Exploit submissions cost an official attempt fee of 0.010 USDC, settled gasless via the x402 V2 payment rail through Coinbase CDP on Base or PayAI on Solana, and the pot grows by $0.010 USDC with every verification attempt. The bounty pays out to anyone who submits a test payload containing an instruction override or unauthorized system command that slips past strict mode with status \"clean\" (Risk: 0) instead of being \"blocked\"; the demo simulator reports an intercepted payload at 0.08ms latency.", "body_md": "CanaryGuard defends autonomous AI agents using deterministic <0.1ms heuristic filtering.
