The Aureus dollar

A dollar whose reserve works for you.

aUSD is minted one-for-one against USDG and stays redeemable one-for-one, always. Behind it, the treasury holds tokenized T-bills and lends into Aureus markets — and every cent that earns goes to holders who stake it as saUSD.

Mint & redeem

Deposit USDG, receive the same number of aUSD. Redeem any time; the treasury pays from its own buffer and unwinds its lending position in the same transaction when it must.

How it works

One dollar in, one dollar out — the yield is a choice.

Mint, one for one

Deposit USDG and receive the same number of aUSD. No price to check, no curve to cross — the treasury holds your dollar and owes it back.

The reserve goes to work

Treasury dollars spread across tokenized T-bills, the Aureus lending vault, and a liquid buffer that always stays home for redemptions.

Stake for the yield

aUSD itself never pays interest. Stake it into saUSD and everything the reserve earns is dripped to stakers over seven days, block by block.

The dollar

aUSD

A plain, transferable dollar. Hold it, trade it, post it, pool it — and redeem it for USDG at the treasury whenever you like. It never rebases and never pays interest, which is exactly what makes it usable everywhere.

Minted and redeemed 1:1 against USDG
Redemptions draw on a buffer that refills itself from the reserve
Not the vault share — auUSDG, the lending vault's token, is a different thing

The staked dollar

saUSD

Stake aUSD and hold saUSD, a vault share that only ever goes up in aUSD terms. T-bill income, lending interest, mint and redeem fees — the whole of the reserve's earnings vest to stakers smoothly over seven days.

Unstake any time — no lock, no cooldown
Rewards drip linearly, so there is no distribution to snipe

The reserve

Three places a treasury dollar can be.

Liquid USDG buffer

A floor of the reserve stays as plain USDG, so ordinary redemptions never wait on anything. Below the floor, the treasury refuses to invest.

Aureus lending vault

Part of the buffer earns borrower interest in the same vault lenders already use. Redemptions unwind it automatically when the liquid buffer runs short.

Tokenized T-bills

Short-dated US Treasury tokens on Robinhood Chain. Upside is counted only once it is paid; while any change is scheduled the treasury waits for the feed to reflect it.

Built like the markets

The same discipline, applied to a dollar.

✓Always redeemable at one dollarRedeeming burns aUSD against the treasury's own book — the exit does not depend on a pool having depth that day.
✓Conservative valuationThe reserve never counts a dividend before it is paid, and pauses everything valuation-dependent while a corporate action is scheduled.
✓Retained equity before payoutsYield is only distributed above a retained cushion sized to the risky side of the reserve.
✓Rate-limited operationsReserve rotation is bounded against the live price and rate-limited by a rolling daily allowance.
