Ethereum launches Clear Signing (ERC-7730) for readable txns

Ethereum launched Clear Signing, a standard under the ERC-7730 identifier, that lets compatible wallets show human-readable summaries of transactions by consulting a public registry at Clearsigning.org. The change does not require modifying or redeploying existing smart contracts.

ERC-7730 defines a format for contract descriptors, which are metadata files that describe what a contract function will do in plain language. When a user initiates a transaction, a wallet that supports the standard queries the registry for a matching descriptor and, if one is found, renders a summary such as you are swapping 1.5 ETH for 3,200 USDC on Uniswap v4 instead of showing a raw function signature and encoded parameters.

Descriptors act as an overlay on top of live contracts, so the standard can be applied to contracts already deployed on mainnet. Anyone may submit a descriptor to the Clearsigning.org registry; submissions are subject to independent review before inclusion in the public index.

A consortium of wallet providers and security firms is backing Clear Signing. Participants include Ledger, Trezor, MetaMask and WalletConnect, covering hardware wallets, browser-based extensions and wallet infrastructure. WalletConnect’s involvement could help propagate descriptors to decentralized applications that rely on its connection protocol.

The initiative targets blind signing, a frequent attack vector in which users approve transactions without understanding the encoded actions. Malicious front ends and contracts have used opaque transaction data to obtain token approvals or transfer assets. The Bybit hack is a recent example involving signing-related exploitation, and Binance reported blocking 22.9 million phishing attempts in the first quarter of 2026.

Adoption of ERC-7730 is voluntary. The breadth of registry entries and whether major decentralized finance platforms publish descriptors for commonly used functions will determine how often users encounter readable summaries in wallets. Wallets that implement the standard can present verified, human-readable descriptions in real time while the underlying contracts remain unchanged on-chain.
