What is a crypto wallet

A private key is cryptographic code represented as a string of letters and numbers, similar to a password. In cryptocurrency, private keys are used to sign transactions, approve interactions with smart contracts, and prove ownership of a blockchain address. Crypto wallets store your private keys, keep them secure and accessible and allow you to send and receive cryptocurrencies.

Crypto wallets come in many forms, from hardware wallets like Ledger & Trezor, to mobile apps like Trustee Wallet, to browser extensions like Frame or MetaMask. Hardware wallets are typically USB devices connected to your computer via a cable. Hardware wallets contain private keys and are password secured, and you must enter your password to sign transactions and interact with smart contracts.

Mobile wallet apps offer crypto users a user experience similar to banking apps in that you control your funds through a mobile application. Typically, mobile apps are less secure than using a hardware wallet. Browser extensions, like Frame or Metamask, reside in your internet browser and offer higher ease of use, with the downside of being less secure, than a hardware wallet.
