Trade on Base

Swap on Base from your agent

MoltNode reads Base. Chord, from the same makers, finds the best route across Base's DEXs and returns an unsigned transaction your agent signs with its own key, then broadcasts through this endpoint. One call quotes 10 USDC into ETH with the transaction and a simulation.
