x402 proves payment; this answers whether the wallet should be recognised. Resolves a wallet's onchain identity — Coinbase verification (a KYC'd attestation), Basename, and an ERC-8004 registry entry when configured — and corroborates with its payment track record. One verdict: recognised / named / anonymous / unknown. The identity leg alongside x402-seller-check (endpoint) and agent-reputation (behaviour). Identity is not intent; a degraded read is 'unknown'. Not financial advice.
