1. Install Node.js
2. Create a directory,such as TRC20Mint
3. Open TRC20Mint, execute command:npm init
4. Execute command:npm install tronweb
5. Create an index.js file,copy the code below
6. Run index.js:node index.js

const TronWeb = require('tronweb');
const HttpProvider = TronWeb.providers.HttpProvider;
const fullNode = new HttpProvider("https://api.trongrid.io");
const solidityNode = new HttpProvider("https://api.trongrid.io");
const eventServer = new HttpProvider("https://api.trongrid.io");
const privateKey = "your privateKey"; //
const tronWeb = new TronWeb(fullNode, solidityNode, eventServer, privateKey);

const blackHole = "T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb";  //black hole address

const memo = 'data:,{"p":"trc-20","op":"mint","tick":"trxi","amt":"1000"}';  

async function main() {

    const unSignedTxn = await tronWeb.transactionBuilder.sendTrx(blackHole, 1); //0.000001 TRX is the minimum transfer amount.
    const unSignedTxnWithNote = await tronWeb.transactionBuilder.addUpdateData(unSignedTxn, memo, 'utf8');
    const signedTxn = await tronWeb.trx.sign(unSignedTxnWithNote);
    console.log("signed =>", signedTxn);
    const ret = await tronWeb.trx.sendRawTransaction(signedTxn);
    console.log("broadcast =>", ret);
}

main().then(() => {

    })
    .catch((err) => {
        console.log("error:", err);
    });

• Receiver address:T9yD14Nj9j7xAB4dbGeiX9h8unkKHxuWwb.
• Transfer amount 0.000001 TRX
• Click on Advanced Settings and fill in data:,{"p":"trc-20","op":"mint","tick":"trxi","amt":"1000"}

1. Recording the block number of deploy inscription.
2. Get all transactions of black hole address.
3. Use the FULL NODE HTTP API to get the from,to,data field of each txid, match all mint inscriptions. For more details, please refer to the following link: https://developers.tron.network/reference/wallet-gettransactionbyid.
4. The obtained addresses need to undergo encoding conversion to Tron wallet addresses. For more details, please refer to the following link: https://www.btcschools.net/tron/tron_tool_base58check_hex.php.

Because TRON blockchain cannot transfer to yourself address.We decided transfer to the black hole address of the TRON blockchain. Refer to the black hole address given in the official documentation of the TRON blockchain.

Because TRON blockchain cannot transfer zero amount, 0.000001 TRX is the minimum transfer amount.
