ -108,6 +108,12 @@ "runbook", "selfdestruct", "SELFDESTRUCT", - "proxiable" + "proxiable", + "codehash", + "codehashes", + "immediates", + "newbase", + "newcontract", + "opping" ] } diff --git a/ops/deploy_collection_factory_zksync.sh b/ops/deploy_collection_factory_zksync.sh new file mode 100755 index 00000000..a1a99754 --- /dev/null +++ b/ops/deploy_collection_factory_zksync.sh @@ -0,0 +1,411 @@ +#!/bin/bash +# ============================================================================= +# deploy_collection_factory_zksync.sh +# +# Automated deployment script for the user collections system +# (CollectionFactory + UserCollection721 + UserCollection1155) on ZkSync Era. +# +# OVERVIEW: +# --------- +# Deploys the upgradeable user collections system to ZkSync Era using Foundry +# with --zksync (zksolc compiler). +# +# Mirrors the swarms deployment pattern (ops/deploy_swarm_contracts_zksync.sh): +# - Forge build with --zksync, skip tests +# - Run the Forge script via --broadcast (or dry-run without) +# - Source code verification via ops/verify_zksync_contracts.py (the +# ZkSync verifier rejects forge --verify and forge verify-contract) +# - Append deployed addresses to .env-test or .env-prod +# +# Unlike the swarms script, no L1-incompatible files have to be moved out of +# the tree — collections has no SSTORE2/EXTCODECOPY usage. +# +# CONTRACT ARCHITECTURE: +# ---------------------- +# - UserCollection721 implementation (cloned per ERC-721 collection) +# - UserCollection1155 implementation (cloned per ERC-1155 collection) +# - CollectionFactory logic + ERC1967Proxy (UUPS-upgradeable factory) +# +# USAGE: +# ------ +# # Testnet dry run: +# ./ops/deploy_collection_factory_zksync.sh testnet +# +# # Testnet (actual deployment): +# ./ops/deploy_collection_factory_zksync.sh testnet --broadcast +# +# # Mainnet: +# ./ops/deploy_collection_factory_zksync.sh mainnet --broadcast +# +# REQUIRED ENVIRONMENT VARIABLES (loaded from .env-test / .env-prod): +# ------------------------------------------------------------------- +# - DEPLOYER_PRIVATE_KEY: Private key with ETH for gas +# - N_FACTORY_ADMIN: Multisig that will hold DEFAULT_ADMIN_ROLE on the factory +# - N_FACTORY_OPERATOR: Backend service address that will hold OPERATOR_ROLE +# +# ============================================================================= + +set -e # Exit on any error + +# ============================================================================= +# Configuration +# ============================================================================= + +SCRIPT_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)" +PROJECT_ROOT="$(cd "$SCRIPT_DIR/.." && pwd)" + +NETWORK="${1:-testnet}" +BROADCAST="${2:-}" + +case "$NETWORK" in + testnet) + ENV_FILE=".env-test" + EXPLORER_URL="https://sepolia.explorer.zksync.io" + VERIFIER_URL="https://explorer.sepolia.era.zksync.dev/contract_verification" + ;; + mainnet) + ENV_FILE=".env-prod" + EXPLORER_URL="https://explorer.zksync.io" + VERIFIER_URL="https://zksync2-mainnet-explorer.zksync.io/contract_verification" + ;; + *) + echo "Error: Unknown network '$NETWORK'.

docs(collections): design doc for ERC1967Proxy replacement of Clones.clone() Records the spec-level decision and detailed design for swapping per-collection EIP-1167 minimal proxies for canonical OZ ERC1967Proxy with salt=externalId, unblocking zkSync Era deployment. Preserves the per-collection bytecode immutability promise (impls do not inherit UUPSUpgradeable, no ProxyAdmin) and keeps all v1 storage-layout baselines unchanged. Captures spec deltas, test impact, and audit checklist additions for the implementation phase. --- .../2026-05-08-clones-replacement-design.md | 385 ++++++++++++++++++ 1 file changed, 385 insertions(+) create mode 100644 src/collections/doc/spec/2026-05-08-clones-replacement-design.md diff --git a/src/collections/doc/spec/2026-05-08-clones-replacement-design.md b/src/collections/doc/spec/2026-05-08-clones-replacement-design.md new file mode 100644 index 00000000..89594b4a --- /dev/null +++ b/src/collections/doc/spec/2026-05-08-clones-replacement-design.md @@ -0,0 +1,385 @@ +# Collections — Replacing `Clones.clone()` for zkSync Era Compatibility + +**Date:** 2026-05-08 +**Status:** Design (approved through brainstorming; not yet implemented) +**Scope:** `src/collections/` user-collections system +**Driver:** zkSync Sepolia deploy attempt revealed `Clones.clone()` is incompatible with EraVM at runtime +**Related spec:** `src/collections/doc/spec/user-collections-specification.md` + +--- + +## 1. Context + +### 1.1 What we tried + +Running `./ops/deploy_collection_factory_zksync.sh testnet` against zkSync Sepolia (RPC: `https://rpc.ankr.com/zksync_era_sepolia`, chain id 300). The factory + implementations deploy themselves succeeded conceptually — they use Solidity `new`, which zksolc handles correctly — but the per-collection clone path is broken for two independently-confirmed reasons: + +1. **Compiled-artifact evidence.** `zkout/CollectionFactory.sol/CollectionFactory.json` shows `factoryDependencies: {}`. The compiled zk hashes for `UserCollection721` (`010005db…`) and `UserCollection1155` (`0100053b…`) appear zero times in the factory bytecode. zksolc only registers a contract as a `factoryDep` when it sees `type(C).creationCode` or `new C()` *statically* — `Clones.clone(impl)` builds the EIP-1167 runtime blob in memory at runtime, which zksolc never sees. Without a registered factoryDep, EraVM's `ContractDeployer` cannot resolve the deploy. + +2. **Matter Labs confirmation.** From zksync-developers discussion #561, an ML maintainer: *"We don't currently support ERC1167 since we have a different bytecode format."* Production users hitting `Clones.clone()` see `execution reverted: ERC1167: create failed`. Discussions #91, #166, and #561 all end with users refactoring away from `Clones`. + +### 1.2 What's load-bearing + +The user-collections spec (`src/collections/doc/spec/user-collections-specification.md` §1.3) sells per-collection bytecode immutability as the product: + +> *"Already-deployed clones cannot be upgraded — buyers and creators retain a permanent guarantee about each collection's behavior."