The Ethereum community has introduced a major new security feature called Clear Signing to address one of the crypto industry’s biggest risks: blind signing. This feature lets users clearly see transaction details before approving them, instead of dealing with unreadable technical code or hex data.
The Ethereum Foundation described blind signing as a “structural flaw” that has caused billions of dollars in losses over the years. One major example was the large Bybit hack last year, where attackers changed transaction signatures using a compromised third-party provider.
Major self-custody wallet providers such as Ledger, Trezor, and MetaMask are already adding the new “What You See Is What You Sign” system. Instead of asking users to approve complex code they may not understand, this feature presents transaction details in a format people can easily read.
Trezor’s technology chief Tomáš Sušánka said many users approve harmful smart contracts without realizing it because they do not understand what they are signing. He called Clear Signing an important step forward for the industry’s security standards.
This project is part of the Ethereum Foundation’s Trillion Dollar Security Initiative and uses the open-source ERC-7730 token standard, which was first introduced by Ledger.
Other security-focused crypto companies and wallet providers have also contributed. The main goal is to make blockchain transactions safer and easier for everyday users as crypto scams become more advanced.
