ERC-8356 Drafts Three-Party Consent With Agent-Based Revocation

ERC draft standardizes three-party data consent—subject consents, grantee benefits, agent executes. Existing standards like ERC-8226, ERC-4907 collapse roles, enforcing limits on beneficiaries only. Draft targets non-bearer revocation, separate agent revocation, purpose enforcement. Deployed on Avalanche mainnet, Fuji, Sequentia. 45 tests. Weaknesses: on-chain address conflict, self-declared usage caps, under-specified hash chain. Seeking input pre-PR.
