In this tutorial we will create a non-fungible token (NFT) and deploy to a public testnet.

ERC721 is a standard for representing ownership of [_non-fungible_ tokens](https://docs.openzeppelin.com/contracts/3.x/tokens#different-kinds-of-tokens), that is, where each token is unique such as in real estate or collectibles.

We will use [Presets](https://docs.openzeppelin.com/contracts/3.x/api/presets) contracts in [OpenZeppelin Contracts 3](https://docs.openzeppelin.com/contracts/3.x/) to create an ERC721 and deploy using Truffle.

## Setting up the Environment

We begin by creating a new project.

```auto
$ mkdir mynft && cd mynft
$ npm init -y

```

Then we install [OpenZeppelin Contracts](https://docs.openzeppelin.com/contracts) which has an implementation of ERC721.

```auto
npm install --save-dev @openzeppelin/contracts

```

Next we install a development tool for deployment, for this tutorial we will use [Truffle](https://www.trufflesuite.com/) but we could use any other tools such as Buidler, Remix or [OpenZeppelin CLI](https://docs.openzeppelin.com/cli).

```auto
npm install truffle

```

## Getting the contract artifacts

We will setup our Solidity project using `truffle init` to create a `contracts` directory and configuration to connect to a network.

```auto
$ npx truffle init
This directory is non-empty...
? Proceed anyway? (Y/n)
Starting unbox...
=================

? Proceed anyway? Yes
✔ Preparing to download box
✔ Downloading
✔ cleaning up temporary files
✔ Setting up box

Unbox successful, sweet!

Commands:

  Compile: truffle compile
  Migrate: truffle migrate
  Test contracts: truffle test

```

We are going to use Preset [`ERC721PresetMinterPauserAutoId`](https://docs.openzeppelin.com/contracts/3.x/api/presets#ERC721PresetMinterPauserAutoId) which is an ERC721 that is preset so it can be minted (with auto token ID and metadata URI), paused and burned.

The Preset contracts have already been compiled, so we only need to copy the artifacts to the `build/contracts` directory.

```auto
$ mkdir -p build/contracts/
$ cp node_modules/@openzeppelin/contracts/build/contracts/* build/contracts/

```

Using your favorite editor create `2_deploy.js` in the `migrations` directory with the following contents:

```auto
// migrations/2_deploy.js
// SPDX-License-Identifier: MIT
const ERC721PresetMinterPauserAutoId = artifacts.require("ERC721PresetMinterPauserAutoId");

module.exports = function(deployer) {
  deployer.deploy(ERC721PresetMinterPauserAutoId, "My NFT","NFT", "https://my-json-server.typicode.com/abcoathup/samplenft/tokens/");
};

```

## Deploy the contract to a local blockchain

We will use [`truffle develop`](https://www.trufflesuite.com/docs/truffle/reference/truffle-commands#develop) to open a Truffle console with a development blockchain

```auto
$ npx truffle develop
Truffle Develop started at http://127.0.0.1:9545/

```

We can deploy our new NFT to our development blockchain using migrate.

```auto
truffle(develop)> migrate

```

We can then use our deployed contract.

```auto
truffle(develop)> nft = await ERC721PresetMinterPauserAutoId.deployed()
undefined

```

## Interact with our Token

The accounts that we can use were displayed when we started `truffle develop`

### Token metadata

We can call the contract to read token metadata such as `name`, `symbol` and `baseURI`

```auto
truffle(develop)> await nft.name()
'My NFT'
truffle(develop)> await nft.symbol()
'NFT'
truffle(develop)> await nft.baseURI()
'https://my-json-server.typicode.com/abcoathup/samplenft/tokens/'

```

### Mint

We can send a transaction to mint tokens to a given account, from an account with the minter role.  
In our case we are minting from the account which deployed the token, which is given the minter role.

