Flashloaner

Educational flash loan smart contracts and tooling built with Hardhat. This repository demonstrates Uniswap V2-style flash swaps and related patterns for research and learning purposes.

Overview

This project provides a minimal yet practical setup to explore flash loans/flash swaps. It focuses on safe developer workflows (compilation, testing, and local deployments) while keeping the smart contract code approachable.

What's Included

• Contracts
  • contracts/FlashLoaner.sol: Example flash swap/flash loan executor.
  • contracts/UniswapV2Library.sol: Minimal helpers adapted for Uniswap V2 interactions.
  • contracts/interfaces/*: Lightweight interfaces for ERC-20 and Uniswap V2 components.
• Tooling
  • Hardhat configuration (hardhat.config.ts)
  • TypeScript support (tsconfig.json)
  • NPM scripts (package.json)

Prerequisites

• Node.js LTS (recommended) and npm or yarn
• Git

Quick Start

1. Install dependencies

npm install
# or
yarn

2. Compile contracts

npm run compile

3. Run tests

npm test

4. Start a local node (optional)

npm run node

5. Deploy to a network (example: localhost)

npm run deploy -- --network localhost

Adjust the --network flag in line with your Hardhat network settings.

Configuration

Populate any required environment variables (e.g., RPC URLs, private keys) for deployments. A common approach is to use a local .env file and load it in hardhat.config.ts (dotenv). Ensure you never commit secrets to version control.

Usage Notes

• This repository is for learning and experimentation. Flash loans are advanced and risky.
• The example FlashLoaner contract assumes Uniswap V2-compatible pairs. Adapt addresses and logic for your target network.
• Thoroughly review and extend unit tests before attempting any non-local deployment.

Security & Risk Disclaimer

• Not audited. Use at your own risk.
• Do not deploy to production networks without a professional audit and extensive testing.
• Flash loan strategies can be economically brittle and highly sensitive to MEV and slippage.

Roadmap

• Expand documentation with detailed walkthroughs.
• Add more test coverage and scenario examples.
• Provide multiple DEX/AMM examples for comparison.