* + +This is reinforced in §1.4 row 7, §2.3, §6.3, §7.1, and §7.2 row 15. Any replacement for `Clones.clone()` must preserve this property; admin-pushable upgrades to existing collections (e.g. a `BeaconProxy` fleet upgrade) are explicitly out of scope. + +The user has additionally constrained the design to canonical OpenZeppelin patterns — no bespoke proxy or upgrade machinery. + +--- + +## 2. Decision + +**Per-collection `ERC1967Proxy` deployed via `new` with `salt: externalId`, where the implementation contracts do not inherit `UUPSUpgradeable`.** + +```solidity +// inside CollectionFactory.createCollection721 / createCollection1155 +bytes memory initData = abi.encodeCall( + IUserCollection721.initialize, (p, msg.sender) +); +collection = address(new ERC1967Proxy{salt: externalId}(_erc721Implementation, initData)); +``` + +This is the only OZ-standard pattern that simultaneously: + +1. **Preserves the §1.3 immutability promise.** `ERC1967Proxy` is a pure transport. Without `UUPSUpgradeable` on the impl and without a `ProxyAdmin` pattern, the EIP-1967 implementation slot is constructor-fixed and unreachable for write afterward. Three independent gates (no `upgradeToAndCall` selector on the impl, no `ProxyAdmin` slot pattern, `ERC1967Utils.upgradeToAndCall` is `internal` and only callable from inside an impl delegatecall frame that doesn't exist) all have to fail simultaneously for an upgrade to slip through. + +2. **Compiles cleanly on EraVM.** zksolc statically resolves `ERC1967Proxy`, registers its bytecode hash in `CollectionFactory.factoryDependencies`, and lowers `new ERC1967Proxy{salt}(...)` to `ContractDeployer.create2(salt, ERC1967ProxyHash, abi.encode(impl, initData))`. This is the same code path zksolc takes for `new UserCollection721()` in the deploy script — already proven working. + +3. **Has direct precedent in this repo.** `script/DeployCollectionFactoryZkSync.s.sol:72-75` already deploys the *factory itself* as `new ERC1967Proxy(factoryImpl, initData)` on zkSync Era, with atomic delegatecall init in the constructor. The refactor applies the exact same pattern one layer down per collection. + +4. **Enables off-chain address pre-derivation.** With `salt: externalId`, the collection address is a pure function of `(factory, externalId, impl, initData, ERC1967Proxy zk bytecode hash)` — all inputs the backend already controls. The `_collectionByExternalId` mapping remains the canonical on-chain registry; pre-derivation is a redundant lookup path. + +### 2.1 Patterns explicitly rejected + +| Pattern | Rejected because | +|---|---| +| `BeaconProxy` + `UpgradeableBeacon` | Beacon admin can upgrade all collections at once. Violates §1.3. | +| `TransparentUpgradeableProxy` | Has a `ProxyAdmin` with upgrade authority.

Different inputs → different address. + +#### 3.2.4 zkSync compatibility — the three things that have to work, all of which already do + +1. **`new ERC1967Proxy{salt}(impl, initData)` compiles cleanly.** zksolc registers `ERC1967Proxy`'s bytecode hash in the factory's `factoryDependencies`. +2. **`delegatecall` from inside a constructor works on EraVM.** `ERC1967Utils.upgradeToAndCall` does this, and the factory's own deploy already uses this pattern in `script/DeployCollectionFactoryZkSync.s.sol`. +3. **The impl is reached by address, not by factoryDep.** `_erc721Implementation` is passed at runtime, and EraVM resolves the delegatecall target by looking up that address's bytecode on-chain — already registered when the deployer EOA ran `new UserCollection721()` at top level. + +### 3.3 Initialization flow + +``` +new ERC1967Proxy{salt: externalId}(impl, initData) + └── ERC1967Proxy constructor(address logic, bytes _data) + └── ERC1967Utils.upgradeToAndCall(logic, _data) + ├── SSTORE(EIP_1967_IMPL_SLOT, logic) + ├── emit Upgraded(logic) + └── if (_data.length > 0) + └── Address.functionDelegateCall(logic, _data) + └── UserCollection721.initialize(p, operatorMinter) + ├── grants DEFAULT_ADMIN_ROLE / OWNER_ROLE to p.owner + ├── grants MINTER_ROLE to additionalMinters + operatorMinter + ├── sets _baseTokenURI / _contractURI + ├── sets default royalty (if p.royaltyBps > 0) + └── emit Initialized(1) +``` + +Atomic single constructor frame. If any step reverts, the whole `new ERC1967Proxy` reverts and no contract is deployed. Stronger atomicity than the current two-step `Clones.clone()` + `initialize` pattern. + +`_disableInitializers()` in `UserCollection721` / `UserCollection1155` constructors stays unchanged — it hardens the *impl singleton* against ever being directly initialized. The `initializer` modifier on `initialize` still flips `_initialized = 1` in the *proxy's* storage during the constructor's delegatecall, so re-init reverts with OZ's `InvalidInitialization`. + +The operator address travels into `initialize` as the `operatorMinter` parameter, encoded at the call site (`abi.encodeCall(initialize, (p, msg.sender))` in the factory's frame, where `msg.sender` is the OPERATOR_ROLE caller). Identical §2.3 auto-grant semantics. + +### 3.4 Address determinism + +Inputs to the per-collection address derivation: + +``` +addr = ZK_CREATE2( factory, externalId, ERC1967ProxyZkHash, keccak256(abi.encode(impl, initData)) ) +``` + +Where: +- `factory` = the proxy address of `CollectionFactory` (constant per environment). +- `externalId` = the salt, supplied by the operator at create time. +- `ERC1967ProxyZkHash` = the zksolc-emitted bytecode hash of `@openzeppelin/contracts/proxy/ERC1967/ERC1967Proxy.sol`. **Must be pinned in backend artifacts at the version used at factory deploy time.** +- `impl` = the current `_erc721Implementation` (or 1155). Reads via `erc721Implementation()` / `erc1155Implementation()`. +- `initData` = `abi.encodeCall(initialize, (p, operator))`. + +Backend pre-derivation flow: + +1. Read `_erc721Implementation` once (cache; refresh after admin upgrades). +2. Pin `ERC1967ProxyZkHash` from the factory deploy artifacts. +3. Generate `externalId`. +4. Construct `params` and select the operator address. +5. Compute the address using `zksync-ethers` `utils.create2Address`. +6. Submit `createCollection721(params, externalId)` from the operator key. +7. Verify the on-chain `_collectionByExternalId[externalId]` matches the precomputed address (sanity check, not load-bearing). + +#### 3.4.1 Caveats (operational) + +1. **Address is sensitive to every input.** Same `externalId` but different `params` → different address. Backends must fix params before generating the externalId. +2. **Operator rotation note (§2.3).