Clear Signing is best understood as a transaction-understanding layer for Ethereum. Announced by an Ethereum Working Group of wallet developers, security firms, and the Ethereum Foundation’s Trillion Dollar Security Initiative, it is designed to address blind signing: approving transaction data a user cannot meaningfully read before authorizing it [17]. Its technical core is ERC-7730, a draft Structured Data Clear Signing Format that defines JSON metadata for displaying smart-contract calls and typed messages to humans before signature [

11].
Ethereum transactions often involve smart-contract calls, not just simple token transfers. That makes wallet prompts harder to explain: ethereum.org says hardware wallets may show raw hex calldata, while software wallets usually decode fields only when they recognize the contract [5]. When the protocol is new, the app is compromised, or the device is offline, users can still end up signing blind [

The Ethereum Foundation frames this as more than a usability problem. Its Clear Signing announcement describes blind signing as a structural flaw that has contributed to billions in user losses, including the Bybit hack [17]. The goal is to make the approval screen show the intent of a transaction before the user confirms it [
17].
ERC-7730 is not a new transaction type and does not change what happens on-chain. It is a descriptor format: extra metadata that tells a wallet how to turn contract calls and EIP-712 typed messages into a readable display [2][
4].
Ledger’s technical specification describes an ERC-7730 file as including binding information such as contract address, chain ID, and ABI, plus metadata and display rules that determine how transaction data is formatted for the user [1]. In practice, the descriptor acts like a translation layer between low-level calldata and the wallet screen.
A simplified flow looks like this:
For users, the visible change is straightforward: instead of raw calldata or a vague signing prompt, supported wallets and devices can show understandable transaction details. Ledger describes Clear Signing as translating complex smart-contract data into understandable transaction details, including on a Ledger device’s secure screen [16][
18].
Clear Signing is only as reliable as the descriptor a wallet uses. The descriptor defines how a contract call or typed message is interpreted for display, so it becomes part of the security model [1][
2].
| Component | What it does | Why it matters |
|---|---|---|
| ERC-7730 descriptor | Describes how to display a smart-contract call or typed message in human-readable form [ | It determines what the user sees before signing [ |
| Registry | Helps wallets find descriptors for contracts and chains; the Ethereum Foundation says its Trillion Dollar Security Initiative is acting as a credibly neutral steward of the Clear Signing registry [ | Without broad registry coverage, many contracts may still fall back to unreadable or partially decoded prompts [ |
| Audits and attestations | Launch coverage describes auditor attestations and cryptographic fingerprints as part of the surrounding Clear Signing infrastructure [ | They are meant to give wallets and users confidence that the descriptor accurately represents the transaction being signed [ |
This is the key trade-off. A registry makes descriptors discoverable, but it also introduces curation and trust questions. A descriptor audit can reduce the risk of a misleading display, but it does not automatically make every contract safe or every wallet prompt complete. Public materials describe the direction of the registry and attestation model, but they do not fully spell out every governance, dispute, or stale-descriptor handling detail [8][
17].
The official Ethereum Foundation announcement says the launch came from an Ethereum Working Group made up of wallet developers, security firms, and the Foundation’s Trillion Dollar Security Initiative [17]. It does not, in the available excerpt, provide a complete official roster of every participant.
Ledger is the clearest named supporter in the available sources: it publishes ERC-7730 and Clear Signing technical documentation, promotes Clear Signing for Ledger devices, and says more than 15 popular service providers support Clear Signing and Transaction Check through Ledger Wallet [1][
2][
16][
18].
Third-party launch coverage reports that working-group members include Ledger, Trezor, MetaMask, WalletConnect, Cyfrin, and Fireblocks [8]. MetaMask support has also been reported separately in connection with a Ledger collaboration focused on Clear Signing [
26]. Because the official Ethereum Foundation material here names categories rather than a full list, those third-party names should be read as reported ecosystem participation rather than a complete canonical directory [
8][
17].
Clear Signing does not magically make every Ethereum interaction readable. Each supported contract call or typed message needs suitable metadata, and wallets need to support the standard [1][
2][
5]. ethereum.org’s explanation is blunt about the current gap: software wallets decode fields only when they recognize a contract, and users can still sign blind when they do not [
5].
Long-tail coverage is a known challenge. A proposal from Kampela, a builder of air-gapped hardware signing devices, argues that curated off-chain registries such as ERC-7730 can bring clear signing to well-known contracts but depend on third-party curation and may struggle to scale to the long tail of contracts deployed every day [6]. That is a critique from a proposed alternative design, not proof that ERC-7730 cannot scale, but it highlights the practical adoption problem: descriptors must exist, be discoverable, and stay accurate.
Clear Signing is easiest to understand when a wallet or device can fetch or receive updated descriptors through normal software channels. Ledger’s consumer material describes connecting a Ledger signer via Bluetooth or USB and showing clear transaction details on-device [16].
Fully air-gapped devices raise a tougher question: how does the signer receive, verify, and update descriptor data without trusting an online intermediary? ethereum.org notes that offline devices are one of the cases where users can still end up signing blind [5]. Kampela’s on-chain clear-signing proposal is explicitly aimed at making transactions human-readable and verifiable on constrained, air-gapped devices without trusted third parties, and it critiques off-chain registry approaches for their reliance on curation [
6].
That does not mean Clear Signing cannot work with hardware wallets. It means the strongest guarantees for fully air-gapped workflows are still less clear from the available public materials than the guarantees for connected wallet and hardware-wallet flows.
Ethereum Clear Signing is a serious attempt to replace blind approvals with readable intent. ERC-7730 supplies the descriptor format; registries make descriptors discoverable; audits and attestations help establish trust in what the wallet displays [1][
2][
8][
17].
The standard’s value will depend on adoption. If major wallets, hardware devices, protocols, registries, and auditors converge on reliable descriptors, users should see fewer opaque signing prompts. If coverage remains thin, especially for new contracts and air-gapped devices, blind signing will not disappear everywhere at once [5][
6].
