The Problem
Decentralised stablecoins are dominated by USD-pegged designs that rely on external oracles and team-controlled admin keys, leaving non-USD users without a credibly neutral, locally denominated stablecoin.
The Solution
Frankencoin issues ZCHF, an oracle-free, over-collateralised CHF stablecoin where prices are discovered on-chain via multi-day challenge auctions, equity-token (FPS) holders absorb residual loss, and all core contracts are immutable.
Why it Matters
The only material decentralised Swiss-franc stablecoin, the only major CDP design with no external oracle dependency, and one of the very few stablecoins with truly immutable core contracts and no pause/blacklist functions anywhere in the system.
