I. Basic Concepts of Web3 Wallets

A Web3 wallet is a digital wallet designed for the decentralized internet (Web3), primarily used to store and manage cryptocurrencies and digital assets. Unlike traditional financial systems, most Web3 wallets are non-custodial, giving users full control over their private keys and ensuring security and anonymity in transactions and asset management. Web3 wallets can not only store digital currencies but also interact with smart contracts, participate in decentralized finance (DeFi), non-fungible tokens (NFTs), and other ecosystems.

3. Types of Web3 Wallets

Web3 wallets can generally be divided into two categories: software wallets and hardware wallets.

Software wallet

Software wallets provide services through browser extensions or mobile applications, allowing users to conveniently conduct transactions and manage assets anytime and anywhere. Common software wallets include MetaMask, Trust Wallet, and others. Most of these wallets are user-friendly and suitable for beginners.

Advantages

Easy to use, simple to operate, and suitable for daily transactions.

Supports multiple cryptocurrencies, allowing for easy cross-asset management.

Disadvantages

Because it is an online application, its security is relatively low and it is vulnerable to hacker attacks.

Hardware wallet

A hardware wallet is a physical device specifically designed to store cryptocurrencies, such as Ledger, Trezor, and others. Hardware wallets keep users' private keys and conduct transactions offline, thereby providing a higher level of security.

Advantages

Highly secure, protecting user assets from cyber attacks.

The user's private key is not exposed to the network environment, reducing the risk of theft.

Disadvantages

It is relatively less convenient, as users need to connect a device when using it.

How to set up a Web3 wallet

When you start using a Web3 wallet for payments, you first need to create a wallet account. Here are the main steps in the setup process.
