### What is Sky (SKY)?

Sky Protocol is a next-generation decentralised finance (DeFi) platform built to simplify saving, governance, and stablecoin management. It provides users with non-custodial access to DeFi tools that are designed to be more scalable, user-friendly, and transparent.

At its core, the protocol features **USDS**, a USD-pegged stablecoin that replaces DAI, and **SKY**, the governance and utility token that powers the ecosystem. Together, they form the foundation of a modern DeFi network focused on decentralised governance, on-chain yield, and cross-chain accessibility.

The **Sky Protocol architecture** introduces **Sky.money**, a non-custodial interface that allows users to manage savings, staking, and governance directly on-chain. The protocol operates primarily on Ethereum, with interoperability across other major networks like Cardano, and integrates a Layer-2 infrastructure known as **SkyLink** to deliver faster and more cost-efficient transactions.

**SKY** plays a central role in protocol governance and ecosystem alignment. Token holders vote on key parameters such as collateral types, stability fees, savings rates, and system upgrades through the decentralised **Sky.DAO**.

### How does Sky work?

Sky Protocol operates as a modular DeFi ecosystem that unites savings, governance, and yield-generation under a single, accessible framework.

#### Core components include:
- **USDS Stablecoin:** A fully decentralised, USD-pegged stablecoin that enables stable savings and lending.  
- **Sky Savings Rate (SSR):** A built-in yield system that allows USDS holders to earn returns directly on-chain.  
- **Staking Engine:** Enables SKY holders to stake their tokens to earn rewards, delegate governance power, and participate in protocol decisions.  
- **SkyLink Layer-2:** A fast and cost-efficient network extension that improves scalability and transaction efficiency.  
- **Sky.DAO:** The governance layer where SKY holders vote on proposals and manage protocol parameters such as fees, collateral, and system updates.  

Together, these elements make Sky a flexible and transparent alternative to traditional finance, empowering users to participate in a truly decentralised economy.

### SKY Token Utility

**SKY** serves as both the governance and economic engine of the Sky ecosystem. Its primary roles include:

- **Governance:** Voting on system upgrades, parameter changes, and protocol decisions through Sky.DAO.  
- **Staking & Rewards:** Earning incentives via staking, delegation, and participation in Sky Token Rewards (STRs) and Activation programs.  
- **Savings & Lending:** Accessing yield on stablecoin deposits through the Sky Savings Rate (SSR) and borrowing via the Spark lending platform.  
- **Cross-Chain Access:** Leveraging the SkyLink Layer-2 system to perform fast, low-cost DeFi transactions.  
- **Ecosystem Participation:** Supporting modular sub-projects and partnerships such as Spark, LCX Exchange, and Skybase International.  

These utilities position **SKY** as a cornerstone asset across DeFi, DAO governance, stablecoin-based finance, and institutional-grade decentralised systems.

### What is the history of Sky (SKY)?

Sky Protocol originated from **MakerDAO**, one of the pioneering projects in decentralised finance. In **2024**, the MakerDAO community initiated a full system transition, introducing **USDS** as the new stablecoin and **SKY** as the governance token to replace DAI and MKR.

The rebrand marked a shift toward a modular, more inclusive system focused on accessibility, scalability, and long-term sustainability. The redenomination of MKR to SKY allowed broader governance participation, while the introduction of **Sky.money** and **SkyLink** improved usability and network efficiency.

Since then, **Sky** has evolved into a global, community-driven DeFi ecosystem, combining the stability of **USDS**, the governance power of **SKY**, and a growing network of integrated products and partners that together represent the next evolution of decentralised finance.
