v0.7.0

What's Changed

• Add Robinhood Chain (4663) deploy configuration: Robinhood RPC endpoint and Etherscan verifier settings in foundry.toml and the matching .env.example entry. The canonical ToolRegistry and predicate CREATE2 addresses are identical on Robinhood.
• Document Robinhood Chain (4663) in the deployed-address tables in the README.
• Add an explicit Etherscan v2 url to the monad entry in foundry.toml so forge script --verify config resolution no longer aborts for chain 143.

v0.6.0

What's Changed

• Add Monad (chain 143) deploy configuration: Monad RPC endpoint and verifier settings in foundry.toml and the matching .env.example entry. The canonical ToolRegistry and predicate CREATE2 addresses are identical on Monad. (#476)
• Document Monad (143) in the deployed-address tables in the README. (#477)

Full Changelog: ProjectOpenSea/opensea-devtools@tool-registry-v0.5.0...tool-registry-v0.6.0

v0.5.0

What's Changed

• feat: add ERC20BalancePredicate for ERC-20 token-balance-gated tool access (standalone example contract, deploy script, new ERC20Balance requirement type, and full test coverage)
• chore: set the canonical ERC20BalancePredicate address (0x1a834FC48B5f6e119c62C12a98b32137bCFA77cD) on Ethereum mainnet and Base
• feat: deploy ToolRegistry + all five canonical predicates to Shape (chain 360) and Abstract (chain 2741) via deterministic CREATE2, at addresses identical to the existing Ethereum mainnet and Base deployments

Full Changelog: ProjectOpenSea/opensea-devtools@tool-registry-v0.4.0...tool-registry-v0.5.0

v0.4.0

What's Changed

• Add TraitGatedPredicate contract for ERC-7496 dynamic trait gating. It combines ERC-721 ownership with an on-chain trait value match, supports a separate traits contract (e.g. a renderer), and allows a configurable trait key with up to 32 allowed values per tool. The predicate ships in script/Deploy.s.sol and a standalone script/DeployTraitGatedPredicate.s.sol, and is deployed deterministically via the Arachnid CREATE2 factory at the canonical address 0x10abF07CfA34Bf22372C57f27e8bd9C2DCF93fA1 on Ethereum mainnet and Base.

v0.3.0

What's Changed

Minor

Canonicalize SubscriptionPredicate v0.2 on Ethereum mainnet and Base. The predicate now ships in script/Deploy.s.sol at the deterministic CREATE2 address 0xCBe0cd9B1d99d95Baa9c58f2767246C52e461f25 (identical on chain 1 and 8453, deployed via the Arachnid factory with salt bytes32(uint256(1)) and the v0.2 registry as constructor arg).

Verified onchain — name() returns "SubscriptionPredicate", registry() returns 0x265BB2DBFC0A8165C9A1941Eb1372F349baD2cf1. Verified on Etherscan and Basescan.

Full Changelog: ProjectOpenSea/opensea-devtools@tool-registry-v0.2.0...tool-registry-v0.3.0

v0.2.0

What's Changed

Canonical v0.2 deployment on Ethereum mainnet + Base. ToolRegistry.version() now returns "0.2" and the registry validates predicates against IAccessPredicate interfaceId 0xbdf9dc18 (hasAccess + name + getRequirements).

New canonical addresses (chain 1 + chain 8453)

Contract	Address
ToolRegistry v0.2	0x265BB2DBFC0A8165C9A1941Eb1372F349baD2cf1
ERC721OwnerPredicate v0.2	0xc8721c9A776958FfFfEb602DA1b708bf1D318379
ERC1155OwnerPredicate v0.2	0x77373Dc3c1AE9A1e937eF3e5E08F4807D47c7c11

Same deterministic CREATE2 address on both chains.

Pre-beta breaking change

The earlier v0.1 Base deployment (0x7291...4856 registry + 0x4eC9... ERC721 predicate) is no longer canonical. Tools registered there must be re-registered against the v0.2 registry.

v0.1.2

What's Changed

Documentation-only patch release. ~7% reduction in ERC-draft length (104 net lines off) with no normative rules changed.

• Folded Manifest Hex-Field Casing subsection into Canonical Manifest Bytes (#259). The standalone subsection's per-field grammar table duplicated regexes already inline in each field's row in §2/§4/§5. Six cross-references repointed.
• Trimmed Appendix A semantic-input duplication (#259). Free-Tool / Paid-Tool semantic-input JSON blocks were byte-identical to the §2 examples; replaced with anchor-pointers. Pinned manifestHash test vectors still verify.
• Collapsed Verifiability Trust Model overlap with §5 (#259). Trust-spectrum bullets restated §5 verbatim; replaced with a single intro paragraph that cross-references §5. Kept the unique normative content (network egress under TEE, attestation freshness/revocation, MUST-NOT-grant-elevated-trust, MUST-distinguish-verified-vs-unverified).
• Merged Registry Self-Reference and Predicate Selector Collision into Predicate Validation at Registration (#259). The two sections cross-referenced each other and shared the selector-collision motivation; one merged section is clearer.
• Trimmed hasAccess docstring (#259). Replaced the inline restatement of strict ABI-bool decode rules with a single cross-reference to tryHasAccess (the canonical place for them).

No Solidity changes, no ABI changes, no deployment changes.

v0.1.1

What's Changed

Documentation-only patch release rolling up three ERC-draft clarification PRs. No Solidity, ABI, or deployment changes.

• Close logic gaps in the ERC draft (#255). Restated ToolNotFound / ToolIsDeregistered reverts in each function's docstring; reconciled setAccessPredicate MUST-validate with the idempotent no-op carve-out; made the verifiability tier consistency check bidirectional; extended the 256-byte name() cap to version(); renumbered Access (§4) and Verifiability (§5), bumping Origin-Binding to §6, Creator Binding to §7, Manifest Hash Commitment to §8, ERC-165 Support to §9.
• Second-pass logic fixes (#256). Tightened manifest hex-field casing to strict lowercase across creatorAddress, access[].kind/data, attestation.enclaveHash, and reproducibleBuild.buildHash for JCS-byte determinism, with uppercase hex listed as a verification failure. Mirrored onchain getRequirements caps (256 entries, 4,096-byte hex-decoded data, 256-byte label) into the manifest parser. Restricted access[].links values to HTTPS URLs. Fixed a MUST NOT inversion in the tryHasAccess docstring.
• Cap-feasibility note (#257). Clarified that the per-axis caps in Manifest Parser Hardening don't jointly compose under the 1 MiB ceiling.
