Verify Sui Signatures

Verify a Sui signature against the signer’s public key to confirm a message or transaction was signed by the expected wallet.

Verify a Personal Message

The signer’s public key (a @mysten/sui Ed25519PublicKey) exposes verifyPersonalMessage and verifyTransaction, which validate the serialized signature against the original bytes.

import { useParaSuiSigner } from "@getpara/react-sdk";

function VerifyMessage() {
  const { suiSigner } = useParaSuiSigner();

  const run = async () => {
    if (!suiSigner) return;

    const message = new TextEncoder().encode("Hello, Sui!");
    const { signature } = await suiSigner.signPersonalMessage(message);

    const isValid = await suiSigner.getPublicKey().verifyPersonalMessage(message, signature);
    console.log("Signature valid:", isValid);
  };

  return <button onClick={run}>Verify</button>;
}

Use verifyTransaction(transactionBytes, signature) to verify a transaction signature, and a MultiSigPublicKey’s verifyPersonalMessage / verifyTransaction to verify a combined multisig signature.
