Track Your Bitcoin Cold Wallet

How do I track a Bitcoin cold wallet?

1. On your hardware or cold wallet, copy a receiving address that holds your coins. Reading it from the device's screen, a QR code or your own notes is enough; the device does not need to be connected to your phone.
2. In BTC Mate, add the address by pasting or scanning it and give it a label such as "Vault" or "Savings". Repeat for each address that holds coins.
3. BTC Mate loads the public balance and history, values it in your currency and shows estimated entry price, estimated profit or loss and performance over time.

From then on the Overview shows all tracked addresses, and the Insights tab shows a performance chart and per-address analysis. This is the portfolio view your cold wallet never had: the exchange-style profit and loss line, applied to coins you hold yourself. How the performance estimate works.

Can I track a hardware wallet without connecting it?

Yes. Every hardware wallet has public addresses; they are what you share to receive Bitcoin. A public address reveals the balance and transaction history recorded on the blockchain and nothing more; it cannot be used to spend. So you can hand a public address to a tracking app and get a current overview while the keys stay cold. BTC Mate never talks to the device, does not pair with it and does not use its companion software.

Can I monitor Bitcoin stored with a hardware wallet using a public address?

That is the entire mechanism. The blockchain does not know or care which device generated an address. Once you add the address, BTC Mate retrieves the same public data a block explorer would show, then adds what an explorer does not: value in your currency, history over time, estimated entry price and profit or loss, and a combined view across addresses. Modern wallets generate a new receiving address for each incoming payment, so add each address that holds coins to see the whole holding.

Can BTC Mate be used with an address generated by Ledger?

Yes, in the sense that matters: an address generated by a Ledger device is an ordinary Bitcoin address, and BTC Mate can track it once you enter it. There is no integration with the device, no pairing and no partnership with Ledger; BTC Mate simply reads public blockchain data for the address. Ledger is a trademark of its owner.

Can BTC Mate be used with an address generated by Trezor?

Yes, in exactly the same way. Copy a receiving address from your Trezor and add it to BTC Mate. The app does not connect to the device or use Trezor software, and there is no partnership. The same applies to Coldcard, BitBox, Jade, Keystone, paper wallets and any other wallet that gives you a public address. Trezor is a trademark of its owner.

Is it safe to share a Bitcoin public address?

Sharing a public address does not give anyone control over the funds. Spending requires a signature from the private key, which never leaves your cold wallet. What a public address does reveal is financial activity: the balance and the transaction history of that address. That has privacy implications, so share addresses deliberately. Tracking an address in BTC Mate means the app sends that public address to a blockchain data provider to fetch its history; the provider could in principle associate your IP address with it. The Privacy Policy spells this out. Addresses you add are stored on your iPhone, not on a BTC Mate server. Public address vs. private key, explained.

What information does a public Bitcoin address reveal?

• The current balance of the address.
• Every transaction that sent Bitcoin to it or spent from it, with amounts, timestamps and confirmations.
• The other addresses involved in those transactions.
• The fees paid by transactions spending from it.

It does not reveal the owner, the private key, or the price paid. Any performance figure therefore combines this public history with historical market prices and is an estimate, which is how BTC Mate labels it.

Cold wallet tracker vs. Bitcoin wallet

The two are complementary. You keep using your wallet for anything that moves Bitcoin; BTC Mate is the read-only companion for watching how it develops. If an app claiming to "track" your cold wallet asks for a seed phrase, close it.
