MEV Blocker Starts Earning Revenue from Builders, Remains Free for Users
🐮 MEV Blocker's New Chapter
MEV Blocker, a product launched by CoW DAO a year ago to protect users from maximal extractable value (MEV) attacks, has reached an important milestone. As per CIP-40, MEV Blocker has started earning revenue from builders, allowing CoW DAO to continue supporting the product while keeping it completely free for users. Since its launch, MEV Blocker has rebated almost 1750 ETH to users, with a median refund of 0.007 ETH (approximately $24). It has defined a new category of user-protective RPC endpoints known as 'mev blockers.' MEV attacks are considered theft, and MEV Blocker aims to protect users from such attacks as a public good.
Today marks an important milestone in the evolution of MEV Blocker. Per CIP-40, MEV Blocker is now earning revenue from builders. This allows CoW DAO to continue its support for MEV Blocker and – most importantly – keeps the product completely FREE for users.
🗳️ CIP-40 asks whether MEV Blocker should start charging a fee to builders to use the service. Importantly, the proposed fee mechanism keeps MEV Blocker 100% free for users. Vote on CIP-40 here 👉 snapshot.org/#/cow.eth/prop…
