BOB, which stands for “Build on Bitcoin,” has now become a vital part of the Superchain ecosystem, which is expanding with Optimism’s OP Stack. Serving as a hybrid layer-two (L2) solution, BOB leverages the unique strengths of both Bitcoin and Ethereum by combining Bitcoin’s security features with Ethereum’s flexible framework. This innovative fusion addresses the limitations of Bitcoin in smart contracts and interoperability, creating a reliable bridge to Ethereum Virtual Machine (EVM) decentralized finance (defi) tools for seamless access. The primary goal of BOB is to enrich the Superchain experience by offering features like one-click BTC staking and user-friendly onboarding processes, which make BTC defi more efficient for both users and developers. BOB seamlessly integrates with BTC staking layers like Babylon and liquid staking tokens (LSTs) such as Solv and Bedrock. At present, BOB boasts support for 40 active projects, with an additional 60 projects in the development pipeline, and it currently secures over $100 million in total value locked (TVL).
