"description": "Swap stablecoins against a live non-custodial liquidity position and receive the result on-chain. Give a strategy hash and an input amount; get back an unsigned transaction that settles the swap against that maker position. Use this when an agent needs to move USDC/USDT and prefers a real on-chain counterparty to a custodial venue: the swap is simulated first, and if it cannot succeed no transaction is returned at all, so a wallet is never handed one that is certain to revert.",
