What Is WalletConnect?

WalletConnect is essentially a bridge that facilitates communication between DApps and wallets. Instead of manually copying and pasting wallet addresses or private keys, users can simply scan a QR code or click a deep link to establish a connection. This protocol supports multiple wallets and DApps, making it a versatile and widely adopted solution in the decentralized finance (DeFi) ecosystem.

How Does WalletConnect Work?

Establishing a Connection

1. Initiating the Connection:

• When a user wants to interact with a DApp, they will be presented with a WalletConnect option.
• The DApp displays a QR code or a deep link for the user to scan or click.

2. Scanning the QR Code:

• Using a WalletConnect-compatible mobile wallet, the user scans the QR code displayed by the DApp.
• Alternatively, if the user is on a mobile device, they can click the deep link, which will open their wallet app directly.

Secure Communication

1. Pairing Session:

• Upon scanning the QR code or clicking the deep link, the wallet and the DApp establish a pairing session.
• This session is encrypted, ensuring that all data transmitted between the wallet and the DApp remains secure and private.

2. Transaction Signing:

• When the user initiates a transaction on the DApp, such as a token transfer or a swap, the transaction details are sent to the wallet through the secure WalletConnect session.
• The user can review the transaction details in their wallet app and approve or reject the transaction.

Completing the Interaction

1. Broadcasting the Transaction:

• Once the user approves the transaction, the wallet signs it with the user's private key and broadcasts it to the blockchain.
• The DApp receives confirmation that the transaction has been signed and submitted.

2. Ending the Session:

• After completing their interactions, users can disconnect the session from either the wallet or the DApp, ending the secure communication channel.
