What is a Web3 Wallet?

A Web3 wallet is a digital tool that allows you to store, manage, and interact with cryptocurrencies and blockchain-based applications. Think of it as your personal interface to the decentralized web, combining the functions of an identity provider, a bank account, and an authentication system into a single application.

Unlike traditional digital wallets that store payment card information or hold balances on a company's servers, Web3 wallets give you direct control over your assets through cryptographic keys. Your wallet doesn't actually store your crypto; instead, it holds the private keys that prove ownership of assets recorded on the blockchain.

Public Keys, Private Keys, and Seed Phrases

Every Web3 wallet operates on two fundamental components:

When you create a wallet, you'll also receive a seed phrase, typically 12 or 24 words, that can regenerate your private keys if needed. This seed phrase is essentially the master backup of your entire wallet.
