Walkthrough

Added quorum-based STARK-curve multisig interfaces and account components. The change includes signer and quorum management, canonical signature validation, storage packing, macro and test support, and the MultisigAccountUpgradeable preset with SRC9 outside execution.

Merge Risk: ⚪ Minimal · up to 8fcd1

This PR adds multisig account and preset functionality with associated interfaces, tests, and documentation. The remaining items are optional follow-up checks and do not present an actionable merge-blocking risk, so it is merge-ready after normal checks and review.

Poem

I’m a rabbit with keys in a neat little row,
Quorum-approved calls now hop where they go.
Signers join, leave, and update with care,
While SRC9 sends safe calls through the air.
Upgrade the class hash—then nibble a pear!

packages/presets/src/tests/test_multisig_account.cairo (1)

83-104: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add coverage for __validate_deploy__.

The preset ABI declares __validate_deploy__(class_hash, contract_address_salt, quorum, signers) at lines 25-31 of packages/presets/src/interfaces/multisig_account.cairo. That signature is the part of the deployment flow that differs from the standard account preset, and no test in this file calls it. __validate_declare__ is also uncovered.

Add a test that cheats the transaction hash and signature, then asserts __validate_deploy__ returns starknet::VALIDATED for the deployed quorum and signer set. Use the same pattern as test_execute_self_call_changes_quorum.

71-77: 🔒 Security & Privacy | 🔵 Trivial | ⚡ Quick win

Add a preset test for direct change_quorum access.

The component guards all signer-management mutators. The preset tests lack a foreign-caller test for the embedded ABI. Add one that expects 'MultisigAccount: unauthorized'.

Review — account / presets / interfaces

  • Mediumpackages/account/README.md:43-51, packages/presets/README.md:15,244fb2b73e rolled back every docs/ change, so these links now point at api/account#MultisigAccountComponent, #IMultisigAccount, #IMultisigDeployable and presets#MultisigAccountUpgradeable anchors that don't exist, and _class_hashes.adoc has no entry for the new preset → restore the .adoc pages (CONTRIBUTING makes both the docs and the class-hash update mandatory), or drop the links until they land.
  • packages/account/src/multisig_account/multisig_account.cairo:489-598 and storage_utils.cairo:10-32 — the signer registry (SignersInfo + its StorePacking, _add_signers, the swap-and-pop in _remove_signers, _replace_signer, _change_quorum, assert_only_self, the three events, most of Errors) is a near-verbatim copy of packages/governance/src/multisig/multisig.cairo:556-673 and governance/src/multisig/storage_utils.cairo:41-84 with ContractAddress swapped for felt252, so a security-critical registry now has to be fixed in two places in lockstep → extract it once, generic over the signer key type, and have both MultisigComponent and MultisigAccountComponent build on it.
  • packages/account/src/multisig_account/storage_utils.cairo:20-32 — the new packing has only two hand-picked vectors behind it, while the governance twin ships #[fuzzer] roundtrips (governance/src/multisig/storage_utils.cairo:87-110) precisely because a V1 off-by-one there survived hand-picked vectors, and packages/account/Scarb.toml:38 already declares fuzzing = [] → add the #[fuzzer] fn test_pack_unpack_signers_info(quorum: u32, signers_count: u32) roundtrip.
  • packages/account/src/tests/test_multisig_account.cairo, packages/presets/src/tests/test_multisig_account.cairo:144 — two branches uncovered: re-adding a previously removed signer (swap-and-pop leaves MultisigAccount_signers_indices[removed] = 0, so remove-then-add is the classic failure mode for this registry shape), and execute_from_outside_v2 with a sub-quorum signature — only the happy path is tested → add both.
  • packages/account/src/multisig_account/multisig_account.cairo:444-448 — the header's signer-count felt carries no information: provided_signer_count is already derived from signature.len() after the % SIGNATURE_RECORD_LENGTH check, so signature[1] can only agree or reject an otherwise well-formed signature → drop it from the encoding and let the length define the count; the version felt already gates future format changes.
  • CHANGELOG.md:14, packages/interfaces/CHANGELOG.md:14 — no PR reference, while the entry directly below carries (#1683) → append (#1745).
  • packages/presets/README.md:5-9, packages/interfaces/README.md:3-5, packages/account/README.md:5-11 — unrelated prose rewrites ride along with the feature: the presets intro loses the note that presets deliberately don't cover things like ERC20Pausable, and the interfaces heading changes from "Standardized Interfaces" to "Interface Traits" → revert those and keep only the multisig additions. Same file, 11-15: MultisigAccountUpgradeable is the only preset with a prose block above the list — move it to the docs page.
  • PR body — no Fixes #N and the PULL_REQUEST_TEMPLATE.md checklist was dropped; CONTRIBUTING asks the body to open with "Fixes Add docs for extensibility pattern #123" → add the issue link and the checklist.
