Welcome to BOB

This is a guide to get you started with building on BOB. BOB is leveraging an OP Stack-based rollup and is EVM compatible. This means that you can use the same tools and libraries that you are used to from Ethereum. In addition, BOB provides several useful tools to interact with Bitcoin.

Our docs are open source and we are happy to receive both feedback and contributions.
