Solana Significantly Reduces Sandwich Attacks: A Major Step Forward for Traders?

Max Resnick – Chief Economist at Anza – has just revealed some positive news: the rate of sandwich attacks on #solana has drastically decreased compared to last year.

Previously, sandwich attacks were a significant issue for Solana as its fast processing speed inadvertently enabled bad actors to 'frontrun' and 'backrun' orders, profiting from users' transactions.

At the beginning of 2024, the Jito platform had temporarily disabled the mempool to prevent sandwiching, and the Solana Foundation also aggressively removed questionable nodes from the staking program. However, these measures did not completely resolve the issue as bad actors could easily 're-emerge' with new identities.

According to Resnick, the most effective solution comes from improving Solana's core code. When the 'targeting' mechanism is optimized, the number of validators seeing each transaction significantly decreases. If a validator holds only 10% of the stake, they will only see about 10% of transactions – limiting manipulation opportunities.

Data from #ghost shows that profits from sandwich attacks on Solana have noticeably decreased in March and April 2025 compared to the same period last year, even though network revenue (REV) remained unchanged. Marinade – the largest stake pool provider – has also started penalizing validators involved in sandwich attacks through stake auctions.

These changes are expected to create a safer environment for the Solana trading community.
