Zephyr Protocol is an Over-Collateralized Private Stablecoin Protocol inspired by Djed Protocol on a native Monero based chain, inheriting all privacy features for all assets. Zephyr Protocol uses a three asset model: ZEPH, ZephUSD and ZephRSV.
ZEPH is the Base coin which is used for the collateralization in the stablecoin protocol as well as minting ZephUSD and ZephRSV by adding the equivalent ZEPH value to the reserve.
ZephUSD is a Private Stablecoin, backed by at least 400% equivalent value in ZEPH at time of minting. ZephRSV is the Reserve coin. Users are rewarded with ZephRSV when they add ZEPH to the reserve. ZephRSV coins act as shares of the reserves equity and the value of ZephRSV is formulaically calculated in protocol. Simplified, the value of ZephRSV is correlated to the reserve ratio, dropping when reserves are low and increasing when reserves are high. To avoid dilution for the ZephRSV holders, there is a maximum reserve ratio of 800% at which time no more ZephRSV can be minted.
