“Additionally, we attempted to engineer solutions to reject sandwich bundles, but our solutions became a cat-and-mouse game with MEV searchers,” the statement said. “Ultimately the Jito Labs team views negative MEV, including sandwich attacks, as a drag on the Solana ecosystem, and in the absence of an engineering solution we have made the difficult decision to suspend the mempool. We remain dedicated to providing an additional revenue stream for validators and stakers in addition to making Solana the best execution environment for all users.”
