What is Flashloan Arbitrage Bot?

A Flashloan Arbitrage Bot is an automated trading tool designed to exploit price differences across decentralized exchanges (DEXs) by using flash loans. Flash loans are uncollateralized loans provided by platforms like Aave, which must be borrowed and repaid within a single transaction. The bot identifies arbitrage opportunities where a digital asset is priced differently on two or more DEXs, enabling it to buy low on one exchange and sell high on another, profiting from the price discrepancy.
