TLDR
- Ethereum Foundation added support for Clear Signing to improve wallet transaction safety.
- Clear Signing replaces unreadable transaction data with human-readable approval details.
- ERC-7730 will serve as the shared format for Ethereum transaction descriptions.
- The Foundation is supporting clearsigning.org as a registry for contract descriptors.
- Wallets can use verified descriptors to show users what a transaction will do.
The Ethereum Foundation has rolled out support for Clear Signing, a security framework designed to help users understand crypto transactions before approving them.
The effort is aimed at reducing risks linked to blind signing, a common wallet process where users approve transactions that display raw technical data instead of clear instructions. Security researchers have long warned that blind signing can expose users to phishing attacks, wallet drains and malicious smart contracts.
Clear Signing changes that experience by showing human-readable transaction details. Instead of displaying unreadable calldata, a wallet could show a message such as, “You are swapping 100 USDC for 0.05 ETH on Uniswap,” or “You are granting token access to this contract.”
The Ethereum Foundation said the goal is to support a “What You See Is What You Sign” model across wallets and decentralized applications. The organization is positioning itself as a neutral coordinator for adoption, standards and public tooling.
Clear Signing Targets Blind Signing Risks
Blind signing has become one of the most serious user-facing security problems in crypto. Many wallet approvals require users to trust an application without fully understanding what the transaction will do.
Attackers often exploit that gap by creating fake websites, malicious links or compromised applications that trick users into approving dangerous transactions. Once approved, those transactions can transfer funds, grant token permissions or expose wallets to future theft.
The Ethereum Foundation pointed to large attacks, including the Bybit hack, as examples of how blind signing can be abused. In that case, attackers reportedly used a malicious transaction approval process to steal funds.
Clear Signing does not remove all transaction risk, but it gives users clearer information before they approve. It also gives wallets a more consistent way to display transaction meaning across different apps and contracts.
The standard is especially relevant as Ethereum expands toward more mainstream and institutional users. Larger users often require clearer controls, audit trails and permission visibility before using blockchain applications at scale.
ERC-7730 Becomes Shared Format
The Ethereum Foundation named ERC-7730 as the shared format for structured transaction descriptions. The standard was originally proposed by Ledger and is designed to give wallets a common way to read and display transaction details.
The foundation is also supporting clearsigning.org, a public registry where contract descriptors can be submitted, reviewed and distributed. These descriptors explain what transactions do in human-readable form.
Developers can submit descriptors for their smart contracts. Independent security experts can review and attest to their correctness. Wallets can then use verified descriptions from the registry and show users clearer approval prompts.
The descriptors live off-chain, meaning Clear Signing can work with existing smart contracts without requiring those contracts to be redeployed. This makes the approach more practical for broad adoption across the current Ethereum ecosystem.
The Ethereum Foundation is also hosting tooling libraries to help wallets, developers and security teams integrate Clear Signing into their products.
Wallets and Developers Urged to Adopt
The success of Clear Signing depends on adoption across wallets, decentralized applications and security providers. The Ethereum Foundation encouraged developers to provide accurate descriptions for their transactions and asked security experts to review submissions.
Several ecosystem contributors have supported the work, including ZKnox, Sourcify, Cyfrin, Zama, WalletConnect, Fireblocks, Trezor, Keycard, MetaMask, Argot and independent developers.
The effort is part of a broader push by the Ethereum Foundation to improve security and user experience. The nonprofit recently created a Trillion Dollar Security initiative and launched a $1 million audit subsidy to help reduce the cost of security reviews.
The foundation has also increased research into privacy and post-quantum security, reflecting the growing need for stronger infrastructure as Ethereum handles larger financial activity.
