Complete design specification for the EVM adapter access control module with 1:1 parity to the Stellar adapter. Includes spec, plan, research, data model, API contracts, quickstart guide, requirements checklist, and dependency-ordered tasks.
…p ui-types Migrate Stellar adapter from generic indexerUri to the feature-specific accessControlIndexerUrl field on BaseNetworkConfig. Update builder app config export to prefer accessControlIndexerUrl with indexerUri fallback. Bump @openzeppelin/ui-types to ^1.7.0 across adapter-stellar, adapter-evm-core, adapter-evm, and builder. Add EVM-only HistoryChangeType mappings to Stellar indexer client (mapped to UNKNOWN). Remove temporary type augmentation files.
Update spec, quickstart, data model, and tasks to reflect accessControlIndexerUrl migration from EvmNetworkConfig to BaseNetworkConfig, Stellar adapter migration, and phase 0 completion.
Create shared infrastructure for the EVM access control module: - Directory structure mirroring Stellar adapter layout - Constants (DEFAULT_ADMIN_ROLE, ZERO_ADDRESS) - Types (EvmAccessControlContext, EvmTransactionExecutor) - ABI fragments for all OZ access control functions (22 ABIs) - Feature detection signature constants for capability analysis - T004 skipped: accessControlIndexerUrl already in ui-types@1.7.0
Add input validation for the access control module: - validateAddress: reuses existing isValidEvmAddress, throws ConfigurationInvalid with contextual paramName - validateRoleId: bytes32 hex format validation - validateRoleIds: array validation with deduplication - 41 tests covering addresses, role IDs, and error messages - Update tsconfig to include test/ for IDE resolution
…on (phase 3) Implement feature detection via ABI analysis (checking function names AND parameter types) and the EvmAccessControlService class with registerContract, addKnownRoleIds, getCapabilities, and dispose. Includes 68 tests (37 feature-detection + 31 service).
…phase 4) Implement on-chain reader (readOwnership, getAdmin via viem), EvmIndexerClient (GraphQL queries for pending transfers), and service methods (getOwnership, getAdminInfo) with indexer enrichment and graceful degradation. State mapping: owned, pending, renounced — never expired for EVM (FR-023).
…e 5) Implement role reading and enrichment for AccessControl contracts: - onchain-reader: hasRole, enumerateRoleMembers, readCurrentRoles, getRoleAdmin, getCurrentBlock - indexer-client: queryLatestGrants for grant metadata enrichment - service: getCurrentRoles (enumeration/knownRoleIds/hasRole fallback), getCurrentRolesEnriched with graceful degradation (FR-017) - Tests for all three modules covering enumeration, known role IDs, DEFAULT_ADMIN_ROLE labeling, and partial enrichment failures
…phase 7) Implement admin transfer, accept, cancel, delay change, and delay rollback for AccessControlDefaultAdminRules contracts. Actions module (actions.ts): - assembleBeginAdminTransferAction - assembleAcceptAdminTransferAction - assembleCancelAdminTransferAction - assembleChangeAdminDelayAction (uint48 parameter) - assembleRollbackAdminDelayAction Service methods (service.ts): - transferAdminRole, acceptAdminTransfer, cancelAdminTransfer, changeAdminDelay, rollbackAdminDelay - ensureHasTwoStepAdmin capability guard (FR-024) Tests: 46 new tests (15 action + 31 service) — 386 total passing.
…hase 8) Implement role management write operations for EVM AccessControl contracts: - assembleGrantRoleAction, assembleRevokeRoleAction, assembleRenounceRoleAction in actions.ts with single-function ABI fragments - grantRole(), revokeRole(), renounceRole() in service.ts with full input validation (address + bytes32 role ID) and executeTransaction delegation - renounceRole is EVM-specific (Stellar uses revokeRole for self-revocation) - 48 new tests covering action assembly and service method behavior All 428 tests pass. US4+US5+US6 complete — all P2 write operations functional.
Implement historical event queries with filtering and pagination via the indexer. Maps all 13 EVM event types to HistoryChangeType (R6). Graceful degradation returns empty result when indexer is unavailable.
…se 10) Implement exportSnapshot() combining getCurrentRoles() + getOwnership() with graceful degradation for non-Ownable contracts. Validates snapshot structure via validateSnapshot(). Adds 15 TDD tests covering all US8 acceptance scenarios, parity checks, and edge cases.
…e 11) Implement role discovery from indexer historical events (US9): - Add discoverRoleIds() to EvmIndexerClient with DiscoverRoles GraphQL query extracting unique role IDs from events - Replace discoverKnownRoleIds() stub with full implementation: caching, knownRoleIds precedence, single-attempt flag - Update attemptRoleDiscovery() to delegate to indexer discovery - Add 21 tests covering discovery, caching, graceful degradation
Wire the EVM access control module into adapter packages: - Create barrel exports in adapter-evm-core/src/access-control/index.ts - Re-export access control module from adapter-evm-core/src/index.ts - Add accessControlIndexerUrl to all mainnet and testnet network configs - Implement lazy getAccessControlService() in EvmAdapter with executeTransaction callback wrapping signAndBroadcast - Add integration test covering lazy init, service interface, full register-capabilities-ownership flow, and callback wiring
Add minor changesets for adapter-evm-core (access control module) and adapter-evm (getAccessControlService + indexer URLs). Mark Phase 13 tasks complete: test suite validation, quickstart verification, TODO review, and API parity check.
Add env-var-gated integration tests for the EVM indexer client against real SubQuery indexers on Sepolia. Tests cover connectivity, history queries with filtering/pagination, role discovery, latest grants, pending transfers, data integrity, and contract-specific verification for AccessControlMock, OwnableMock, Ownable2StepMock, and CombinedMock contracts. All tests skip gracefully when INDEXER_URL is not set.

