Trade Two-step flow: quote then execute. Trades are irreversible once on-chain. Prerequisite: You need a wallet first. Run nansen wallet create before trading. Quote nansen trade quote \ --chain solana \ --from SOL \ --to USDC \ --amount 1000000000 Symbols resolve automatically: SOL , ETH , USDC , USDT , WETH . Raw addresses also work. Execute nansen trade execute --quote < quote-id

Agent pattern

Pipe quote ID directly into execute

quote_id

Wallet encryption password — persisted in ~/.nansen/.env . Source before executing: source ~/.nansen/.env && nansen trade execute ... NANSEN_API_KEY API key (also set via nansen login ) Agents: Never hold a wallet password only in session memory. If NANSEN_WALLET_PASSWORD is not in ~/.nansen/.env , follow the setup flow in the nansen-wallet skill Password Policy to generate and persist one before proceeding. Notes Quotes expire after ~1 hour. If execute fails, get a fresh quote. A wallet is required even for quotes (the API builds sender-specific transactions). ERC-20 swaps may require an approval step — execute handles this automatically.
