What is Sky (SKY)?

Deep Dive

1. Evolution from MakerDAO

Sky Protocol is the direct successor to MakerDAO, a foundational DeFi lending platform launched in 2015. The rebrand to "Sky" and "Endgame" transition, completed in 2024, marked a shift from a single-protocol model to a scalable ecosystem (ChangeHero). The legacy MKR governance token was upgraded to SKY at a 1:24,000 ratio to broaden governance participation.

2. USDS Stablecoin & The Savings Rate

The ecosystem's engine is the USDS stablecoin, the successor to DAI. Unlike many stablecoins, USDS is designed to be "DeFi-native," offering a built-in yield mechanism. Holders can earn the Sky Savings Rate (SSR), a variable interest rate funded by the protocol's revenue from lending fees and real-world asset yields (Sky App). This makes USDS a leading yield-generating stablecoin.

3. Modular Architecture via "Sky Stars"

Sky scales through a modular framework. Independent projects, called Sky Stars (like Spark and Grove), operate as sub-DAOs (ChangeHero). They develop specialized products (e.g., lending, institutional credit) while borrowing USDS liquidity from the core protocol. This structure fosters innovation and diversifies revenue streams back to SKY stakeholders.

Conclusion

Fundamentally, Sky is a mature DeFi ecosystem that has transitioned from a single stablecoin issuer into a modular network focused on generating risk-adjusted yields. Its strength lies in a proven infrastructure, a revenue-generating stablecoin, and a scalable model for future growth. How will the expansion of its "Stars" further solidify its role as an on-chain financial hub?
