EVM Wallet Tracking ​

Track your Ethereum, Arbitrum, and BSC wallets by pasting your address. FinCobra monitors token balances and calculates unrealized PnL from known acquisition costs and matched transfers.

Supported Chains ​

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 ​

Supported tokens use weighted-average acquisition cost. A matched transfer between connected accounts carries that cost to its destination. Current holdings with known cost contribute to unrealized PnL.

External receipts without a matched source use historical market value at entry to the tracked portfolio. Token identity must match a supported contract; a matching symbol alone is insufficient.

See How PnL Works for the calculation and data requirements.

Coverage ​

Indexing limits can leave history incomplete. Failed or partial balance reads do not count as sales. PnL is unavailable when current quantities cannot be reconciled with the accounting history.