We will mint 1 NFT with token ID 0.

```auto
truffle(develop)> await nft.mint("0x0445c33bdce670d57189158b88c0034b579f37ce")
{ tx:
   '0xd301a60dbb8ac187687f6639f200d4e6f2cfa065923092b3940330e35a26421d',
  receipt:
   { transactionHash:
      '0xd301a60dbb8ac187687f6639f200d4e6f2cfa065923092b3940330e35a26421d',
     transactionIndex: 0,
     blockHash:
      '0x3ad3cfcb26da0c969e9d5a5414a5e90a91a3a862c9e9082afc38a0ec0f1a5d00',
     blockNumber: 5,
     from: '0x0445c33bdce670d57189158b88c0034b579f37ce',
     to: '0xdee9411430c7dd9b67fc6da723de729adab50ad7',
     gasUsed: 156470,
...

```

We can check the owner of the token and the token URI for the metadata

```auto
truffle(develop)> await nft.ownerOf(0)
'0x0445c33BdCe670D57189158b88c0034B579f37cE'
truffle(develop)> await nft.tokenURI(0)
'https://my-json-server.typicode.com/abcoathup/samplenft/tokens/0'

```

## MetaData

[EIP-721](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-721.md) includes an optional **metadata extension** with a `name`, `symbol` and for each tokenID a `tokenURI` with can point to a JSON file with `name`, `description` and `image` for the given token ID.

How you create and host this metadata is up to you.  
I would suggest using a domain that you control to point to where you host the data so that you can move it as required.

For this tutorial, we will use [My JSON Server](https://my-json-server.typicode.com/) where we can store a single JSON file in a GitHub repository that we can access via a fake JSON server.

⚠ For production we need to store our metadata in a permanent location that can exist for the life of the token.

For images we will use twemoji Graphics from [https://github.com/twitter/twemoji](https://github.com/twitter/twemoji) which are licensed under [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/)

A sample JSON for tokenID 0 is:  
[http://my-json-server.typicode.com/abcoathup/samplenft/tokens/0](http://my-json-server.typicode.com/abcoathup/samplenft/tokens/0)

## Deploy to a public testnet

Next we will deploy to Rinkeby public testnet as OpenSea supports Rinkeby for testing.

To deploy, we will use the instructions for [Connecting to Public Test Networks with Truffle](https://forum.openzeppelin.com/t/connecting-to-public-test-networks-with-truffle/2960)

You will need the following:

- An Infura project ID (or a public node provider of your choice)
- `@truffle/hdwallet-provider` installed
- Configure `truffle-config.js` for Rinkeby network
- A funded testnet account and mnemonic
- A `secrets.json` or another secret-management solution. **Make sure you don’t commit this to GitHub!**

My `truffle-config.js` has the following `rinkeby` configuration:

```auto
    rinkeby: {
      provider: () => new HDWalletProvider(mnemonic, `https://rinkeby.infura.io/v3/${projectId}`),
      network_id: 4, // Rinkeby's id
      gas: 8500000,        
      gasPrice: 1000000000, // 1 gwei (in wei) (default: 100 gwei)
      confirmations: 2, // # of confs to wait between deployments. (default: 0)
      timeoutBlocks: 200, // # of blocks before a deployment times out (minimum/default: 50)
      skipDryRun: true // Skip dry run before migrations? (default: false for public nets )
    },

```

### Deploy to Rinkeby

```auto
$ npx truffle console --network rinkeby
truffle(rinkeby)> migrate

### Mint

We can send a transaction to mint tokens to a given account, from an account with the minter role.

```auto
truffle(rinkeby)> nft = await ERC721PresetMinterPauserAutoId.deployed()
undefined

```

In our case we are minting from the account which deployed the token, which is given the minter role.

To see configured accounts run the command `accounts`.

