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…
CoW Protocol Proposes New Auction Mechanism
CoW Protocol has initiated voting on CIP-67, a significant proposal to transform their trading mechanism. The proposal aims to replace the current batch auction system with a fair combinatorial auction model. This follows the recent CIP-65 which addressed solver reward allocations for buy orders. - **Key Change**: Transition from batch to combinatorial auctions - **Action Required**: $COW token holders can vote on the proposal - **Voting Link**: [Vote on Snapshot](https://snapshot.box/#/s:cow.eth/proposal/0xf9ecb08c4738f04c4525373d6b78085d16635f86adacd1b8ea77b2c176c99d32)
CoW Protocol Hits New Volume Record in April
CoW Protocol has achieved a significant milestone in April 2025, processing a record-breaking monthly volume of $6.2 billion in trades. This performance represents approximately double the combined volume of all other intent-based trading platforms. Key highlights: - Monthly volume: $6.2 billion - Market position: Leading intent-based trading platform - Performance: Doubled combined volume of competitors For more information about building on CoW Protocol, visit [cow.fi](https://cow.fi/cow-protocol)
Understanding Cross-Chain MEV: Risks and Solutions
MEV (Maximal Extractable Value) has evolved beyond single-chain operations into cross-chain territory, presenting new challenges for traders. Key points: - 5 entities currently control 80% of Ethereum block building - Cross-chain MEV coordination is increasing, potentially affecting trade prices - Users can protect themselves through MEV-resistant RPCs and private transaction pools Emerging solutions: - SUAVE project aims to make MEV more equitable through user compensation - New protocols focus on MEV-resistance and cross-chain protection - Proper slippage settings and MEV protection tools are crucial for critical trades [Learn more about cross-chain MEV](https://cow.fi/learn/understanding-cross-chain-mev)
Study Shows CoW Swap Leads Intent-Based DEXes in Decentralization and Volume
A comprehensive 6-month trading analysis reveals CoW Swap's dominance among solver-based DEXes: - **Higher Trading Volume**: ~$200M daily vs $60M (1inch Fusion) and $30M (UniswapX) - **More Decentralized**: Top solver only controls 25% market share, with next five at ~10% each - **Better for Large Trades**: Shows best execution improvement for trades over 100 ETH The study compared CoW Swap, 1inch Fusion, and UniswapX, finding solver-based DEXes generally outperform traditional alternatives through optimized routing and off-chain liquidity access.
