    * First Milestone Given an atomic transaction ID, we need an API call that returns whether it is profitable to copy/imitate that transaction in the current time. is one example of these transactions. The guy who did this transaction started with 0.027497 BNB, swapped them to Kinka token via Pancakeswap, then sold them on Apeswap and ended up with 0.029699 BNB. The profit from this transaction is around 0.002 BNB. We will be probing transactions on BSC to avoid high gas fees. I will ask you to deploy this API somewhere to be able to call it without knowing the code yet. You'll give us at least two days where we will test your API against multiple transactions.

    I recently had a Metamask trading bot coded that has been found to be malicious. The bot would accept deposits, function properly, but not withdraw. I've already lost quite a bit to this scam. This story only gets worse so I'll keep those details to myself but if you're interested, I will share. This project has a very short timeframe because just because we were scammed doesn't mean creditors understand the situation. My family and I need someone to be our white knight or white hat hero - whatever you want to call it. I am looking for someone who can make, from scratch, a front running, arbitrage, or other passive income bot that can help us while I recover, find a new job, and try to recover our stolen savings. The key part is that I want you to create for me wha...
