Sky is a leading decentralized lending platform built on blockchain technology, empowering users to generate stablecoins backed by digital assets. Formerly known as MakerDAO, Sky has evolved into one of the most influential players in the decentralized finance (DeFi) ecosystem since its inception in 2014. With its innovative approach to collateralized loans and stablecoin issuance, Sky continues to shape how users interact with crypto-based financial services.
At the heart of Sky’s ecosystem is DAI, a dollar-pegged stablecoin maintained through a combination of smart contracts, over-collateralization, and dynamic risk management systems. Unlike centralized stablecoins backed by fiat reserves, DAI achieves stability through decentralized mechanisms—making it a cornerstone of trustless finance.
How Sky Works: The Mechanics Behind Decentralized Lending
Sky operates on the Ethereum blockchain and enables users to lock up assets like ETH in smart contracts called Collateralized Debt Positions (CDPs), now known as Vaults. In return, users can generate DAI, which they can spend, trade, or hold without selling their underlying crypto holdings.
This system relies on over-collateralization, meaning users must deposit more in value than the DAI they wish to borrow. For example, to borrow $100 worth of DAI, a user might need to lock up $150 worth of ETH. This buffer protects the system during market volatility.

The stability of DAI is maintained through an autonomous feedback loop involving:
- Dynamic Stability Fees: Interest rates adjusted based on supply and demand for DAI.
- Liquidation Mechanisms: If collateral value drops too low, positions are automatically liquidated to preserve solvency.
- Oracle Feeds: Real-time price data ensures accurate valuation of collateral.
These mechanisms work together to keep DAI pegged to $1, even in turbulent markets—a remarkable achievement in decentralized finance.

Despite short-term fluctuations, MKR has shown strong long-term growth, reflecting increasing confidence in Sky’s governance and financial resilience.
Governance and the Role of MKR Token
The MKR token is central to Sky’s decentralized governance model. Holders of MKR vote on critical protocol decisions such as:
- Risk parameters for different collateral types
- Addition of new assets as collateral
- Protocol upgrades and emergency shutdowns
Because MKR holders are responsible for maintaining system integrity, they also bear downside risk—if the system becomes undercollateralized, new MKR tokens are minted and sold to cover losses, diluting existing holders. This creates strong incentives for prudent governance.
This unique mechanism aligns stakeholders around long-term sustainability rather than short-term speculation.

Frequently Asked Questions (FAQ)
What is Sky used for?
Sky enables users to borrow DAI—a stablecoin pegged to the US dollar—by locking up crypto assets as collateral. It also allows for decentralized governance via the MKR token, where holders vote on system parameters and upgrades.
Is Sky safe to use?
Yes, Sky employs multiple layers of security including over-collateralization, automated liquidations, and real-time price oracles. While no system is immune to risk—especially during extreme volatility—Sky has maintained stability through several market cycles.

How does DAI stay pegged to $1?
DAI maintains its peg through economic incentives and algorithmic controls. When DAI trades above $1, generating more DAI becomes profitable; when below $1, paying back debt at a discount encourages reduction in supply. These forces help balance supply and demand.
Can I earn interest with Sky?
Yes. Users can deposit DAI into various integrated platforms like Spark Protocol to earn yield. Additionally, some vaults offer special configurations that allow indirect yield generation on collateral.
Who controls Sky?
Sky is governed by MKR token holders through a decentralized autonomous organization (DAO). There is no central authority; all major decisions are made collectively by the community.
How is Sky different from traditional banks?
Unlike banks, Sky operates without intermediaries. Loans are issued automatically via smart contracts, accessible globally 24/7. There's no credit check—only sufficient collateral is required—making it inclusive and permissionless.
Why Sky Matters in the Future of Finance
Sky represents a paradigm shift in how financial services are delivered. By removing intermediaries and enabling open access to credit and savings tools, it supports financial inclusion for millions worldwide.
Its success has inspired countless other DeFi projects and demonstrated that transparent, code-based finance can function at scale.
As Ethereum continues to evolve with improvements in scalability and security, platforms like Sky are poised to reach even broader adoption—bridging traditional finance with the decentralized web.
