Execute DEX swaps on Solana or Base, including cross-chain bridges. Use when buying or selling a token, getting a swap quote, or executing a 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.
nansen trade quote \
--chain solana \
--from SOL \
--to USDC \
--amount 1000000000
Symbols resolve automatically: SOL, ETH, USDC, USDT, WETH. Raw addresses also work. Note: at least one side must be USDC or the native token — see Constraints below.
Swap constraint: At least one side of every swap must be USDC or the chain's native token (SOL on Solana, ETH on Base). Arbitrary token-to-token swaps (e.g. WETH→USDT, BONK→JUP) are rejected.

nansen trade execute --quote <quote-id>
Bridge tokens between Solana and Base using --to-chain:
nansen trade quote \
--chain base \
--to-chain solana \
--from USDC \
--to USDC \
--amount 1000000
For Solana↔Base bridges, the destination wallet address is auto-derived from your wallet (which stores both EVM and Solana keys). Override with --to-wallet <address> if needed.
Note: you need gas on the source chain to submit the initial transaction (e.g. SOL for Solana→Base, ETH for Base→Solana).
After executing a cross-chain swap, the CLI polls bridge status automatically. To check manually:
nansen trade bridge-status --tx-hash <hash> --from-chain base --to-chain solana
# 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"

By default, --amount accepts integer base units (lamports, wei, etc). Use --amount-unit token for human-readable token amounts, or --amount-unit usd to specify a USD value — the CLI resolves price and decimals automatically.
# Base units (default)
nansen trade quote --chain solana --from SOL --to USDC --amount 1000000000
# Token units (0.5 SOL = 500000000 lamports, resolved automatically)
nansen trade quote --chain solana --from SOL --to USDC --amount 0.5 --amount-unit token
# USD amount ($50 worth of SOL, price resolved via Nansen search API)
nansen trade quote --chain solana --from SOL --to USDC --amount 50 --amount-unit usd
| Token | Decimals | 1 token = |
|---|---|---|
| SOL | 9 | 1000000000 |
| ETH | 18 | 1000000000000000000 |
| USDC | 6 | 1000000 |
If the user says "$20 worth of X", use --amount-unit usd directly — no manual conversion needed. The CLI fetches the current price and converts for you.

--auto-slippage | Enable auto slippage calculation |
--max-auto-slippage | Max auto slippage when --auto-slippage is enabled |
--swap-mode | exactIn (default) or exactOut |
trade execute flags| Flag | Purpose |
|---|---|
--quote | Quote ID from trade quote |
--wallet | Wallet name (default: default wallet) |
--quote-index | Pin a specific quote by index (0-based) when multiple quotes were returned |
--no-simulate | Skip pre-broadcast simulation |
trade bridge-status flags| Flag | Purpose |

NANSEN_WALLET_PASSWORD | Required for trade execute. Wallet encryption password — persisted in ~/.nansen/.env. Source before executing: source ~/.nansen/.env && nansen trade execute ... |

Agents: Never hold a wallet password only in session memory. If
NANSEN_WALLET_PASSWORDis not in~/.nansen/.env, follow the setup flow in the nansen-wallet-manager skill Password Policy to generate and persist one before proceeding.
