# Deploy using Foundry

[Foundry](https://getfoundry.sh/) is a Solidity framework for deploying smart contracts, built by [Paradigm](https://paradigm.xyz/) and written in Rust to be blazingly fast.

## Before you Begin

* Check if you are using the right [network configuration](https://docs.plume.org/plume/developers/network-information)
* Have enough test tokens in your wallet

{% hint style="info" %}

{% endhint %}

## Foundry Setup

Simply follow their ["Getting Started" documentation](https://book.getfoundry.sh/getting-started/installation) to install and run Foundry, then follow their ["Projects" documentation](https://book.getfoundry.sh/projects/creating-a-new-project) to create a new project. 

Run the following commands in your terminal:

```sh
curl -L https://foundry.paradigm.xyz | bash
foundryup
```

## Setup your project

To start a new project with Foundry, use [`forge init`](https://book.getfoundry.sh/reference/forge/forge-init.html):

```sh
forge init plume
```

Let's install the OpenZeppelin dependency required for our sample smart contract.

```sh
forge install openzeppelin/openzeppelin-contracts
```

<summary>Sample Smart Contract Code</summary>

This is a sample NFT contract based on [OpenZeppelin's open-source ERC-721](https://docs.openzeppelin.com/contracts/4.x/erc721) implementation to tokenize our CBO's prized Rolex watch on Plume.

{% code title="src/RolexYachtMaster40.sol" %}

```solidity
// SPDX-License-Identifier: MIT
pragma solidity ^0.8.25;

import {Ownable} from "@openzeppelin/contracts/access/Ownable.sol";
import {ERC721} from "@openzeppelin/contracts/token/ERC721/ERC721.sol";

contract RolexYachtMaster40 is Ownable, ERC721 {
    error NFTAlreadyMinted();
    bool private _minted;

    constructor() Ownable(msg.sender) ERC721("Rolex Yacht-Master 40", "") {}

    function mint() public onlyOwner returns (uint256) {
        if (_minted) {
            revert NFTAlreadyMinted();
        }
        _safeMint(owner(), 0);
        _minted = true;
        return 0;
    }
}
```

{% endcode %}

</details>

Then, compile the project using [`forge build`](https://book.getfoundry.sh/reference/forge/forge-build.html):

<pre class="language-sh"><code class="lang-sh"><strong>forge build
</strong>
[⠰] Compiling...
[⠔] Compiling 38 files with Solc 0.8.27
[⠒] Solc 0.8.27 finished in 1.01s
Compiler run successful!
</code></pre>

## Deploy your Contract

Follow the instructions on in the ["Deploying" documentation](https://book.getfoundry.sh/forge/deploying) and set your `PLUME_RPC_URL` environment variable similar to the ETH RPC URL. The below command will deploy the sample smart contract provided above on **Plume Testnet** for instance (switch the RPC and verifier URL to Mainnet to deploy on Plume Mainnet).

{% code overflow="wrap" %}

```sh
export PLUME_RPC_URL=https://testnet-rpc.plume.org
export CONTRACT_PATH=<contract_file>:<contract_name>

forge create $CONTRACT_PATH \
    --rpc-url $PLUME_RPC_URL \
    --broadcast \
    --legacy --interactive
```

{% endcode %}

{% hint style="info" %}
To verify the contract while deploying, use `--verify`  flag, more details [here](https://book.getfoundry.sh/forge/deploying).
{% endhint %}

The below command will verify the contract and deploy it simultaneously.

```sh
export PLUME_RPC_URL=https://testnet-rpc.plume.org
export VERIFIER_URL=https://testnet-explorer.plume.org/api/
export CONTRACT_PATH=<contract_file>:<contract_name>

forge create $CONTRACT_PATH \
    --rpc-url $PLUME_RPC_URL \
    --verify \
    --verifier blockscout \
    --verifier-url $VERIFIER_URL \
    --broadcast \
    --legacy --interactive
```

{% hint style="warning" %}
Make sure to replace the details in the `<contract_file>:<contract_name>` with your contract details.
{% endhint %}
