Generate TON Connect Proof

TON Connect proof is used for authentication with backend services. This generates a cryptographic proof that the user owns the wallet.

import { useDynamicContext } from '@dynamic-labs/sdk-react-core';
import { isTonWallet, TonConnectProof } from '@dynamic-labs/ton';

  const onGenerateProof = async () => {
    if (!primaryWallet || !isTonWallet(primaryWallet)) {

    }

    // Generate the TON Connect proof
    const payload = 'authentication-challenge-from-backend';
    const proof: TonConnectProof = await primaryWallet.generateTonConnectProof(
      payload,
    );

    console.log('TON Connect Proof:', proof);

    //   payload: "authentication-challenge-from-backend",
