@WalletConnect $WCT #WalletConnect DeFi interaction security is a common topic, but recently, gas fees have soared, causing significant losses on small transactions. Is there a safer solution? I have seen some developers discussing the use of off-chain signatures, in conjunction with the WalletConnect protocol, to achieve transaction preview and authorization. This idea is quite interesting, as it adds a layer of 'insurance' to transactions. Users can confirm transaction details in their local wallets, avoiding being 'phished' by malicious contracts. Although it may be somewhat complex to implement, it can save frequent DeFi users a lot of unnecessary expenses. Looking forward to seeing more security innovations based on WalletConnect.
