What is a crypto wallet

A crypto wallet is a tool that allows users to store, send, and receive cryptocurrency.

The wallet stores private keys, which provide access to funds on the blockchain. A crypto wallet can be a browser extension, a mobile or desktop application, or a hardware device such as Ledger.

How a crypto wallet works​

Every wallet contains two types of cryptographic keys:

  • public key
  • private key

The public key is used to receive funds, while the private key is used to sign transactions.

Private keys must never be shared, because anyone who has access to them can control the associated crypto assets.
