Recently participated in Binance's TGE, and found that every time I pre-authorized on BSCScan, a QR code scanning interface would pop up. Using Binance's keyless wallet to scan, the signature was completed in seconds without the need to export the private key, providing a very smooth experience. This made me curious about what WalletConnect is, and I discovered that it is not a wallet, but an open-source protocol used to connect wallets and DApps.
It is not a wallet, but a 'bridge'. WalletConnect itself does not store assets or generate accounts; its role is to establish an encrypted communication channel between wallets and DApps. Users can connect by scanning a QR code or clicking a link, without needing to install a plugin or expose their private keys.
Why is it so easy to use?
1. Scan to connect, cross-device compatibility: Supports mobile QR scanning and web interaction.
2. End-to-end encryption: Transaction signatures need to be confirmed by the user in the wallet, and private keys are always stored locally.
3. Strong compatibility: Supports hundreds of wallets and hundreds of chains, including Ethereum, BSC, Solana, etc.
Workflow:
1. DApp generates WalletConnect QR code;
2. User scans QR code to establish connection;
3. Confirm request in wallet and complete the signature.
WalletConnect is the 'Bluetooth protocol' of the Web3 world, allowing us to interact securely with multiple DApps using one wallet. It is not a conspicuous product, but a key underlying element that enhances the blockchain user experience.