** Because `msg.sender` enters `initData`, two operators calling with the same externalId would derive different addresses. In practice `_checkExternalId` rejects the second call (`DuplicateExternalId`); pre-derivation must use the *current* OPERATOR_ROLE holder. +3. **`_collectionByExternalId` mapping stays canonical.** Pre-derivation is a redundant off-chain lookup path, not a replacement for the on-chain registry. +4. **zk bytecode hash pinning.** Upgrading zksolc can change `ERC1967Proxy`'s zk bytecode hash. Pin the hash to the version used at factory deploy time and only refresh during a coordinated tooling bump. + +### 3.5 Bytecode-permanence invariants + +Existing §7.2 row 15 splits into two clearer sub-rows: + +#### 3.5.1 Row 15a — Implementation bytecode permanence (unchanged) + +`UserCollection721` / `UserCollection1155` are deployed exactly as before: +- Top-level `new` from the deployer EOA in `DeployCollectionFactoryZkSync.s.sol` → sequential `CREATE`, never `CREATE2`. +- `_disableInitializers()` in their constructors. +- No `SELFDESTRUCT` opcode anywhere in own or inherited code. +- No `delegatecall` to caller-provided addresses. + +The opcode-walker bytecode-permanence test continues to run against both impls, with the same assertion set. + +#### 3.5.2 Row 15b — Per-collection proxy permanence (new) + +Per-collection proxies are deployed via `CREATE2` (`{salt: externalId}`). Permanence comes from a different chain of arguments: + +1. **The deployed bytecode is canonical OZ `ERC1967Proxy`, used unmodified.** Imported from `@openzeppelin/contracts/proxy/ERC1967/ERC1967Proxy.sol`, no fork, no override. `ERC1967Proxy` and its dependency `Proxy.sol` contain no `SELFDESTRUCT`. +2. **The impl pointer in the EIP-1967 slot is set exactly once at construction and is unreachable for write afterward.** Three independent gates, all of which would have to fail simultaneously for an upgrade to slip through: + - **(2a)** The implementations do not inherit `UUPSUpgradeable` → no `upgradeToAndCall` selector exposed by the impl. + - **(2b)** We use `ERC1967Proxy` directly, not `TransparentUpgradeableProxy` → no `ProxyAdmin`. + - **(2c)** `ERC1967Utils.upgradeToAndCall` is `internal`, only callable from a delegatecall frame whose code is the impl — and since (2a) holds, no caller can ever reach it. +3. **`CREATE2` re-occupation is foreclosed.** For an attacker to re-occupy a deployed collection's address via salt collision, the existing contract would have to first cease to exist (`SELFDESTRUCT`) — but `ERC1967Proxy` has no such opcode (per (1)) and the impl pointer can't be swapped to one that does (per (2)). On EraVM, `ContractDeployer` additionally enforces "one deployment per address" at the protocol layer; the in-bytecode argument alone is sufficient. + +### 3.6 Spec doc deltas + +#### 3.6.1 Stays verbatim (with single-word `clones → collections` substitution) + +§1.3 immutability promise, §2 entire roles/auth model, §3.5/§3.6 method signatures and lock semantics, §5 mint flows, §6.1 factory storage layout, §6.3 storage-layout discipline, §7.1 trust assumptions, §7.3/§7.4 out-of-scope and audit posture, §9.1 "Deploy `UserCollection721` implementation via `CREATE` (sequential nonce, **never** `CREATE2`)" rule. + +#### 3.6.2 Substantive content rewrites + +| Section | Current | Updated | +|---|---|---| +| §1.1 line 46 | "deploys cheap clones of fixed-behavior implementation contracts" | "deploys per-collection `ERC1967Proxy` instances pointing at fixed-behavior implementation contracts" | +| §1.2 mermaid diagram | subgraph `"User Collections (EIP-1167 minimal proxies)"`, arrow labels `"Clones.clone"` | subgraph `"User Collections (ERC1967Proxy per collection)"`, arrow labels `"new ERC1967Proxy{salt: externalId}"` | +| §1.3 core components table | "EIP-1167 clone target" rows for 721/1155 | "`ERC1967Proxy` implementation" | +| §1.4 row 2 (Deployment model) | "EIP-1167 minimal proxy clones for both standards" | "Per-collection `ERC1967Proxy` deployed via `CREATE2` with `externalId` salt; implementations deployed via `CREATE` only" | +| §1.4 row 7 (Upgradeability) | "Clones: immutable; admin can swap implementation pointer for *future* clones only" | "Per-collection proxies: immutable (impls do not inherit `UUPSUpgradeable`, no admin slot); admin can swap implementation pointer for *future* collections only" | +| §3.4 createCollection atomic-flow bullet | `Clones.clone(impl) → clone.initialize(p, msg.sender) → collectionByExternalId[externalId] = clone` | `abi.encodeCall(initialize, (p, msg.sender)) → new ERC1967Proxy{salt: externalId}(impl, initData) → collectionByExternalId[externalId] = collection`; init is atomic in the proxy constructor | +| §4.1 sequence diagram | `FAC->>CL: Clones.clone(...)` and a separate `CL->>CL: initialize(...)` | Single `FAC->>CL: new ERC1967Proxy{salt}(impl, encodeCall(initialize,(p,msg.sender)))`, with note that `Upgraded(impl)` then `Initialized(1)` events fire inside the constructor | +| §4.2 Atomicity | Current text emphasizes 2-step atomicity within the same tx | Strengthen: deploy + init are now a single constructor frame, no transient uninitialized window | +| §4.4 Gas Profile | "Deploys an EIP-1167 minimal proxy (~45,000 gas on EVM L1 baseline)" | Delete the L1 anchor; replace with "On zkSync Era, per-collection deploy is dominated by `ContractDeployer.create2` + the constructor's delegatecall init; gas measured by `Collections.integration.t.sol` and quoted from the test output (target: < 1.5M gas on zkSync Sepolia for a typical `createCollection721`)" | +| §6.2 Clone Storage opening sentence | "Each clone owns its full storage independently of other clones (EIP-1167 proxies `delegatecall` logic but persist state in the proxy's own address)." | "Each collection owns its full storage independently (`ERC1967Proxy` `delegatecall`s logic at the address in the EIP-1967 implementation slot but persists state in the proxy's own address)." | +| §6.2 gap reservation note | s/clones/collections/g | (same point holds — the EIP-1967 slot doesn't fight the gap because it's at a fixed namespaced slot, not slot N) | + +#### 3.6.3 Additions + +1. **§1.4 row 7 footnote** explaining the OZ-standards rationale: "We use `ERC1967Proxy` directly (not `TransparentUpgradeableProxy`, not `BeaconProxy`) because the implementation contracts deliberately do not inherit `UUPSUpgradeable`.

