Ethereum community launches security feature to end blind signing

Crypto platforms Ledger, Trezor, MetaMask, Keycard, WalletConnect, Argot and Fireblocks are among the earliest adopters and contributors to Clear Signing, aimed at ending “blind signing.”

The Ethereum community has introduced Clear Signing, a security feature that ensures users can clearly understand transaction details before signing, replacing unreadable hex data and reducing risks from blind signing attacks.

“Approving a transaction is meant to be the last line of defense when exercising control over what happens to your assets on the blockchain. When it is done blindly, that defense does not hold,” the Ethereum Foundation said on Tuesday, calling blind signing a “structural flaw” that has contributed to billions of dollars in losses, including the $1.4 billion Bybit hack last year.

The “What You See Is What You Sign” security feature aims to address this issue and is being integrated by several self-custody crypto wallets, including Ledger, Trezor and MetaMask.
