Sky (SKY) Cryptocurrency: Comprehensive Overview
Core Definition and Evolution
Sky (SKY) is a decentralized finance (DeFi) governance token representing the evolved version of MakerDAO, one of the oldest and most influential protocols in decentralized finance. Launched in 2024 as part of founder Rune Christensen's "Endgame" plan, Sky represents a complete transformation of the MakerDAO ecosystem designed to simplify governance, improve user experience, and scale DeFi infrastructure while maintaining non-custodial control over user assets.
Key distinction: MakerDAO and Sky are not separate projects—Sky is the evolved version of MakerDAO. The original MKR and DAI tokens remain in existence, but users can voluntarily upgrade to the new tokens, preserving backward compatibility while enabling the ecosystem to move forward.
Blockchain Architecture and Technology
Primary Infrastructure
Sky operates as a collateralized debt protocol built on the Ethereum blockchain:
| Component | Details | |
|---|---|---|
| Primary Blockchain | Ethereum mainnet | |
| Contract Address | 0x56072c95faa701256059aa122697b133aded9279 | |
| Decimals | 18 | |
| Cross-Chain Support | Solana, Layer 2 networks (Base, Arbitrum, Optimism, Unichain) |
Smart Contract Architecture
Sky's technology stack is built around non-custodial smart contracts:
- Collateralized Debt Position (CDP) Smart Contracts: Users deposit crypto collateral (such as ETH) into smart contracts to mint USDS stablecoin
- Vault Management System: Enables users to manage their collateral positions and maintain required overcollateralization ratios
- Stability Mechanisms: Automated systems maintain USDS's $1 peg through overcollateralization and smart incentives
- Security: Audited by reputable third-party security firms with non-custodial architecture ensuring users maintain full control
Cross-Chain Expansion: SkyLink
Sky has expanded beyond Ethereum through SkyLink, a bridge infrastructure enabling:
- Access to Sky features across multiple blockchains
- Cheaper and faster transactions on Layer 2 networks
- USDS availability on Solana and Ethereum Layer 2s
- Seamless liquidity provision across chains
Dual-Token System and Core Use Cases
SKY Token (Governance Token)
Primary Functions:
- Governance Voting: SKY holders vote on critical protocol parameters including collateral types, stability fees, protocol upgrades, and treasury allocations
- Staking Rewards: SKY holders can stake tokens to earn USDS rewards while delegating governance voting rights
- Borrowing Collateral: Stakers can borrow USDS against their staked SKY
- Risk Management: New SKY can be minted in undercollateralization events to maintain protocol stability
- Deflationary Mechanism: Protocol buybacks remove SKY from circulation (over $96 million spent on buybacks since 2025, removing 5.5% of supply)
USDS Stablecoin (Yield-Bearing Stablecoin)
Key Characteristics:
- Soft-pegged to US Dollar: Maintains $1 peg through protocol mechanisms
- Yield Generation: Users can deposit USDS into the Sky Savings Rate (SSR) to earn variable interest (currently 4.00%)
- Overcollateralization: Backed by overcollateralized crypto assets and real-world assets (RWAs)
- Convertibility: 1:1 conversion from legacy DAI token
- Regulatory Feature: Includes a freeze function allowing Sky to halt transfers from specific wallets for regulatory compliance and combating criminal activity
Real-World Applications
For Individual Users:
- Deposit crypto collateral to generate stablecoin liquidity without selling assets
- Earn yield on USDS holdings through the Sky Savings Rate
- Participate in governance through SKY token voting
- Access DeFi services across multiple blockchains via SkyLink
For Institutions:
- Banks (Societe Generale, Huntington Valley Bank) have tested the protocol
- $2 billion in real-world assets backing the protocol
- Integration with retail platforms (Kraken DeFi Earn, Robinhood)
- Institutional-grade collateral management and risk frameworks
Project History and Founding Team
Timeline of Evolution
2015: MakerDAO founded by Rune Christensen as one of the first DeFi protocols to achieve product-market fit with its DAI stablecoin.
2023: MakerDAO faced significant challenges:
- Governance complexity from monolithic community structure
- Scaling limitations preventing pursuit of market opportunities
- User accessibility issues for mainstream adoption
August 27, 2024: MakerDAO officially announced its rebrand to Sky, marking the beginning of Phase One of the Endgame roadmap.
September 18, 2024: Sky launched its new tokens and dApp (Sky.money):
- MKR to SKY conversion: 1 MKR = 24,000 SKY (redenomination designed to make governance more accessible)
- DAI to USDS conversion: 1:1 ratio
May 2025: Sky Protocol completed its Endgame transition, retiring the MKR token and launching SKY as the sole governance asset.
June 2025: SPK token launched with 10 billion tokens minted at genesis, representing the first governance token for a Sky Star (Spark).
