Bitcoin wallet tracker by xpub, without exposing your addresses
Track your Bitcoin wallets by their account public key (xpub, ypub, zpub): balances and transactions read by your browser, encrypted, never seen by our server.
CentraFIN tracks your Bitcoin wallets from their account public key (xpub, ypub, or zpub), and protects them better than tracking by address: your browser derives your addresses, reads their balances, and encrypts it all. CentraFIN's server never sees an address, a public key, or a balance.
What CentraFIN reads
- Balances: of every address derived from your public key, receiving and change addresses alike.
- Transactions: incoming and outgoing, matched with your platforms when you send to one of them.
- New addresses: picked up automatically as your wallet starts using them.
Find your account's public key
- Sparrow: the Settings tab, the keystore's public key field.
- Electrum: Wallet › Information, Master Public Key.
- Ledger Live: the account, then Edit account › Advanced.
- Trezor Suite: the account, then Details › Show public key.
The key starts with xpub, ypub, or zpub. It lets you see balances, never spend. Never give out your recovery phrase: CentraFIN doesn't ask for it and rejects any private key.
Add it to CentraFIN
- Open Connectors, the Private wallets section, then Add a wallet.
- Give it a name and paste the public key of each account.
- Your browser starts reading; the balances come in within a few seconds.
Your privacy
- Encrypted vault: your wallets live in a vault that your browser seals (AES-256-GCM), unlocked by your passkey when you sign in.
- Read by your browser: balances come from public Bitcoin nodes, over an end-to-end encrypted connection that goes through a blind relay. The server reads nothing of what passes through it.
- Spread-out addresses: each address is always read from the same randomly drawn node, so no single node sees your whole wallet.
With your other accounts
Your self-custodied bitcoin joins your Kraken, Coinbase, OKX, Binance, Hyperliquid, and Interactive Brokers accounts. A withdrawal from a platform to your wallet is recognized as an internal transfer.

Frequently asked questions
Why a public key rather than addresses?
A modern wallet uses a new address every time it receives a payment. The account's public key lets CentraFIN find them all, without missing any.
Can the server see my addresses?
No. They are derived, read, and encrypted in your browser. The server only keeps an encrypted vault that it can't open.
Is Bitcoin wallet tracking free?
Yes, like every integration.
