Kolibrio is a BEV Relay (Broadcaster Extractable Value) that enables transaction broadcasters such as node providers, non-custodial wallets, cross-chain bridges, and dApps to provide a better user experience, enable MEV-cashback, optimize infrastructure, and improve their bottom line. It aims to help transaction originators gain ownership of the order flow they create and have the option to monetize it via a system of on-chain order flow auctions (OFAs).

Rook is an open settlement protocol that leverages the world’s best algorithmic strategists in order to maximize the value of every transaction for protocols, market makers, and traders alike. Rook is providing DeFi with a suite of Keeper-guarded, fully MEV-protected primitives to trade and borrow assets in a safer and more profitable way.Rook’s mission is to provide the infrastructure to make DeFi more secure, egalitarian, and profitable for everyone involved.

Omni-chain DEX aggregator with automated MEV profit sharing, innovative trading tools and custom RPC functionality. Works on major EVM chains. When you make a swap, and there are arbitrage opportunities available, the protocol executes the swap and closes the arbitrage opportunity in the same transaction allowing users to profit.

Mekatek is building an open blockspace market for the interchain future. This enables expression of a rich set of preferences and guarantees fee distribution to all parties in the value chain. All validators can offer blockspace to increase revenue for securing the infrastructure and profit sharing for delegators. Meanwhile, users can buy blockspace and express a rich set of preferences for how their transaction should be executed.

Manifold Finance enables and provides access to high-value transaction pools on EVM-compatible chains through its infrastructure, SecureRPC. It aggregates multiple endpoints and maintains direct access to disparate mining pools and validator nodes. The company's first solution, OpenMEV (formerly known as YCabal), is an aggregation strategy for scaling layer one, combining MEV and smart contract techniques to scale services like SushiSwap for end users.

Toby is a liquid staking reward protocol powered by MEV. Users will receive an equivalent amount of tSOL in return for their staked SOL. tSOL holders will automatically receive distributed Toby rewards.

Warlock is a MEV optimizes solution for where MEV and liquidation fees can get recaptured and passed on to the protocol and users in the form of lower fees.