Pull request overview
This PR adds an EVM Access Control module (in adapter-evm-core) and wires it into the EVM adapter via a lazily initialized getAccessControlService(), while also migrating Stellar + Builder to the new accessControlIndexerUrl network config field and bumping @openzeppelin/ui-types to ^1.7.0.
Changes:
- Add EVM access-control implementation (capability detection, on-chain reads, tx assembly, indexer client, and service orchestration) with extensive tests and an adapter integration test.
- Migrate Stellar adapter and Builder export logic to prefer
accessControlIndexerUrl(with fallback toindexerUri) and update network configs accordingly. - Bump
@openzeppelin/ui-typesdependencies/locks and add changesets for EVM packages.

The Stellar testnet indexer URL appears to contain a typo in the subdomain (openzepplin vs openzeppelin). If this is not an intentional endpoint, it will break history/indexer features on Stellar testnet.

This changeset claims accessControlIndexerUrl endpoints were added for networks like Gnosis, Celo, Blast, Mantle, and Mode, but the updated packages/adapter-evm/src/networks/mainnet.ts and testnet.ts in this PR only define a smaller subset of networks. Please either add the missing network configs/endpoints or adjust the release note to match what’s actually included.

getCapabilities() sets supportsHistory based only on whether an indexer URL is configured (hasIndexerEndpoint()), not whether the indexer is actually reachable. This can incorrectly report supportsHistory: true when the endpoint is down, contradicting the intended semantics. Consider awaiting this.indexerClient.isAvailable() (and optionally refreshing cached capabilities when availability changes).

hasIndexerEndpoint() only checks networkConfig.accessControlIndexerUrl. For backward compatibility and to match the documented precedence, this should also fall back to networkConfig.indexerUri (and/or the same resolution logic used by the indexer client), otherwise networks/configs that still set only indexerUri will be treated as having no indexer configured.

The indexer endpoint is resolved only from networkConfig.accessControlIndexerUrl. If callers still provide indexerUri (or you want to preserve the same precedence as the Stellar adapter), this should prefer accessControlIndexerUrl but fall back to indexerUri to avoid silently disabling history on older configs.

validateRoleIds() deduplicates using the trimmed string but does not normalize case. Since bytes32 hex strings are case-insensitive, role IDs that differ only by casing will not be deduplicated, which can cause redundant queries and inconsistent downstream behavior (e.g., DEFAULT_ADMIN_ROLE labeling). Consider normalizing to a consistent case (typically lowercase) before deduplication/return.
| return [...new Set(roleIds.map((r) => r.trim()))]; | |
| const normalizedRoleIds = roleIds.map((r) => r.trim().toLowerCase()); | |
| return [...new Set(normalizedRoleIds)]; |
…ry events Replace plain string 'OWNER' fallback with event-type-aware role resolution in transformToHistoryEntries. Ownership events now use DEFAULT_ADMIN_ROLE (bytes32 zero) with label 'OWNER', admin events use DEFAULT_ADMIN_ROLE with label 'DEFAULT_ADMIN_ROLE', ensuring role.id is always a valid bytes32 hex string in the EVM context.
validateRoleId trimmed whitespace internally but returned void, causing callers (grantRole, revokeRole, renounceRole) to pass untrimmed role IDs to transaction assembly. Now returns the trimmed string, consistent with validateRoleIds.
queryLatestGrants keyed the grant map by account address only, causing cross-role metadata contamination when an account holds multiple roles. Switch to a composite role:account key via the new grantMapKey() helper and update getCurrentRolesEnriched to use the same composite lookup.

Consolidate three independent createPublicClient call sites into a single createEvmPublicClient utility in utils/public-client.ts.
