@vechain/sdk-hardhat-plugin

Welcome to the hardhat-plugin package of the VeChain SDK!

Introduction

The VeChain SDK Hardhat plugin bridges the gap between Hardhat and the VeChain SDK, providing developers with a seamless interface. This versatile package is essential for smart contract development on the VeChainThor blockchain.

Key Features

This plugin simplifies the creation, testing, deployment, and interaction with smart contracts. It allows developers to build robust decentralized applications (dApps) and services on VeChainThor. By integrating the VeChain SDK into Hardhat, developers can leverage VeChain's powerful blockchain infrastructure within the familiar Hardhat development environment.
