# Using Remix ide

Here is a detailed explanation of what Remix IDE is and a step-by-step guide on how to deploy a TEP721 contract using Remix IDE:

## What is Remix IDE ?

***Remix IDE*** is an open-source, web-based integrated development environment (IDE) for writing, compiling, and deploying smart contracts. It is widely used for Ethereum and Ethereum-compatible blockchains such as TAN-chain. Remix IDE offers a user-friendly interface, powerful debugging features, and a variety of plugins to streamline the smart contract development process.

## Step-by-Step Guide to Deploy

Follow these steps to deploy a TEP721 contract using Remix IDE:

## 1.Open Remix IDE

Navigate to [***Remix IDE*** ](https://remix.ethereum.org/#lang=en\&optimize=false\&runs=200\&evmVersion=null)in your web browser. You will see the main interface, which consists of several panels, including the file explorer, the editor, and the terminal.<br>

## 2.Create a New File

In the file explorer on the left side of the screen:

* To create a new file, select the “File Explorer” icon from the menu, then click the “Create New File” icon.
* Type in the name of the file. It is our first program so let’s go with “TEP721NFT`.sol`” .

## 3.Write the Contract

Once the file is named we can begin writing Solidity code in the code editor. Paste or type the code below into Remix.<br>

## 4.Compile the Contract

* **Select the Compiler**: Click on the `Solidity Compiler` tab on the left sidebar.
* **Choose Compiler Version**: Select the appropriate compiler version (e.g., `0.8.20+commit.c7dfd78e`).
* **Compile the Code**: Click the `Compile` TEP721NFT`.sol` button.

## 5.Deploy the Contract

* **Select the Deployment Environment**: Click on the `Deploy & Run Transactions` tab.
* **Configure the Environment**:

  Select `Injected Web3` if you are using a Web3 wallet like MetaMask connected to the TAN-chain network.
* **Deploy the Contract**:
  * Ensure TEP721NFT is selected in the contract dropdown.
  * Click the `Deploy` button.
