Optimus Prime Arbitrage Bots

This repository contains two smart contracts designed to execute cross-DEX arbitrage strategies between Uniswap V3 and PancakeSwap V3 on EVM chains (tested on Arbitrum).

• OptimusPrime → arbitrage without flash loans (requires pre-funded tokens).
• FlashOptimusPrime → arbitrage with Uniswap V3 flash loans (capital efficient).

Both contracts implement role-restricted access (owner, trade executor), profit checks, and event emissions.
