**WalletConnect (WCT)** is a protocol that enables secure communication between decentralized applications (dApps) and cryptocurrency wallets. It allows users to connect their wallets to dApps without exposing private keys, enhancing security and usability.
### **Key Features of WalletConnect:**
1. **Cross-Platform Compatibility** – Works with mobile, desktop, and web wallets.
2. **End-to-End Encryption** – Uses secure QR code scanning or deep linking for connections.
3. **Multi-Chain Support** – Compatible with Ethereum, Solana, Cosmos, and other blockchains.
4. **No Custody** – Users retain full control of their private keys.
5. **Open-Source** – Transparent and community-driven development.
### **How WalletConnect Works:**
1. **Scan QR Code** – A dApp generates a QR code that the wallet scans to establish a connection.
2. **Secure Session** – Communication happens via encrypted relay servers.
3. **Approve Transactions** – Users sign transactions directly from their wallets.
