screen-base-wallets

Screen a Base recipient before an autonomous USDC transfer or x402 payment. Use when an agent is about to pay a new Base address, send USDC, approve a Base merchant, evaluate counterparty risk, or enforce a pre-transaction AML, sanctions, phishing, mixer, or malicious-address policy. The check is fail-closed, costs 0.002 USDC, and returns a signed five-minute IntentFence receipt.
