This section will guide you through writing and testing FHEVM smart contracts in Solidity using Hardhat.

The FHEVM Hardhat Plugin

To write FHEVM smart contracts using Hardhat, you need to install the FHEVM Hardhat Plugin in your Hardhat project.

This plugin enables you to develop, test, and interact with FHEVM contracts right out of the box.

It extends Hardhat’s functionality with a complete FHEVM API that allows you:

• Encrypt data

• Decrypt data

• Run tests using various FHEVM execution modes
