List a Batch of NFTs Open For Sale

Listing a batch of NFTs for sale requires firstly that the batch of NFTs exist, also that the initiator of the transaction is the creator of the batch, and finally, there are some NFTs within the batch that are not under the ownership of another account.

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.li stFiatNftBatchForSale(BATCH_ID);

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 AVN_API = require("avn-api");
const AVN_GATEWAY_URL = "<node_url>";
const options = {
	suri: "<account_suri>",
};
const API = new AVN_API(AVN_GATEWAY_URL, options);

// the string representing the batch Id
const BATCH_ID = "0xcd5...2f6";

async function main() {
	await api.init();

	let result = await api.send.listFiatNftBatchForSale(BATCH_ID);
	// Returns a request id
	console.log(result);
}

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