USDu: the dollar that earns only after it changes clothes

Unitas separates its promise into two tokens. USDu tries to remain a dollar while sUSDu absorbs the earnings of hedged trading strategies. The separation is elegant; the machinery behind it still depends on allowlists, custodians, short-perpetual venues and administrators who can stop or restrict the route.

Two tokens divide one promise

USDu is the unit meant to move around one dollar. It does not rebase and its holder does not receive strategy income merely by waiting.

A user who wants the income deposits USDu and receives sUSDu. The share price rises only when a rewarder transfers earned USDu into the staking pool.

That accounting boundary matters: market price can move independently from the staking exchange rate, so USDu peg performance and sUSDu strategy performance answer different questions.

The mint has a front door and a service entrance

Most users swap into USDu on a market. Direct minting and collateral redemption are reserved for approved institutions, market makers and protocol accounts.

On BSC every order carries an expiry, nonce, signer, beneficiary and collateral route. Per-block caps slow throughput, while administrators decide assets, custodians, signers, limits and operational roles.

Delta-neutral is a verb, not a property

Collateral such as JLP and major assets creates a long position. Unitas opens short perpetuals and rebalances them around hourly so price moves offset each other.

The hedge can drift between adjustments; funding can reverse; an exchange, custodian or bot can fail. “Market neutral” describes continuous work, not a vault immune to liquidation or loss.

Some collateral leaves the chain without entering an exchange

Documents describe multisig vaults plus off-exchange settlement through Copper, Ceffu and trading venues. Custodians mirror balances so positions can trade while assets remain in segregated cold storage.

This reduces direct exchange custody but adds legal and operational counterparties. A dashboard is evidence only when every vault, mirror, hedge and issued token reconciles at the same timestamp.

Seven days from a savings share to a USDu withdrawal

Unstaking burns sUSDu and moves the corresponding USDu into a withdrawal contract. The documented cooldown is seven days, during which that amount no longer earns strategy rewards. The withdrawal returns USDu tokens, not cash.

An urgent holder can sell sUSDu if a market exists, accepting price impact. Historical APR of 8-15% in stable conditions is an observation, not a floor.

The emergency brake reaches farther than the slogan

The BSC token owner can replace the single minter and cannot renounce ownership. Minting contracts have gatekeeper and admin roles; staking includes blacklist and balance-redistribution powers.

The terms first say Unipay cannot unilaterally alter balances, then reserve power to freeze, burn or restrict tokens without notice for suspected breaches. Both statements belong in the control story.

Redemption is a right with gates and disclaimers

The terms describe burning USDu for a pro-rata share of collateral, subject to protocol rules and throttles. Public users, however, are told direct redemption is allowlisted, so secondary liquidity may be their practical exit.

Unipay gives no guarantee of the one-dollar peg or positive yield, excludes deposit insurance and limits liability. USDu is a managed claim path through code and contracts, not cash in a protected bank account.

What is USDu?

USDu is a dollar-referenced stablecoin operated by Unipay through the Unitas protocol on Solana and BNB Smart Chain. Yield belongs to the separate sUSDu staking share, not to idle USDu.

What problem does USDu solve?

A dollar token can be liquid but unproductive, while a yield token can hide market and custody risk. Unitas tries to keep the payment unit near one dollar and place strategy income in a separate share.

How does USDu work?

Allowlisted operators accept approved collateral, route it to vaults or custodians and mint USDu against signed orders. Spot positions are paired with perpetual shorts. Stakers exchange USDu for sUSDu; reward deposits raise each share’s USDu value.
