A crypto wallet (crypto wallet, digital wallet) is a software or hardware solution that provides access to a user's cryptocurrency funds. It is important to understand that the coins themselves are stored in the blockchain, while the wallet manages cryptographic keys — a public address for receiving transfers and a private key for confirming operations. Whoever controls the private key effectively controls the assets, so keeping it safe and protected plays a key role.

Types of crypto wallets

• Multi-currency — support many coins and tokens at once.
• Single-coin — designed to work with one specific currency.
• Hot — connected to the network (mobile, desktop, web wallets), convenient for frequent operations.
• Cold — isolated from the internet (hardware devices, paper media), suitable for long-term storage.

Separately, a distinction is drawn between custodial wallets, where the keys are managed by a third-party service, and non-custodial ones, where the private key and seed phrase are held only by the owner. The choice depends on priorities: convenience and support versus full self-custody of funds and the responsibility that comes with it.
