tldr; Ethereum’s memepool is a database of unconfirmed or pending transactions. Bots are created specifically to monitor transactions that they can front-run and profit from. Searchers use their bots to detect profitable transaction opportunities (arbitrage) in the ETH chain and submit these transactions to the network. This has led to an increase in transaction fees, which has a ripple effect.
