2. How does WalletConnect work?
When a user enters a decentralized application (such as Uniswap, OpenSea, etc.), a QR code is displayed.
The user scans it through a WalletConnect-enabled wallet app.
An encrypted communication channel is created between the two parties.
The user signs transactions from within his wallet without having to give his private data or private key to the application.
