Crypto wallets come in a variety of shapes and sizes, but their primary function is to store a user’s private and public keys and interact with various blockchains, allowing users to send and receive digital currency and monitor their cryptocurrency balances. Wallets have a public address that people can use to send you digital assets, as well as a private key that can be used to confirm the transfer of digital assets to others. Wallets can be digital (software) or physical (hardware), hot (online) or cold (offline), custodial (a trusted third party controls a user’s private keys) or non-custodial (only the user controls their private keys).
