What Is Zephyr Protocol?
Zephyr Protocol is a crypto-backed, over-collateralized, private, decentralized Stablecoin protocol; inspired by the Djed Protocol on a native Monero based chain, inheriting all privacy features for all assets. Launched on 29/05/2023.
Zephyr Protocol uses a three asset model: ZEPH, ZSD and ZRS for powering the Stablecoin Protocol:
ZEPH is the “Base coin” which is used as the collateralization in the stablecoin protocol as well as minting ZSD and ZRS by adding the equivalent ZEPH value to the reserve.
ZSD - Zephyr Stable Dollar - is a Private Stablecoin, backed by at least 400% equivalent value in ZEPH at time of minting.
ZRS - Zephyr Reserve Shares - is the “Reserve coin” which represents a share of the excess equity of the reserve. Users mint ZRS in return for adding ZEPH to the reserve. ZRS coins act as shares of the reserves excess equity and the value of ZRS is formulaically calculated in protocol. Simplified, the value of ZRS is correlated to the reserve ratio, dropping when reserves are low and increasing when reserves are high. To avoid dilution for the ZRS holders, there is a maximum reserve ratio of 800% at which time no more ZRS can be minted.
Reserve Provider Incentives
Leveraged Position: as ZEPH's value increases the amount of ZEPH each ZRS is redeemable for increases. Collect Fees for Actions: When users mint or redeem ZSD and redeem ZRS they incur a fee which is added to the reserve. Spot and MA Price Deviation: The value returned for performed actions is calculated by the worst price between the Spot and MA. This value discrepancy is added to the reserve. Block Reward: A portion of the block reward (20% from v1 and 30% from v2) is added to the reserve directly which serves as a pseudo-staking reward mechanism to bolster the reserve.
ZSD Yield
Introduced in v2.0.0, the ZSD Yield Mechanism allocates 5% of the block reward to mint new ZSD, which is then added to the Yield Reserve. Users who stake ZSD receive Zephyr Yield Shares (ZYS), representing shares in this growing reserve. As more ZSD is added through the yield process, the value of ZYS appreciates.
