A watch-only wallet tracks balances and builds transactions from public keys only, so it can never spend by itself. Learn its uses and privacy cautions.
See everything, sign nothing
A watch-only wallet is loaded with public information, an xpub or a descriptor, instead of private keys. It can:
- show balances and history,
- generate new receiving addresses,
- build unsigned transactions for a hardware wallet to sign.
It cannot spend on its own.
Uses
- The online half of cold storage.
- Checking savings on your phone without putting keys on it.
- Accountants, auditors or family members monitoring a wallet.
- Point-of-sale systems creating fresh addresses for each payment.
Privacy caution
Whoever has the xpub sees every address and balance in that account. Load it only into software and services you trust, ideally connected to your own node.
Watch addresses on MyBitcoinExplorer
Create a free account, open the dashboard and add addresses to a watchlist with private labels. Connect Telegram in settings if you want a message when a watched address receives or spends. No keys are ever involved.
Watch-only for families
Giving a family member watch-only access lets them confirm savings exist, for example for inheritance planning, without any ability to move them.
Key takeaways
- Watch-only wallets use public keys, so they can't spend.
- They pair with hardware wallets to sign offline.
- An xpub reveals the whole account, so share it carefully.

Is a watch-only wallet safe if my phone is stolen?
The thief can't spend, but can see your balances and history.
Can I watch a single address?
Yes, many wallets and explorers let you watch individual addresses.
Can a watch-only wallet send bitcoin?
It can prepare a transaction, but a device with the private keys must sign it.
Is watching an address private?
The service you use learns which addresses you watch, so choose one you trust.
