Over 27 prominent Ethereum projects joined hands to launch MEV Blocker, a solution that aims to tackle and minimize the amount of value extracted from their users — aka maximally extractable value (MEV), Ethereum’s invisible tax.
MEV is a tax imposed on decentralized finance (DeFi) users on transactions. MEV bots can hijack transactions midway, such as Ether (ETH) trades, nonfungible token (NFT) purchases and Ethereum Name Service registrations, and inflate prices for the users. MEV Blocker was jointly developed by CoW Swap, Agnostic Relay and Beaver Build as a free and censorship-resistant tool to counter this “$1.3 billion dollar problem” persistent across the Ethereum ecosystem.
