BOB is a Hybrid Layer-2 that inherits its security directly from Bitcoin while enabling smart-contract functionality and cross-chain interoperability. It uses optimistic verification powered by BitVM2 so state transitions and withdrawals can be challenged on Bitcoin, and it implements trust-minimized bridges to Bitcoin and Ethereum that rely on a 1-of-n “existential honesty” model rather than trusted multisig operators.
By anchoring security to Bitcoin, BOB aims to unlock DeFi for BTC without changing Bitcoin’s base protocol: users can deposit BTC (and assets from other chains) into BOB to trade, lend, and build applications against native BTC liquidity. This approach reduces the need to wrap BTC on many separate chains, concentrates liquidity around Bitcoin, and routes fees back to support Bitcoin’s long-term security budget.
BOB’s rollout is staged: it begins as an Ethereum L2 to leverage existing tooling and network effects, adds Bitcoin “soft” finality to accelerate withdrawals, and ultimately transitions to full Bitcoin security through BitVM optimistic rollups when economically feasible. The long-term vision is for BOB to make Bitcoin the interoperable, trust-minimized hub of multi-chain DeFi, offering secure bridges to most smart-contract chains and an alternative to centralized exchanges.

What is the allocation for Build on Bitcoin(BOB)?
At launch, the initial circulating supply of unlocked tokens will be 22.20%. Approximately 0.51 billion tokens (5.1%) will be in community hands through initial claims and the community sale. Roughly 1.46 billion tokens (14.6%) allocated to Ecosystem & Community and 0.25 billion tokens (2.5%) allocated to the BOB Foundation will also be unlocked at launch.
Tokens allocated to Core Contributors and Early Backers are locked at launch and subject to pre-defined vesting and lockup schedules spanning over 2-3 years to ensure long term alignment with the success of BOB. In total 77.8% of the total BOB token supply will be locked on day 1. Tokens allocated to Foundation and Ecosystem & Community are also subject to vesting and unlock over 48 months. The full 10 billion supply will be unlocked 48 months after the BOB token launch.

What is the supply schedule for Build on Bitcoin(BOB)?
Approximately 44.76% of BOB tokens are reserved for Ecosystem and Community. Roughly one third of these tokens (14.6% of total supply) will be unlocked at TGE with the remainder linearly unlocked over 48 months. This is to ensure the BOB DAO can utilize the treasury for growth initiatives early on while at the same time ensuring long-term oriented planning. These resources will be stewarded by the BOB Foundation together with the BOB DAO via onchain governance.
This allocation will be used to support the growth of the BOB ecosystem and community through ongoing community, builder and DeFi initiatives, also including staking rewards. A minority (5%) has been pre-allocated towards early DeFi, liquidity and ecosystem growth strategy. The remaining 39.76% will be overseen by the BOB Foundation and BOB DAO for many years to come.