OZ behavior left unmodified throughout. F1 (metadata): correct the false "per-token URI anchored post-mint" claim. With a non-empty baseURI, OZ resolves tokenURI = baseURI + suffix and base is mutable until lockMetadata. Adopt option (b): callers pass relative suffixes; fix the double-prefix test; add a repoint-demonstrating test; update spec §7.2 row 7 / §3.5 and contract NatSpec. F2 (royalty observability): add DefaultRoyaltyUpdated event (ERC-2981 is event-less) on both impls + interfaces; assert it in tests. F3 (permanence on EraVM): the EVM opcode-walker does not cover the zksolc artifact; add verify_implementation_permanence ABI gate to the deploy script (no upgradeTo*/proxiableUUID selectors); document EVM-vs-EraVM. F4 (role finality): document the intentional no-DEFAULT_ADMIN_ROLE design and OWNER_ROLE non-transferability (spec §2.4 + NatSpec). F5 (mintBatch reentrancy): reserve the 721 ID range before the _safeMint loop so a reentrant mint takes a fresh ID; add regression test. F6 (factory invariant): pin the "initialize makes no external calls" requirement that keeps the registry-write-after-deploy reentrancy-safe. Also lands previously-uncommitted unit-test gap coverage (initialize guard branches, cross-standard externalId collision, 1155 onlyOperator, mintBatch boundary + empty cases). 85/85 collections tests pass; forge build + lint + spellcheck clean. --- .cspell.json | 4 +- ops/deploy_collection_factory_zksync.sh | 48 +++++++++ src/collections/CollectionFactory.sol | 10 ++ src/collections/UserCollection1155.sol | 11 +++ src/collections/UserCollection721.sol | 26 ++++- .../spec/user-collections-specification.md | 19 +++- .../interfaces/IUserCollection1155.sol | 7 ++ .../interfaces/IUserCollection721.sol | 7 ++ test/collections/CollectionFactory.t.sol | 47 +++++++++ test/collections/UserCollection1155.t.sol | 31 ++++++ test/collections/UserCollection721.t.sol | 98 ++++++++++++++++++- .../mocks/ReentrantERC721Receiver.sol | 33 +++++++ 12 files changed, 332 insertions(+), 9 deletions(-) create mode 100644 test/collections/mocks/ReentrantERC721Receiver.sol diff --git a/.cspell.json b/.cspell.json index ccd7449d..0d526e26 100644 --- a/.cspell.json +++ b/.cspell.json @@ -153,6 +153,8 @@ "remappings", "staticcall", "agentic", - "delegatecalls" + "delegatecalls", + "repoints", + "reentrant" ] } diff --git a/ops/deploy_collection_factory_zksync.sh b/ops/deploy_collection_factory_zksync.sh index 22ffb778..03221819 100755 --- a/ops/deploy_collection_factory_zksync.sh +++ b/ops/deploy_collection_factory_zksync.sh @@ -245,6 +245,53 @@ verify_build_artifacts() { log_success "factoryDependencies populated ($dep_count entries)" } +# ============================================================================= +# Implementation permanence (EraVM artifact gate). +# +# The Foundry opcode-walker test (test/collections/*.t.sol) asserts "no +# SELFDESTRUCT" against the EVM-compiled bytecode.

