Mint an NFT

Pre-requirements​

Before you can mint an NFT, you will need to:

Mint an NFT​

This example will connect to a node you defined as the API_ENDPOINT constant. Afterwards, the example will request a Bech32 address, if you don't have one the example will take care of generating it.

Create a Hot Wallet​

The example will later create a hot wallet and request funds from the faucet defined as the FAUCET constant.

Create the Output​

Once the generated wallet has outputs to mint the NFT, it will define an INftOutput object. The amount property is set to 0, as you need to calculate the required storage deposit using the TransactionHelper.getStorageDeposit(output, rentStructure) function, which takes any of the allowed OutputTypes.

Create the Transaction Essence​

Once you have created the output, you should create the ITransactionEssence, which will include the output. The example will then use the ITransactionEssence to generate the essenceHash using the TransactionHelper.getTransactionEssenceHash(essence) function.

Create the Transaction Payload​

With the created the transaction essence, you are now able to create the ISignatureUnlock which will be used to create the ITransactionPayload.

Submit the Block​

Once you have created the transaction payload, you can create the IBlock and submit it using the SingleNodeClient.blockSubmit(blockPartial) function.
