    * 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. If the similar transaction deems to be not profitable your code will test with a smaller amount and return the prof...

    I have a Nodejs bot that is buying newly launched Tokens on Eth and BSC blockchains based on some set criteria. I need to add the following updates or features: 1) The bot MUST do all SELLS using the gas multiplier 2) Bot should restart if "sellThresholdFall" or "balanceCheckMultiplier" becomes true, or if the Bot Fails to Sell. 3) In Automagic, if useAuthorisedList = True, check "NoRug Endpoint" - a global Variable of Contracts, to see if the contract is on the list, only then buy it. 4) FIX needed = the % tracking is slow to update. Make it faster to track percentage gain. 5) If deadblock is true AND our Buy fails, the bot will listen for the first successful buy trade (from other traders), and sends a buy transaction. 6) If no activity (no buys or sells) f...
