The End to End Guide For Minting a Single NFT on the AVN

This guide will walk you through successfully submitting a transaction on the AVN to mint an NFT and verify the state of the transaction.

The first thing we need to do is ensure that you have npm installed. You'll find instructions on how to do this here. You'll also find instructions on how to install the avn-api library.

Note, all transactions on the AVN must be paid for using AVT, so going forward it's important for you to have some AVT in your account. There are multiple ways to purchase AVT and this page provides instructions on how to get some. Note, you'll need 1 AVT in your SURI account to use the API. The tokens need to be lifted (moved) to the Aventus Network, and there are also instructions for that too here.

Once you have some AVT in your account, of which you can check your account balance here, let's get to the exciting bit, minting an NFT by submitting a transaction to the AVN. For this guide, we'll show a simple transaction minting a single NFT.


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

You can get the AVN_GATEWAY_URL and AVN_RELAYER here.

const { AvnApi, SetupMode, SigningMode } = require("avn-api");
const AVN_GATEWAY_URL = "gateway url of your chosen network";
const options = {
suri: "suri of your account",
setupMode: SetupMode.SingleUser,
signingMode: SigningMode.SuriBased,
hasPayer: true,

const EXTERNAL_REF = "https://5DA/gxV"; //this takes an arbitrary value
const T1_ADMIN_NAME = "0x1a2...b3c"; //smart contract on Ethereum

const ROYALTIES = [
recipient_t1_address: "0x1a2...c3b", //Ethereum address of a royalty recipient
rate: {
parts_per_million: 10000, // 1%

async function main() {
const avnSdk = new AvnApi(AVN_GATEWAY_URL, options);
await avnSdk.init();
const api = await avnSdk.apis();

const result = await API.send.mintSingleNft(
// Returns a request id

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

Expected Transaction Submission Output


Congratulations! You've now successfully minted an NFT on the AVN.

State of the Transaction

To query the AVN on the state of the transaction:

let status = await api.poll.requestState(requestId);

Expected State Output

"txHash": "0x37b5aa6...ae1c773c0acbc63dc90",
"status": "Processed",
"blockNumber": "125412",
"transactionIndex": "2"
