# 2️⃣ Environment setup

Kinto supports Foundry, Hardhat, and Truffe. You can pick one and follow the instructions in [<mark style="color:purple;">this section to install it</mark>](/kinto-the-modular-exchange/building-on-kinto/tools/build-tools.md).

The rest of this documentation assumes Foundry and Forge/Cast.

## 1. Clone the repo

To start, execute git clone for our main repository [<mark style="color:purple;">**kinto-core**</mark>](https://github.com/KintoXYZ/kinto-core)**.**  This repository contains all of the smart contracts of the project and most importantly some scripts and helpers to interact with the chain.

```shell-session
git clone git@github.com:KintoXYZ/kinto-core.git
```

## 2. Installing dependencies and running the tests

Make sure that [<mark style="color:purple;">foundry CLI</mark>](/kinto-the-modular-exchange/building-on-kinto/tools/build-tools.md#foundry) is installed and run the following:

```shell-session
forge test
... when the script finishes, you should see ...

Ran X test suites: Y tests passed, 0 failed, 0 skipped (Z total tests)
```

## 3. Setup your env file&#x20;

Set your .env variables next:

```shell-session
cp .env.sample .env
```

Fill (at least) the following variables:

```json
KINTO_RPC_URL="https://rpc.kinto-rpc.com"
MAINNET_NETWORK_ID="7887"
KINTO_DEV_KEY= //Private key for your deployer EOA
KINTO_WALLET= //Kinto wallet public address
KINTO_WALLET_SIGNER_KEY= //EOA signer of your Kinto Wallet
```

## 4. Setting up a remote chain (optional)

{% hint style="info" %}
You can develop using forge tests directly.

When you are ready to test things in a natural environment, we recommend using Anvil to fork mainnet and work against it.

More information about the complete process can be found on the repositories [README](https://github.com/KintoXYZ/kinto-core/blob/aa/README.md).
{% endhint %}

```
anvil -f <KINTO_REMOTE_URL> --fork-block-number <OPTIONAL_BLOCK>
```

Copy your local fork URL and override KINTO\_RPC\_URL with your fork.&#x20;
