Sign the message

note that the message is a string, not the txBytes of the transaction. Do not sign the transaction with this method!

import {StarknetWallet} from "@okxweb3/coin-starknet";

let wallet = new StarknetWallet()
const privateKey = "0x0603c85d20500520d4c653352ff6c524f358afeab7e41a511c73733e49c3075e";

        message: "0xec04138ec537328244f24236a84bb72d0fe428f6d4955ca20a5f6420066b5"
    }
}
const sig = await wallet.signMessage(param);

// verify
const verifyParam: VerifyMessageParams = {
    signature: "",
    data: {
        signature: sig.signature,
        hash: sig.hash,
        publicKey: sig.publicKey,
    }
