How does WalletConnect work?
WalletConnect connects Decentralized Applications (DApps) to your web3 crypto wallet. When you attempt to connect a dApp with a mobile wallet, WalletConnect generates a QR code. This code is scanned by your mobile wallet, creating a secure connection between the two. This interaction does not require you to reveal your private keys, ensuring that your assets remain safe.
Here is a practical breakdown of how WalletConnect works:
- User Initiation: A user wants to interact with a dApp using their mobile crypto wallet.
- dApp Request: The dApp generates a request to connect with the user’s wallet.
- QR Code: WalletConnect generates a QR code that encapsulates this connection request.
- Scanning QR Code: The user scans this QR code using their mobile wallet app.
- Approval: The user reviews the request and approves it within their wallet.
- Secure Connection: Once approved, a secure and encrypted connection is established between the wallet and the dApp.
- Interaction: The user can now interact with the dApp securely through their wallet.

To set up WalletConnect, follow these steps:
- Install a mobile wallet that supports WalletConnect, such as Trust Wallet or Argent.
- Open your desired web-based dApp on a computer or browser.
- Click the option to connect a wallet, then select WalletConnect.
- A QR code will be displayed. Scan this using your mobile wallet.
- Upon successful scanning, you’ll receive a prompt on your mobile wallet to approve the connection. Once approved, the dApp and your wallet are securely linked.
