# Write Your First NFT

### Prerequisites

Before you begin, ensure you have the following:

* Git: Used for code management and obtain examples.
* Node.js: Install it from [nodejs.org](https://nodejs.org/).
* Pharos Devnet/Testnet Access: Access to a Pharos node (local or remote) for interacting with the blockchain.

### Setup 1: Install Foundry

* [Foundry](https://book.getfoundry.sh/getting-started/installation)

### Setup 2: Set Up the Project

Clone the example repo:

```shell
git clone https://github.com/PharosNetwork/examples
cd examples/nft/foundry/contract
```

Install OpenZeppelin Contracts:

* Foundry uses forge to manage dependencies. Install OpenZeppelin contracts:

```shell
forge install OpenZeppelin/openzeppelin-contracts --no-git
```

### Setup 3: Write the NFT Contract

Create a New Solidity File:

* Create a new file for your NFT contract:

```shell
touch src/Token.sol
```

Write the Token Contract:

* Open `src/Token.sol` in your favorite text editor and add the following code:

```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import {ERC721} from "openzeppelin-contracts/contracts/token/ERC721/ERC721.sol";

contract Token is ERC721 {
    constructor() ERC721("Token", "MTK") {}
}
```

Compile the Smart Contract:

* Use forge to compile the contract:

```shell
forge build
```

Test the Smart Contract

* Use forge to test the contract:

```shell
forge test
```

### Step 4: Deploy the Token Contract

Set the private key:

```shell
export PRIVATE_KEY=<your private key>
```

Create a Deployment Script:

* Create a new file for the deployment script:

```shell
touch script/DeployToken.s.sol
```

Write the Deployment Script:

* Open script/DeployToken.s.sol and add the following code:

```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "forge-std/Script.sol";
import "../src/Token.sol";

contract DeployToken is Script {
    function run() external {
        uint256 deployerPrivateKey = vm.envUint("PRIVATE_KEY");
        vm.startBroadcast(deployerPrivateKey);

        Token token = new Token(1000000); // Initial supply of 1,000,000 tokens

        vm.stopBroadcast();
    }
}
```

Deploy the Contract:

* Use forge to deploy the contract to the Pharos Testnet:

```shell
forge script script/DeployToken.s.sol --rpc-url <PHAROS_RPC_URL> --broadcast
```

### Step 5: Verify the Token Contract

* For Atlantic Testnet

```shell
forge verify-contract \
<contract_address> \
--constructor-args <abi_encoded_args> \
src/Token.sol:Token \
--chain-id 688688 \
--verifier blockscout \
--verifier-url https://api.socialscan.io/pharos-atlantic-testnet/v1/explorer/command_api/contract
```

* For Testnet

```shell
forge verify-contract \
<contract_address> \
--constructor-args <abi_encoded_args> \
src/Token.sol:Token \
--chain-id 688688 \
--verifier blockscout \
--verifier-url https://api.socialscan.io/pharos-testnet/v1/explorer/command_api/contract
```

> Note: Replace with your token contract address

### Step 6: Interact with the NFT Contract

Open `script/InteractToken.s.sol` and add the following code:

```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.13;

import {Script, console} from "forge-std/Script.sol";
import {Token} from "../src/Token.sol";

contract InteractToken is Script {
    function run() external {
        uint256 deployerPrivateKey = vm.envUint("PRIVATE_KEY");
        vm.startBroadcast(deployerPrivateKey);

        Token token = Token(address(0x00)); // Replace with your token contract address

        // Check balance
        uint256 balance = token.balanceOf(msg.sender);
        console.log("Balance:", balance);

        // Transfer tokens
        token.transfer(address(0x00), 100); // Replace with recipient address and amount
        console.log("Tokens transferred");

        vm.stopBroadcast();
    }
}
```

Execute the script using forge:

```shell
forge script script/InteractToken.s.sol --rpc-url <PHAROS_RPC_URL> --broadcast
```

### Troubleshooting

* **Contract Deployment Fails**: Ensure you have enough testnet tokens to cover the deployment cost.
* **Interaction Issues**: Verify that the contract address and ABI are correct.
* **Insufficient Balance**: Ensure your wallet has enough tokens to transfer.

### Conclusion

Now that you’ve created and deployed your first NFT using Foundry.

This guide provides a comprehensive introduction to to creating and deploying an NFT on the Pharos blockchain. If you encounter any issues, refer to the Troubleshooting section or consult the Foundry documentation. Happy building! 🚀

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.pharos.xyz/developer-guide/foundry/write-your-first-nft.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
