XUSD Shares (XUS)
The XUSD Share token (XUS) is the non-stable, value-accrual token in the protocol. It is meant to be volatile and hold rights to governance and all excess collateral of the system. It is important to note that we take a highly governance-minimized approach to designing trustless money in the same ethos as Bitcoin. We eschew DAO-like active management such as MakerDAO. The less parameters for a community to be able to actively manage, the less there is to disagree on. The only parameters that are up for governance through XUS is adding/adjusting collateral pools, adjusting minting/redemption fees, and refresh rate of the collateral ratio. No other actions such as active management of collateral or addition of human-modifiable parameters are possible other than a hardfork that would require voluntarily moving to a new implementation entirely. The XUS token has the potential of upside and downside of the system, where the delta changes in value are always stabilized away from the XUSD token itself. XUS supply is initially set to 500k tokens at genesis, but the amount in circulation will likely be deflationary as XUSD is minted at higher algorithmic ratios. The design of the protocol is such that XUS would be largely deflationary in supply as long as XUSD demand grows.
The XUS token’s market capitalization should be calculated as the future expected net value creation from seigniorage of XUSD tokens in perpetuity, the cash flow from minting and redemption fees, and utilization of unused collateral. Additionally, as the market cap of XUS increases, so does the system’s ability to keep XUSD stable. Thus, the priority in the design is to accrue maximal value to the XUS token while maintaining XUSD as a stable currency. As Robert Sam’s described in the original Seigniorage Shares whitepaper: “Share tokens are like the asset side of a central bank’s balance sheet. The market capitalisation of shares at any point in time fixes the upper limit on how much the coin supply can be reduced.” Likewise, the XUSD protocol takes inspiration from Sams’ proposal as XUSD is a hybrid (fractional) seigniorage shares model.