Add a _norm_addr helper to compare padded slot words to addresses. - M1: smoke test asserts the collection's EIP-1967 slot equals the expected 721 impl (was logged but unchecked). - M3: interactive YES confirmation before any mainnet broadcast (bypass with CONFIRM_MAINNET=YES for CI). - M4: skip the smoke test on mainnet by default (it creates a permanent collection); opt in with RUN_MAINNET_SMOKE_TEST=true. - L1/L2/L3: document optional env vars, drop a dead `cast keccak ""` line, make verifier compiler/zksolc versions overridable. Verifier wiring (ops/verify_zksync_contracts.py): the deploy script calls this for source verification, but it had no mapping for the collections contracts — it would resolve 0 contracts, verify nothing, and report success. Fix: - Add CollectionFactory / UserCollection721 / UserCollection1155 to CONTRACT_SOURCE_MAP and a DeployCollectionFactoryZkSync.s.sol deploy-order sequence to BROADCAST_CONTRACT_SEQUENCE. - Fail loudly (exit 2) when a broadcast maps to zero verifiable contracts. - Guard the python call in verify_source_code with `|| exit_code=$?` so verification failure stays non-fatal under set -e instead of aborting. Upgrade script docs (script/UpgradeCollectionFactory.s.sol): - M2: usage examples now include the required --zksync (+ --slow) and document the L1-file move/restore compile prerequisite. bash -n, python py_compile, and a synthetic broadcast-parse check all pass. --- ops/deploy_collection_factory_zksync.sh | 105 ++++++++++++++++++++++-- ops/verify_zksync_contracts.py | 23 ++++++ script/UpgradeCollectionFactory.s.sol | 17 +++- 3 files changed, 132 insertions(+), 13 deletions(-) diff --git a/ops/deploy_collection_factory_zksync.sh b/ops/deploy_collection_factory_zksync.sh index 03221819..dfc8c640 100755 --- a/ops/deploy_collection_factory_zksync.sh +++ b/ops/deploy_collection_factory_zksync.sh @@ -45,9 +45,28 @@ # - N_FACTORY_ADMIN: Multisig that will hold DEFAULT_ADMIN_ROLE on the factory # - N_FACTORY_OPERATOR: Backend service address that will hold OPERATOR_ROLE # +# OPTIONAL ENVIRONMENT VARIABLES: +# ------------------------------- +# - L2_RPC: Override the default zkSync RPC URL for the network +# - OPERATOR_PRIVATE_KEY: Key holding OPERATOR_ROLE, used to sign the post-deploy +# createCollection721 smoke test.

From 982de47471187f745a9ef6df5295d8259f4063d8 Mon Sep 17 00:00:00 2001 From: douglasacost Date: Mon, 1 Jun 2026 15:08:55 -0400 Subject: [PATCH 30/36] ops(collections): add upgrade orchestration wrapper MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ops/upgrade_collection_factory_zksync.sh drives UpgradeCollectionFactory.s.sol through the same safety scaffolding the deploy uses, for all three actions (UPGRADE_FACTORY / SET_IMPL_721 / SET_IMPL_1155): - L1-file move/restore + --zksync compile - action-specific artifact gate (factoryDeps for the factory; no upgrade selectors for collection impls) - pre-upgrade storage-layout diff vs the committed baseline (refuses to broadcast a non-append-only change without LAYOUT_REVIEWED=YES / interactive ack) - admin-key pre-check, mainnet confirmation guard - post-broadcast asserts (EIP-1967 slot / role / impl-pointer preservation) - single-contract source verification of the new impl Docs: point the Forge script NatSpec and spec §9.4/§10 at the wrapper. Validated: bash -n, action validation, _norm_addr, and the storage-layout diff logic (match + drift) all checked. --- ops/upgrade_collection_factory_zksync.sh | 576 ++++++++++++++++++ script/UpgradeCollectionFactory.s.sol | 14 +- .../spec/user-collections-specification.md | 18 +- 3 files changed, 599 insertions(+), 9 deletions(-) create mode 100755 ops/upgrade_collection_factory_zksync.sh diff --git a/ops/upgrade_collection_factory_zksync.sh b/ops/upgrade_collection_factory_zksync.sh new file mode 100755 index 00000000..3f5955e4 --- /dev/null +++ b/ops/upgrade_collection_factory_zksync.sh @@ -0,0 +1,576 @@ +#!/bin/bash +# ============================================================================= +# upgrade_collection_factory_zksync.sh +# +# Orchestration wrapper for upgrading the user collections system on ZkSync Era. +# Companion to ops/deploy_collection_factory_zksync.sh; drives +# script/UpgradeCollectionFactory.s.sol through the same safety scaffolding the +# deploy uses (L1-file move/restore, --zksync compile, artifact gates, mainnet +# guard, post-broadcast asserts, source verification). +# +# THREE ACTIONS (see spec §9.4 and the Forge script's NatSpec): +# UPGRADE_FACTORY Deploy new CollectionFactory logic + upgradeToAndCall on the +# proxy.

Folds in this iteration's outcome: the security hardening (royalty event, mintBatch reentrancy reservation, metadata-URI option-b convention, role finality), the interface cleanup (initialize dropped from ICollectionFactory; custom-surface-only interfaces), address pre-derivation (validated on Sepolia), the Foundry+Hardhat deploy paths and the verification tooling split (factoryDeps vs bare ERC1967Proxy; zksolc 1.5.15 alignment), and the on-demand storage-layout approach (no committed baselines).

The factory + implementations deploy themselves succeeded conceptually — they use Solidity `new`, which zksolc handles correctly — but the per-collection clone path is broken for two independently-confirmed reasons: - -1. **Compiled-artifact evidence.** `zkout/CollectionFactory.sol/CollectionFactory.json` shows `factoryDependencies: {}`. The compiled zk hashes for `UserCollection721` (`010005db…`) and `UserCollection1155` (`0100053b…`) appear zero times in the factory bytecode. zksolc only registers a contract as a `factoryDep` when it sees `type(C).creationCode` or `new C()` *statically* — `Clones.clone(impl)` builds the EIP-1167 runtime blob in memory at runtime, which zksolc never sees. Without a registered factoryDep, EraVM's `ContractDeployer` cannot resolve the deploy. - -2. **Matter Labs confirmation.** From zksync-developers discussion #561, an ML maintainer: *"We don't currently support ERC1167 since we have a different bytecode format."* Production users hitting `Clones.clone()` see `execution reverted: ERC1167: create failed`. Discussions #91, #166, and #561 all end with users refactoring away from `Clones`. - -### 1.2 What's load-bearing - -The user-collections spec (`src/collections/doc/spec/user-collections-specification.md` §1.3) sells per-collection bytecode immutability as the product: - -> *"Already-deployed clones cannot be upgraded — buyers and creators retain a permanent guarantee about each collection's behavior."* - -This is reinforced in §1.4 row 7, §2.3, §6.3, §7.1, and §7.2 row 15.

