- The Ethereum Foundation has introduced ERC-7730, a new security standard designed to eliminate “blind signing” by translating complex hex data into human-readable text.
- Major wallet providers including MetaMask, Trezor, and Ledger have committed to integrating the standard to protect users from malicious transaction approvals.
- The initiative is part of the Foundation’s broader Trillion Dollar Security Initiative, featuring a public registry for verified transaction descriptions.
The Ethereum Foundation officially launched a new open security standard on May 12, aiming to eradicate the “blind signing” vulnerability that has resulted in billions of dollars in lost assets. The framework, known as Clear Signing, is built upon the ERC-7730 technical specification. It provides a unified format that converts raw, hexadecimal calldata into structured, plain-English summaries, allowing users to verify the exact intent of a transaction—such as token approvals or DeFi swaps—before clicking approve.
For years, the discrepancy between what a decentralized application (dApp) interface displays and the machine-readable code shown in a wallet has been a primary vector for phishing and wallet-draining attacks. High-profile exploits, including the recent $1.4 billion breach of the Bybit exchange, have been attributed to signers unknowingly authorizing malicious transactions due to unreadable data prompts. The new standard seeks to establish a “What You See Is What You Sign” (WYSIWYS) environment across the Ethereum ecosystem.
The technical core of the initiative, ERC-7730, utilizes a shared JSON description format and a public registry. This registry allows independent security researchers and auditors to verify and attest to the accuracy of transaction descriptions. Because the standard operates at the wallet presentation layer, it does not require changes to existing smart contracts or underlying blockchain architecture, significantly lowering the barrier for developer adoption.
“Approving a transaction is meant to be the last line of defense when exercising control over what happens to your assets on the blockchain,” the Ethereum Foundation stated during the rollout. “When it is done blindly, that defense does not hold.”
A broad coalition of industry leaders has already signaled support for the framework. In addition to MetaMask and Trezor, early adopters include Ledger, Fireblocks, WalletConnect, and Zama. Trezor has specifically indicated it plans to complete its implementation of the Clear Signing feature by June 30, 2026. While the standard does not eliminate all phishing risks, it forces attackers to present their intent in clear language, making malicious interactions far easier for users to identify.
