Trade on Avalanche

Swap on Avalanche from your agent

MoltNode reads Avalanche. Chord, from the same makers, finds the best route across Avalanche'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 AVAX with the transaction and a simulation.
