Use this page to understand DAI and why Maker mattered. Use Sky Protocol for USDS, sUSDS and current governance (SKY). Skip both if you wanted a fiat-backed coin. A rebrand does not delete smart-contract or collateral risk, and 2019 lore is not a live rate.

Collateral crashes, liquidation, and governance parameter risk — the same family as any CDP. Black Thursday 2020 is the historical lesson. Current parameters live on Sky’s docs, not in a frozen paragraph here. A rebrand does not delete those failure modes.
For live dollars and the savings rate, use sky.money and our Sky Protocol article. This Maker page is the history and the fork in the road. Do not mint from a 2018 mental model without reading Sky’s current parameters. USDC remains the issuer-dollar alternative.