```auto
truffle(rinkeby)> accounts
[ '0x77737a65C296012C67F8c7f656d1Df81827c9541',

```

We will mint 1 NFT with token ID 0. Specify the address that you want to be the token holder (`0x77737a65C296012C67F8c7f656d1Df81827c9541` is one of my test accounts)

```auto
truffle(rinkeby)> await nft.mint("0x77737a65C296012C67F8c7f656d1Df81827c9541")
{ tx:
   '0xce8132ff0ffce128b8508d396fb0625a12c839fd1ee886eab5b4ddaf2755ca6f',
  receipt:
   { blockHash:
      '0x3f546e5caa9142d89dc3a87e7d369ba175629b480840d8bf88bd146f205e62de',
     blockNumber: 6572543,
     contractAddress: null,
     cumulativeGasUsed: 1410693,
     from: '0x77737a65c296012c67f8c7f656d1df81827c9541',
     gasUsed: 149870,
...

```

## OpenSea

We can validate our metadata

📓 To obtain the address of our contract on Rinkeby we can use the Truffle console

```auto
truffle(rinkeby)> nft.address
'0x5c5c53D13aD8725cFE551D6E9dB93e9a9D38D78D'

```

OpenSea metadata validation is at `https://rinkeby-api.opensea.io/asset/[nft contract address]/[token id]/validate`

My example can be found at:  
[https://rinkeby-api.opensea.io/asset/0x5c5c53D13aD8725cFE551D6E9dB93e9a9D38D78D/0/validate/](https://rinkeby-api.opensea.io/asset/0x5c5c53D13aD8725cFE551D6E9dB93e9a9D38D78D/0/validate/)

Assuming that there aren’t any issues with our metadata, we can view our NFT on OpenSea at `https://rinkeby.opensea.io/assets/[nft contract address]/[token id]`

My example can be found at:

> **[My NFT 0 - My NFT | OpenSea](https://testnets.opensea.io/assets/0x5c5c53D13aD8725cFE551D6E9dB93e9a9D38D78D/0)**
>
> My NFT

## Next steps

- Create your artwork and metadata.
- Host your images and metadata.
- Define what rights your token holders have.

Can you elaborate on how to use the extension for metadata? I am looking to change the metadata for every token. I have deployed the ```  
ERC721PresetMinterPauserAutoId

```contract
Thank You

**FOR THOSE USING WINDOWS LISTEN UP:**

instead of using the linux/mac commands for copying the artifacts instead manually go into the @openzeppelin folder within the project and copy paste from @openzeppelin/contracts/build/contracts/ then go back to the main folder of desktop/mynft and paste all the 4 artifacts into the build/contracts folder.

Hi @jing,

Thanks for sharing. Whilst I use Windows 10, I do all my smart contract development on Windows Subsystem for Linux (WSL2).

For Windows users I recommend using WSL2. Much of the ecosystem is written for and tested on Linux, so life is much easier using WSL. [Solidity Smart Contract development on Windows](https://forum.openzeppelin.com/t/solidity-smart-contract-development-on-windows/2110)

I completed this and it was a really good tutorial!

There is one question that I dont know how to figure it out. Can somebody drop any reference for me about how to make my own image on twemoji. I tried to search for some, but just didnt find anything thats helpful. I want to upload my own img to twemoji, to get my own twemoji link (ex: [https://twemoji.maxcdn.com/svg/1f40e.svg](https://twemoji.maxcdn.com/svg/1f40e.svg)). Can I upload my own img or I have to “draw my own” from twemoji?

Thanks for your support!

You can’t upload images to twemoji, you will need to host your own images somewhere else, such as GitHub Pages, or IPFS via [Pinata](https://pinata.cloud).

my nft is deployed at 0x0843e3bdEc2c8F640FCead18BBD7929593B58cA6 and token 0 was minted, I’ve followed the tutorial and it also validated successfully, but my image doesn’t show up, why could that be? thanks in advance

When you say “my image doesn’t show up”, where are you trying to see it? I can see the contract on Rinkeby and it seems to have correct metadata.
