Prisma Finance is an Ethereum CDP (collateralized debt position) protocol that issues the mkUSD stablecoin exclusively against liquid staking tokens (wstETH, cbETH, rETH, sfrxETH) — deep within the Curve ecosystem — using vote-escrow tokenomics to direct mkUSD liquidity incentives and a debt interest model calibrated to LSD yield.
Overview
Launched in 2023, Prisma Finance targeted the intersection of two dominant DeFi themes: the liquid staking derivatives (LSD) boom post-Ethereum Merge and Curve Finance’s deep stablecoin liquidity. By accepting only Ethereum staking derivatives as collateral and integrating tightly with Curve, Convex, and related vote-escrow protocols, Prisma created an LSD-specific borrowing layer where users could leverage their staked ETH yield without selling their staking position. The PRISMA token governs the protocol with a vote-escrow model replicating Curve’s mechanics.
mkUSD Stablecoin
mkUSD is Prisma’s CDP-issued stablecoin:
- Overcollateralized — users mint mkUSD by depositing LSD collateral at minimum collateral ratios (typically 110–120% depending on collateral)
- Hard peg mechanisms — redemption floor (1 mkUSD always redeemable for $1 of collateral at face value) prevents mkUSD from trading below $1; ceiling maintained by PRISMA governance and Curve pool depth
- No interest rate — mkUSD carrying cost is the one-time minting fee (similar to Liquity’s one-time fee model, not ongoing interest)
- Curve integration — mkUSD is designed to live in Curve stable pools, with PRISMA emissions directed by vePRISMA voters toward mkUSD/crvUSD or mkUSD/FRAX pools
Supported Collateral
Prisma accepts Ethereum LSD tokens only:
- wstETH — Lido wrapped staked ETH (primary collateral)
- cbETH — Coinbase staked ETH
- rETH — Rocket Pool staked ETH
- sfrxETH — Staked FRAX ETH (frxETH staking version)
All collateral generates underlying staking yield for the user while serving as CDP backing, meaning borrowers effectively receive a “yield-bearing loan” — the staking APR partially offsets the mkUSD minting fee.
PRISMA Token and vePRISMA
Prisma uses a Curve-inspired governance model:
PRISMA:
- Governance and emissions token
- Locked for up to 52 weeks to receive vePRISMA
- veLockers direct mkUSD liquidity incentives to Curve pools via gauge-style voting
vePRISMA:
- Weighted governance power decaying with time remaining on lock
- Gauge voting rights: direct PRISMA emissions to mkUSD Curve pools
- Bribe market: protocols and Curve wars participants pay vePRISMA holders to vote for specific pools
Curve Wars Integration
Prisma positioned itself within the “Curve Wars” ecosystem:
- mkUSD needs Curve pool depth for peg stability and liquidity
- PRISMA emissions direct Curve gauge votes toward mkUSD pools
- Convex Finance, Stake DAO, and similar Curve aggregators can boost mkUSD pool APYs by directing their veCRV votes
- vePRISMA bribe market enables direct incentive payments to voters
