Ethereum’s new ERC-7730 Clear Signing standard replaces hex nonsense in wallet claims with human-readable and auditable transaction summaries to reduce phishing and blind signing losses.
summary
- The Clear Signature Working Group of the Ethereum Foundation and Ledger co-designed ERC‑7730, a standard that turns today’s crypto-wallet call data into plain-language transaction summaries.
- Clear Signing uses a JSON description format, a public ledger linked to contract addresses, and external audits so wallets can show accurate WYSIWYS intent without changing the chain logic.
- This push comes at a time when phishing and consent scams are outpacing protocol breaches; Incidents like the CoW DAO domain hijack and Binance’s 22.9 million blocked phishing attempts show how important clear claims are.
The Ethereum Foundation’s Clear Signature Working Group has published a new open standard designed to replace the encrypted, machine-readable hex data that wallets currently display when users are asked to approve a transaction, according to an official. Ethereum Foundation blog post. Based on the ERC-7730 specification, Clear Signing standardizes how transaction intent is described, displayed, and verified across wallets, with the goal of giving users a clear-language summary of what will actually happen on-chain before they click consent.
ERC-7730 and unreadable end-of-transaction claims
The problem of erasing signature addresses is one of the oldest and most exploited user experience failures in cryptocurrencies. When a user interacts with a smart contract — whether agreeing to spend a token, listing an NFT, or authorizing a DeFi center — most wallets today expose raw connection data or partial ABI decryption that cannot be read by anyone who is not a developer. This gap between what the screen shows and what the transaction actually does is the underlying mechanism behind a large portion of phishing attacks, where malicious dApps present a benign-looking interface while the underlying transaction drains the wallet. Ledger, who co-developed ERC-7730 alongside the Ethereum Foundation Working Group, described the standard as a direct response to this attack surface, noting that “blind signing” was one of the top two causes of significant user losses in hardware wallet incidents.
The Clear Signing architecture consists of three components. First, a unified JSON-based description format tied to ERC-7730 that DApp developers use to annotate their contracts with human-readable explanations for every function call and parameter. Second, a public registry where these descriptions are stored and issued and linked to published contract addresses so that wallets can pull the relevant metadata at signing time. Third, an independent verification and auditing layer where third parties can review and certify the accuracy of contract descriptions, creating a chain of trust between the dapp developer’s intent and what the wallet ultimately displays.
WYSIWYS: What changes for users and what stays the same
The standard is explicitly designed not to break. Clear signing does not change how transactions are structured, broadcast, or settled on-chain, meaning that existing smart contracts, layer 2 networks, and DeFi protocols do not require any changes to take advantage of it. The improvement lies entirely in the wallet’s presentation layer: instead of showing a raw hex string or a partial dump of parameters, a clear signature-compatible wallet will display something like “Uniswap approved to spend up to $500 from your wallet” or “CryptoPunk #4156 is listed for sale at 40 ETH on OpenSea” – an accurate, fact-checked, human-readable description derived from the ERC-7730 registry entry for this contract.
For the broader Ethereum security ecosystem, Clear Signing arrives at a moment when wallet-level phishing and approval scams remain the dominant attack vector for retail users even as protocol-level exploits are difficult to implement on mature, audited contracts. Modern crypto.news The story of the CoW DAO domain hijacking incident — where attackers redirected users to a phishing site for 4.5 hours and urged them to sign malicious transactions — precisely illustrates the failure mode that Clear Signing was designed to mitigate: users who could read what they were signing would have a much better chance of detecting the anomaly before agreeing to an exchange. In parallel, A crypto.news The story of Glamsterdam devnet’s progress for Ethereum shows how the organization is simultaneously advancing implementation layer upgrades and driving refactoring, with Clear Signing aligning with a broader push to make Ethereum more secure and accessible at every layer of the stack without waiting for changes to be propagated at the protocol level. your crypto.news According to the AI-powered cryptocurrency scam story, Binance’s security data shows that 22.9 million phishing attempts were intercepted in the first quarter of 2026 alone — a volume that underscores why making transaction approval legible for ordinary users is no longer a fine-tuned user experience but a security necessity.
