# Verify Sui Signatures
> Verify signed messages and transactions using the Sui SDK with Para
export const Card = ({imgUrl, title, description, href, horizontal = false, newTab = false}) => {
const [isHovered, setIsHovered] = useState(false);
const handleClick = e => {
e.preventDefault();
if (newTab) {
window.open(href, '_blank', 'noopener,noreferrer');
} else {
window.location.href = href;
}
};

};
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.
```typescript theme={null}
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 ;
}
```
Use `verifyTransaction(transactionBytes, signature)` to verify a transaction signature, and a `MultiSigPublicKey`'s `verifyPersonalMessage` / `verifyTransaction` to verify a combined multisig signature.
