How Banana Bank works
Buy bananas. Lock them up. Earn more bananas.
Banana Bank is a seven-day token-earning system built for apes. Your bananas enter a timed vault and generate liquid banana rewards that can be sold, reinvested, used for account upgrades, or contributed toward bank-wide boosts.
In Banana Bank, every banana you see means $BBANK tokens.

Inside the vault
Your bananas
Where your balance sits during a seven-day cycle.
The 7-day vault

Day 1–6Earn
Day 7Unlock
Vaulted $BBANK
Your original balance committed to the seven-day cycle and used as the main earning base.
Pending $BBANK
Apes can see how their $BBANK tokens grow in their wallet in real time.
Reinvested earning power
Temporary earning power created by reinvesting rewards. It resets when the vault opens.
Rewards stop accruing at the vault-end timestamp. Any rewards earned before that point remain claimable later under the contract's lazy-settlement model.
Level up
$BBANK daily rate
Level up your account and make the same deposit work harder.
Base rate
The base daily rate begins at 10%, drops by two percentage points each full week, and reaches a hard floor of 4% per day from week three onward.
Bonuses stack additively
Account tier, community level, contributor, burn and buyer bonuses are added to the base-rate multiplier rather than multiplied into one another.
Account tiers
| Tier | Earning multiplier | Upgrade cost | Sell tax |
|---|---|---|---|
| 1 | — | 7% | |
| 2 | 3% of locked $BBANK | 6% | |
| 3 | 3% of locked $BBANK | 5% | |
| 4 | 3% of locked $BBANK | 4% | |
| 5 | 3% of locked $BBANK | 3% | |
| 6 | 3% of locked $BBANK | 2% | |
| 7 | 3% of locked $BBANK | 1% |
Stronger together
Boost the bank
Chip in bananas and improve the system for every ape.
When transacting in Banana Bank, apes burn bananas into the Community Upgrade Fund. Each completed level permanently increases the earning bonus for every active account.
Community levels
| Level | Total contributed | Permanent bonus |
|---|---|---|
| 1 | +2% | |
| 2 | +4% | |
| 3 | +6% | |
| 4 | +8% | |
| 5 | +10% | |
| 6 | +12% | |
| 7 | +14% | |
| 8 | +16% | |
| 9 | +18% | |
| 10 | +20% |
Permanent bank upgrade
Every completed community level adds a permanent bonus for all active accounts — no expiry, no reset.
Ten levels to unlock
Contributions climb from +2% at level 1 to +20% at level 10, shared by every active account in the bank.

Exit paths
Wait for the vault to open
Your original bananas unlock automatically after seven days. Earnings stop at the end timestamp, your account tier resets, and you can begin another cycle.
Break the vault early
A 50% penalty applies to your vaulted balance plus accrued rewards. Half is returned, half is burned, and all account statistics reset.
Where bananas get burned
| Action | Effect |
|---|---|
| Account upgrade | 100% of upgrade cost burned |
| Reinvest | 100% burned → temporary earning power |
| Early exit | 50% of principal + rewards burned |
| Sell tax | 1–7% of every sell burned (if auto-LP is disabled) |
| Burn vaulted tokens on yield claim | 10% of the claimed tokens |
Burned bananas are gone for good. Bananas do not grow back.

Questions & answers
Straight answers, straight from the Banana Paper.
What exactly is Banana Bank?
A meme-themed, on-chain token-earning game built around a seven-day vault. You lock up your $BBANK bananas, banana rewards accrue every day, and you decide whether to sell them, reinvest them, upgrade your account or boost the whole bank. It is not a bank — no deposits, no interest, no insurance.
What does "one banana" actually mean?
Every banana you see means one $BBANK token. All rates and rewards are counted in tokens — never in dollars.
How do the daily rewards work?
Your earning base is your vaulted bananas plus any reinvested earning power. The base daily rate starts at 10% in launch week, drops by two percentage points each full week, and settles at a hard 4% floor from week three onward. Tier, community, contributor, burn and buyer bonuses are then added on top — additively, not multiplied.
Do the stocks I hold boost my rate?
Yes. Holding tokenized stocks on the RH chain adds a yield bonus on top of your base rate — hold at least one NVDA, TSLA or AAPL for +5% each, up to +15% total. Each stock is counted only once.
Can I take my bananas out before day 7?
Yes, but it costs you. Waiting is free: your original bananas unlock automatically after seven days, earnings stop at the end timestamp and your tier resets for the next cycle. Breaking the vault early triggers a 50% penalty on your vaulted balance plus accrued rewards — half is returned, half is burned, and all account statistics reset.
What happens when I sell?
Every sell is taxed between 1% and 7% depending on your account tier, and that tax auto-grows the liquidity pool. While your vault is active, selling rewards also removes locked principal equal to 10% of the total amount sold — and splitting a sale into smaller transactions does not avoid it.
Why would anyone burn bananas?
Burns power everything. Upgrading your account tier (up to a 210% earning multiplier) burns the upgrade cost, and community contributions build permanent bank-wide bonuses of up to +20% for every active account. On top of that, every 300,000 bananas burned — from any source — trigger +25% earnings for all apes for 3 hours.
Do I get anything for joining?
Every ape that joins Banana Bank receives a non-transferable NFT that displays account progress, earning statistics and tier information directly on-chain. You can view it in compatible NFT explorers and marketplaces.
Are these percentages guaranteed profit?
No. All percentages represent token-denominated emissions and contract bonuses. They are not guaranteed profits, bank interest, insured returns, or fiat-denominated yield — and the token price can rise or fall. Banana Bank is a meme-themed on-chain system, not a bank.
