What is WalletConnect?

WalletConnect is an open-source protocol that allows you to connect your mobile wallet to decentralized applications (dApps) on desktop or web platforms using QR code scanning or deep linking.

Launched in 2018, WalletConnect has grown to become one of the most widely adopted solutions for secure Web3 interaction, offering support for hundreds of wallets and applications.

Key Features of WalletConnect

  1. Secure Communication WalletConnect encrypts all messages between the wallet and the dApp using a shared key. This ensures end-to-end encryption and security of your private data.
  2. Session Management You can approve or reject a session request, and each session lasts until you disconnect it manually from your wallet.
  3. Cross-platform Compatibility WalletConnect works with mobile, web, and desktop applications. QR codes and deep linking allow for quick and seamless pairing.
  4. Multi-chain Support WalletConnect supports various blockchain networks such as Ethereum, BNB Chain, Polygon, Avalanche, and more.
  5. Wide Wallet Integration It is integrated with over 200 crypto wallets like MetaMask, Trust Wallet, Rainbow, Argent, and more.
  6. Push Notification Support With the WalletConnect v2 update, the protocol supports push notifications for transaction requests and app interactions.

How Does WalletConnect Work?

The WalletConnect connection process is simple and user-friendly:

  1. A dApp generates a QR code or a deep link.
  2. The user scans the QR code with a supported mobile wallet or clicks the deep link.
  3. The wallet and the dApp establish a session using encrypted communication.
  4. The user approves transactions or messages from within the mobile wallet.

The protocol works over a relay server but uses end-to-end encryption, meaning no data is visible to intermediaries.
