Ends a listing on Ethereum for NFTs in a batch

Ends a listing for all ETH-Bought NFTs in a batch on a marketplace.

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. This is a cross-chain transaction given that it requires communication between the Aventus parachain and the Ethereum blockchain during the lifecycle of the transaction

await api.send.endEthereumBatchSale(ethereumTransactionHash);

important

You can get the AVN_GATEWAY_URL for all networks 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);

// replace with the ethereum transaction hash of the NFT sale you're trying to end.
const ethereumTransactionHash = "0xcd591...72f6";

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

	let request_id = await api.send.endEthereumBatchSale(ethereumTransactionHash);
	// Returns a request id
	console.log(request_id);
}

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

You have now successfully submitted a transaction to the AVN to end a listing for all NFTs in a batch.

You can query the state of your transaction here using the returned request id.

Production Example

Multiple NFTs have been minted on the AVN and HERE is a link to the AVN Explorer that provides more detail on the minted NFT. Click on the Advanced tab on the page to view more details on the transaction.
