More than 30 Ethereum projects including Safe, BitKeep, DODO, Oasis, Balancer, and 1inch have cooperated to launch MEV Blocker RPC, a tool designed to protect users from various types of MEV attacks. MEV Blocker RPC is a tool that routes user transactions to a network of "searchers" rather than the public mempool. These searchers bid for the right to run transactions in reverse, helping users protect against front-running and sandwich attacks.
