Deep Dive
1. Evolution from MakerDAO
Sky Protocol is the product of a major rebrand and overhaul of MakerDAO, a foundational DeFi lending platform launched in 2015. This transition, dubbed "Endgame," was completed in August 2024 (ChangeHero). The goal was to move beyond a single-protocol model to a scalable, community-driven ecosystem. The legacy MKR governance token was upgraded to SKY at a 1:24,000 ratio to make governance more accessible to a broader set of holders.
2. USDS Stablecoin & Yield Engine
The protocol's primary function is to issue and manage USDS, a decentralized, over-collateralized stablecoin pegged to the US dollar. USDS succeeds the original DAI stablecoin. A key innovation is the Sky Savings Rate (SSR), which automatically distributes a portion of the protocol's revenue to USDS holders as variable interest, creating a native yield mechanism. The protocol generates revenue through stability fees from loans, yield from real-world asset (RWA) allocations, and liquidation penalties (hereislokk).
3. Modular Ecosystem & "Stars" Model
Sky is designed as a modular ecosystem. Its core governance and stablecoin issuance are supplemented by autonomous sub-DAOs called "Sky Stars." Projects like Spark are examples of these Stars, which operate independently to develop new products (e.g., lending markets) while being economically aligned with and contributing value back to the main Sky Protocol (ChangeHero). This structure aims to foster innovation and scalability.
Conclusion
Fundamentally, Sky is a next-generation DeFi ecosystem built around a yield-generating stablecoin (USDS) and governed by a decentralized community through its SKY token. How will its modular "Stars" model drive the next wave of decentralized financial products?
