Create AINFT object and Mint

You can create AINFT compliant 721 standard on AIN Blockchain. In this tutorial, We create AINFT on testnet and mint it.

Requirement

• Node

• IDE (recommend VS Code)

Step1. Initialize project

First, Create project to create AINFT. Make your directory and move it.

mkdir my-ainft
cd my-ainft

and Initialize project.

npm init

Step2. Install ainft-js

Install ainft-js. We can create, mint and transfer AINFT with ainft-js.

npm install @ainft-team/ainft-js

Step3. Create Account

Create account to create AINFT. If you have ain account, you can use it.

const AinftJs = require('@ainft-team/ainft-js').default;

const account = AinftJs.createAccount();
console.log(account);

// {
//   address: '0x74703a44905daB6582d62A45705a1c3ff966523f',
//   private_key: ... ,
//   public_key: '9451c9c91f84ef5cc5f83fe86413c9eb283a6ba3924d0a351ac598c3895b9f6a57b10513a885a98aff8ccea2aa3101c07f799bcb25cbcb1184f67f6c2cb72541'
// }

If you have AIN Wallet, you can use account in Wallet.

Like below picture, you can export private key of account you want in wallet account setting.

Step4. Get testnet ain from faucet

In order to create NFT, we need some ain. In Faucet, you can get some ain for tutorial. Enter your ain account address and get some ain.

https://faucet.ainetwork.ai/

After then, you can check your balance in Wallet.

You can also check insight by entering the address in the search box at the top right.

Step5. Create Ainft object

Then, we’ll intialize ainft-js and create AINFT object. Use create function with NFT’s name and symbol you want. You can look appId, nftId and txHash as resulting in standard out. and You can check if transaction is completed by enter txHash in insight. Please check it and proceed to the next step.

const config = {
  ainftServerEndpoint: 'https://ainft-api-dev.ainetwork.ai',
  ainBlockchainEndpoint: 'https://testnet-api.ainetwork.ai',
}
const ainftJs = new AinftJs('YOUR_PRIVATE_KEY', config);

const name = 'ainft_for_tutorial';
const symbol = 'TUTORIAL';

ainftJs.nft.create(name, symbol)
.then((res) => {
	const { txHash, ainftObject } = res;
	console.log(txHash);
	console.log(ainftObject.id);
	console.log(ainftObject.appId);
})
.catch((error) => {
	console.log(error);
});

// 0xe3c4c0e4982a7ebc1224d9e8ff84a86d17ff4facd5ac25e6bec2c9bfb32da8c2
// 0x799a71A8DDdECC23F1B15d222BcB01ae674751B8
// ainft721_0x799a71a8dddecc23f1b15d222bcb01ae674751b8

You can check the transaction results by entering the transaction hash in the search box at the top right.

Step6. Mint

Finally, Let’s mint AINFT. You can mint AINFT with tokenId you want to mint and the ain account address you want to receive AINFT.

You can see if transaction is complete by retrieving tx hash in insight.

const to = '0x74703a44905daB6582d62A45705a1c3ff966523f'; // Replace to your receiver address.
const tokenId = '1'; // Replace to token Id you want.
const ainftObjectId = '0x799a71A8DDdECC23F1B15d222BcB01ae674751B8'; // Replace to your ainft object id.

const main = async () => {
  try {
    const ainftObject = await ainftJs.nft.get(ainftObjectId);
    const result = await ainftObject.mint(to, tokenId);
    console.log(result);
  } catch(error) {
    console.log(error);
  }
}

main();

// {
//   tx_hash: '0xbdca2430d425e78114a921eda073400cdf8ad9d4c05e8fda59931b39a69455f8',
//     result: {
//     gas_amount_total: { bandwidth: [Object], state: [Object] },
//     gas_cost_total: 0,
//       result_list: { '0': [Object], '1': [Object], '2': [Object], '3': [Object] },
//     gas_amount_charged: 0
//   }
// }
