ERC-7730 Clear Signing Standard Ends Blind Crypto Transactions

ERC-7730 Clear Signing Standard Ends Blind Crypto Transactions

The Ethereum Foundation has introduced a new standard called ERC-7730, which aims to eliminate the longstanding problem of blind transactions in the crypto space. Developed by the Clear Signing working group in collaboration with Ledger, this standard replaces the incomprehensible hex data that wallets typically display with clear, human-readable descriptions of what a transaction will actually do. This innovation targets phishing attacks that exploit users’ inability to understand cryptic transaction prompts, leading to significant financial losses.

Currently, when users interact with smart contracts—whether approving token spends, listing NFTs, or setting up DeFi positions—most wallets show raw calldata or partial ABI decodes that are unreadable to non-developers. This gap between the displayed information and actual transaction intent is a primary vector for phishing scams, where malicious dApps trick users into signing draining transactions. Ledger has noted that blind signing is among the top causes of major user losses in hardware wallet incidents.

ERC-7730 comprises three key components. First, a unified JSON-based description format allows dApp developers to annotate their contracts with plain-language explanations of each function and parameter. Second, a public registry stores these descriptions, versioned and linked to specific contract addresses, enabling wallets to retrieve the relevant metadata at signing time. Third, an independent verification and auditing layer lets third parties review and certify the accuracy of descriptions, creating a trust chain from developer intent to wallet display.

Importantly, Clear Signing does not alter how transactions are structured, broadcast, or settled on-chain. Existing smart contracts, Layer 2 networks, and DeFi protocols require no modifications. Instead, the improvement lies entirely in the wallet presentation layer. Users will now see messages like ‘Approve Uniswap to spend up to 500 USDC from your wallet’ instead of hex strings, making it easy to verify intent before approving.

This standard arrives as wallet-level phishing and approval scams continue to plague retail users, even as protocol exploits become rarer. Recent incidents, such as the CoW DAO domain hijacking where users were tricked into signing malicious transactions on a phishing site, highlight the vulnerability Clear Signing addresses. Binance reported intercepting 22.9 million phishing attempts in Q1 2026 alone, underscoring the urgent need for legible transaction prompts. Clear Signing is part of Ethereum’s broader effort to enhance safety and accessibility without waiting for protocol-level changes.
