    We are looking for an expert. Long term experience with sniping and trading bots is a must. Here is what the bot has to do: It needs to snipe the same block the liquidity got added. Not the next one. It will always need to buy on the absolutely first block, before all market competitors. So, the bot will: - Scan the blockchain and find transactions based on certain criteria (pending on the block aka mempool). - Speed of the bot is of absolute paramount importance. No more than 0.01 seconds. - Sell function needs to be able to set X amount of BNB, after X amount of profit. - Buy function needs to be able to stop the trade/ snipe if first block is missed, OR set to maximum "X" amount of marketcap. - Gas fee and slippage needs to be able to be set.
