The developer of the Solana client stopped the mempool due to MEV attacks on network users
Jito Labs has announced the termination of its mempool. The Solana client developer company has disabled the feature due to the increased frequency of MEV attacks on network users.
The developer of the Solana client, represented by Jito Labs, announced the closure of its mempool. The reason for the decision was the increased frequency of MEV attacks on network users.
A mempool is a temporary storage for transactions waiting to be included in the blockchain. Unscrupulous users have learned to use this technology to carry out so-called MEV attacks, also known in the community as "sandwich attacks".
During the implementation of such an operation, a bet is placed on special bots that track memes with pending transactions. When the software detects a large transaction, it creates two trading operations: one before the detected transaction, and the other after.
Thus, the bot forms a trap with price slippage. As a rule, users lose most of the amount appearing in the initial transaction. At the same time, MEV attacks are not considered illegal.
The Solana network does not have its own mempool, which made unscrupulous transactions of this kind impossible. However, Jito Labs launched its Solana-based blockchain, which had the mentioned function. As a result, unscrupulous traders have been able to carry out attacks on users.
"Jito Labs has decided to suspend the work of the mempool offered through the Jito blockchain due to negative external consequences for Solana users. This step was taken after careful discussion with the team and key participants in the Solana ecosystem," the company said in a statement.
