Setup

npm install -g nansen-cli

Auth (pick one)

x402 Pay-Per-Call (no API key needed):

nansen wallet create    # Generates EVM + Solana keypair
# Fund the EVM address with USDC on Base (~$0.50 minimum)
export NANSEN_WALLET_PASSWORD="your-password"  # Skip interactive prompt
# Done — CLI auto-pays $0.01-$0.05 per call

API Key:

export NANSEN_API_KEY=your-api-key
# Or: nansen login --api-key YOUR_KEY

Token Analytics

--chain required. Use --token for the token address.

nansen research token screener --chain solana --timeframe 24h --smart-money --limit 20
nansen research token info --token <addr> --chain solana
nansen research token indicators --token <addr> --chain solana
nansen research token ohlcv --token <addr> --chain solana --timeframe 1h --limit 24
nansen research token holders --token <addr> --chain solana --smart-money
nansen research token flows --token <addr> --chain solana --days 7
nansen research token flow-intelligence --token <addr> --chain solana
nansen research token who-bought-sold --token <addr> --chain solana
nansen research token dex-trades --token <addr> --chain solana --limit 20
nansen research token pnl --token <addr> --chain solana --sort total_pnl_usd:desc
nansen research token transfers --token <addr> --chain solana --enrich
nansen research token jup-dca --token <addr>                  # no --chain
nansen research token perp-trades --symbol ETH --days 7       # no --chain, uses --symbol
nansen research token perp-positions --symbol BTC              # no --chain
nansen research token perp-pnl-leaderboard --symbol SOL        # no --chain

Native tokens (SOL, ETH) are not supported on most token endpoints — use specific token addresses.

Wallet Profiler

--chain and --address required for most commands.

nansen research profiler balance --address <addr> --chain solana
nansen research profiler labels --address <addr> --chain ethereum
nansen research profiler pnl --address <addr> --chain ethereum --days 30
nansen research profiler pnl-summary --address <addr> --chain ethereum
nansen research profiler transactions --address <addr> --chain ethereum --limit 20
nansen research profiler historical-balances --address <addr> --chain solana --days 30
nansen research profiler related-wallets --address <addr> --chain ethereum
nansen research profiler counterparties --address <addr> --chain ethereum
nansen research profiler perp-positions --address <addr>       # no --chain
nansen research profiler perp-trades --address <addr>          # no --chain
nansen research profiler search --query "Vitalik"              # no --chain
nansen research profiler batch --addresses "0xabc,0xdef" --chain ethereum --include labels,balance,pnl
nansen research profiler trace --address <addr> --chain ethereum --depth 2 --width 10  # ⚠️ makes N×width API calls
nansen research profiler compare --addresses "0xabc,0xdef" --chain ethereum

Search

nansen research search "jupiter" --type token
nansen research search "Vitalik" --type entity --limit 5
nansen research search "0xd8dA..."                             # by address

Perps (Hyperliquid)

nansen research perp screener --sort volume_usd:desc --limit 20
nansen research perp leaderboard --days 7 --limit 20

Portfolio

nansen research portfolio defi --wallet <addr>
nansen research points leaderboard --tier green --limit 20

Trading

Two-step: quote then execute.

# Get quotes from multiple aggregators (Jupiter, OKX, LiFi)
nansen trade quote --chain solana \
  --from <from_token_address> \
  --to <to_token_address> \
  --amount <base_units>

# Execute the best quote
nansen trade execute --quote <quote-id>

# Trade via WalletConnect (hardware wallets, mobile wallets — EVM only)
nansen trade quote --chain base --from <addr> --to <addr> --amount <base_units> --wallet walletconnect
nansen trade execute --quote <quote-id> --wallet wc

⚠️ Always inspect the quote response (price, slippage, expiry) before executing. Quotes expire — if you wait too long, execute will fail. Get a fresh quote and retry. Trades are irreversible once executed on-chain.

⚠️ Amounts are in base units (not human-readable):

Symbol shortcuts (SOL, ETH) don't work yet — use full addresses.

Common Addresses

Solana: SOL So11111111111111111111111111111111111111112 · USDC EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v · JUP JUPyiwrYJFskUPiHa7hkeR8VUtAeFoSYbKedZNsDvCN

Base: ETH 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee · USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 · DEGEN 0x4ed4e862860bed51a9570b96d89af5e1b0efefed

Wallet Management

nansen wallet create          # Create EVM + Solana keypair
nansen wallet list            # List wallets
nansen wallet send --to <addr> --amount 1.5 --chain evm    # Send native
nansen wallet send --to <addr> --chain evm --max            # Send entire balance

# Send via WalletConnect (EVM only)
nansen wallet send --to <addr> --amount 1.5 --chain base --wallet walletconnect

Use --wallet walletconnect (or --wallet wc) to sign trades and transfers via a WalletConnect-connected wallet (hardware wallets, mobile wallets) instead of local keys. EVM chains only.

Common Options

Schema Introspection

Stuck? Run nansen schema or nansen schema <command> to discover all available commands, options, and return fields.

nansen schema                 # Full JSON schema — all commands, options, return fields

Trading & x402: solana, base

Gotchas

• Native tokens (SOL, ETH) don't work on most token endpoints — use wrapped addresses
• Perp commands don't take --chain (Hyperliquid only)
• --amount is always in base units, not human-readable
• Profiler trace makes N×width API calls — can burn credits fast
• x402 auth needs USDC on Base, not Solana
