Nansen Profiler

Nansen Profiler — Wallet Intelligence

Profile any wallet: balances, labels, PnL, transactions, and counterparties.

When This Skill Activates

• "Who is this wallet?" / "What does 0x... hold?"
• "Show PnL for this address"
• "Transaction history" / "Related wallets" / "Counterparties"
• "Search for entity" / "Find wallet by name"

Command Routing

⚠️ Known Issues

• `profiler pnl` — The CLI calls the old endpoint path (pnl-and-trade-performance) which returns 404. The correct API endpoint /api/v1/profiler/address/pnl works via curl. Requires date range. Use profiler pnl-summary for aggregate PnL, or curl for per-token PnL.
• `profiler trace` (counterparty trace) — Will not work for high-volume addresses if you search longer timeframes. Use --depth 2 and short timeframes for large wallets.
• `profiler transactions` requires --date '{"from": "YYYY-MM-DD", "to": "YYYY-MM-DD"}' — the --days option alone does NOT work.

Response Field Notes

• `profiler labels` returns: label, category, definition, fullname, smEarnedDate (not label_type/label_subtype as schema suggests)
• `profiler historical-balances` returns: block_timestamp, chain, token_address, token_amount, token_symbol, value_usd (not date/balance/balance_usd)
• `profiler pnl-summary` returns top-level fields: top5_tokens, traded_token_count, traded_times, realized_pnl_usd, realized_pnl_percent, win_rate

Examples

# Search for an entity by name
nansen profiler search --query "Vitalik"
nansen profiler search --query "Binance"

# Who is this wallet?
nansen profiler labels --address 0x... --table
nansen profiler balance --address 0x... --sort value_usd:desc --limit 20 --table

# Historical balances
nansen profiler historical-balances --address 0x... --chain ethereum --days 30 --table

# Counterparties
nansen profiler counterparties --address 0x... --chain ethereum --table

# Related wallets
nansen profiler related-wallets --address 0x... --chain ethereum --limit 10 --table

# PnL summary
nansen profiler pnl-summary --address 0x... --chain ethereum --days 30

# Transactions (--date is required!)
nansen profiler transactions --address 0x... --chain ethereum --date '{"from": "2026-01-01", "to": "2026-02-15"}' --limit 20 --table

# Perp positions
nansen profiler perp-positions --address 0x...

# Batch profile multiple wallets
nansen profiler batch --addresses "0xabc...,0xdef..." --chain ethereum --include labels,balance

# Counterparty trace (BFS) — use low depth for high-volume wallets
nansen profiler trace --address 0x... --chain ethereum --depth 2 --width 10

# Per-token PnL (CLI broken, use curl)
curl -s -X POST 'https://api.nansen.ai/api/v1/profiler/address/pnl' \
  -H "apiKey: $NANSEN_API_KEY" -H 'Content-Type: application/json' \
  -d '{"address":"0x...","chain":"ethereum","date":{"from":"2026-01-01","to":"2026-02-17"}}'

# Compare two wallets
nansen profiler compare --addresses "0xabc...,0xdef..." --chain ethereum

Investigation Workflow

1. Search → find entity 2. Labels → identity 3. Balance → current holdings 4. Historical Balances → trends 5. Counterparties → interactions 6. Trace → network mapping

Ticker Resolution

If user gives a ticker instead of address:

nansen token screener --chain solana --sort volume:desc
# Filter output by token_symbol to find the address
# Note: --search flag does NOT filter results
