Solana Foundation: Some validators conducted "sandwich attacks" against users and have been removed

Golden Finance reported that the Solana Foundation announced that it has removed a group of validator operators from the delegation program due to their involvement in a "sandwich" attack on Solana users. Mert Mumtaz, co-founder of Solana RPC provider Helius, explained that this move will ensure that the foundation will not delegate to validators that conduct malicious sandwich attacks on retail users.
