Watch-Only Wallet

A watch-only wallet contains public keys or addresses but no private keys, letting its user monitor balances and generate receive addresses while remaining unable to spend. It is usually created by importing an extended public key, from which all of a wallet's addresses, potentially millions of them, can be derived.

Why it matters

Watch-only wallets separate visibility from spending power, which is the foundation of serious cold storage practice. The online phone or laptop watches the chain and prepares transactions; the offline signer holds the keys and approves them. A business can give its accountant full visibility into treasury flows with zero ability to move funds, and a family can monitor inherited coins without touching the keys that control them.

The privacy caveat is significant: an extended public key links every address it derives, so sharing it reveals the wallet's entire past and future transaction history to whoever holds it.

In the gold vs bitcoin debate

A gold owner cannot check vaulted bars from a phone; verifying metal means audits, custodial statements, and trust in whoever runs the vault. A bitcoin holder's watch-only wallet verifies cold-stored coins against the public chain every minute of every day, at no cost and with no permission. Continuous, independent auditability of an asset locked away in deep storage is something physical custody simply cannot replicate.
