The first Bitcoin L2 with full EVM compatibility & native Bitcoin support


We build open source software and contribute research to onboard one billion people to Bitcoin.

Our flagship project BOB (“Build on Bitcoin”) is a first-of-its-kind hybrid Layer-2 powered by Bitcoin and Ethereum. By combining the security, liquidity, userbase, and innovation of the two largest blockchain ecosystems, BOB closes the gap between Bitcoin as a vehicle for mass adoption and Ethereum as a hub for innovation. This is achieved through BOB’s rollup ecosystem that uses Bitcoin for settlement, storage, and security while enabling users to access all the on and off-ramps, dapps, stablecoins, NFTs, DeFi, etc. made possible by Ethereum’s EVM.

Our team is distributed globally across Europe (primary time zone), North America, and Asia. We live by the principles of decentralization and transparency. Operating as a 100% remote team, all our code is open source, and our products are community-owned, backed by top-tier research. Since 2015, we’ve been dedicated contributors to advancing Bitcoin and blockchain technology.

We are backed by some of the best VCs and angels in the space including Castle Island Ventures, Mechanism Capital, Bankless Ventures, CMS, and IOSG.
