Exploring Flash Loan Triangular Arbitrage Opportunities on PancakeSwap: Part I Static Analysis

Flash loans have gained significant popularity in the decentralized finance (DeFi) space. They allow users to borrow an amount of assets without any collateral, as long as the borrowed amount is returned within the same transaction. When used correctly, flash loans can create unique arbitrage opportunities.

When writing a flash loan contract, several important factors need to be considered. Inside the contract, the user might send a flash loan to a unique address, which acts as the lender. The flash loan can be done through a function called `flashLoan`. This function will be executed on a certain market, for example PancakeSwap, and the parameters of the flash loan will include the initiator, the asset to be borrowed, and the amount.

PancakeSwap is a decentralized exchange (DEX) on the Binance Smart Chain (BSC) that offers a variety of trading pairs. The flash loan contract setup​ might involve initiating a flash loan on PancakeSwap by deploying a contract on the BSC. The flash loan contract must be suitable for the BSC chain and its memory and functionality, including the flash loan functionality itself. This ensures that the flash loan can be executed properly.

Static analysis is the first step in assessing the code of a flash loan contract. It involves reading and analyzing the code to identify any potential risks or vulnerabilities. The main risks in flash loan contracts come from the non-used loans​ and the cyclical read and write logic. To perform a static analysis, the code should be copied and analyzed outside of the chain environment.

By conducting a static analysis, developers can identify any potential risks and address them before the contract is deployed on the blockchain. This analysis is crucial to ensure the security and effectiveness of the flash loan contract. It allows developers to understand the logic of the code, the theoretical execution flow, and any additional steps or checks that need to be implemented.

In the next part of this series, we will dive deeper into the flash loan contract analysis and explore the dynamic analysis, which involves executing the contract and analyzing the transaction flow. Stay tuned!
