The Ethereum Working Group, a coalition including wallet developers, security firms, and the Ethereum Foundation’s Trillion Dollar Security Initiative, has officially launched an open standard designed to eliminate blind signing. This major user experience (UX) and security upgrade aims to make human-readable transactions the default across the Ethereum ecosystem.
The initiative builds upon existing work, specifically the ERC-7730 standard pioneered by Ledger. It introduces a comprehensive framework that combines a descriptor schema, a neutral registry, a flexible attestation model, and developer libraries. Together, these tools allow transaction data to be verified and clearly described before a user ever confirms a sign request.
High Cost of Hexadecimal Transactions
For years, the lack of transaction legibility has been a primary vulnerability in the ecosystem, contributing to billions of dollars in losses. Blind signing occurs when a user is forced to approve a transaction represented only by a string of hexadecimal code, which requires significant technical expertise to interpret.
The 2025 Bybit hack is a stark example of the dangers of this status quo. In that instance, a single contract change that was not legible on a hardware device resulted in a $1.5 billion loss. By implementing ERC-7730, the working group aims to replace these confusing strings with plain language, showing exactly who the user is interacting with, what their intent is, and what parameters are being executed.
“Blind signing has been responsible for billions in user losses. When transaction data appears as hexadecimal code, users approve transactions they don’t understand. Attackers exploit this relentlessly. Malicious smart contracts are indistinguishable from legitimate transactions, users unknowingly sign them, and lose everything. Clear Signing directly addresses this by making transactions human-readable before approval,” explained Tomáš Sušánka, CTO of Trezor.

Four-Pillar Solution for Clear Signing
To resolve the fragmentation of proprietary solutions, the working group has introduced a four-part infrastructure:
- Updated ERC-7730 (an open standard for describing transactions in human-readable formats);
- Decentralized registry (an off-chain registry neutrally hosted by the Ethereum Foundation for distributing these descriptors);
- Integrity and attestation framework (ERC-8176 and the Ethereum Attestation Service (EAS) allows independent auditors to verify descriptors while letting wallets define their own trust policies);
- Developer SDKs (tools for wallet integration and auditor verification workflows in languages such as React and Rust).
Ecosystem-Wide Collaboration
The effort is supported by a broad spectrum of industry leaders. Contributors include hardware and software wallets such as Ledger, Trezor, MetaMask, and Zknox; infrastructure providers like Fireblocks and Zama; and security firms such as Cyfrin. The Ethereum Foundation serves as a neutral steward for the project.
According to the information received by CoinScreamer, Trezor is planning to implement the Ethereum Foundation’s Clear Signing standard across its products over the coming months. ” We’re targeting the beginning of Q2 2026 for Clear Signing transaction decoding, converting complex hex data into a readable format, and the end of Q2 2026 for full human-readable signing implementation. We’re implementing this standard because it’s the right thing to do for our users. We hope that everyone in the industry implements this standard as well so the whole web3 ecosystem becomes safer for all users,” stated its CTO.
The working group is calling for immediate action across the industry: protocols are urged to provide human-readable descriptions, auditors are encouraged to attest to transaction behaviors, and wallet developers are expected to integrate these new signing experiences. The project’s ultimate goal is to ensure that users never sign a transaction they cannot meaningfully interpret.
