Sign message

This operation creates a transaction to sign the provided message using cryptographic techniques.

In some scenarios, you want to sign a message for identity authentication or transaction approval. You need to provide details such as the source address, destination address, and the message to be signed. A transaction request for tracking is returned upon successful operation.

You can get the signature result by calling Get transaction information.

This operation only applies to transactions from MPC Wallets.
