- ERC-7730 lets wallets display readable transaction details, replacing confusing hexadecimal data during approvals.
- Firms including Ledger, MetaMask, Trezor, and Fireblocks joined the rollout to improve wallet transaction security.
- Ethereum Foundation said blind signing contributed to billions in losses, driving broader security upgrades under its Trillion Dollar Security effort.
The Ethereum Foundation has launched the “Clear Signing” open standard, introducing human-readable transaction approvals designed to reduce blind signing risks across the Ethereum ecosystem. The framework replaces unreadable hexadecimal transaction data with plain-language prompts that explain what users are approving before they sign wallet transactions.
New Standard Targets Blind Signing Risks
According to the Ethereum Foundation, blind signing remains one of the ecosystem’s largest security weaknesses. Many wallet interfaces still display raw transaction bytes or unclear prompts, leaving users unable to verify transaction intent before approval.
The new framework introduces ERC-7730, an open standard allowing protocols to describe transaction actions in readable text. Instead of approving opaque calldata, users can now see transaction details such as asset amounts, receiving addresses, and expected outcomes.
For example, a decentralized exchange transaction could display a message showing a swap of 1,000 USDC for ETH on Uniswap rather than a hexadecimal string.
The initiative does not change Ethereum’s core transaction infrastructure. Instead, it adds a verification and interpretation layer that wallets can use to convert technical data into readable descriptions.
The Ethereum Foundation described the upgrade as a major security and user experience improvement for transaction signing.
Major Wallet Firms Join Initiative
Several major crypto infrastructure firms contributed to the Clear Signing rollout, including Ledger, Trezor, MetaMask, WalletConnect, Fireblocks, Sourcify, Cyfrin, Zama, and ZKnox.
The initiative also introduces ERC-8176, an attestation framework allowing auditors and security providers to verify descriptor integrity before wallets display transaction information.
Ledger previously developed early versions of clear signing technology internally before contributing to the ERC-7730 standardization process. Trezor chief technology officer Tomáš Sušánka said attackers have repeatedly exploited blind signing because users could not distinguish malicious smart contracts from legitimate transactions.
The framework also includes a neutral descriptor registry that remains open and permissionless. Protocol developers, auditors, and researchers can publish transaction descriptors, while wallet providers independently choose which sources they trust.
Ethereum Expands Security Infrastructure
The Clear Signing initiative operates under the Ethereum Foundation’s Trillion Dollar Security effort. The rollout comes after several major phishing attacks and wallet-draining exploits across decentralized finance markets.
The Ethereum Foundation stated that blind signing contributed to billions in ecosystem losses, including the Bybit exploit last year. Developers involved in the initiative said broader wallet adoption will determine the framework’s long-term effectiveness.
Several participating wallet providers are expected to begin integrating the standard throughout 2026 as Ethereum continues expanding into tokenized finance and institutional blockchain infrastructure.
