What is WalletConnect?
WalletConnect is an open protocol that lets you connect desktop DApps to mobile wallets using end-to-end encryption by scanning a QR code.
To establish the connection between the NCW app and the DApp on your laptop or desktop, WalletConnect works similarly to scanning a QR code to log in to the WhatsApp web.
A supported DApp will allow you to access your wallet address by scanning a QR code with your mobile wallet. Once scanned, the mobile app will ask you to confirm that you want to share your wallet address with the DApp.
Once this is confirmed, the DApp won’t actually be able to send any transactions from the address that was just connected on its own.
You must make an additional, manual confirmation for each transaction that’s made on the DApp interface from your mobile device. This way, the private key is always securely stored on your device, and you have full control of which transactions get broadcast to the network.
