CoW DAO is on a mission to protect Ethereum users from MEV and optimize trade execution across DeFi. We achieve this through the CoW Protocol, CoW Swap (a leading intent-based DEX aggregator), and the innovative MEV Blocker, which together help secure, aggregate, and route trades for optimal outcomes. We also fund values-aligned projects via the CoW Grants Program.

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).

With over 100 open-source repositories on GitHub, we're transparent, community-driven, and deeply committed to the open-source ethos. Our real-time Dune Analytics dashboard showcases billions in cumulative trading volume and a rapidly growing user base. As we continue to scale, CoW DAO remains at the forefront of DeFi innovation, prioritizing security, efficiency, and decentralization.

At Aztec, our goal is to add privacy to Ethereum.

In the current public blockchain paradigm, users and entities unknowingly broadcast data in the public, compromising privacy and security to get trustlessness.

Not only are unencrypted blockchains inherently privacy-exposing, they require significant redundancy to compute and verify the legitimacy of transactions.

Implementing scalable encryption in a public blockchain paradigm requires cutting-edge math and engineering. Thankfully, our team of scientists and engineers invented Plonk, the industry-standard zkSNARK, and Noir, the universal language of zero knowledge.

Now, we’re building a first of its kind Layer 2 with private smart contracts. This requires new cryptographic primitives, a zero-knowledge DSL for writing contracts, a privacy-friendly execution environment, a carefully designed set of circuits that prove the validity of the chain to L1, a decentralized block-building and proving mechanism, and a top-tier user and developer experience. And it’s now time to bring it to market.

We’ve raised $125 million from industry-leading investors including a16z crypto, Paradigm, Variant, Consensys, and a_capital, and we’re growing quickly.

Lido is a liquid staking protocol backed by industry-leading staking providers that supports staking for Ethereum. Lido lets users stake their tokens - without locking tokens or maintaining infrastructure - whilst participating in on-chain activities, e.g. lending, farming and more.