Without `UUPSUpgradeable` on the impl and without a `ProxyAdmin` pattern, the EIP-1967 implementation slot is constructor-fixed and unreachable for write afterward. Three independent gates (no `upgradeToAndCall` selector on the impl, no `ProxyAdmin` slot pattern, `ERC1967Utils.upgradeToAndCall` is `internal` and only callable from inside an impl delegatecall frame that doesn't exist) all have to fail simultaneously for an upgrade to slip through. - -2. **Compiles cleanly on EraVM.** zksolc statically resolves `ERC1967Proxy`, registers its bytecode hash in `CollectionFactory.factoryDependencies`, and lowers `new ERC1967Proxy{salt}(...)` to `ContractDeployer.create2(salt, ERC1967ProxyHash, abi.encode(impl, initData))`. This is the same code path zksolc takes for `new UserCollection721()` in the deploy script — already proven working. - -3. **Has direct precedent in this repo.** `script/DeployCollectionFactoryZkSync.s.sol:72-75` already deploys the *factory itself* as `new ERC1967Proxy(factoryImpl, initData)` on zkSync Era, with atomic delegatecall init in the constructor. The refactor applies the exact same pattern one layer down per collection. - -4. **Enables off-chain address pre-derivation.** With `salt: externalId`, the collection address is a pure function of `(factory, externalId, impl, initData, ERC1967Proxy zk bytecode hash)` — all inputs the backend already controls. The `_collectionByExternalId` mapping remains the canonical on-chain registry; pre-derivation is a redundant lookup path. - -### 2.1 Patterns explicitly rejected - -| Pattern | Rejected because | -|---|---| -| `BeaconProxy` + `UpgradeableBeacon` | Beacon admin can upgrade all collections at once.

Different inputs → different address. - -#### 3.2.4 zkSync compatibility — the three things that have to work, all of which already do - -1. **`new ERC1967Proxy{salt}(impl, initData)` compiles cleanly.** zksolc registers `ERC1967Proxy`'s bytecode hash in the factory's `factoryDependencies`. -2. **`delegatecall` from inside a constructor works on EraVM.** `ERC1967Utils.upgradeToAndCall` does this, and the factory's own deploy already uses this pattern in `script/DeployCollectionFactoryZkSync.s.sol`. -3. **The impl is reached by address, not by factoryDep.** `_erc721Implementation` is passed at runtime, and EraVM resolves the delegatecall target by looking up that address's bytecode on-chain — already registered when the deployer EOA ran `new UserCollection721()` at top level. - -### 3.3 Initialization flow - -``` -new ERC1967Proxy{salt: externalId}(impl, initData) - └── ERC1967Proxy constructor(address logic, bytes _data) - └── ERC1967Utils.upgradeToAndCall(logic, _data) - ├── SSTORE(EIP_1967_IMPL_SLOT, logic) - ├── emit Upgraded(logic) - └── if (_data.length > 0) - └── Address.functionDelegateCall(logic, _data) - └── UserCollection721.initialize(p, operatorMinter) - ├── grants DEFAULT_ADMIN_ROLE / OWNER_ROLE to p.owner - ├── grants MINTER_ROLE to additionalMinters + operatorMinter - ├── sets _baseTokenURI / _contractURI - ├── sets default royalty (if p.royaltyBps > 0) - └── emit Initialized(1) -``` - -Atomic single constructor frame. If any step reverts, the whole `new ERC1967Proxy` reverts and no contract is deployed. Stronger atomicity than the current two-step `Clones.clone()` + `initialize` pattern. - -`_disableInitializers()` in `UserCollection721` / `UserCollection1155` constructors stays unchanged — it hardens the *impl singleton* against ever being directly initialized. The `initializer` modifier on `initialize` still flips `_initialized = 1` in the *proxy's* storage during the constructor's delegatecall, so re-init reverts with OZ's `InvalidInitialization`. - -The operator address travels into `initialize` as the `operatorMinter` parameter, encoded at the call site (`abi.encodeCall(initialize, (p, msg.sender))` in the factory's frame, where `msg.sender` is the OPERATOR_ROLE caller). Identical §2.3 auto-grant semantics. - -### 3.4 Address determinism - -Inputs to the per-collection address derivation: - -``` -addr = ZK_CREATE2( factory, externalId, ERC1967ProxyZkHash, keccak256(abi.encode(impl, initData)) ) -``` - -Where: -- `factory` = the proxy address of `CollectionFactory` (constant per environment). -- `externalId` = the salt, supplied by the operator at create time. -- `ERC1967ProxyZkHash` = the zksolc-emitted bytecode hash of `@openzeppelin/contracts/proxy/ERC1967/ERC1967Proxy.sol`. **Must be pinned in backend artifacts at the version used at factory deploy time.** -- `impl` = the current `_erc721Implementation` (or 1155). Reads via `erc721Implementation()` / `erc1155Implementation()`. -- `initData` = `abi.encodeCall(initialize, (p, operator))`. - -Backend pre-derivation flow: - -1. Read `_erc721Implementation` once (cache; refresh after admin upgrades). -2. Pin `ERC1967ProxyZkHash` from the factory deploy artifacts. -3. Generate `externalId`. -4. Construct `params` and select the operator address. -5. Compute the address using `zksync-ethers` `utils.create2Address`. -6. Submit `createCollection721(params, externalId)` from the operator key. -7. Verify the on-chain `_collectionByExternalId[externalId]` matches the precomputed address (sanity check, not load-bearing). - -#### 3.4.1 Caveats (operational) - -1. **Address is sensitive to every input.** Same `externalId` but different `params` → different address. Backends must fix params before generating the externalId. -2. **Operator rotation note (§2.3).** Because `msg.sender` enters `initData`, two operators calling with the same externalId would derive different addresses. In practice `_checkExternalId` rejects the second call (`DuplicateExternalId`); pre-derivation must use the *current* OPERATOR_ROLE holder. -3. **`_collectionByExternalId` mapping stays canonical.** Pre-derivation is a redundant off-chain lookup path, not a replacement for the on-chain registry. -4. **zk bytecode hash pinning.** Upgrading zksolc can change `ERC1967Proxy`'s zk bytecode hash.

