A Web3 wallet is more than just a way to store cryptocurrency, it's a tool for controlling blockchain accounts, managing digital assets, and connecting to decentralized applications (dApps).
Unlike traditional exchange accounts or crypto wallets, Web3 wallets give users direct control over their on-chain actions. This means they can send tokens, hold NFTs, connect to dApps, and prove ownership without a traditional login.
Web3 wallets work by managing public/private key pairs. The private key is a randomly generated secret that the wallet software stores or a hardware wallet keeps separate. From this private key, the wallet derives a public key, which forms the user's wallet address.
The main types of Web3 wallets include browser extension wallets, mobile wallets, hardware wallets, hot wallets, cold wallets, custodial wallets, non-custodial wallets, and smart contract wallets. Each type balances convenience, security, and control differently.
