# 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. #### Prerequisites * [Obtain an API key](configuration.md#obtaining-api-key-for-ethereum-node-provider) * [Set up the .env file](configuration.md#create-a-.env-file) * [Install the dependencies](configuration.md#setup-dependencies) * [Create a configuration file](configuration.md#create-a-configuration-file) #### Create a script to mint datatokens Create a new file in the same working directory where configuration file (`config.py`/`config.js`) and `.env` files are present, and copy the code as listed below. {% tabs %} {% tab title="ocean.js" %} {% code title="mint_datatoken.js" %} ```javascript // Import dependencies const { NftFactory, Datatoken } = require('@oceanprotocol/lib'); const Web3 = require('web3'); const { web3Provider, oceanConfig } = require('./config'); // Create a web3 instance const web3 = new Web3(web3Provider); // Change this const datatokenAddress = "0xD3542e5F56655fb818F9118CE219e1D10751BC82" const receiverAddress = "0xBE5449a6A97aD46c8558A3356267Ee5D2731ab5e" // Create a function which will take `datatokenAddress` and `receiverAddress` as parameters const mintDatatoken = async (datatokenAddress, receiverAddress) => { const accounts = await web3.eth.getAccounts(); const publisherAccount = accounts[0]; // Create datatoken instance const datatoken = new Datatoken(web3); // Get current datatoken balance of receiver let receiverBalance = await datatoken.balance( datatokenAddress, receiverAddress ); console.log(`Receiver balance before mint: ${receiverBalance}`); // Mint datatoken await datatoken.mint( datatokenAddress, publisherAccount, '1', receiverAddress ); // Get new datatoken balance of receiver receiverBalance = await datatoken.balance( datatokenAddress, receiverAddress ); console.log(`Receiver balance after mint: ${receiverBalance}`); }; // Call mintDatatoken(...) function defined above mintDatatoken(datatokenAddress, receiverAddress) .then(() => { process.exit((err) => { console.error(err); process.exit(1); }); }) .catch((err) => { console.error(err); process.exit(1); }); ``` {% endcode %} **Execute script** ``` node mint_datatoken.js ``` {% endtab %} {% tab title="ocean.py" %} {% code title="mint_datatoken.py" %} ```python # Note: Ensure that .env and config.py are correctly setup from config import web3_wallet, ocean # Change this datatoken_address = "0xD3542e5F56655fb818F9118CE219e1D10751BC82" receiver_address = "0xBE5449a6A97aD46c8558A3356267Ee5D2731ab5e" datatoken = ocean.get_datatoken(datatoken_address) print(f"Balance before mint: {datatoken.balanceOf(receiver_address)}") # Mint datatokens datatoken.mint( account_address=receiver_address, value=ocean.to_wei("1"), from_wallet=web3_wallet, ) print(f"Balance after mint: {datatoken.balanceOf(receiver_address)}") nt_d ``` {% endcode %} **Execute script** ``` python mint_datatoken.py ``` {% endtab %} {% endtabs %}
