Create NFT Batch

Create a batch of NFTs on the Aventus network.

Creating a batch of NFTs doesn't mint all the total number of NFTs indicated for this batch via the totalSupply variable. It simply instructs the blockchain that you will be minting multiple NFTs that should be linked together as part of a batch, and the blockchain should not allow minting a higher number of NFTs than specified at creation.

This page is kept simple to show the function signature and how it can be used. To understand the various variable names and their constraints, HERE is an explainer. For a further deep-dive into how the Aventus Network supports NFTs, check this out.

await api.send.createNftBatch(totalSupply, royalties, T1_ADMIN_NAME);

important

This operation uses a relayer account that the sender authorizes to submit the transfer transaction. You can learn more about relayers HERE.

important

You can get the AVN_GATEWAY_URL and Relayer here.

Example

const { AvnApi, SetupMode, SigningMode } = require("avn-api");
const AVN_GATEWAY_URL = "https://gateway.testnet.aventus.network/";

const singleUserOptions = {
	suri: "0x5392ca60a61aea99fce14358798de93c1bc11c3696a905718738c71fae539c24", // this is from the generated example account
	setupMode: SetupMode.SingleUser,
	signingMode: SigningMode.SuriBased,
};

const avnSdk = new AvnApi(AVN_GATEWAY_URL, singleUserOptions);

// number of nfts available to mint in this batch
const TOTAL_SUPPLY = 5;

// follow the link above to learn about T1_ADMIN_NAME
const T1_ADMIN_NAME = "0x1a2...b3c";

//see next page for more info on Royalties.
const ROYALTIES = [];

async function main() {
	await avnSdk.init();
	const api = await avnSdk.apis();

	let request_id = await api.send.createNftBatch(
		TOTAL_SUPPLY,
		ROYALTIES,
		T1_ADMIN_NAME
	);
	// Returns a request id
	console.log(request_id);
}

(async () => {
	await main();
})();

You have now successfully submitted a transaction to the AVN to create a batch of NFTs.
