Record High for BNB Chain Blocks Affected by ‘Sandwich Bots’

In November, 35.5% of blocks in the EVM-compatible BNB Chain were subjected to ‘sandwich attacks’, marking a record level. This is indicated by data from a dashboard on Dune.

During the week from November 17 to 25, 645 active MEV bots were recorded on the blockchain. Their actions affected 43,397 traders—6.2% of the total number.

The total trading volume on DEX on BNB Chain for the period was $9.23 billion. ‘Sandwich bot’ operations accounted for $1.32 billion, targeting transactions worth $1.5 billion.

Ethereum co-founder Vitalik Buterin has repeatedly addressed the issue of MEV, describing the technology as one of the three major threats to the network’s decentralization. According to him, a limited number of solution operators unfairly capture value that should belong to all users.

In July, the Solana Foundation expelled a group of validators from its delegation program for participating in ‘sandwich attacks’. It was later revealed that the majority of the owners of the blocked nodes were Russian citizens.

As reported, a well-known MEV bot on Solana earned approximately $30 million from user transaction arbitrage in just two months.

However, manipulations are not always effective. In September, software took a flash loan of $11.7 million for a ‘sandwich attack’ on a Shuffle (SHFL) token transaction worth $5,000. The bot executed 14 transactions across various DeFi platforms and gained a profit of $20.
