# Message Signature

Message signature is a cryptographic technology used to ensure data security. Its main purpose is to verify the origin and integrity of the information, prevent tampering during transmission, and prove the sender's identity. In scenarios such as cryptocurrency transactions, electronic contract signing, and secure communication, message signature is an essential security guarantee.

## **Message Signature Process:**

1. Select the wallet and access the message signature page. Please note that Cregis only supports message signing with single-signature wallets.<br>

4. Once the verification is completed, the message signature will be successfully processed. The signature hash will be displayed in a pop-up window after the signature is successfully completed. This record will not be stored in the system, so please remember to copy the signature information for future reference.\ <br>
