Ethereum Introduces Clear Signing to Combat Blind Signing Risks

The Ethereum community has unveiled Clear Signing, a new security feature designed to eliminate blind signing—a practice that has long exposed users to significant risks. Announced as part of the Ethereum Foundation’s Trillion Dollar Security Initiative, Clear Signing makes transactions human-readable before approval, replacing cryptic hex data with transparent descriptions.

Blind signing, where users approve transactions without fully understanding the details, has led to billions of dollars in losses. The Ethereum Foundation highlighted the $1.4 billion Bybit hack in 2025, where attackers exploited transaction signatures, as a key example of the issue. Calling blind signing a “structural flaw,” the foundation emphasized the urgency of implementing solutions like Clear Signing to protect users.

The new feature uses the open-source ERC-7730 token standard and incorporates key elements such as human-readable transaction descriptions and a descriptor registry. It also includes an attestation framework, enabling auditors to verify the accuracy of these descriptors. Major wallet providers like Ledger, Trezor, and MetaMask are integrating the feature, which aims to provide an additional layer of security for self-custody users.

Trezor CTO Tomáš Sušánka explained that attackers have exploited the lack of transparency in transaction details to deceive users into signing malicious contracts. “This issue has led users to unknowingly sign them and lose everything,” Sušánka told Cointelegraph. He described Clear Signing as a “critical security advancement” and confirmed that Trezor plans to roll out the feature by June 30.

Clear Signing arrives at a time when crypto-related hacks and scams are becoming increasingly sophisticated. North Korean state-sponsored groups alone have reportedly stolen over $7 billion since 2009, with a significant portion coming from compromised crypto platforms. The Bybit hack remains one of the largest, underscoring the need for enhanced security measures across the industry.

Beyond wallets like Ledger and Trezor, several other platforms have contributed to the development of Clear Signing, including WalletConnect, Fireblocks, and Zama. The collective effort highlights a broader industry push toward making decentralized finance (DeFi) safer for everyday users.

With Clear Signing, Ethereum aims to set a new standard for transaction security, reducing the risks associated with blind signing and paving the way for more secure interactions on the blockchain.
