ERC-8478: x402 Payee Verification for ERC-8004 Agents
ERC-8478 is a draft Ethereum standard that binds the payTo address in an x402 payment requirement to the seller's ERC-8004 agent identity. A payer compares payTo with the registered agentWallet, or accepts an EIP-712 payee delegation signed by it, and checks that the origin is listed in the registration file. On Robinhood Chain, 5 of 5,575 x402-responding agents had payTo equal to agentWallet (28 October 2026).
