## Foundry

Foundry is a smart contract development toolchain.

With Foundry you can manage your dependencies, compile your project, run tests, deploy smart contracts, and interact with the chain from the command-line and via Solidity scripts.

Check out the [<mark style="color:purple;">Foundry Book</mark>](https://book.getfoundry.sh/) to get started with using Foundry with Kinto.

***

### Using Foundry with Kinto

Foundry supports Kinto out of the box. To install Foundry, you can just follow the instructions [<mark style="color:purple;">here</mark>](https://github.com/ethereum-optimism/optimism-tutorial/tree/main/getting-started#foundry).

Provide the Kinto RPC URL and Chain ID when deploying and verifying your contracts.

#### Deploying a smart contract[​](https://docs.base.org/tools/foundry#deploying-a-smart-contract) <a href="#deploying-a-smart-contract" id="deploying-a-smart-contract"></a>

```
forge create ... --rpc-url=$KINTO_RPC_URL
```

#### Verifying a smart contract[​](https://docs.base.org/tools/foundry#verifying-a-smart-contract) <a href="#verifying-a-smart-contract" id="verifying-a-smart-contract"></a>

```
//Example of contract verification in our blockscout
  
  forge verify-contract 
    0xdb791AF345A21588957E4e45596411b2Be2BD4cd 
    src/sample/Counter.sol:Counter 
    --verifier-url https://explorer.kinto.xyz/api  
    --verifier blockscout

```

## Hardhat

Hardhat is a development environment for extensible and rapid smart contract development.

You can use Hardhat to modify, build, debug, and deploy your smart contracts to Kinto.

To setup Hardhat, follow the instructions [<mark style="color:purple;">here</mark>](https://github.com/ethereum-optimism/optimism-tutorial/tree/main/getting-started#hardhat).

Now, access a hardhat terminal:

```
yarn
yarn hardhat console --network kinto
```

***

### Using Hardhat with Kinto

To configure [<mark style="color:purple;">Hardhat</mark>](https://hardhat.org/) to deploy smart contracts to Kinto, update your project’s `hardhat.config.ts` file by adding Kinto as a network:

But make sure that your *<mark style="color:orange;">hardhat.config.js</mark>* includes the kinto network

```javascript
module.exports = {
  solidity: "0.8.13",
  networks: {
    "kinto": {
      url: "https://kinto-mainnet.calderachain.xyz/http",
      accounts: ['youraccountprivatekeygoeshere'],
      gas: 10000000
   },
  }
};
```

***

## Truffle

Truffle is a comprehensive suite of tools for smart contract development.

Truffle can quickly build, test, debug, and deploy your smart contracts to Kinto.

***

### Using Truffle with Kinto

To configure [<mark style="color:purple;">Truffle</mark>](https://trufflesuite.com/docs/truffle/) to deploy smart contracts to Kinto:

1. Install Truffle by running the following command:

   ```
   npm install -g truffle
   ```
2. Create a new Truffle project by running the following command:

   ```
   truffle init
   ```
3. Update your project's `truffle-config.js` file by adding Kinto as a network:

   ```
   const HDWalletProvider = require('@truffle/hdwallet-provider');

   module.exports = {
     networks: {
       'kinto': {
         provider: function () {
           return new HDWalletProvider('MNEMONIC', 'https://kinto-mainnet.calderachain.xyz/http
   ');
         },
       },
     },
   };
   ```
4. Compile and deploy your smart contract by running the following command:

   ```
   truffle migrate --network kinto
   ```
