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=$(nansen trade quote --chain solana --from SOL --to USDC --amount 1000000000 2>&1 | grep "Quote ID:" | awk '{print $NF}')
nansen trade execute --quote "$quote_id"
Common Token Addresses
| Token | Chain | Address |
|---|
| SOL | Solana | So11111111111111111111111111111111111111112 |
| USDC | Solana | EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v |
| ETH | Base | 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee |
| USDC | Base | 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 |
Amounts are in base units — NEVER USD
--amount accepts integer base units only (lamports, wei, etc). It is never a USD value.
| Token | Decimals | 1 token = |
|---|
| SOL | 9 | 1000000000 |
| ETH | 18 | 1000000000000000000 |
| USDC | 6 | 1000000 |
If the user says "$20 worth of X", you must convert USD → token amount → base units. For example, to buy $20 of SOL at $150/SOL: $20 ÷ $150 = 0.1333 SOL = 133,300,000 lamports → --amount 133300000. Use a price lookup (e.g. nansen research token info) to get the current price first.
Flags
| Flag | Purpose |
|---|
--chain | solana or base |
--from | Source token (symbol or address) |
--to | Destination token (symbol or address) |
--amount | Amount in base units (integer) |
--wallet | Wallet name (default: default wallet) |
Environment Variables
| Var | Purpose |
|---|
NANSEN_WALLET_PASSWORD | Required fortrade execute. 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-manager 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.
