EchoooA2A

EchoooA2A describes a payment flow in which a user’s shopping agent sends purchase intent to merchant agents, receives cart and payment requirements, and uses a wallet to verify balances and sign an on-chain payment payload. The platform describes AP2 as the authorization and trust layer and x402 as the transaction execution layer, supporting payments such as USDC and ETH on Base, Ethereum, Polygon, and other EVM-compatible chains. It emphasizes device- and wallet-level signatures, on-chain receipts, auditability, anti-replay controls, and privacy-preserving payment information.
