Key points:

Profits from sandwich attacks on Ethereum have dropped sharply, although their number has remained the same.
More and more attacks are targeting stablecoin pools, creating risks for users.
The decline in profitability may indicate that MEV protection tools are working effectively.

In 2025, the activity of decentralized exchanges on Ethereum experienced significant growth: the monthly trading volume rose from $65 billion to over $100 billion. But against the backdrop of this growth, one of the main threats to the network — sandwich attacks — began to generate much less revenue for attackers.

According to EigenPhi, profits from such attacks fell from nearly $10 million at the end of 2024 to approximately $2,5 million by October 2025. At the same time, their number remains the same — from 60 000 to 90 000 per month.

This shows that attacks have not disappeared, but their effectiveness has declined significantly: the average income is now only about $3 per attempt. Only six attackers earned more than $10 000 per year, highlighting the overall decline in profitability.

Why has activity in stablecoin pools increased

In 2025, about 38% of all sandwich attacks targeted low-volatility pools, including stablecoins and wrapped assets. About 12% of attacks targeted low-slippage stablecoin pools, where users typically expect the most predictable transaction outcomes. The growing concentration of liquidity and stable pricing make such pools an attractive target for bots.

Previously, such pools were considered safer, but now attackers are increasingly targeting them.

The decline in overall profits may indicate a positive trend — the growing use of MEV protection tools. They hide transaction data or change the order in which they are processed, preventing bots from executing “sandwich strategies.” Solutions such as Flashbots, private relays, and privacy features in DEXs help reduce risks for traders.
