Protocol Overview
SATOSHI BANK (Satoshi Bank) is a decentralized banking protocol on BNB Chain trading as SATSBANK / BTCB. All rewards flow from one unified BTCB pool, funded 100% by token tax arriving as BTCB or by anyone calling fundRewardPool().
- ▸Trading pair: SATSBANK / BTCB
- ▸Single BTCB reward pool shared by every module
- ▸Tax lands as BTCB and routes 100% into the pool — no split
- ▸BTCB = Binance-Peg BTC (0x7130d2A12B9BCbFAe4f2634d864A1Ee1Ce3Ead9c)
- ▸Cycle reference: 5 minutes
- ▸Every wallet can participate without limit in Lend / Supporting / Investing
Module 1 · Lend
Lend is the BTCB deposit path. Approve BTCB, deposit, wait the 5-minute cycle, then claim back principal plus a 0.05% BTCB reward. Top up unlimited times.
- ▸One-time BTCB approval to the vault before the first deposit
- ▸No limit — every new deposit accumulates principal and resets the 5-minute cycle
- ▸Reward = 0.05% × deposit
- ▸Claim BTCB principal + reward after 5 minutes
- ▸Principal is accounted separately; the reward is reserved from the unified pool
Module 2 · Satoshi Supporting
Satoshi Supporting has no minimum hold. Burn any amount of $SATSBANK to gain burn weight; every 10 minutes the module distributes 0.001% of the BTCB reward pool pro-rata across all burn weight. Burn as often as you like — more burn, bigger share.
- ▸Burn any amount of $SATSBANK — no maximum
- ▸No minimum hold requirement
- ▸0.001% of the pool every 10 minutes, pro-rata by burn weight
- ▸Rewards paid in BTCB from the unified pool, unlimited claims
Module 3 · Investing
Investing is a single tier. One stake unit is 250,000 $SATSBANK and earns 0.02% of the global BTCB reward pool every 5 minutes per unit. Stack as many units as you like — principal accumulates. Stakes are locked for 5 minutes minimum.
- ▸Single tier: 250,000 $SATSBANK per unit
- ▸0.02000% of the pool / 5 min per unit
- ▸Reward = current BTCB pool × 0.02% × units staked
- ▸Unlimited stacking: principal accumulates, lock resets
Module 4 · Borrowing
Borrowing is coming soon. It will let users borrow BTCB against $SATSBANK collateral.

- ▸Smart contracts may contain unknown risks
- ▸Confirmed transactions cannot be reversed
- ▸Reward outcomes depend on the BTCB pool balance
- ▸Only use funds you can afford to lose
