Jito Labs, a developer for the Solana blockchain, announced the suspension of its mempool functionality offered through the Jito Block Engine, citing negative externalities that impacted users. This decision, made after deliberate conversations with the Jito Labs team and key stakeholders, including the Solana Foundation, comes in the wake of concerns over MEV (Miner Extractable Value) issues. Notably, sandwich attacks, which have been costly to traders, particularly BODEN traders who were getting "sandwiched to hell." The suspension is seen as a positive development for end users and bullish for Solana. Additionally, Solana's DEX Jito had seen a significant increase in tip revenue, reaching 9.32k SOL (valued at $1.2 million) on March 6, setting a new high. However, the platform faced a serious MEV Bot problem, including a vulnerability that allowed fake tips, affecting normal user transactions. Solana users were extracted at least 50K $SOL last week through MEV, amounting to $550M annualized, highlighting the severity of the issue.