Permanence comes from a different chain of arguments: - -1. **The deployed bytecode is canonical OZ `ERC1967Proxy`, used unmodified.** Imported from `@openzeppelin/contracts/proxy/ERC1967/ERC1967Proxy.sol`, no fork, no override. `ERC1967Proxy` and its dependency `Proxy.sol` contain no `SELFDESTRUCT`. -2. **The impl pointer in the EIP-1967 slot is set exactly once at construction and is unreachable for write afterward.** Three independent gates, all of which would have to fail simultaneously for an upgrade to slip through: - - **(2a)** The implementations do not inherit `UUPSUpgradeable` → no `upgradeToAndCall` selector exposed by the impl. - - **(2b)** We use `ERC1967Proxy` directly, not `TransparentUpgradeableProxy` → no `ProxyAdmin`. - - **(2c)** `ERC1967Utils.upgradeToAndCall` is `internal`, only callable from a delegatecall frame whose code is the impl — and since (2a) holds, no caller can ever reach it. -3. **`CREATE2` re-occupation is foreclosed.** For an attacker to re-occupy a deployed collection's address via salt collision, the existing contract would have to first cease to exist (`SELFDESTRUCT`) — but `ERC1967Proxy` has no such opcode (per (1)) and the impl pointer can't be swapped to one that does (per (2)). On EraVM, `ContractDeployer` additionally enforces "one deployment per address" at the protocol layer; the in-bytecode argument alone is sufficient. - -### 3.6 Spec doc deltas - -#### 3.6.1 Stays verbatim (with single-word `clones → collections` substitution) - -§1.3 immutability promise, §2 entire roles/auth model, §3.5/§3.6 method signatures and lock semantics, §5 mint flows, §6.1 factory storage layout, §6.3 storage-layout discipline, §7.1 trust assumptions, §7.3/§7.4 out-of-scope and audit posture, §9.1 "Deploy `UserCollection721` implementation via `CREATE` (sequential nonce, **never** `CREATE2`)" rule. - -#### 3.6.2 Substantive content rewrites - -| Section | Current | Updated | -|---|---|---| -| §1.1 line 46 | "deploys cheap clones of fixed-behavior implementation contracts" | "deploys per-collection `ERC1967Proxy` instances pointing at fixed-behavior implementation contracts" | -| §1.2 mermaid diagram | subgraph `"User Collections (EIP-1167 minimal proxies)"`, arrow labels `"Clones.clone"` | subgraph `"User Collections (ERC1967Proxy per collection)"`, arrow labels `"new ERC1967Proxy{salt: externalId}"` | -| §1.3 core components table | "EIP-1167 clone target" rows for 721/1155 | "`ERC1967Proxy` implementation" | -| §1.4 row 2 (Deployment model) | "EIP-1167 minimal proxy clones for both standards" | "Per-collection `ERC1967Proxy` deployed via `CREATE2` with `externalId` salt; implementations deployed via `CREATE` only" | -| §1.4 row 7 (Upgradeability) | "Clones: immutable; admin can swap implementation pointer for *future* clones only" | "Per-collection proxies: immutable (impls do not inherit `UUPSUpgradeable`, no admin slot); admin can swap implementation pointer for *future* collections only" | -| §3.4 createCollection atomic-flow bullet | `Clones.clone(impl) → clone.initialize(p, msg.sender) → collectionByExternalId[externalId] = clone` | `abi.encodeCall(initialize, (p, msg.sender)) → new ERC1967Proxy{salt: externalId}(impl, initData) → collectionByExternalId[externalId] = collection`; init is atomic in the proxy constructor | -| §4.1 sequence diagram | `FAC->>CL: Clones.clone(...)` and a separate `CL->>CL: initialize(...)` | Single `FAC->>CL: new ERC1967Proxy{salt}(impl, encodeCall(initialize,(p,msg.sender)))`, with note that `Upgraded(impl)` then `Initialized(1)` events fire inside the constructor | -| §4.2 Atomicity | Current text emphasizes 2-step atomicity within the same tx | Strengthen: deploy + init are now a single constructor frame, no transient uninitialized window | -| §4.4 Gas Profile | "Deploys an EIP-1167 minimal proxy (~45,000 gas on EVM L1 baseline)" | Delete the L1 anchor; replace with "On zkSync Era, per-collection deploy is dominated by `ContractDeployer.create2` + the constructor's delegatecall init; gas measured by `Collections.integration.t.sol` and quoted from the test output (target: < 1.5M gas on zkSync Sepolia for a typical `createCollection721`)" | -| §6.2 Clone Storage opening sentence | "Each clone owns its full storage independently of other clones (EIP-1167 proxies `delegatecall` logic but persist state in the proxy's own address)." | "Each collection owns its full storage independently (`ERC1967Proxy` `delegatecall`s logic at the address in the EIP-1967 implementation slot but persists state in the proxy's own address)." | -| §6.2 gap reservation note | s/clones/collections/g | (same point holds — the EIP-1967 slot doesn't fight the gap because it's at a fixed namespaced slot, not slot N) | - -#### 3.6.3 Additions - -1. **§1.4 row 7 footnote** explaining the OZ-standards rationale: "We use `ERC1967Proxy` directly (not `TransparentUpgradeableProxy`, not `BeaconProxy`) because the implementation contracts deliberately do not inherit `UUPSUpgradeable`.

This is the empirical end-to-end check that the zksolc-compiled output works at runtime on EraVM — the precise gap that left us with a passing dry-run but a broken `Clones.clone()` flow originally. - -#### 3.8.4 CI build-artifact check (not a Foundry test) - -Add to the deploy script (or the existing CI workflow): - -```bash -test "$(jq -r '.factoryDependencies | length' zkout/CollectionFactory.sol/CollectionFactory.json)" -gt 0 -``` - -If `factoryDependencies` is ever empty again on the factory, the build fails immediately — the smoking-gun signal we used to detect the original `Clones.clone()` problem becomes a permanent guardrail. - -#### 3.8.5 Coverage - -Current 96.91%.

