generateMintSignature

Generates a payload and signature for minting ERC721 tokens via a MintableERC721 module.

Example

import { MintableERC20 } from "thirdweb/modules";
 
// generate the payload and signature, this is typically done on the server
// requires to be generated with a wallet that has the MINTER_ROLE
const { payload, signature } =
  await MintableERC721.generateMintSignature({
    account,
    contract,
    nfts: [
      {
        name: "My NFT",
        description: "My NFT",
        image: "https://example.com/image.png",
      },
    ],
    mintRequest: {
      recipient: "0x...",
    },
  });
 
// prepare the transaction, this is typically done on the client
// can be executed by any wallet
const transaction = MintableERC20.mintWithSignature({
  contract,
  payload,
  signature,
});
 
// Send the transaction
await sendTransaction({ transaction, account });
function generateMintSignature(
): Promise<{
  payload: {
    amount: bigint;
    baseURI: string;
    data: `0x${string}`;
    to: `0x${string}`;
  };
  signature: `0x${string}`;
}>;
