Ethereum Foundation Launches Clear Signing Standard to Replace Blind Approvals

The Ethereum Foundation launches Clear Signing today, an open standard designed to eliminate the “blind signing” vulnerability that has cost crypto users billions in phishing losses. The initiative marks a fundamental shift in how digital wallets communicate with humans, turning unreadable hexadecimal strings into clear, actionable data before a user authorizes a transaction.

The Foundation debuted the standard Tuesday, as part of a coordinated effort with the industry’s largest wallet manufacturers and service providers. Clear Signing utilized the ERC-7730 framework to define a structured format for describing what a smart contract actually intends to do. Wallet software can now pull verified, human-readable descriptions from a public registry, allowing a trader to see exactly how much they are spending and which assets are moving before they click “approve.”

Ledger pioneered the initial concept and developed the core of ERC-7730 before transferring stewardship to the Ethereum Foundation to ensure the project remained a neutral, public good. A working group including Trezor, MetaMask, WalletConnect, and Fireblocks collaborated to refine the technical specifications. The Foundation now maintains the central registry at clearsigning.org and provided the necessary tooling for developers to register their contracts. 

Blind signing remained a persistent security hole for a decade, as users often approved transactions they couldn’t understand. Phishing attacks frequently exploited the gap by tricking victims into signing malicious “setApprovalForAll” or “permit” functions disguised as routine claims or mints. “Blind signing has been a persistent security weakness that we can no longer ignore,” a Foundation lead noted, characterizing the new standard as the “last line of defense” for everyday users.

The implementation arrived at a critical moment as smart contract wallets and AI-powered agents gained mainstream adoption. Autonomous systems and human users alike required more transparent ways to verify contract intent as interactions grew in frequency and complexity. Major wallet providers committed to immediate integration. Ledger and Trezor planned firmware updates to support the readable format, while MetaMask and WalletConnect began rolling out browser and mobile implementations.

The Foundation positioned the initiative as a central pillar of its “Trillion Dollar Security Initiative,” a broader project focused on practical infrastructure improvements that protect user capital. Developers across the ecosystem were encouraged to submit descriptors for their protocols to the clearsigning.org registry immediately. “By making intent transparent and verifiable, we’re giving users the tools to catch malicious activity before it’s too late,” the Foundation added in its public briefing.

Chain Street’s Take

Clear Signing is the death of the “fingers crossed” era of crypto transactions. For years, clicking “confirm” on a wallet was an act of blind faith that required users to hope the DApp they were using hadn’t been hijacked. By mandating a human-readable standard via ERC-7730, the Ethereum Foundation is finally treating the user interface as a security feature rather than an afterthought. It’s a massive win for retail safety. If MetaMask and Ledger follow through on their integration promises, the success rate of simple phishing scams will likely fall off a cliff. The challenge now is on developers: if they don’t register their contracts at clearsigning.org, they’ll soon find their users rightfully terrified to sign a transaction that still looks like a pile of gibberish.