The impls do **not** inherit `UUPSUpgradeable` → no `upgradeToAndCall` / `proxiableUUID` selector exposed. +2. We use `ERC1967Proxy` directly, not `TransparentUpgradeableProxy` → no `ProxyAdmin`. +3. `ERC1967Utils.upgradeToAndCall` is `internal` — callable only from a delegatecall frame whose code is the impl, and by (1) no such frame exists. + +Plus: the deployed bytecode is **canonical, unmodified OZ `ERC1967Proxy`** (no `SELFDESTRUCT`), and on EraVM `ContractDeployer` enforces one-deployment-per-address. + +### 3.3 EVM-vs-EraVM verification note +The Foundry opcode-walker runs against **EVM** bytecode (Foundry's default backend), not the shipped **EraVM** artifact. That's acceptable because EraVM doesn't support `selfdestruct` at the VM level. As a VM-agnostic guard on the *deployed* artifact, the deploy script (`ops/deploy_collection_factory_zksync.sh`, `verify_implementation_permanence`) asserts the zksolc ABI of both impls exposes **no** `upgradeTo*`/`proxiableUUID` selector — catching any accidental future `UUPSUpgradeable` inheritance. + +--- + +## 4. Address determinism & pre-derivation + +Per-collection addresses are deterministic and **pre-derivable off-chain before creation** (validated end-to-end on Sepolia: predicted address == deployed address). The zkSync CREATE2 derivation is a pure function of: + +- `sender` = the factory proxy address +- `bytecodeHash` = `utils.hashBytecode(ERC1967Proxy)` — pin to the zksolc version used at deploy time +- `salt` = `externalId` +- `input` = `abi.encode(impl, initData)`, where `initData = initialize(CreateParams, operator)` + +Backend flow (`zksync-ethers` `utils.create2Address`): +1. Read `erc721Implementation()` (cache; refresh after admin swaps). +2. Pin `ERC1967Proxy` zk bytecode hash from the factory deploy artifacts. +3. Fix `params`, choose the **current** `OPERATOR_ROLE` holder, generate `externalId`. +4. Compute the address; show it to the user before broadcasting. + +**Caveats:** the address is sensitive to *every* input — different params, operator, or impl → different address. The on-chain `collectionByExternalId` mapping stays canonical; pre-derivation is a convenience, not a replacement. + +--- + +## 5. Implementation details (as built) + +### 5.1 Roles +- **Factory:** `DEFAULT_ADMIN_ROLE` (admin Safe — upgrades, role admin, impl-pointer swaps), `OPERATOR_ROLE` (backend — `createCollection*`). +- **Per collection:** `OWNER_ROLE` (creator — metadata/royalty/minter management), `MINTER_ROLE` (creator + operator + `additionalMinters`). `OWNER_ROLE` admins `MINTER_ROLE`. +- **Operator auto-grant (§2.3):** the factory passes `msg.sender` into `initialize`, which unconditionally grants it `MINTER_ROLE` — a contract-level invariant, not a backend convention. +- **Role finality (§2.4):** collections are created with **no `DEFAULT_ADMIN_ROLE` holder**. `OWNER_ROLE` is its own non-transferable anchor; owner key loss permanently freezes owner-only functions (tokens/minting unaffected). Intentional. + +### 5.2 Custom surface vs OZ +The contracts inherit the full OZ `*Upgradeable` stack (ERC721/1155 + URIStorage/Supply + Burnable + ERC2981 + AccessControl). OZ ships **only `internal` hooks** (`_mint`, `_setURI`, `_baseURI`, `_setDefaultRoyalty`); the public `mint`/`mintBatch`/`setBaseURI`/`setURI`/`setContractURI`/`setDefaultRoyalty`/`lock*`/views are **our** access-gated wrappers. These (plus custom errors/events) are what the interfaces declare — the interfaces never re-declare OZ-provided public methods. `initialize` stays in `IUserCollection721/1155` (the factory encodes against it) but was removed from `ICollectionFactory` (no consumer; it's the `Initializable` deploy hook). + +The contracts remain **fully ERC-721 / ERC-1155 compliant** — the custom functions are additive. + +### 5.3 Owner-controlled anti-rug locks +`lockMetadata()` / `lockRoyalties()` are one-way, independent switches (emit events for indexers). After `lockMetadata`, `setBaseURI`/`setURI`/`setContractURI` revert; after `lockRoyalties`, `setDefaultRoyalty` reverts. **Unlocked by default** — locking is a deliberate, credible on-chain commitment the creator makes when ready (default-locked would make the setters dead and break reveals/fixes). Not part of any ERC — a custom buyer-protection mechanism. + +### 5.4 Metadata-URI convention (option b) +With a non-empty `baseURI`, OZ `ERC721URIStorage` resolves `tokenURI(id) = baseURI + perTokenSuffix`. Callers pass a **relative suffix** to `mint`/`mintBatch`. The per-token suffix is fixed at mint, but the shared `baseURI` is mutable until `lockMetadata` — so **only `metadataLocked` provides a freeze guarantee**, not the per-token suffix alone (validated on-chain: `tokenURI(0) = "ipfs://smoke/1.json"`). + +### 5.5 Security hardening (review findings, all applied) +- **Royalty observability** — `setDefaultRoyalty` emits `DefaultRoyaltyUpdated` (ERC-2981 is event-less) so indexers can track royalty changes. +- **`mintBatch` reentrancy** — the 721 batch reserves its ID range *before* the `_safeMint` loop, so a reentrant mint takes a fresh ID instead of relying on OZ's duplicate-mint revert (regression test included). +- **Factory invariant** — the `externalId → collection` registry write trails the deploy+init and is reentrancy-safe *only* while `initialize` makes no external calls; pinned in a code comment for future impls. +- **Fail-closed inputs** — `royaltyBps > 0` with a zero recipient, or `> 10000`, revert the whole `createCollection*` (OZ ERC-2981). + +### 5.6 Storage layout +Under OZ v5 ERC-7201 namespaced storage, the inherited mixins occupy keccak-derived slots; the contracts' own variables start at slot 0. The two lock bools pack into one slot. `__gap` reserves headroom for future appended fields when an admin swaps the impl pointer for future collections. + +--- + +## 6.
