How do I pair MetaMask with WalletConnect?

What Is WalletConnect and Why Pair It with MetaMask?

WalletConnect is an open-source protocol that enables secure communication between mobile wallets and decentralized applications (dApps). By using a QR code or deep link, users can connect their mobile wallet to a desktop browser seamlessly. MetaMask, one of the most popular Ethereum-based wallets, supports integration with WalletConnect to provide a more flexible experience for users who prefer managing assets on mobile devices.

Pairing MetaMask with WalletConnect allows users to interact with dApps directly from their mobile device while maintaining the security of private keys stored locally. This setup is especially useful when accessing platforms that don’t natively support mobile browsers but work well through desktop extensions.

Preparing MetaMask for WalletConnect Integration

Before initiating the pairing process, ensure you have the following:

• A functional MetaMask account installed either as a browser extension or mobile app.
• The WalletConnect-enabled dApp or service you want to access should be open and ready in your browser.
• Your mobile device must have internet connectivity and allow camera permissions if scanning a QR code.

Open the MetaMask mobile app and navigate to the 'Browser' section or launch the desktop version of MetaMask connected to your preferred browser. Make sure all updates are applied to avoid compatibility issues during the pairing process.

Initiating the Connection via WalletConnect

When visiting a dApp that supports WalletConnect, look for a 'Connect Wallet' button. Upon clicking it, a list of wallet options will appear. Choose WalletConnect from the list instead of selecting MetaMask directly.

After selecting WalletConnect, the dApp will display a QR code on your screen. Open the MetaMask mobile app, tap the scan icon located at the top right corner, and point your camera at the displayed QR code. Ensure the entire code is visible within the frame for accurate scanning.

Once scanned successfully, MetaMask will prompt you to approve the connection request. Tap “Approve” to proceed.

Confirming the Connection and Signing Transactions

After approval, the dApp will recognize your MetaMask wallet and display the connected address. You can now interact with smart contracts, swap tokens, stake assets, or participate in governance activities depending on the platform's features.

Whenever a transaction needs signing, MetaMask will send a push notification or display a confirmation screen within the app. Review the details carefully, including gas fees, recipient address, and transaction data. Tap “Sign” to authorize the action. Never skip this step, as incorrect approvals may lead to irreversible loss of funds.

If prompted for signature requests multiple times, ensure each one corresponds to the intended action. Some dApps may require multiple approvals for different functions such as token allowance and execution.

Troubleshooting Common Issues During Pairing

Occasionally, users may face difficulties connecting MetaMask with WalletConnect due to network issues, outdated software, or permission restrictions. If the QR code fails to scan, check your mobile camera settings and ensure no obstructions are blocking the lens.

If the connection fails repeatedly, try refreshing the dApp page and re-initiating the WalletConnect flow. Also, verify that both your browser and MetaMask mobile app are updated to the latest versions.

In some cases, MetaMask might not detect the WalletConnect session automatically. Restarting the app or clearing cache data could resolve such issues. Always ensure a stable internet connection on both your desktop and mobile device.

If the problem persists, consider switching networks within MetaMask to match the chain required by the dApp. For example, if the dApp operates on Binance Smart Chain, switch MetaMask accordingly before reconnecting.
