MintTransfer method

The mintTransfer() is a payable method that allows users to buy newly minted TPAs. To use this method, you need to send plaquePrice * _names.length amount of value in Wei to this transaction as TPAs price.

function mintTransfer(bytes32[] _names, uint32[] _amounts, string _outputData) external payable

Input & Output

• _names: an array of bytes32 representing the TPA names to be minted.

• _amounts: an array of uint32 representing the amount of TPAs to be minted. The length of this array should be the same as the length of the _names array, and all elements should be set to 1.

• _outputData: a string representing the output data to be sent to us. It should be a JSON-encoded object with either a "username" or a "name" property. Recording the username or TPA name in the output data and pinging someone is optional. However, it's worth noting that to ping a TPA, the TPA owner must have registered their username on the platform. Additionally, you cannot use both the "username" and "name" properties simultaneously.

• This function doesn't return anything, only a transaction hash to follow your transaction with.

Usage

To use this method, you can create a new instance of the StageMeta smart-contract and call the mintTransfer() method, like this:

const options = {
  value: ethers.utils.parseEther("0.06498719370006499"), // TPAs price
  gasLimit: 500000,
};

const mintTransferResult = await stageMetaContract.mintTransfer(
  [
    ethers.utils.formatBytes32String("aaa-888"),
    ethers.utils.formatBytes32String("aaa-999")
  ],
  [1, 1],
  JSON.stringify({
    name: 'aaa-000', //or username: 'stagemeta'
  }),
  options
);
console.log("mintTransferResult:", mintTransferResult);
