Ethereum Foundation launches "Clear Signing" standard to kill blind transaction approvals
The Ethereum Foundation released ERC-7730, an open "Clear Signing" standard that gives wallet users human-readable descriptions of transactions to eliminate blind signing approvals.
An Ethereum Working Group backed by the Foundation's Trillion Dollar Security Initiative has released an open standard, ERC-7730, aimed at showing wallet users a human-readable description of what they're actually signing.
On May 12, 2026, the Ethereum Foundation announced Clear Signing, a standard and supporting infrastructure meant to end "blind signing" — the common situation where a user approves a transaction presented in low-level, machine-readable data they can't meaningfully interpret. The Foundation frames the transaction approval as "the last line of defense" over on-chain assets and argues that when it's done blindly, that defense fails. Its stated goal is "What You See Is What You Sign" (WYSIWYS) as the ecosystem default.
The system has four moving parts, per the Foundation: a shared descriptor format (ERC-7730) for human-readable transaction descriptions; a registry to store and distribute those descriptors; a verification layer where independent reviewers attest to a descriptor's accuracy; and tooling — including Rust and TypeScript libraries funded through the 1TS initiative — to help wallets and developers adopt it. Crucially, descriptors travel alongside the transaction rather than being embedded in it, which the Foundation says lets both existing and new applications be covered while still allowing accuracy to be independently verified. Anyone can submit a descriptor; wallets choose which attestation sources to trust.
The Foundation's 1TS initiative says it will host the registry infrastructure as a "credibly neutral steward," with adoption pushed through clearsigning.org. It ties the effort to real losses, citing blind signing as a structural factor in "billions" of user losses "including the Bybit hack," though the post gives no specific dollar figure or breakdown for that claim.
The announcement credits Ledger with initiating ERC-7730 and the early tooling. It lists contributors including ZKnox, Sourcify, Cyfrin, Zama, WalletConnect, Fireblocks, Trezor, Keycard, MetaMask, Argot, and independent developers.

The real-world read
This is the Ethereum Foundation's own announcement of its own initiative — a primary source, but not a neutral one, and every figure here traces to a single post. The "billions in user losses, including the Bybit hack" line is asserted without a number or a citation; the Bybit breach is widely reported as a signing-interface deception, so the framing fits, but the Foundation is quantifying the problem its own product solves. Note also what's not claimed: no wallet is announced as having shipped Clear Signing by default, and the post "encourages" adoption rather than reporting it — this is a launch of a standard and a registry, not evidence anyone is using it yet. The attestation model also leaves the hard question open: a descriptor is only as trustworthy as the reviewer a wallet chooses to trust, and who those attesters are, and how they're vetted, isn't spelled out.
Opinion, and whose
The Ethereum Foundation argues Clear Signing "must be the default" for institutions to hold trillions on Ethereum, and casts WYSIWYS as necessary for "the next wave of users and institutional adoption." That is the Foundation's position and forecast, not an established outcome.
