Solana Foundation Eliminates Malicious Validators to Combat Sandwich Attacks

• Solana network has encountered serious disruptions from sandwich bots for an extended duration.
• The Solana Foundation has taken corrective measures by removing certain validator operators from its delegation program.
• The foundation aims to safeguard users and maintain network integrity by addressing these security concerns.

Solana Foundation’s Decisive Move

Tim Garcia, Solana Validator Relations Lead, announced on the official Discord channel that the action against validators involved in malicious activities is definitive. He emphasized that the foundation would continue to take strict enforcement measures against operators engaging in mempool activities facilitating sandwich attacks.

“Anyone found engaging in such activity will be rejected from the program, and any stake from the Foundation will be immediately and permanently removed.”

Mert Mumtaz, co-founder of Helius, a Solana RPC provider, indicated that this initiative aims to prevent foundation delegation to validators executing harmful attacks against retail users.

According to Mumtaz, sandwich attacks represent a particularly harmful form of Maximal Extractable Value (MEV) exploit, where retail users are disadvantaged by receiving the worst possible trade prices, allowing the attacker to reap all the profits. Despite Solana’s inherent design to repel such attacks, certain validators have altered their operations to enable these malicious activities.

He also noted that other staking pools will likely adopt similar measures in the near future to combat sandwich attacks.

Understanding “Sandwich Attacks”

Sandwich attacks are one of the most prevalent forms of MEV attacks. Bots monitor the Solana network for potential token purchases by users. These bots then place a sizable order ahead of the user, causing the token’s price to spike.

As the user’s order is executed at the inflated price, the bots sell their tokens at this new higher price, thus profiting substantially at the user’s expense.

Future Implications

The Solana Foundation’s current efforts underscore a broader commitment to network security and integrity. These measures protect users from exploitation and encourage a safer trading environment. The decisive action against sandwich attacks serves as a signal to the broader crypto community about the importance of combating malicious activities effectively.

Conclusion

The Solana Foundation’s efforts to remove validators engaging in sandwich attacks highlight a robust approach to maintaining network security. By taking firm action against these bad actors, the foundation aims to protect retail users and uphold the trust within the Solana ecosystem. Moving forward, such stringent measures may set a precedent for other networks to follow in combating MEV attacks.
