The Ethereum Foundation, in partnership with a coalition of wallet developers and security firms, launched an open standard on May 12, 2026 designed to eliminate one of the most persistent and costly vulnerabilities in the crypto system: blind signing.
The initiative, called Clear Signing, replaces the opaque, machine-readable transaction data that users have long been asked to approve – often without any meaningful ability to understand what they’re actually authorizing – with clear, human-readable descriptions of exactly what a transaction will do.
The announcement, published directly on the Ethereum Foundation blog by Hester Bruikman, marks a significant moment in the Foundation’s Trillion Dollar Security Initiative: the first industry-wide, standards-based solution to a problem that has cost crypto users billions of dollars.
what’s Blind Signing and Why Does It Matter?
Every time a user interacts with a decentralized application on Ethereum – swapping tokens, providing liquidity, minting an NFT, or approving a smart contract – they’re asked to sign a transaction. In most cases, what gets displayed to the user before they tap “Confirm” is a string of hexadecimal data or a series of technical fields that offer little to no meaningful information about what will actually happen to their funds.
This is blind signing. And it’s the final step in the vast majority of significant crypto theft events.
The Bybit hack – one of the largest single crypto thefts in history – followed this exact pattern. So did countless phishing campaigns that have drained retail and institutional wallets alike. The code may be legitimate or compromised, but if the user can’t read what they’re about to approve, the approval itself becomes a single point of catastrophic failure.
“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 wrote in its announcement. “When it’s done blindly, that defense doesn’t hold.”
How Clear Signing Works
The technical foundation for Clear Signing is built on two Ethereum Request for Comment standards: ERC-7730 and ERC-8176.
ERC-7730, initially developed by hardware wallet company Ledger, defines a shared format for transaction descriptors – structured, human-readable explanations of what a given smart contract call will do. These descriptors are stored in an open registry where anyone can contribute, and where their accuracy is verified through independent reviews and attestations from security experts.
ERC-8176 extends the standard to cover additional interaction patterns and cross-chain use cases. A second major version of ERC-7730, released in April 2026, expanded coverage to software wallets and confidential token primitives.
When a user is about to sign a transaction, a wallet setting up Clear Signing pulls the relevant descriptor from the registry and presents the information in plain language: what assets are being transferred, to where, under what conditions. The user sees what they’re actually signing – not a hex string.
The Ethereum Foundation is hosting the registry infrastructure and being what the announcement calls a “credibly neutral steward,” ensuring that no single commercial entity controls the standard.
Who Built It and who’s Adopting It
The working group behind Clear Signing includes some of the most prominent names in Ethereum security and wallet development. Contributors include MetaMask, WalletConnect, Fireblocks, Trezor, Keycard, and Argot, alongside security firms ZKnox, Sourcify, Cyfrin, and Zama.
The Foundation gave explicit credit to Ledger for starting ERC-7730 and doing early tooling work, describing the overall effort as a deliberately multi-party coordination rather than a top-down mandate.
Tooling for developers – including Rust and TypeScript libraries – is available through clearsigning.org, which will serve as the central hub for wallet adoption and developer integration guidance.
The initiative addresses a longstanding complaint from security researchers: that the Ethereum system had developed increasingly sophisticated smart contracts while the user-facing approval layer remained fundamentally broken for anyone without deep technical expertise.
The Scale of the Problem
Phishing attacks and transaction approval exploits have collectively drained billions of dollars from Ethereum wallets over the past several years. The Foundation explicitly tied the Clear Signing initiative to the $1 trillion security goal, arguing that if Ethereum is to mature into infrastructure for global finance, “What You See Is What You Sign” can’t remain an aspiration – it must be the technical default.
The April 2026 release of ERC-7730 V2 was the last major technical prerequisite. With the standard now ready and the registry operational, the implementation burden shifts to wallet developers. The Foundation said it’s actively encouraging adoption and will support teams through the integration process.
What This Means for Users
In the short term, Clear Signing only helps users whose wallets have set up the standard. For those wallets, the approval screen for any transaction whose descriptor exists in the registry will display plain-language information rather than raw data.
Over time, as more wallets adopt the standard and more application developers contribute descriptors, blind signing will become a rarity rather than the default. The goal, as the Foundation framed it, is for Clear Signing to become the assumed baseline for every Ethereum interaction.
For institutional users – particularly custodians, trading desks, and funds that move significant capital through Ethereum – the shift is especially meaningful. Fireblocks’ participation in the working group reflects the institutional demand for a signing standard that can meet the verification requirements of professional risk management.
FAQ
what’s Clear Signing on Ethereum? Clear Signing is an open standard that replaces the opaque, machine-readable data users currently see when approving crypto transactions with human-readable explanations of exactly what a transaction will do. It uses ERC-7730 and ERC-8176 standards and is maintained in an open registry by the Ethereum Foundation.
How does Clear Signing prevent phishing? By showing users exactly what they’re signing – which assets move, to which address, under what conditions – Clear Signing removes the ambiguity that phishing attacks exploit. Users can verify the transaction intent before approving, rather than signing data they can’t interpret.
Which wallets support Clear Signing? MetaMask, WalletConnect, Fireblocks, Trezor, Keycard, and Argot are among the early contributors to the working group. Full adoption will roll out as teams integrate the tooling available at clearsigning.org.
