Third-party SDK support for a proposed wallet-state interface
ERC-8257 (Agent Tool Registry) defines an open requirement-kind namespace for gating agent tool access. A wallet-state attestation requirement kind proposed in the ERC's review process is now supported in OpenSea's official SDK: cross-chain wallet state, evaluated off-chain, signed, and verified on-chain via the RIP-7212 P-256 precompile.
Reflected in draft specs
Draft ERCs revised or extended following review contributions
- ERC-8291 (SIWE-gated NFT media, August 2026): two draft revisions followed review. The binding grammar now includes first-class syntax for entitlements beyond a single NFT, naming attestations and balance thresholds, plus ERC-20 threshold and ERC-1155 minimum-quantity forms.
- ERC-8210 (Agent Assurance, April 2026): the draft's v2 changelog credits review input on two items, the pre-commitment facts gap and the risk-hook resolution path.
- ERC-8240 (Trust Infrastructure, April to July 2026): the draft adopted methodology-scoped context hashing after a clarifying review exchange, separating per-methodology context from per-call condition identity.
- ERC-8273 (Attestation-Gated Agentic Actions, June 2026): the author accepted and extended a storage-proof-as-evidence design from review, using EIP-1186 proofs so a signed verdict can be rechecked against chain state.
In the merge path
Authored proposals in active protocol review
- UCP pull request 415 (opened May 2026): proposes wallet attestation as an identity-linking mechanism alongside OAuth. A typed provider, JWKS-based offline verification, signed booleans.
- A2A trust signals (opened March 2026): the consolidated five-signal taxonomy for agent trust originates in our authored proposal, including the on-chain credentials and on-chain activity signal types with shared JWKS verification.
- ERC-8183 (agentic commerce hooks): a wallet-state hook implementation (April 2026) in the project's review queue, alongside day-one maintenance of the companion case library.
- x402 (machine payments): co-authored cold-start trust work (February 2026) covering on-chain credential and activity signals, plus an authored extension proposal for self-scaling conditions (June 2026) and signer-authentication proposals.

On the public record
Regulatory submissions
Written comments and input to regulators, each linked to the copy the regulator itself published. Each letter states our commercial interest. Filing a comment means it was received; it does not mean a regulator agreed.
- SEC, File No. S7-2026-27 (proposed Regulation Crypto Assets, September 25, 2026): asks the Commission to confirm that an issuer may rely on a professional's confirmation of accredited status, including one tied to the purchaser's wallet and checked at the time of sale. All comments on the file.
- SEC Crypto Task Force, written input (September 25, 2026): what a relying party's record should show when it accepts a proof in place of collected data: made when eligibility matters, limited to the decision, and verifiable for as long as it must be kept. All written input.
- SEC, File No. 4-927 (Tokenized Securities Venue exemption, September 17, 2026): proposes that a venue's access check be made when access is used and leave a signed, independently verifiable record. All comments on the file.
- NIST NCCoE, AI agent identity and authorization (March 12, 2026): comments on the concept paper for the Software and AI Agent Identity and Authorization project. NIST has not published the comments it received, so the link is our own account of the submission.
The honest ceiling: no released core specification has ratified wallet-state attestation as normative. What exists today is shipped third-party tooling, draft texts revised through review, authored proposals in merge paths, and filed IETF Internet-Drafts. This page will say so plainly when that changes.
The primitive is the same everywhere it appears:
read wallet state, evaluate conditions, return a signed boolean.
