You must first have a smart contract development environment, usually Solidity, in order to implement a flash loan arbitrage bot. When creating a flash loan arbitrage bot through crypto flash loan bot development company, use APIs to connect the bot to decentralized exchanges (DEXs) and configure a smart contract to manage loan borrowing, trading, and repayment. To make sure it functions properly in spotting arbitrage opportunities and completing transactions within a single block, thoroughly test on a testnet. After validation, make it available for live trade on a mainnet such as Ethereum or Binance Smart Chain.
