The Solana Foundation has announced that multiple validator operators will be removed from its accreditation program due to their involvement in malicious sandwich attacks on Solana users.
"The decision on this matter is final. We will continue to detect operators involved in sandwich attacks and take enforcement action." Tim Garcia, head of validator relations at the Solana Foundation, said on the Solana Foundation's Discord.
Enforcement to protect Solana users
Mert Mumtaz, co-founder of Solana RPC provider Helius, explained that this move ensures that the foundation will not delegate SOL tokens to validators involved in harmful activities such as sandwich attacks. These attacks are serious violations of Solana Foundation rules.
Learn about sandwich attacks
A sandwich attack is a front-running exploit in which an attacker profits from manipulating prices by placing one transaction before and after the victim's transaction. Such an exploit would not only harm individual users, but also undermine the trust and efficiency of the Solana network.

Centralized clampdown on malicious activity
Tim Garcia, head of validator relations, said: “Operators who engage in malicious activity, such as engaging in private mempool transactions for sandwich attacks or otherwise harming Solana users, will not be tolerated. Anyone found to be involved in such activity will not be tolerated. will be excluded from the program and any delegated pledges from the Foundation will be immediately and permanently removed."
What is the Solana Foundation Delegation Program?
The Solana Foundation Delegation Plan is supported by delegating SOL tokens to validators, allowing them to reduce the need for tokens when operating pledge nodes. But the verifier must abide by certain specifications.
How to solve the MEV problem on Solana
Solana Maximum Extractable Value (MEV) issues include front-running and sandwich attacks, and the Solana Foundation is warning by withdrawing sponsorship. Although some communities believe that interfering with MEV behavior on the chain is a centralized approach, the Solana Foundation uses the method of withdrawing delegation to deter it. It will not prevent malicious actors from serving as nodes. It can also be regarded as a passive user protection action. .
