What is Cryptocurrency Wallet?

Cryptocurrency wallets come in a variety of forms, their most basic function is to store a user's private and public keys and interact with various blockchains enabling users to send and receive digital currency and monitor their cryptocurrency balances. Wallets have a public address that can be given out for people to send you digital assets, and a private key to confirm the transfer of digital assets to others. Wallets can be digital (software) or physical (hardware), hot (connected to the internet) or cold (disconnected from the internet), custodial (a trusted third party has control of a user's private keys) or non-custodial (only the user controls their private keys).
