The Ethereum community has announced a feature that stops blind signatures

The Ethereum community has introduced Clear Signing, a security feature that allows users to clearly understand transaction details before signing, replacing unreadable hex data and mitigating blind signature attacks.

“Approving transactions is the last line of defense when it comes to controlling access to your assets on the blockchain. When done blindly, this defense does not last,” said the Ethereum Foundation on Tuesday, blindly signing “structural flaws” including the hacking of $1.4 billion in ByBit last year.

The “What You See You Sign” security feature aims to solve this problem and is being integrated into several self-protecting crypto wallets, including Ledger, Trezor, and Metamask.

The security feature comes despite significant improvements in recent years, with bad actors targeting the crypto industry with increasingly sophisticated hacks and scams.

North Korean-backed operatives have stolen more than $7 billion in funds since 2009 alone, with a significant portion of that from crypto protocols. The Bybit hack was the biggest crypto heist ever, compromising a third-party service provider and falsifying transaction signatures.

Trezor's chief technology officer, Tomasz Susanka, told Cointelegraph that attackers have been exploiting this relentlessly due to the lack of a widely available security feature to distinguish malicious contracts from legitimate transactions.

This problem has caused users to “unwittingly sign them and lose everything,” says Susanka, adding that the ClearSign feature “addresses this directly by making transactions human-readable before approval.”

The clear signature feature was introduced through the Ethereum Foundation's Trillion Dollar Security Initiative and was launched by Ledger in the open source ERC-7730 token standard.

The foundation says key elements of the ClearSign feature include “human-readable transaction statements” and “an independent, transparent record.”

It also includes a verification framework that allows auditors to verify those disclosures.

A host of crypto platforms support open signatures

Several other crypto wallets and Ethereum privacy and security platforms have contributed to the Clear signature feature, including Keycard, WalletConnect, Argot, Sourcify, Zama, ZKnox, and Fireblocks.

Susanka Trezor said it wants to implement the security feature before June 30.

“We're implementing this standard because it's the right thing to do for our users,” Susanka said before calling the clear signature feature “a critical security advance for our entire industry.”
