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 requires a one-time 25,000 $SATSBANK burn to enter and a continuous hold of at least 100,000 $SATSBANK. Every 5 minutes, 0.01% of your hold accrues as a BTCB reward. Claim unlimited times.
- ▸One-time burn of 25,000 $SATSBANK to enter
- ▸Continuous hold ≥ 100,000 $SATSBANK to keep accruing
- ▸Accrual pauses if hold drops below 100,000
- ▸Rewards paid in BTCB from the unified pool, unlimited claims
Module 3 · Investing
Investing is tiered staking. Stake 250k / 500k / 750k / 1M $SATSBANK to earn BTCB from the global pool every 5 minutes. The same tier can be topped up (principal accumulates); switching tier requires unstaking first. Stakes are locked for 5 minutes minimum.
- ▸Tier 1: 250,000 $SATSBANK · 0.02000% / 5 min
- ▸Tier 2: 500,000 $SATSBANK · 0.02100% / 5 min
- ▸Tier 3: 750,000 $SATSBANK · 0.02205% / 5 min
- ▸Tier 4: 1,000,000 $SATSBANK · 0.02315% / 5 min
- ▸Reward = current BTCB pool × tier rate
- ▸Same-tier top-up: principal accumulates, lock resets
Module 4 · Borrowing
Borrowing is coming soon. It will let users borrow BTCB against $SATSBANK collateral.
