We're a small team of 22 people, half scientists, half engineers, working with blockchain-first companies only, from L1 to L2 and DeFi protocols, among others Axelar, Espresso Systems, Mysten Labs, Celestia, Babylon, Flashbots, and Flare Networks among our customers, and multiple research grants from Ethereum Foundation. Beyond consulting, our engineering team is building core and foundational open source libraries and tooling to power the blockchain systems of tomorrow for the betterment of the community, focusing on Ethereum, Cosmos, and Bitcoin; and our research team is openly publishing papers in A* peer-reviewed scientific conferences and journals on all the foundational topics in the space, with the goal of getting performant protocols proven secure, cited, appreciated, implemented and deployed.
