Of course you can. Below is an article about WalletConnect that is suitable for a technical blog, blockchain project documentation, or a popular science platform. If you have a specific audience (developers, ordinary users, beginners, etc.), I can also adjust it.
What is WalletConnect? Learn about the Web3 wallet connection protocol in one article
With the rapid development of the blockchain ecosystem, the demand for interaction between users and decentralized applications (DApps) is becoming stronger and stronger. WalletConnect was born in this context. It is an important bridge connecting user wallets and DApps, allowing users to safely and conveniently interact with Web3 between different devices.
1. WalletConnect Introduction
WalletConnect is an open source protocol that allows users to connect their mobile wallets to DApps on the web or desktop by scanning a QR code or clicking a deep link.
Simply put, it is a communication protocol, not a wallet or application. Its role is to provide a standardized and secure communication method for wallets and decentralized applications.

2. Why do we need WalletConnect?
In Web2, users usually log in to applications with their account and password. In the Web3 world, users use crypto wallets such as MetaMask, Trust Wallet, TokenPocket, etc., which perform identity authentication and transaction operations through private key signatures.
However, most wallets are mobile applications, while most DApps are web services, which brings difficulties to the connection.
WalletConnect solves two key problems:
1. Device compatibility issues: Allow mobile wallets to connect and communicate with web DApps;
2. Security issues: The private key never leaves the wallet, and all signing operations are completed locally to avoid the risk of leakage.
3. How WalletConnect works
The core of WalletConnect is a message transmission mechanism based on encrypted WebSocket or Push channels. Its typical process is as follows:
1. The user clicks “Connect your wallet using WalletConnect” on the web DApp;
2. The DApp displays a QR code (including connection information);
3. The user scans the QR code using their mobile wallet;
4. The wallet and DApp establish an encrypted channel, and both parties can communicate in both directions;
5. When the DApp initiates a signature request or transaction, the user will receive a prompt on the phone;
6. After the user confirms, the wallet signs locally and returns the result to the DApp.
During the entire process, the private key is always saved on the local device, which is extremely secure.
4. Wallets and DApps that support WalletConnect
WalletConnect has been widely integrated into mainstream wallets and DApps:
• Wallets: MetaMask, Trust Wallet, Rainbow, TokenPocket, OKX Wallet, etc.;
• DApp: Uniswap, Aave, OpenSea, Zerion, 1inch and almost all mainstream DApps;
Developers can easily add wallet connection functionality to their applications by using the WalletConnect SDK.
5. New features of WalletConnect v2
With the rapid evolution of Web3, WalletConnect launched version v2 in 2023, introducing several key upgrades:
• Support multi-chain sessions (Multi-chain support);
• Use the more efficient and stable Waku network communication protocol;
• Stronger permission management and session control;
• Introduce the namespace mechanism to support parallel connections of multiple wallets and accounts.
WalletConnect v2 has gradually replaced v1, and developers should migrate as soon as possible to obtain better performance and compatibility.
VI. Conclusion
WalletConnect is an important protocol that connects Web3 wallets and DApps. It greatly improves the usability and user experience of decentralized applications through a secure and standard communication mechanism.
With the rapid development of Web3, WalletConnect has become an indispensable infrastructure.
