# 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.

|
// Call mintDatatoken(...) function defined above
|
|
mintDatatoken(datatokenAddress, receiverAddress)
