sdUSD — the staked Denar dollar.
Why unstaked dUSD earns nothing
This is the system’s engine, so it is worth saying without spin: the reserve earns on every dUSD in circulation, but pays only the staked ones. A dUSD sitting in a wallet, a liquidity pool, or a collateral position contributes its share of reserve income to the stakers who opted in. The more dUSD lives its life as a dollar, the higher the staking rate sits above the reserve’s raw yield. That is the same architecture used by the largest reserve-backed dollars in DeFi — a base token that stays boring, and a staking wrapper that concentrates the yield.The seven-day drip
Harvested rewards are not credited at once. Each distribution is transferred into the vault and vests linearly over seven days; a new distribution folds any still-unvested remainder into a fresh seven-day round, so the share price is a smooth, continuous line rather than a staircase. The consequences are exactly the ones you would want:- No sandwich. Staking one block before a harvest captures nothing instant — you collect only your pro-rata slice of the drip for as long as you stay.
- No cliff on exit. Unstaking mid-drip pays the vested share price at that moment; nothing you have already accrued can be taken back.
- Multiple payers, no coordination. The T-bill harvest and the lending harvest land whenever they are ready; the vault folds them together.
