This repository contains a collection of basic examples demonstrating how to deploy and interact with Ethereum-compatible smart contracts on Polkadot Hub using Hardhat and REVM (Rust Ethereum Virtual Machine). These examples showcase best practices for smart contract development in a modern Hardhat environment.
This repository contains the following example projects:
- basic-hardhat - minimal
Storagecontract deployment using Hardhat — the ideal starting point - erc20-hardhat - implementation of an ERC-20 token contract using Hardhat
- uniswap-v2-core-hardhat - Uniswap V2 core protocol (factory, pair, AMM) using Hardhat
- uniswap-v2-periphery-hardhat - Uniswap V2 periphery contracts (Router01, Router02, WETH9) using Hardhat
- uniswap-v3-core-hardhat - Uniswap V3 core protocol (factory, concentrated-liquidity pool) using Hardhat
- uniswap-v3-periphery-hardhat - Uniswap V3 periphery contracts (SwapRouter, NonfungiblePositionManager) using Hardhat
Each subfolder is a standalone Hardhat project with its own configuration, contracts, deployment scripts, and tests.

Clone this repository
git clone https://github.com/polkadot-developers/revm-hardhat-examples.git cd revm-hardhat-examples -
Navigate to any of the example directories
cd erc20-hardhat
Each example folder contains its own README with specific instructions and explanations for that particular smart contract implementation.
For comprehensive guidance on deploying contracts to REVM using Hardhat, visit the Hardhat Development Environment page in the official Polkadot documentation. This resource provides step-by-step instructions, configuration details, and best practices for smooth integration.
