“We also attempted to design a solution that rejected sandwich bundling, but our solution became a cat-and-mouse game with MEV searchers,” the statement said. “Ultimately, the Jito Labs team views negative MEVs, including sandwich attacks, as an obstacle to the Solana ecosystem and, in the absence of an engineering solution, has made the difficult decision to discontinue the mempool. We are committed to providing additional revenue streams. In addition to making Solana the best execution environment for all users, it is also for validators and stakers.”
