# Forta Hardhat Plugin

[![npm version](https://badge.fury.io/js/hardhat-forta.svg)](https://badge.fury.io/js/hardhat-forta)

This is a Hardhat plugin that integrates [Forta Agent development tools](https://docs.forta.network/en/latest/cli/) enabling teams to quickly add security/operational monitoring for their smart contracts. You can either start from a sample agent project, or initialize from an existing [template](https://github.com/arbitraryexecution/forta-agent-templates). To learn more about [Forta](https://forta.org/), check out the docs [here](https://docs.forta.network).

## Installation

You can install the Forta plugin to your Hardhat project using the following command

```
npm install -D hardhat-forta
```

This will install the Forta plugin as a dev dependency in your `package.json`. The last step is to update your `hardhat.config.js` file to import the plugin by adding the following line

```javascript
require("hardhat-forta");
```

Or if you are using TypeScript, in your `hardhat.config.ts`:

```ts
import "hardhat-forta";
```

module.exports = {

  },
};
```
