Enjin NFT Batch Creation Example

This project is an example of how to create multiple collections and NFTs on the Enjin Matrixchain blockchain. It demonstrates how to batch-mint tokens in a scalable and efficient manner.

Project Structure

  • main.ts: The entry point of the project. It connects to the Enjin Matrixchain, creates collections, and mints tokens in batches.
  • multiTokens.ts: Contains methods to interact with the multi-tokens pallet, including creating collections and minting tokens.
  • utils.ts: Provides utility functions for signing and sending transactions.

Environment Variables

To run the project, ensure the following environment variables are set:

  • BOT_KEY: The private key or mnemonic of the account that will create collections and mint tokens.
  • WS_ENDPOINT: WebSocket endpoint for connecting to the Enjin or Canary Matrixchain.
  • COLLECTION_COUNT: Number of collections to create.
  • TOKEN_COUNT_PER_COLLECTION: Number of tokens to mint in each collection.
  • TOKEN_COUNT_IN_BATCH: Number of tokens to mint in a single batch. Maximum is 250.

Running the Project

  1. Install dependencies:

    npm install

  2. Create .env file and set the environment variables.

    cp .env.example .env

  3. Start the project:

    npm start

The script will automatically create the specified number of collections and mint the tokens according to the environment variables.

Example

If you want to create 2 collections with 1000 tokens each, with 100 tokens minted in each batch, set the following in your .env file:

COLLECTION_COUNT=2
TOKEN_COUNT_PER_COLLECTION=1000
TOKEN_COUNT_IN_BATCH=100

Then run the script to mint the tokens in multiple collections.
