WalletConnect is an open-source protocol designed to establish a secure and reliable connection bridge between decentralized applications and cryptocurrency wallets. WalletConnect is a key component of Web3 infrastructure, enabling interaction between user wallets (especially mobile wallets) and various decentralized applications in a secure, convenient, and standardized way. It greatly enhances the user experience while adhering to the core security principle of 'private keys never leaving the user's device,' promoting the popularization and development of decentralized applications. With the maturity of v2 and the ongoing expansion of the ecosystem, WalletConnect will continue to play an important role in connecting the Web2 and Web3 worlds.
