Ethereum Foundation Rolls Out Clear Signing

The Ethereum Foundation announced on Tuesday the rollout of support for Clear Signing, an open standard designed to replace opaque transaction data in wallets with human-readable descriptions, addressing longstanding risks from blind signing in the Ethereum ecosystem.

Blind signing, where users approve transactions displaying raw hexadecimal code or generic labels, has exposed cryptocurrency users to phishing attacks, wallet drains, and malicious smart contracts. The Foundation highlighted incidents like the Bybit hack, where attackers exploited unclear approvals to steal funds, as examples of the vulnerability. Clear Signing introduces a "What You See Is What You Sign" model, enabling wallets to display prompts such as "You are swapping 100 USDC for 0.05 ETH on Uniswap" or "You are granting token access to this contract."

At the core of the initiative is ERC7730, a standard originally proposed by Ledger, which provides a shared JSON-based format for structured transaction descriptions. These off-chain descriptors link to contract addresses, allowing wallets to fetch and present clear details without requiring changes to existing smart contracts or blockchain logic. The...
