Ethereum Foundation Launches Clear Signing Standard to End Blind Transaction Approvals
A new joint initiative aims to protect users from billions in losses by eliminating blind signing vulnerabilities in Ethereum transaction approvals.

An Ethereum Working Group, including the Ethereum Foundation’s Trillion Dollar Security Initiative, wallet developers, and security firms, launched Clear Signing—an open standard designed to end blind signing vulnerabilities in Ethereum transaction approvals. Blind signing has caused billions in user losses, notably in the Bybit hack. Clear Signing requires explicit user confirmation of transaction details before approval to improve safety.
The Ethereum Foundation, in collaboration with wallet developers and security firms as part of its Trillion Dollar Security Initiative, has introduced Clear Signing, an open standard designed to improve the safety of transaction approvals on the Ethereum blockchain. This new protocol specifically targets the longstanding issue of blind signing—where users unknowingly approve transactions without full context—which has been linked to significant user losses, including the high-profile Bybit hack.
Blind signing poses serious risks by allowing malicious actors to exploit users’ wallets, often leading to irreversible theft of funds. Clear Signing addresses this by mandating explicit, transparent confirmations of transaction details before approval, effectively eliminating ambiguous or unseen consent. The initiative represents a collaborative effort, unifying industry stakeholders to raise security standards and restore user trust in decentralized finance operations.
By standardizing secure transaction signing, Clear Signing not only patches a critical security weakness but also aims to reduce the incidence of costly hacks and unauthorized transfers. Users and developers can adopt this open protocol to enhance their wallet interfaces and smart contract interactions, increasing clarity and control over transaction approvals. The timeline for widespread integration will depend on community adoption, but the Ethereum Foundation anticipates rapid uptake due to its direct impact on protecting user assets.
As the Ethereum ecosystem continues to grow, Clear Signing sets a precedent for proactive, systemic defenses against fraud. For users, a key checklist before approving transactions now includes verifying compliance with Clear Signing standards, thus mitigating risks associated with implicit consent. This initiative exemplifies how coordinated security improvements can safeguard the network’s integrity and long-term viability.
