Mint Datatokens
This tutorial guides you through the process of minting datatokens and sending them to a receiver address. The tutorial assumes that you already have the address of the datatoken contract which is owned by you.
Create a new file in the same working directory where configuration file (
config.js) and .env files are present, and copy the code as listed below.mint_datatoken.js
mint_datatoken.js
// Note: Make sure .env file and config.js are created and setup correctly
const { oceanConfig } = require('./config.js');
const { amountToUnits } = require ('@oceanprotocol/lib');
const ethers = require('ethers');
// Define a function createFRE()
const createMINT = async () => {
let config = await oceanConfig();
const publisher = config.publisherAccount
const publisherAccount = await config.publisherAccount.getAddress()
const minAbi = [
{
constant: false,
inputs: [
{ name: 'to', type: 'address' },
{ name: 'value', type: 'uint256' }
],
name: 'mint',
outputs: [{ name: '', type: 'bool' }],
payable: false,
stateMutability: 'nonpayable',
type: 'function'
}
]
const tokenContract = new ethers.Contract(config.oceanTokenAddress, minAbi, publisher)
const estGasPublisher = await tokenContract.estimateGas.mint(
publisherAccount,
amountToUnits(null, null, '1000', 18)
)
const trxReceipt = await sendTx(
estGasPublisher,
publisher,
1,
tokenContract.mint,
publisherAccount,
amountToUnits(null, null, '1000', 18)
)
return {
trxReceipt
};
};
// Call the createFRE() function
createMINT()
.then(({ trxReceipt }) => {
console.log(`TX Receipt ${trxReceipt}`);
process.exit(1);
})
.catch((err) => {
console.error(err);
process.exit(1);
});
Execute script
node mint_datatoken.js
