How to securely connect a mobile wallet to a decentralized application via Wallet Connect

Wallet Connect is an innovative protocol that allows users to securely connect a wallet from their mobile device to decentralized applications (dApps) directly in the browser. This technology solves the problem of convenience and security by allowing you to maintain control over private keys on your mobile device while using the dApp on your computer. The process of connecting a wallet through Wallet Connect is standardized, making it accessible to users of all experience levels.

Why do you need Wallet Connect and how does it work?

Wallet Connect is used on many popular platforms, including PancakeSwap, UniSwap, and other leading DeFi services. The main advantage of this solution is that you can interact with the dApp in the browser without storing private keys on the computer. Instead, all critical transactions are confirmed directly on your mobile wallet (e.g. Trust Wallet), where your funds are safe. This is much safer than using browser extensions like MetaMask on an unsecured computer.

Step-by-step instructions for connecting a wallet

Starting the process on the browser side: Open the selected decapitralized application in your computer’s browser. On the main dApp page or in the interface menu, find the “Connect Wallet” button. Usually, you will see several connection options - MetaMask, WalletConnect, and others. Select the Wallet Connect option. Once selected, a unique QR code will appear on the browser screen.

Activation on a mobile device: Open your mobile wallet app on your smartphone. If you’re using Trust Wallet, go to Settings or click on the options icon. Find the “Wallet Connect” feature in the app menu. It is usually located in the main menu or in the connections section. Select “Wallet Connect” and allow the app to use your phone’s camera.

Scan & Confirmation: Using the built-in camera in your wallet app, scan the QR code displayed in your browser. The system will instantly recognize the code data and show you the name and address of the dApp you’re trying to connect to. Check the information carefully to make sure it’s the app you really need. Click “Confirm” or “Accept” in the mobile app to complete the wallet connection. After that, your wallet will be connected to the dApp in the browser.

Performing Operations and Confirming Transactions

You are now ready to use the app from your browser. When you initiate any operation on the dApp – whether it’s a token swap, staking, or other transaction – a confirmation prompt will automatically appear in your mobile wallet app. You will be able to view the details of the transaction, including the recipient, amount, and gas fee. If necessary, you can edit the gas parameters (gas price) to optimize costs, or reject the operation if something alerts you. All decisions are made from your mobile device, giving you complete control and security.

Using Wallet Connect is a reliable way to interact with the DeFi world while maintaining full control over your assets and private keys. This approach is more reliable than trusting your keys to browser extensions on an unprotected computer.
