What a wallet actually stores

The app manages access; the network records balances.

LET’S PICTURE IT

A library card helps you use a library. It does not contain the books or the library’s borrowing register.

An address is public receiving information. It is not the private key that authorizes actions.

Animated local teaching model. No wallet, RPC or live blockchain data. Some labels and hashes are abbreviated for readability.

The balance lives on the network

A wallet displays information about accounts, often by asking a node for data. Deleting the app does not delete those network balances. Restoring access depends on the account’s authorization and recovery method.

Different wallets keep different things

A software wallet may keep encrypted key material on the device. A hardware wallet performs signing inside a separate device. A watch-only wallet can keep public addresses without having the keys needed to authorize spending.

The interface adds a useful view

Labels, cached activity and preferences may exist only in a particular app. Those details can disappear when you reinstall or switch software even though the underlying account remains. A token being hidden in the interface is different from a zero onchain balance.

Know what your backup restores

A recovery phrase may restore key-based accounts, but an app’s labels or a contract wallet’s configuration can require separate information. Read the wallet’s recovery instructions before relying on an assumption about what one backup covers.

QUICK CHECK · NO PRESSURE

Does uninstalling a wallet app erase its accounts’ onchain balances?
