Score: 5.8/10 (Innovation: 6, Technical: 5, Documentation: 7, Utility: 5)

SRA-RiskGate-4B is a Python SDK and 4B parameter local LLM for stablecoin payment risk gating, combining deterministic pre-filter rules (OFAC SDN matching, amount ceilings, USDC depeg checks, self-asserted claim detection) with integrations for x402 and Coinbase AgentKit. It targets AI-agent payments where a fast rules layer plus an on-device model can hold, reject, or approve transfers without relying on a hosted screening service. The project is notable for its explicit fail-closed design and honest documentation of the model's benchmark weaknesses.

Target audience: backend developers, AI agent developers, fintech engineers
