WalletConnect is a simple and secure cross-platform crypto wallet connection tool that allows users to easily connect their mobile wallets to desktop DApps or decentralized apps without having to enter private keys on the browser, which improves security and ease of use. In this article, we will analyze the use of WalletConnect from installation, setup to operation to help you better understand and start using this wallet tool.
What is WalletConnect?
WalletConnect is an open source protocol designed to help securely connect cryptocurrency wallets to decentralized applications (DApps). Simply put, it is a cross-platform crypto wallet connection technology that supports seamless communication between devices. For example, you can connect your mobile phone's crypto wallet to a decentralized exchange (DEX) or other DApp on your desktop browser without having to enter sensitive private key information directly on the desktop. This not only improves security, but also makes cryptocurrency easier to use.
How to install WalletConnect?
The process of installing WalletConnect is very simple, first you need to make sure you have an encrypted wallet that supports the WalletConnect protocol. Here are the steps:
Download wallets that support WalletConnect: Many popular crypto wallets support the WalletConnect protocol, such as MetaMask, Trust Wallet, Coinbase Wallet, and others. You can download and install one of these wallets from the App Store or Google Play.
Setup Wallet: After installing your wallet, open and setup your wallet. Follow the wallet prompts to create a new wallet or restore an existing one.
Configure WalletConnect: After opening the wallet, go to Settings or Connections in the wallet and find the WalletConnect function. Once enabled, the wallet will generate a QR code that can be scanned on other devices to connect.
How to connect WalletConnect to DApp?
Once you have installed and configured WalletConnect-enabled wallets, the next step is to connect the wallet to a decentralized application (DApp). The process is as follows:
Open a DApp platform: for example, a decentralized exchange (DEX) or NFT marketplace, which usually supports the WalletConnect feature. Once on the website, select the "WalletConnect" option.
Select WalletConnect: On the wallet selection page, select "WalletConnect" as your wallet connection method. A QR code will be displayed.
Scan QR Code: Use your encrypted wallet to scan the QR code displayed on the website to complete the connection.
Authorized Transactions: After connecting, you can directly operate on the DApp platform, such as making transactions, viewing assets, and so on. All transaction authorization will be confirmed in your wallet to ensure security.
How do I make a transaction using WalletConnect?
After connecting to the DApp through WalletConnect, you can start performing various operations including trading, pledging, lending, etc. Below are the specific steps on how to trade with WalletConnect:
Choose a pair: After entering a decentralized exchange (e.g. Uniswap, Sushiswap), choose the token pair you want to trade.
Initiate a trade: After selecting the quantity to be traded, click the "Exchange" or "Confirm" button.
Authorize Transaction: At this point, Wallet will pop up a transaction authorization prompt to confirm the details of the transaction, including the transaction amount, handling fee and so on. If the information is correct, click "Confirm".
View Transaction Results: After the transaction is submitted, you can view the progress of the transaction in the DApp or wallet until the transaction is completed.
How secure is WalletConnect?
Security is a key issue in cryptocurrency trading and WalletConnect excels in this area. Below are WalletConnect's security measures:
No need to expose private key: When using WalletConnect to connect to DApp, the private key is always stored inside your wallet, which means that even if the DApp is controlled by an attacker, your private key won't be exposed, lowering the risk of funds being stolen.
2D encrypted communication: WalletConnect connects via encrypted 2D communication, ensuring security when operating across devices.
Multi-Level Confirmation: Each transaction or operation requires the user to confirm in the wallet, adding an extra line of security.
Open Source Protocol: As an open source project, WalletConnect's code is transparent and can be audited by the developer, which allows system vulnerabilities and potential security issues to be discovered and fixed more quickly.
