Following an attack in which a wallet drainer was introduced to a library used by many developers to connect to its devices, hardware wallet maker Ledger will prohibit blind signature for EVM decentralized applications (dapps) by June 2024. Ledger stated via a tweet that about $600,000 in crypto assets were taken during the attack.

It stated that impacted victims will be “made whole” and that “Blind Signing with Ledger devices will no longer be permitted by June 2024.”

Blind signing entails displaying raw smart contract signing data that computers can analyze but is unintelligible to a human reader. Ledger has previously argued for clear signature, a “what you see is what you sign” method in which smart contract signing is processed in a human-readable manner.

Ledger noted in its release that its decision to phase out blind signing will “lead to a new standard to protect users and encourage Clear Signing across DApps,” and urged dapp developers to adopt clear signing.
