What is BOB (Build on Bitcoin)?

BOB (Build on Bitcoin) is a cryptocurrency project describing a “Bank of Bitcoin” platform intended to support swapping, saving, earning, and borrowing using Bitcoin rails. It is presented as a hybrid approach combining Bitcoin security with Ethereum-like versatility, and as a unified BTCFi gateway that enables deposit and DeFi interaction across chains. The description also states that BTC on BOB is intended to function as BTC, and references BitVM as part of that design.

BOB is described as using a hybrid chain model that combines zero-knowledge proofs and Bitcoin finality for transaction security. It is said to provide native rollup bridges to Ethereum and Bitcoin. The project further describes a multichain BTC gateway using “Bitcoin intents” and LayerZero, and a vault layer that packages tokenized BTC yield into “1-click strategies,” with security attributed to institutional curators and custodians. The description includes claims about co-authoring the BitVM2 paper and founding the bitvm/acc institutional alliance, but no founding year, founder names, supply cap, or governance model are provided.
