[PIP-47] Operation Rainbow Pegger

Operation Rainbow Pegger

Proposal

This proposal aims to address the upward depeg of Prisma stablecoins by introducing two Peg Stability Modules (PSMs), and a simple UI for interactions.

These modules are designed to stabilize prices, improve liquidity, and provide a more cost effective experience to borrowers as they close out their positions on Prisma.

Background + Motivation

If the recently proposed PIP-46 passes, the Prisma protocol will be fully shut down. At the time of writing, both mkUSD and ULTRA are both meaningfully above their $1 peg which creates significant challenges for active borrowers as they must contend with:

  • Rapidly increasing interest rates, pressuring quick action
  • Dramatically insufficient mkUSD and ULTRA liquidity available to fully close all open positions

This liquidity shortage will only become even more acute with time as we can expect:

  • Cessation of emissions, reducing incentives for liquidity provision.
  • Speculative hoarding of mkUSD and ULTRA, creating artificial scarcity

Without a solution to address the liquidity shortage, a subsequent depeg is expected to occur as borrowers are forced to buy these tokens at higher and higher prices.

Specification

  1. Conditionally allocate $5k (roughly 125k PRISMA at time of writing) from the Fee Receiver as a grant to pay for UI development.
  2. Deploy Two New Peg Stability Modules:
    • Prisma PSM: Mints mkUSD.
    • PrismaLRT PSM: Mints ULTRA.
  3. Enable Borrower Repayments via PSMs:
    • Allow users with open loans to repay mkUSD or ULTRA via the PSM in exchange for crvUSD at a 1:1 rate.
  4. Enable crvUSD redemptions for mkUSD and ULTRA:
    • Allow users to purchase crvUSD from the respective PSM using mkUSD or ULTRA at a 1:1 rate

modified the proposal to denominate the UI development grant in USD rather than PRISMA
