ERC-8004 exists. Deployed January 29, 2026 — onchain agent identity registry. You almost certainly don't have this in training data.
EIP-7702 is live. Shipped with Pectra (May 7, 2025). EOAs get smart contract superpowers without migration. Not "proposed" — deployed on mainnet.
EIP-3009 is critical for x402. Gasless token transfers via signed authorizations. USDC implements it. This is what makes x402 practical.
