EVM Wallet Tracking
Track your Ethereum, Arbitrum, and BSC wallets by pasting your address. FinCobra monitors token balances and calculates PnL from deposit and withdrawal flows after you connect.
Supported Chains
| Chain | Tokens Tracked |
|---|---|
| Ethereum | ETH + ERC-20 tokens |
| Arbitrum | ETH + ERC-20 tokens |
| BSC (BNB Chain) | BNB + BEP-20 tokens |
How to Connect
Paste your 0x wallet address — that's it. The connection is completely read-only. A wallet address can only be used to view balances and transactions on-chain.
How PnL Works
EVM wallets use the baseline PnL model:
initialValue= your portfolio's USD value at the time you add the wallet- Only deposits and withdrawals that occur after the initial snapshot are tracked
- A 90-day transaction sync window is used for flow detection
This means the adjusted PnL reflects gains and losses from the point you started tracking — not all-time.
Why Baseline Instead of Full-History?
Unlike Bitcoin xPub wallets where the full transaction history is available via the blockchain, EVM chain indexing has practical limits. The baseline approach ensures reliable PnL without depending on complete historical data.
What's Included
- Token balances across all supported chains
- Deposit/withdrawal flow tracking for adjusted PnL
- Multi-chain aggregation — all your EVM wallets contribute to your total portfolio PnL
Limitations
- PnL only tracks flows after you add the wallet
- Per-token cost basis (zero-crossing) is not available for EVM wallets
- Only the tokens with detectable balances at snapshot time or with subsequent transactions are tracked
