@WalletConnect
1. Basic Introduction**
WalletConnect is an open-source Web3 communication protocol that allows users to securely connect decentralized applications (DApps) to mobile wallets (such as MetaMask, Trust Wallet, etc.) by scanning QR codes or deep links. It employs end-to-end encryption (E2EE) technology to ensure that sensitive operations like transaction signing are performed locally, reducing the risk of private key leakage.
2. Core Advantages**
- **High Security**: Private keys are always stored in the user's wallet, and DApps cannot access them directly, reducing the risk of phishing attacks and malicious scripts.
- **Cross-chain Compatibility**: Supports multi-chain ecosystems like Ethereum, Solana, and Cosmos, enhancing interoperability.
- **Optimized User Experience**: Connecting is as easy as scanning a QR code on mobile, making it more convenient than browser plugin wallets, especially suited for mobile DeFi and NFT applications.
- **Decentralized Architecture**: WalletConnect 2.0 introduces relay servers (Relay Network), reducing dependence on a single centralized service.
3. Potential Challenges**
- **Dependence on Wallet Support**: If mainstream wallets do not integrate WalletConnect, its usage will be limited.
- **Network Latency Issues**: Dependency on relay servers may lead to unstable connections, affecting transaction experience.
- **Privacy Concerns**: Although data is encrypted, relay nodes may record connection behaviors, raising privacy concerns for some users.
