WalletConnect is an open-source protocol used to establish a connection between various wallets and decentralized applications (dApps). WalletConnect simplifies the integration of crypto wallets and dApps for developers, ensuring effortless connections. Its innovative Mobile Linking technology enables the seamless establishment of connections between crypto wallets and dApps. 

By leveraging a shared key, WalletConnect establishes an encrypted connection, facilitating interaction between DApps and WalletConnect-compatible wallets. While the specific steps may vary slightly between web and mobile browsers, the underlying process ensures secure transactions and protects user privacy by avoiding the disclosure of personal identifying information. This protocol offers a level of safety and confidentiality that traditional browser extensions cannot guarantee.

To illustrate the mechanics of WalletConnect, let’s consider a scenario where a DApp on a website browser connects to a crypto wallet on a smartphone.

Connecting DApps and wallets with WalletConnect

WalletConnect seamlessly integrates with over 170 crypto wallets, including MetaMask, Rainbow, Trust Wallet, Argent, and many more. Utilizing WalletConnect is an easy process that involves accessing the dApp through its official website and connecting one crypto wallet. 

The connection between wallets and decentralized applications (dApps) is established securely and effortlessly through either QR code scanning or deep linking. Here’s a step-by-step breakdown of the process:

1. Visit the official DApp website 

Always ensure that you use the official domain of the DApp you want to access to guarantee a secure and private connection. After that, launch the DApp

2. Connect a crypto wallet 

Choose the option that allows you to connect a crypto wallet and select WalletConnect to get a QR code display. Then, open the selected crypto wallet app, go to the Settings tab, and select WalletConnect to establish a new connection. Scan the browser’s QR code. 

The protocol will redirect you to the DApp, and you can connect or link your digital wallet to start a transaction.

3. Start trading 

Once in the DApp, you can swap, borrow or lend your crypto. To proceed, enter the details of the assets you wish to exchange. For instance, you might enter the number of ETH you wish to swap for SOL.

If the price changes during the transaction, a pop-up message will appear, requiring you to accept. Note that transactions may take a few seconds to complete. Ensure to verify the swap before finalizing the transaction. 

You can also confirm the transaction on your connected crypto wallet app. Keep in mind that the transaction duration can vary from a few seconds to a couple of minutes.

4. Disconnect WalletConnect 

After successfully completing the transaction, disconnect WalletConnect from the chosen crypto wallet. You can do this via the DApp web browser or the crypto wallet app, depending on your selected platform.
