Blind signing occurs when a hardware wallet displays unreadable cryptographic hashes instead of human-readable transaction details. Learn how attackers exploit this gap and how new standards like EIP-712 and clear-signing defend your assets.

Key points

Blind signing occurs when a hardware wallet signs an unreadable hexadecimal hash instead of human-readable transaction parameters.

Attackers exploit blind signing by altering smart contract payloads on compromised websites while showing safe screens to the user.

EIP-712 introduced typed structured data signing, allowing wallets to display readable fields like dApp identity, spender address, and amounts.

Hardware wallets do not inherently block malicious transactions if the user manually verifies and approves an unparsed data payload.

Clear-signing initiatives and standards like ERC-7730…
