Three project assets. Different responsibilities.

Project tokens

BBKFI contract behavior

The verified BBKFI source is an ERC-20-compatible token with delegation checkpoints. Holders can delegate votes directly or by EIP-712 signature, and historical votes can be queried with getPriorVotes.

Its mint(address,uint256) function is protected by onlyOwner. On-chain, the token’s owner is the MasterChef, so new BBKFI is only minted through MasterChef pool accounting rather than an unrestricted public function. The MasterChef source has no function that transfers BBKFI ownership onward.

The emission formula

poolReward = elapsedBlocks × bbkfiPerBlock × pool.allocPoint / totalAllocPoint
userPending = user.amount × pool.accBBKFIPerShare / 1e12 − user.rewardDebt

That formula describes the code. It does not make a static APR promise. APR also depends on token prices, total stake, pool weight, deposit fee, block cadence and the moment the pool was last updated.

A pool with zero stake mints nothing when it is updated, so allocation points held by an empty pool reduce the effective emission of the whole MasterChef. Read bbkfiPerBlock, totalAllocPoint and each pool’s allocPoint and stake together before estimating daily issuance.

SmartChef rewards

SmartChef pools do not use the shared MasterChef emission. Each discovered SmartChef address has its own:

• staked token and reward token;
• rewardPerBlock;
• start and end block;
• optional per-user limit;
• pre-funded reward balance.

The owner can stop rewards early, and a pool stops accruing after its end block. The Earn screen reads these fields before showing an active, upcoming, or ended state.

Liquidity provider fees

Trading fees are not emissions. They come from swappers and accrue to liquidity providers inside the pools:

• BitBlocks V2: a 0.25% fee per hop stays in the pair. Because the factory’s feeTo is set, the protocol mints LP tokens worth 8/25 of fee growth, so liquidity providers keep about 0.17%.
• BitBlocks V3: the fee tier of the pool (0.01%, 0.05%, 0.3% or 1%) is credited to in-range positions. A protocol share of 5% is set by default on new pools and can be changed per pool from 0% to 40% by the factory owner.
