 In the first series, we will introduce how to conduct an on-chain analysis, and then we will reproduce on-chain attack(s). This skill will aid us in understanding the attack process, the root cause of the vulnerability, and even how the arbitrage robot arbitrages!
 
 ## Tools can greatly improve efficiency

 Before getting into the analysis, allow me to introduce some common tools. The right tools can help you do research more efficiently.

-Transaction Viewer is the most commonly used tool, it is able to list the stack trace of function calls and the input data in each function during the transaction. Transaction viewer tools are all similar; the major difference is the chain support and auxiliary functions support. I personally use Phalcon and Sam’s Transaction Viewer. If I encounter unsupported chains, I will use Tenderly. Tenderly supports most chains, But the readability is limited, and analysis can be slow using its Debug feature.

 We will look at JayPeggers - Insufficient validation + Reentrancy [Incident](https://github.com/SunWeb3Sec/DeFiHackLabs/#20221229---jay---insufficient-validation--reentrancy) as an example transaction [TXID](https://phalcon.blocksec.com/tx/eth/0xd4fafa1261f6e4f9c8543228a67caf9d02811e4ad3058a2714323964a8db61f6) to dissect.
 
 First I use the Phalcon tool developed by Blocksec to illustrate. The basic information and balance changes of the transaction can be seen in the figure below. From the balance changes, we can quickly see how much profit the attacker has made. In this example, the attacker made a profit of 15.32 ETH.

 Etherscan has a built-in decompilation feature, but the readability of the result is often poor. Personally, I often use Dedaub, which produces better decompiled code.
