Wallet

A cryptoasset wallet is a system for managing keys, addresses, and transaction signing rather than a container that physically stores blockchain assets.

Assets remain recorded on the network, while the wallet enables authorized instructions using the relevant private keys. Wallets can be custodial or user controlled, hot or cold, and may support multiple networks whose addresses look similar but are not interchangeable. Security depends on software integrity, authentication, backups, transaction review, and recovery practices, and mistaken or malicious transfers are often irreversible.

Before signing, verify the destination, asset, network, amount, and smart-contract permissions on a trusted display.
