# Watch-only wallets: seeing funds without the spending keys A watch-only Bitcoin wallet tracks scripts or public derivation information without holding the private keys needed to spend the corresponding outputs. It can display transactions and help construct unsigned payments, but another signer must provide authorization. A visible balance is not proof that its viewer controls the coins.

([Output Script Descriptors General Operation](https://raw.githubusercontent.com/bitcoin/bips/927b6de9915c9262615a6399de51b200f81e5aa4/bip-0380.mediawiki); [importdescriptors RPC](https://bitcoincore.org/en/doc/29.0.0/rpc/wallet/importdescriptors/)) - **Signing:** A partially signed transaction can be passed to a separate signer. ([Partially Signed Bitcoin Transaction Format](https://raw.githubusercontent.com/bitcoin/bips/927b6de9915c9262615a6399de51b200f81e5aa4/bip-0174.mediawiki)) - **Coverage:** Imported paths, ranges and scan timestamps affect what a wallet discovers. ([importdescriptors RPC](https://bitcoincore.org/en/doc/29.0.0/rpc/wallet/importdescriptors/)) ## Separate observation from authorization A laptop can monitor an account while a separate signing device holds its secret keys. The laptop prepares transaction information; the signer checks the actual destinations and fee before returning signatures. Compromise of the laptop can still affect what is displayed or proposed. Keeping keys elsewhere does not remove the need to inspect the transaction on a trusted signing interface.

A range or timestamp that omits earlier activity can produce an incomplete view. A newly imported watcher may need to scan relevant historical blocks. Check the intended network, address type, receive and change branches, and a known transaction. Re-importing a public record cannot recover a lost private key.

A watch-only interface may show a large amount that its operator cannot spend. The capability demonstrated is observation, not signing authority. Even a signer must satisfy the output’s actual conditions, which may include multiple keys or timelocks. Avoid treating one displayed “balance” as a complete account of access.

No. Public derivation information can help identify outputs, but it does not reconstruct the missing secret required to sign their spending transactions.
