Stability Mechanism


We will use a protocol reserve as our primary stability mechanism.

  • DSU can always be minted from the reserve for 1 USDC
  • DSU can always be burned in the reserve for RR*USDC, where RR is the current reserve ratio capped at 1.00

Reserve Ratio

The reserve ratio is the ratio of the USDC-denominated value of the reserve over the currently issued DSU. During normal operation this ratio will equal or exceed 100%.

In extenuating circumstances like an exploit or a bug the ratio may drop below 100% . In this case the redemption price is pro-rated such that redeeming earlier does not guarantee an optimal exit result. This prevents bank runs in times of uncertainty to allow the protocol time to recover if possible.

ESS as a backstop

In addition to acting as a seignorage share and governance token, ESS can backstop the reserve for the protocol.‌

At any time, governance may vote to mint and sell ESS to raise RR if it drops below its expected operating value.

Future Mechanics

The initial launch of the protocol has no ancillary stability mechanisms which might reduce the reserve ratio below 1. However in the future mechanisms may be suggested, modelled and proposed to the DAO.

Safely Experimenting

To enable a safe experimentation environment once we’ve bootstrapped, governance can artificially lower the redemption price using an EXIT_TAX to create a non-zero hard price range. This enables safe efficacy testing for various ancillary stability mechanisms while the system is still over-collateralized and can easily rollback.
