type​

type: "txAuthDataSignatureResponse"

Parameters​

• params: {args: string;blockExpiration: number;chainID: TezosChainId;contractAddress: TezosContractAddress;functionName: TezosEntrypointName;nonce: number;userAddress: TezosImplicitAddress; } & {namespace: "tezos";userAddress: TezosImplicitAddress; }

Param​

The parameters required to get the transaction authorization data signature

Example​

Eip155:

import { createSdk } from "@compilot/js-sdk";

const compilotSdk = createSdk({ apiKey });

const txAuthDataSignature = await compilotSdk.getTxAuthDataSignature({
 namespace: "eip155",
 contractAbi: ExampleGatedNFTMinterABI,
 contractAddress: "0x123",
 functionName: "mintNFTGated",
 args: [account.address],
 userAddress: account.address,
 chainId: EvmChainId.parse(chainId),
});

if (!signatureResponse.isAuthorized) {
  throw new Error("User is not authorized");
}

// Mint Gated Nft with signature
const unsignedTx = encodeFunctionData({
  abi: contractAbi,
  functionName: "mintNFTGated",
  args: [account.address],
});

// Build the raw transaction data with the signature
const txData = (unsignedTx + signatureResponse.payload) as `0x${string}`;

// try to mint nft
const tx = await walletClient.data.sendTransaction({
  to: contractAddress,
  data: txData,
});
