Minting & Redemption
SILK minting methods
Minting a stablecoin is the act of issuing a token that ultimately takes the form of a liability that the protocol must answer for at a later time via redemption or sale of the stablecoin for a corresponding amount of underlying promised value. The incentive for a protocol to issue a liability in the form of stablecoin to a user is on the basis of revenue received from the user for the service provided. With SILK, users repay Shade Protocol for the service provided primarily via interest payments as well as liquidation profit-sharing. SILK uses a hybrid model utilizing the following stability and minting mechanisms:
A minting model that follows the tried and true collateralized lending of MakerDAO. An overcollateralized amount of volatile assets back a finite set of stable assets via a process of interest payment incentives and liquidations.
A redemption mechanism whereby SILK is redeemed against tranches of at risk lending positions.
A mechanism whereby the protocol can repurchase or issue SILK at a discount or premium to help grow the treasury as well as maintain stability of the SILK peg.
With many different stability mechanisms available for Shade Protocol, there becomes a need to address the collateralization philosophy of the protocol with respect to what stability and minting mechanism are most heavily relied on over the lifespan of the protocol.
The following are a set of stability principles for Shade Protocol:
- Stability > Growth
- SILK > SHD
- Commerce creates stability
- Build reserves for unforeseen future bad debt
- Diversify where SILK is used in DeFi
- Openly plan for the failure of SILK
- Openly plan prevention steps in event of peg failure
- Natural pessimism towards bridging solutions
- Natural pessimism about quality of assets backing SILK
- Recommended that collateralization ratio of SILK targets 90 - 150%
