Two live agent payment runs with SRA-RiskGate today, plus a day of real x402 data. Circle Gateway on Arc testnet: one agent task, three proposed payments. One approved, accepted by Gateway and settled to the payee. An unlimited approval was held and a look-alike payee was rejected, neither signed. Base Sepolia: 0.01 USDC to the known payee approved, sent and verified from the receipt. 2.00 USDC to an unknown payee held before signing. Log: https://gist.github.com/sriram1983007-dev/35eab0e934a512346193bcdb5b12d9cf Real traffic: 1,500 x402 settlements sampled across 24 hours on Base mainnet. Median signature had under 5 minutes left at settlement, but 23 were still usable for 8 to 41 days, one for 273.75 USDC. Model: https://huggingface.co/sriram1983007/SRA-RiskGate-4B

🛡️ AI agents now pay with USDC through Circle and Coinbase AgentKit, and those payments are final. SRA-RiskGate checks the exact bytes before the agent signs. If this is useful for your agent, a ❤️ like on this https://huggingface.co/sriram1983007/SRA-RiskGate-4B page helps others find it. • Circle Wallets: `guard_circle_wallets()` wraps Circle's SDK. On Arc Testnet, a USDC payment went through, while an unlimited approve, an unknown payee and an unlimited permit never reached Circle. • Circle Gateway: batched x402 payments checked with their own 3–8 day window. A look-alike GatewayWallet and a 30-day signature were held. • Coinbase AgentKit: one action provider as the agent's only way to pay, with OFAC, limits and depeg checks before USDC moves on Base. • Also: EIP-7702 delegations, address-poisoning look-alikes, long-lived x402 signatures, self-vouching payment text. Backed by SRA-RiskGate-4B (unsafe approvals 34.6% → 0.47% on a 20k-case benchmark). `pip install "sra-riskgate[circle,agentkit]"` Model: https://huggingface.co/sriram1983007/SRA-RiskGate-4B Code: https://github.com/sriram1983007-dev/sra-riskgate Video: https://www.youtube.com/shorts/3OAEJKTi32s
