We also fund values-aligned projects via the CoW Grants Program.</p><p style="min-height:1.5em">CoW Protocol is consistently ranked among the top DEX aggregators by monthly volume and is the largest intent-based exchange. Our MEV Blocker protects trades from harmful MEV extraction and is integrated across the Ethereum ecosystem. The CoW AMM is the only live AMM designed to protect liquidity providers from LVR (loss-versus-rebalancing).</p><p style="min-height:1.5em">With over <strong>100 open-source repositories</strong> on <a target="_blank" rel="noopener" href="https://github.com/cowprotocol">GitHub</a>, we're transparent, community-driven, and deeply committed to the open-source ethos.
