An agent bridges USDC from Arc to Base. One signature.

The agent asks Liquid Agent x402 to move $1, gets a 402 with the exact price, signs one USDC payment on Arc, and our contract burns it through Circle CCTP. Exactly $1 lands on Base at the agent's own address. No account, no API key, no gas token.

Arc contract 0x3bc7…77b1 paid in USDC on Arc fee capped on-chain at max(3%, $0.05) built on Circle CCTP v2
