When you use your wallet to scan a QR code to log into a dApp or confirm a signature, have you ever wondered how this 'smooth experience' is achieved? The answer lies in the open-source protocol known as WalletConnect—it acts as a universal USB interface in the Web3 world, allowing wallets and dApps to communicate securely across the technical divide, while your private keys remain firmly in your control.

Secure connections, private keys never leak

The core value of WalletConnect lies in its security architecture. Users establish connections by scanning encrypted QR codes or deep links, with all communication protected by end-to-end encryption and Transport Layer Security (TLS) protocols. Most importantly, private keys are always stored in the user's local wallet; the dApp only obtains transaction signing permissions, fundamentally eliminating the risk of private key leakage. This 'no-touch-key' design makes it a trusted cornerstone for connecting over 500 wallets like MetaMask and Trust Wallet with over 6,000 dApps such as Uniswap and Aave.
