01
Where the yield comes from
HoodBank is a non-custodial savings protocol on Robinhood Chain. You deposit $BANK, it
earns daily, and you can compound or withdraw whenever you like. Your keys stay yours:
funds move only through transactions you sign.
Now the part most projects avoid. There is no external yield source.
HoodBank does not lend, stake, farm or trade your $BANK. The contract makes exactly one
kind of external call, and it is a transfer of the $BANK token itself. Earnings are paid
out of the protocol's reserves, and those reserves are funded by deposits.
What that means for you. Returns depend on deposits continuing. If they stop, the
pool cannot keep paying. Every account is capped at 3× its deposit for life.
We tell you this because you can read the contract yourself in five minutes, and anyone
claiming an external yield is lying to you.
02
Your wallet and Robinhood Chain
You need a browser wallet: MetaMask, Rabby, Coinbase Wallet or OKX all work. On mobile,
open HoodBank inside your wallet app's browser, because wallet extensions cannot inject
into a normal mobile browser.
| Network | Robinhood Chain |
| Chain ID | 4663 |
| RPC | rpc.mainnet.chain.robinhood.com |
| Explorer | robinhoodchain.blockscout.com |
| Gas token | ETH |
You do not need to add the network by hand. Press Connect Wallet and HoodBank asks
your wallet to switch, adding the network if it is missing. If you decline, you stay
connected but every action stays locked until you switch.
You need a little ETH on Robinhood Chain. Gas is paid in ETH, not $BANK. A wallet
holding only $BANK cannot transact.
03
Getting $BANK
$BANK is the only token HoodBank accepts. Deposits of anything else are impossible: the
contract is bound to one token address, fixed when it was deployed and unchangeable
afterwards.
Buy $BANK on Robinhood Chain, then check the token address in your wallet matches the one
linked in our footer. Copy it from HoodBank rather than from a search result or a DM.
Fake tokens with identical names are the oldest trick there is.
04
Your first deposit
Depositing takes two transactions, and this surprises people. The first
is an approval: ERC20 tokens cannot be pulled by a contract unless you permit it.
The second is the deposit itself. HoodBank only asks for approval when your current
allowance is too low, so it is usually a one-time step.
| Minimum deposit | 1,000 BANK |
| Maximum per wallet | 10,000,000 BANK (1% of supply) |
| Deposit fee | 1% |
| Withdrawal fee | 5% |
The per-wallet cap is a total, not a per-transaction limit, and it exists so no single
wallet can corner the pool. If someone sent you a referral link, keep it in the address
bar when you deposit: the referrer is read from the URL at that moment and set once.
Where the fees go. Both fees go in full to a single treasury address, which
funds development, marketing and liquidity. It is set when the contract is deployed and
can never be changed, because the contract has no function to change it. You can
read it yourself on the explorer by calling TREASURY_ADDRESS. Its live balance is
shown on the home page, and that figure links straight to the address on the explorer, so
you never have to take our word for it. A community multisig is planned; until it exists,
treat the treasury as project-controlled.
05
The 10-day cycle
This is the lesson that decides whether you make money. Withdrawing carries a fee that
depends on one thing: how many days it has been since your last withdrawal.
090%
180%
270%
360%
450%
540%
630%
720%
810%
90%
1090%
The fee starts at 90% and drops 10 points a day. Day nine is the only day it
reaches 0%. On day ten it resets to 90% and the whole cycle runs again. There is
exactly one free day in every ten.
Miss day nine and you pay 90%. On 1,000 BANK of earnings that is the difference
between taking home 950 and taking home 95. The counter resets the moment you
withdraw, so a withdrawal on day nine puts you back at day zero.
The penalty is not shared out among other depositors. People often assume it is
recycled into the pool. It is not: the penalty is transferred to the treasury, in full,
the moment you withdraw. Worth knowing before you decide the timing does not matter.
You do not have to track this yourself. The Withdraw button always shows your live
rate, and on your free day it turns lime and counts down the hours you have left.
06
Why compounding daily matters
Compounding moves your earnings into your principal, so tomorrow's earnings are calculated
on a larger balance. It costs one transaction and nothing else. There is no fee to
compound.
| 10,000 BANK at 3.5%, over one 9-day cycle | Earned |
|---|
| Never compounding | 3,150 BANK |
| Compounding daily | 3,629 BANK |
| Difference | +15% |
Fifteen percent, for nine button presses. Over many cycles the gap widens, which is the
whole reason the fee schedule pushes you to hold rather than withdraw.
There is a floor. You need at least 30 BANK of unclaimed earnings to
compound. At the 1,000 BANK minimum deposit you clear that in about 21 hours, so daily
compounding works even at the smallest size. The Compound button stays disabled until you
are eligible and tells you how long is left.
07
Referrals and rate tiers
Share your referral link and you earn 5% of your invitee's first deposit.
It also does something more valuable: eligible referrals raise your own daily rate, from
3.5% up to 6.5%.
| Eligible referrals | Your daily rate |
|---|
| 0 – 9 | 3.5% |
| 10 – 24 | 4.0% |
| 25 – 49 | 4.5% |
| 50 – 99 | 5.0% |
| 100 – 149 | 5.5% |
| 150 – 249 | 6.0% |
| 250+ | 6.5% |
"Eligible" has a threshold. A referral only counts toward your tier once that wallet
has deposited at least 15,000 BANK in total. It stops people farming tiers with
hundreds of dust wallets.
Two limits worth knowing before you recruit.
The 5% pays once per wallet, on its first deposit only. If someone you referred
deposits ten more times after that, you earn nothing further from them, though they
still count toward your rate tier. And the bonus is credited to your principal, which is
capped at 10,000,000 BANK: once you are at the cap, further referrals pay you no
bonus at all, and only the tier upgrade still helps.
08
Risks, stated plainly
- Earnings are capped at 3× your deposit. Once your lifetime payout reaches
three times what you put in, the account stops paying. It is a hard ceiling in the code.
- The pool depends on deposits. As lesson one explains, there is no external
yield. If deposits dry up, the reserves cannot cover withdrawals.
- The early withdrawal fee is severe. Up to 90%, and it resets every ten days.
It is not a warning label, it is the mechanic.
- The contract cannot be changed. Rates, caps, fees and the treasury address are
fixed at deployment. That protects you from rug-pull edits: nobody can redirect the
treasury, not even us. It equally means nothing can be fixed if it turns out wrong.
- The treasury is project-controlled for now. Every fee and every early
withdrawal penalty goes there. A multisig is planned, but until it is live you are
trusting the project with those funds. Watch the address on the explorer.
- $BANK can fall. Every figure in the app is denominated in BANK, never dollars.
A rising balance can still be worth less than you paid.
This is not financial advice, and HoodBank is an experiment. Never deposit more than you
can afford to lose completely.
That is the whole course. The Vault is where you put it to work.
