The Ethereum Foundation has introduced new infrastructure for Clear Signing, a security approach intended to replace unreadable transaction data with human-readable prompts. The initiative also includes support for ERC-7730, a common standard for transaction descriptions, and the launch of a public registry for contract descriptors reviewed by security experts.
The nonprofit said Clear Signing is designed to make blockchain transactions easier for users to verify before approval. The system focuses on replacing confusing hexadecimal prompts with readable transaction descriptions that explain what a wallet interaction actually does.
Rather than showing raw calldata, wallets using Clear Signing can present direct explanations such as a token swap, NFT transfer, or staking interaction. The goal is to reduce confusion during approvals, particularly for less technical users interacting with decentralized finance applications.
As part of the rollout, the Ethereum Foundation confirmed support for ERC-7730, an open standard originally proposed by Ledger in 2024. The format is intended to create a shared structure for transaction descriptions so wallets can display the same information consistently across applications.
The Ethereum Foundation said Clear Signing improves the final verification layer between users and blockchain applications while preserving Ethereum’s open architecture.
The Ethereum Foundation also announced a public registry for contract descriptors, alongside tooling libraries intended to help wallets and developers integrate the feature more efficiently. The registry allows contributors to submit transaction descriptions that can later be reviewed and verified by independent security experts.
The registry operates through clearsigning.org. Because transaction descriptors remain off-chain, the Ethereum Foundation said the approach supports existing smart contracts. Wallet providers can retrieve verified descriptions from the registry and display them in user interfaces.
The initiative has drawn contributions from multiple crypto firms and infrastructure providers, including MetaMask, WalletConnect, Fireblocks, and Trezor.
Clear Signing targets blind signing, which the Ethereum Foundation described as one of the largest security weaknesses in crypto wallets. It said attackers often exploit unreadable transaction prompts to trick users into approving malicious smart contract actions. The organization pointed to heightened concerns following several high-profile exploits over the past two years, including the $1.4 billion Bybit attack linked to fraudulent transaction approvals.
The release aligns with the Ethereum Foundation’s broader security strategy. Over recent months, the organization said it increased research into post-quantum cryptography, expanded audit funding programs, and reorganized parts of its protocol leadership structure.
Premium gym chains are entering a “golden era” that is ending or already in decline, as rising operating costs collide with shifting consumer preferences toward more flexible, community-based ways to exercise. Long-term memberships are shrinking, margins are pressured by higher rents and facility expenses, and competition from smaller, more personalized…
