    Looking for someone to create a bot that detects when new liquidity is added to an AMM (automated market maker) pool on PancakeSwap & Uniswap. The bot allows me to buy any newly added token from PancakeSwap and Uniswap in amazing speeds (up to zero seconds from the time of the listing). It is called "sniping". The bot works by: Connecting to the blockchain network, scanning for all mempool / pending transactions, finding and matching the liquidity add transaction of the token you are trying to snipe and then placing the buy order in the same block. Speed is important… MUST be fast!
