Never Blind Sign on Dapps that are not 100% trusted

In view of the inherent risks, it is recommended that you use multiple accounts to interact with Dapp. And use an account with only a small portion of your assets to perform Blind Sign, and never put all your assets at risk.

【Blind Sign】 refers to the hardware performing Blind Sign on the transaction, but does not currently support the analysis of transaction metadata. Please make sure that you are aware of the potential risks of this feature before enabling it.

Blind Sign is not safe, which is why we implemented credible display in the first place. The purpose of trusted display is to explain the transaction and 100% guarantee the content of your signature.

However, trusted display needs to analyze transaction metadata, but due to various restrictions and compatibility issues, it is impossible to hash all transactions.

Therefore, you can turn on 【Blind Sign】. This function allows you to sign the content that the hardware wallet cannot parse, but therefore you cannot verify the content you are signing.

In view of the inherent risks, it is recommended that you use multiple accounts to interact with Dapp. And use an account with only a small portion of your assets to perform Blind Sign, and never put all your assets at risk.
