Don't just know how to scan! WalletConnect's 3 hidden security features can prevent 80% of on-chain risks
Most users have only experienced WalletConnect's "scan to connect," but there are 3 hidden security features behind it that can help you avoid most pitfalls, and many seasoned players may not even know them all.
The first is "session expiration reminder": If you connect your wallet to a DApp and do not interact again for over 7 days, WalletConnect will automatically disconnect this "session connection." For example, if you scanned a code on a small DApp 10 days ago and now reopen that DApp, you will find that you need to scan the code again. This prevents someone from using your phone to secretly operate your assets with your previous connection.
The second is "phishing link detection": WalletConnect will compare the DApp's domain and official registration information in real time. If it detects that you are visiting a counterfeit site (for instance, changing "Uniswap" to "Uniswop"), your wallet will prompt a red warning, reminding you that "this DApp has risks." Last year, a counterfeit DApp mimicked Aave's interface and deceived many users into granting permissions, but 80% of users who connected through WalletConnect avoided the scam because of this warning.
The third is "real-time interaction monitoring": No matter what operation you initiate on the DApp (such as authorizing tokens or transferring funds), WalletConnect will synchronize the operation details (including how much gas fee is needed and the address of the authorized contract) to your wallet for confirmation. Previously, there was a DApp that attempted to secretly grant users "unlimited transfer permissions," but the discrepancies between the details shown in the wallet and the DApp interface were detected by users, leading to reports. Together, these features enhance the security of the billions of dollars in assets flowing through WalletConnect each year, making it safer than other connection tools by more than one level.
