dexswap-quote
Non-custodial swap calldata for Base: give tokenIn, tokenOut, raw amountIn, slippage and recipient; we read Aerodrome and Uniswap V3 on-chain state, pick the max-output route, and return ready-to-sign transaction calldata plus the ERC-20 approval, amountOutMin, price impact and the venues compared. You sign with your own wallet — we never hold or move funds.
