What Is WalletConnect & How Does It Work?

·

Cryptocurrency wallets are more than just digital vaults for storing assets—they serve as essential gateways to the decentralized web, commonly known as Web3. As decentralized applications (DApps) continue to grow in popularity across blockchains like Ethereum and BNB Smart Chain, users need a seamless and secure way to interact with them. This is where WalletConnect comes in.

WalletConnect is an open-source protocol designed to bridge mobile crypto wallets and DApps using secure, encrypted connections. Unlike browser extension wallets that run directly in your web environment, WalletConnect enables users to link their mobile wallets to web-based DApps through QR code scanning or deep links—keeping private keys safely stored on the user’s device at all times.

This method not only enhances security but also gives developers a universal solution for integrating wallet functionality without needing native support for every individual wallet.

How Does WalletConnect Work?

At its core, WalletConnect establishes a secure, end-to-end encrypted communication channel between a mobile wallet and a DApp. The connection process is simple, intuitive, and works across platforms—whether you're on desktop or mobile.

Let’s walk through a real-world example using PancakeSwap, a leading decentralized exchange on BNB Smart Chain, and Trust Wallet, a widely used multi-currency mobile wallet.

Step 1: Access the DApp

Open your preferred browser and navigate to the official PancakeSwap website: https://pancakeswap.finance. Always ensure you’re on the correct site to avoid phishing scams.

Once loaded, locate the “Connect Wallet” button—typically found in the top-right corner of the interface.

Step 2: Select WalletConnect

Clicking “Connect Wallet” will display several options. Choose WalletConnect. This action generates a unique QR code on your screen—a temporary token that represents your connection request.

Step 3: Open Your Mobile Wallet

Now switch to your smartphone and open Trust Wallet (or any WalletConnect-compatible app). Navigate to Settings > WalletConnect > New Connection.

Step 4: Scan the QR Code

Use your phone’s camera or the built-in scanner within the app to scan the QR code displayed on your computer screen. The connection is established instantly via an encrypted bridge, often using relay servers that do not store data.

Step 5: Approve the Connection

After scanning, your wallet will prompt you to confirm the connection. Review the details and tap “Connect”. You’ll be redirected back to PancakeSwap, now showing your wallet as connected.

This means you can now interact with the DApp—swap tokens, provide liquidity, stake assets—all while keeping control of your funds.

Step 6: Initiate a Transaction

Return to PancakeSwap and click “Trade Now”. Let’s say you want to swap BNB for ETH. Enter the amount, review fees and slippage tolerance, then click “Swap”.

Step 7: Confirm on Your Mobile Device

Instead of confirming directly in-browser, WalletConnect sends the transaction request back to your mobile wallet. Here, you must manually approve it. If prices change during execution, you may see an “Accept Price Update” prompt—another layer of user control.

Once confirmed, the blockchain processes the transaction. Check your Trust Wallet for confirmation—it may take a few moments depending on network congestion.

Step 8: Disconnect After Use

For added security, always disconnect after completing your session. In Trust Wallet, go to WalletConnect > Active Sessions > Disconnect. This terminates the session and prevents lingering access.

Supported Mobile Wallets

One of WalletConnect’s biggest strengths is its broad compatibility. It supports over 150 mobile and desktop wallets, making it one of the most universally adopted protocols in Web3.
