The fee lever, and what the fees go on to fund.
Holding HUSDB lowers your withdrawal fee today. Everything past that — staking, governance, a share of USDG reserve yield — is paid for by the same fee flow, through buybacks and permanent burns.

One job, shipped. The rest is described, not promised.
Withdrawal fees are calculated from your HUSDB balance. That is the whole of what the token does right now, and we would rather say so than dress a roadmap as a feature list.
We publish the shape, not a table that would go stale.
The discount schedule is dynamic and served by the API. Printing numbers here would turn a parameter into a promise, and the first time the schedule moved we would have published a falsehood on a site whose whole method is checkability.
What is fixed: the fee never rises with your balance, the discount applies to withdrawals and not to transfers, and the exact figure is shown before you confirm.
The curve falls and never rises. Where the steps sit, and how far the discount goes, is set by the live schedule — which is why this chart has no numbers on it.
Withdrawals, and the routing that makes privacy work
The protocol earns on the two actions that cost it something: paying out on-chain from the pooled reserve, and running a full-privacy deposit through the pipeline. Everything that costs nothing — an internal transfer, creating a link, creating a request — is free.
- ETH withdrawal — 1.5%, discounted by HUSDB balance
- USDG withdrawal — shown at confirmation
- Full-privacy deposit — a small routing fee during mixing
- Transfers, pay links and requests — free to create and to settle internally
Collection, buyback, burn — then holders
Collected fees fund buybacks on Robinhood Chain DEXs, and the bought supply is burned permanently. What the flywheel supports after that is staking rewards, governance, and a share of the USDG reserve yield the Global Dollar Network pays ecosystem partners.
- FeeCollector accrues protocol fees
- Buyback executed on Robinhood Chain DEXs
- Permanent burn — supply does not come back
- Staking, governance and yield share are next, not now
Four things the token will do that it does not do yet.
Listed here rather than mixed into the live section, because a reader should be able to tell the two apart without reading carefully.
Staking
Stake HUSDB for a share of protocol fees. Not live.
NextGovernance
Vote on fees and on privacy parameters — split counts, staggering, denominations. Not live.
NextPrivacy-pool LP
Provide depth to the pool and earn from it. Not live.
NextUSDG yield share
Because settlement is in USDG, in-protocol holders can share the reserve yield paid to Global Dollar Network partners. Not live.
NextTwo roles, one token.
One of them changes what you pay today. The other is how the pool gets deeper — and its reward is on the roadmap, not in your wallet.
Holder
Hold HUSDB in your own wallet and your withdrawal fee is computed at a better tier. Nothing to lock, nothing to claim, no second contract to approve. The app reads your balance when you open the withdraw screen and shows the tier, the discount it applies and the next threshold before you sign.
Privacy-pool LP
Providing depth to the privacy pool is a named holder role. Depth is not a side effect of the mechanism, it is the mechanism: the more that sits in the pooled reserve, the less any single deposit stands out inside it. Rewards for LPs are part of the fee flywheel and are not live.
The checkable parts.
Nothing here is a projection. Everything on this table is either on-chain or in the docs.

HUSDB is a protocol token, not an investment product. Nothing on this page is financial advice, and none of it is a projection of value.
The token is the smallest part of what makes this work.
The protocol is the pool, the routing, the relayer and the ledger. Read what it does, and read the account of where it stops.
