Minting Tokens

Start minting your token's supply. You can mint it straight into your players' wallets.

Suggest Edits

Now that you've got your tokens created, it's time to start minting them into player wallets as they are earned.

We call this "Play-to-Mint," giving players the power to create tokens themselves, which feels more rewarding.

Plus, it keeps your processes more efficient by delivering tokens right to players' wallets without any unnecessary transfer transactions.

What you'll need

There are two ways to use the Create Asset functionalities:

Option A. Using the Enjin Dashboard

In the Platform menu, navigate to "Tokens".
Locate the token you wish to mint, click the 3 vertical dots (⋮) to it's right, then click the "Mint" button.

Set the recipient, amount and Unit Price in the corresponding fields, and Click on "Mint"

The Transaction Request will then appear in the "Transactions" menu.

A notification appears after you create a <<glossary:Mutation>>.

A notification appears after you create a Mutation.

Clicking "**View**" on the notification will take you to your Transactions List.

Clicking "View" on the notification will take you to your Transactions List.

Since this transaction is a Mutation, you will need to sign the transaction using your Wallet.

  • If a Wallet Daemon is running and configured, the transaction request will be signed automatically.
  • If a wallet is connected such as the Enjin Wallet or Polkadot.js, the transaction must be signed manually by clicking the "Sign" button and approving the signature request in your wallet.

Option B. Using the Enjin API & SDKs

The BatchMint mutation enables you to efficiently create multiple tokens within a single blockchain transaction. This process, known as batch minting, simplifies the minting of multiple tokens, reducing transaction fees and processing time.

A WebSocket event will also be fired so you can pick up the transfer transaction in real time by listening to the app channel on the WebSocket.

More Fields and Arguments Available!

While the examples here cover the core functionalities of the BatchMint mutation, there are a few more settings you can adjust.

To view and understand all the available settings for the BatchMint mutation, refer to our GraphQL Schema on Apollo.

This resource will guide you in tailoring the BatchMint mutation to your specific requirements.

For instance, instead of batch minting with the MintParams object, you can batch create new tokens with the CreateParams object.
