As demand for USDs rises, more SPA will be burned. In the event that future governance votes in favor of allocation of protocol fees to SPA stakers, more fees will be distributed to SPA token holders.
SPA token's scarcity can eventually increase cash flow for SPA holders and stabilize SPA staking returns. Such mechanisms will further decentralize the USDs protocol and make USDs truly permission-less, censorship-resistant, and scalable.
While trust-minimized and scalable, most algorithmic stablecoins struggle to grow with periods of volatility or reliance on self-infused collateral. USDs resolves these problems by borrowing insights from the best of both worlds: crypto collateralized stablecoins and algorithmic stablecoins.
