Forta Hardhat Plugin

This is a Hardhat plugin that integrates Forta Agent development tools 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. To learn more about Forta, check out the docs here.

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

require("hardhat-forta");

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

import "hardhat-forta";
