Introduction
Web3 wallets have become an indispensable tool for users who want to explore the world of cryptocurrency and decentralized finance (DeFi). In this guide, we will explore the basic concepts of Web3 wallets and introduce different types and popular wallet examples.
What is a Web3 Wallet?
Web3 wallets are digital wallets tailored for the world of decentralized finance (DeFi). This type of wallet is a portal for users to interact with blockchain networks and decentralized applications (DApp), providing a way to securely manage cryptocurrencies, NFT and other digital tokens.
Web3 Wallets vs Cryptocurrency Wallets
Although the two terms are often used synonymously, not all cryptocurrency wallets are compatible with DApp and DeFi platforms. Therefore, although cryptocurrency wallets and Web3 wallets are both used to manage cryptocurrencies, Web3 wallets support a wider variety of digital assets.
How Web3 Wallets Work
Most Web3 wallets strive to provide users with full control over their own digital assets. This means that users are responsible for managing their mnemonic phrase and private keys.
Generally, when you create a new Web3 wallet, a unique mnemonic of 12 or 24 words is generated. This mnemonic represents full access to your cryptocurrency wallet and its private key (used for signing). Never share your mnemonic and private key with others.
Main functions of Web3 wallet
Some features may vary from wallet to wallet, but most Web3 wallets share a key set of features:
Multi-asset and multi-chain support: Supports multiple blockchain networks and a variety of digital assets including cryptocurrencies and NFTs.
Smart Contracts and DeFi Interoperability: Facilitating frictionless interactions with smart contracts, enabling users to access DApps, decentralized exchanges (DEX), marketplaces, and other blockchain-based applications.
Peer-to-peer transactions: Allow users to send and receive digital assets without the need for centralized services or intermediaries.
Security: A good Web3 wallet should provide strong security and use encryption technology to protect mnemonics and private keys to avoid potential threats. Some wallets also have notification and reminder functions for potential malicious websites and smart contracts.
Anonymity: Although most blockchain transactions are public, users can create Web3 wallets without sharing sensitive data or personal information.
Comparison of Custodial and Non-Custody Web3 Wallets
1. Non-custodial wallet
Non-custodial or self-custodial wallets provide users with full control over their assets. Popular examples include MetaMask and Trust Wallet. For most traders and investors, non-custodial Web3 wallets are the safest option, as long as their private keys and mnemonics are kept private and secure.
2. Custodial wallet
Custodial wallets involve a third party that manages private keys on behalf of the user. The wallet in your Binance account is an example of a custodial wallet. This type of wallet offers convenience, but users must entrust their assets to a custodian, so it is important to choose an exchange that is reliable and trustworthy.
Web3 Wallet Types
There are many ways to categorize Web3 wallets and cryptocurrency wallets. In this section, we'll explore some of the most common types: hardware wallets, web wallets, desktop wallets, mobile wallets, paper wallets, and smart contract wallets. But keep in mind that there is overlap between the different categories. For example, a Web3 wallet like MetaMask can be both a web wallet and a mobile wallet, and provides support for hardware wallets like Trezor and Ledger.
Hardware wallets
Hardware wallets are physical devices that store your cryptocurrency keys offline (cold storage), providing an extra layer of security. These wallets are better protected against cyber threats and are relatively more secure, but they are a little more complicated to use and access. But if you plan to hold cryptocurrency for the long term or own a large amount of cryptocurrency, a hardware wallet may be a good choice.
You can set a PIN for extra security, and most of these wallets allow you to create backup phrases in case you lose your wallet. Trezor and Ledger are popular examples of hardware cryptocurrency wallets.
Online Wallet
Web wallets usually run in a browser interface and allow users to access their cryptocurrency holdings online. Most web wallets can now also be used as mobile wallets. These wallets are convenient, but users must be cautious when connecting their wallets to DeFi platforms and DApps. Interacting with malicious websites or smart contracts may put your assets at risk.
Mobile Wallets
The mobile wallet operates in a similar way to the web version, but is designed specifically for smartphones, allowing users to easily send and receive cryptocurrencies through QR codes; it also supports convenient access to DeFi and DApps through mobile devices.
However, mobile devices are vulnerable to malicious apps and malware, just like computers. It is recommended to protect mobile wallets by using password encryption and backing up your mnemonics (or private keys) in case your phone is lost or malfunctions.
MetaMask, Binance Web3 Wallet, and Trust Wallet are well-known examples of mobile cryptocurrency wallets. We will discuss these wallets in the next section.
Smart Contract Wallet
Smart contract wallets are managed by smart contracts on the blockchain. This type of wallet introduces programmable self-custodial accounts and improved functionality. Unlike traditional wallets, smart contract wallets allow users to specify rules and conditions for transactions, automate financial activities and enhance security through programmable logic.
Smart contract wallets typically provide users with decentralized control over their funds through blockchain technology and facilitate integration with DeFi applications. Security features such as multi-signature requirements, time locks, and upgradeability are common features of smart contract wallets, making them a versatile tool for managing and interacting with cryptocurrencies.
Desktop Wallet
Desktop wallets were more common in the early days of Bitcoin and cryptocurrency. These wallets are applications installed on a computer, and the user has full control over their cryptocurrency keys. Security depends on the integrity of the user's computer, and regular backups of wallet data are essential to prevent loss.
Paper Wallet
Many people consider paper wallets to be outdated and not recommended. These wallets are made by physically printing or writing down your cryptocurrency addresses and private keys on paper. These wallets are stored offline and are therefore resistant to online hacking attempts, but they need to be handled with care and stored securely to prevent physical damage or loss.
Web3 Wallet Example
MetaMask
MetaMask is one of the most popular non-custodial Web3 wallets, with the distinct advantage of being compatible with Ethereum and various EVM-compatible blockchains (such as BNB Chain, Polygon, Avalanche Compatible with Arbitrum, etc.).
Users can use MetaMask to interact with DApps, manage digital assets and exchange tokens. MetaMask puts user autonomy first and does not control user private keys, providing a safe and intuitive user experience for beginners and experienced users.
Binance Web3 Wallet
The Binance Web3 Wallet is integrated into the Binance App and serves both new and experienced DeFi users. The wallet utilizes Multi-Party Computation (MPC) technology to enhance cryptographic security by eliminating the need to store private keys in a single location. The wallet’s three “key shards” are distributed across the Web3 wallet, cloud storage, and the user’s device, and are further protected by a recovery password that only the user knows. This approach ensures enhanced security and reduces the risk of single points of failure.
Binance Web3 Wallet Features
Easy setup: Quickly create an account through the Binance App, without the need for mnemonics or private keys.
Convenient: Seamless connection with Binance Bridge and other services, making it easy to swap tokens and explore DApps.
Security measures: Supports wrong address protection and potential malicious smart contract detection, and transactions are controlled by multi-party computing (MPC) technology.
Self-custody: Encrypted by three “key shards” and a recovery password, it provides users with full autonomy over their assets.
Customer Support: 24/7 customer support ensures a safe and smooth experience for users.
Trust Wallet
Trust Wallet is another well-known non-custodial wallet that provides a hassle-free mobile experience for managing cryptocurrencies. Trust Wallet supports various blockchains, and its users can store assets, explore DApps, and participate in DeFi activities. Its user-friendly user interface and strong security measures make it an ideal choice for mobile users who value convenience and security.
Conclusion
For those exploring cryptocurrency and DeFi, Web3 wallets have become an indispensable tool to help them interact with blockchain networks and decentralized applications (DApps). Whether choosing MetaMask, Binance Web3 Wallet or Trust Wallet, users should always keep their mnemonics and private keys confidential and secure.
