Wallet

Also called: Crypto Wallet

Common prompts: "what is a crypto wallet," "hot wallet vs cold wallet," "best crypto wallet"

Definition

A crypto wallet is software or hardware that stores the private keys used to access and control cryptocurrency on a blockchain. Wallets range from custodial (a third party holds the keys) to non-custodial (the user holds the keys), and from always-online hot wallets to offline cold wallets — each trading convenience against security.

Why it matters

The wallet is most users' first and most consequential decision in crypto, balancing security against ease of use. Newcomers research wallet options heavily, asking AI engines which is safest and which is best for their needs. Wallet providers compete on trust, security, and clarity — and those that surface authoritatively in the answer layer capture users at the critical onboarding moment.

Example

A wallet provider publishes structured content explaining custodial versus non-custodial and hot versus cold options — surfacing as the cited answer when newcomers research which wallet to choose.
