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…
CoW DAO Core Team Proposes Value Distribution Framework
The CoW DAO core team has published their perspective on value distribution mechanisms for the protocol. **Key Points:** - Proposal builds on community research and feedback - Developed in collaboration with Aragon Project - Responds to the Value Distribution Mechanism RFP - Now open for community discussion on the forum The framework represents a significant step in determining how value flows through the CoW Protocol ecosystem. Community members are invited to review and provide input on the [proposal](https://forum.cow.fi/t/cow-daos-path-to-value-distribution-core-team-view/3454).
CoW Protocol Launches Atomic Bundles for Multi-Step DeFi Workflows
CoW Protocol has introduced **Atomic Bundles**, a framework that combines solver-settled swaps with downstream protocol actions in a single coordinated flow. **Key features:** - Sign one intent, solvers handle execution automatically - Enables multi-step workflows across lending, vaults, and treasury management - Position updates follow automatically without manual intervention - Now available on Euler The framework allows users to execute complex DeFi operations where the swap component is handled by CoW Protocol's execution layer, while subsequent actions (like depositing into lending protocols) happen atomically.

Euler Finance Integrates CoW Protocol for MEV-Protected Lending Swaps

Euler Finance has integrated CoW Protocol to improve execution on lending operations that involve token swaps. **Key features:** - Lending actions like borrowing, swapping collateral, and debt repayment now route through CoW Protocol - Solvers compete to find optimal execution prices - Built-in MEV protection for all swap operations - Position updates happen automatically **Why it matters:** Most DeFi lending operations include a swap component - whether borrowing one asset to swap for another, or selling collateral to repay debt. Poor execution on these swaps directly impacts the final outcome of lending positions. The integration allows users to multiply positions, swap collateral, and repay debt with competitive pricing and protection from MEV extraction, all within a single flow.

CoW Protocol Compensates Users After Security Incident
CoW Protocol announced it will compensate affected users following a security incident, despite the failure not originating from their platform. The protocol emphasized its commitment to user trust and taking responsibility for the impact on their community. **Key Points:** - Protocol will make affected users whole financially - Security failure occurred outside CoW Protocol's systems - Decision reflects company's prioritization of user relationships - Continues focus on community security and well-being The move demonstrates accountability in the web3 space, where protocols often face difficult decisions about compensation when third-party vulnerabilities affect their users.
