Crypto Portfolio Tracker
FinCobra's watchlist tracks your crypto portfolio across wallets and exchanges in a single dashboard. All connections are read-only — we never have access to your funds.
Supported Sources
| Source | Connection | PnL Model |
|---|---|---|
| Bitcoin xPub | Export xpub from hardware wallet | Full-history (all-time PnL) |
| Binance | Read-only API key | Flow-based + per-token zero-crossing |
| EVM Wallets | Paste 0x address | Baseline (post-snapshot flows) |
| Solana | Paste Solana address | Baseline (post-snapshot flows) |
| Bybit | Read-only API key | Flow-based (header-level) |
| Hyperliquid | Wallet address | Flow-based (header-level) |
How Tracking Works
When you add a source, FinCobra takes an initial snapshot of your balances and begins syncing transactions. The system tracks deposits, withdrawals, and trades over time to calculate your PnL.
Each account has a pnlReady flag — PnL numbers only appear once the system has enough transaction history to produce meaningful results. Until then, you see balances without PnL.
PnL at a Glance
FinCobra calculates PnL at two levels:
- Account-level (adjusted PnL) — how much your account has gained or lost after accounting for deposits and withdrawals. Available for all sources.
- Per-token PnL — cost basis and profit/loss for each individual token using a zero-crossing algorithm. Currently available for Binance.
See How PnL Works for the full formulas and a worked example.
