The Blind Signing feature is no longer available in the latest version of the Ethereum app (Version 1.11.1 or above). As a result, you cannot enable blind signing for transactions. If you encounter a transaction that requires blind signing, you will receive this error: "This transaction cannot be trusted". Learn more about this error below.
Blind Signing was formerly called Contract Data. Please note that Contract Data and Blind Signing are the same feature, only the name has changed.

This error means that it’s not possible to clear sign the transaction. Your Ledger device is not able to properly decode the transaction. If you decide to proceed, you need to accept the associated risk—you could be authorizing a malicious action that can drain your wallet.
Clear signing your transactions
Don’t trust, verify is Ledger’s philosophy when signing both your on-chain and off-chain transactions with your Ledger device. Clear signing, as opposed to blind signing, allows you to see what you sign in a human-readable format instead of raw and complex data. This way, you can avoid signing rogue transactions unintentionally.
Thanks to the secure screen of your Ledger device and Ledger’s cryptographic infrastructure, you are guaranteed that what you see is what you sign.

Finally, when diving into the world of DeFi, it is essential to remember that you ultimately trust the smart contracts you interact with, to behave as expected. Always be careful which contracts you use and whether they have been reviewed or audited.
