Ethereum Smart Contracts for Arbitrage and Flash Loans

This repository contains Ethereum smart contracts for performing arbitrage trading and utilizing flash loans on decentralized finance (DeFi) platforms.

Contracts Overview

1. Arbitrage.sol

Description:

The Arbitrage.sol contract facilitates automated arbitrage trading between Uniswap and Sushiswap DEX platforms.

Features:

  • Automated Trading: Executes trades based on predefined parameters to exploit price differences between Uniswap and Sushiswap.
  • Slippage Tolerance: Adjustable slippage tolerance ensures trades are executed profitably within specified parameters.
  • Owner Controls: Allows the contract owner to adjust slippage tolerance and withdraw tokens.

2. FlashLoan.sol

Description:

The FlashLoan.sol contract demonstrates how to execute a simple flash loan using the Aave protocol.

Features:

  • Flash Loan Execution: Requests and handles flash loans from the Aave protocol.
  • Trade Execution: Example functionality swaps the flash loaned asset for WETH using Uniswap V2.
  • Owner Controls: Allows the contract owner to execute flash loans and handle loan repayments.

3. Flash-Loan-Arbitrage.sol

Description:

The Flash-Loan-Arbitrage.sol contract integrates flash loans with arbitrage trading strategies, utilizing Uniswap V2 for enhanced trading opportunities.

Features:

  • Combined Strategies: Executes arbitrage opportunities using flash loans from the Aave protocol and trading on Uniswap V2.
  • Customizable Logic: Demonstrates advanced trading strategies while leveraging flash loan capabilities.
  • Owner Controls: Allows the contract owner to execute complex trading and manage flash loan repayments.

Usage

Prerequisites

  • Ensure you have access to an Ethereum node or provider like Infura.
  • Use a development environment like Remix or Truffle for local testing and deployment.

Deployment

  1. Deploy contracts on an EVM-compatible network (e.g., Ethereum mainnet, Polygon, Arbitrum, Mumbai testnet).
  2. Set appropriate permissions and parameters as defined in each contract's constructor.

Interacting with Contracts

  • Use Ethereum wallets or scripts to interact with deployed contracts.
  • Follow specific contract methods like performArbitrage in Arbitrage.sol, executeOperation in FlashLoan.sol, or integrated methods in Flash-Loan-Arbitrage.sol.

Risks

  • Market Risks: Arbitrage and flash loan trading carry inherent market risks, including price volatility and slippage.
  • Contract Risks: Smart contract interactions are irreversible; ensure parameters and transactions are validated thoroughly.