October 2025: Sky Protocol completed a $10 million Series A funding round targeting mainnet upgrades, developer ecosystem growth, and institutional integration.
December 2025: Delayed Upgrade Penalty began ramping up (starting at 1%, increasing 1% quarterly) to incentivize remaining MKR holders to complete their migration to SKY.
Founding Leadership
Rune Christensen serves as the primary founder and visionary behind both MakerDAO and Sky. While governance is designed to be decentralized, Christensen holds 9% of governance tokens with effective control due to low voter turnout—a governance concentration concern noted by S&P Global Rating in August 2025.
Tokenomics and Supply Mechanics
SKY Token Supply Structure
| Metric | Value | |
|---|---|---|
| Circulating Supply | ~23.00 Billion SKY | |
| Total Supply | ~23.46 Billion SKY | |
| Max Supply | 23.46 Billion SKY (fixed) | |
| Current Price | $0.0667 USD | |
| Market Cap | $1.53 Billion | |
| Market Rank | #50 globally |
Supply Mechanics
Fixed Maximum Supply: Unlike many cryptocurrencies with ongoing inflation, SKY has a capped maximum supply of 23.46 billion tokens, creating a deflationary long-term structure.
Redenomination Ratio: The 1 MKR = 24,000 SKY conversion was designed to:
- Make governance participation more accessible (smaller token amounts feel more meaningful)
- Improve user experience and token psychology
- Maintain equivalent voting power across the transition
Deflationary Mechanisms:
- Protocol Buybacks: Sky has spent over $96 million on SKY buybacks since 2025, removing 5.5% of supply from circulation
- Staking Rewards: Funded through protocol revenue, creating a sustainable reward mechanism without dilution
- No Ongoing Inflation: Unlike MKR's previous inflationary model, SKY operates with a fixed supply
USDS Stablecoin Supply
- Current Market Cap: ~$10-11 billion (third-largest stablecoin)
- 2026 Target: Nearly double to $20.6 billion
- Backing: Overcollateralized by crypto assets and $2 billion in real-world assets
Consensus Mechanism and Network Security
Governance-Based Security Model
Sky operates on Ethereum's Proof of Work consensus mechanism but implements its own governance security layer:
Decentralized Governance Framework:
- Sky Atlas: A comprehensive rulebook for governance processes
- On-Chain Voting: SKY holders vote directly on protocol parameters
- Aligned Voter Committees (AVCs): Improve governance participation and decision-making efficiency
- Transparent Processes: All governance decisions documented and publicly accessible
Risk Management Architecture
Collateralization Requirements:
- Users must maintain minimum collateralization ratios to prevent liquidation
- Protocol automatically manages liquidations to maintain system stability
- Smart contracts enforce these requirements without human intervention
Stability Mechanisms:
- Overcollateralization ensures USDS remains backed by sufficient assets
- Stability fees incentivize users to maintain healthy positions
- Governance-voted parameters adjust based on market conditions
Governance Concerns and Centralization Risks
According to S&P Global Rating (August 2025):
- Founder Rune Christensen holds 9% of governance tokens but has effective control due to low voter turnout
- Concentrated user base with deposits from small group of users
- Governance still in transition phase
- S&P assigned a B-minus credit rating with stable outlook (speculative grade)

Risks and Challenges
Governance Concentration
Despite decentralized governance design, founder Rune Christensen's 9% token holding provides effective control due to low voter turnout. This concentration risk contradicts the protocol's decentralization goals.
USDS Freeze Function Controversy
The freeze function allowing Sky to halt transfers from specific wallets represents a departure from DAI's pure decentralization. While necessary for regulatory compliance and combating criminal activity, it has been controversial among DeFi purists who view it as compromising non-custodial principles.
Risk Management Concerns
- Aave Delisting (December 2025): Aave voted to delist USDS due to changing risk profile of collateral, indicating institutional concerns about protocol risk
- stUSDS Yield Concerns: The stUSDS product offers yields up to 40% with SKY collateral, with protocol subsidies above 20%—analysts view this as aggressive and potentially unsustainable
- Liquidation Disabled: Manual rate setting and disabled liquidations raise long-term trust concerns about protocol stability
Regulatory Uncertainty
- Stablecoins face evolving regulatory frameworks globally
- US regulatory environment particularly uncertain for DeFi protocols
- Geoblocking of US users from certain farming and yield opportunities limits addressable market
Concentrated User Base
S&P Global Rating noted that deposits come from a small group of users, creating concentration risk if major users withdraw liquidity.
Summary
Sky represents a significant evolution in decentralized finance, transforming MakerDAO from a complex, monolithic protocol into a modular, user-friendly ecosystem. The rebranding and token upgrades (MKR→SKY, DAI→USDS) are designed to improve accessibility, governance efficiency, and scalability while maintaining core principles of decentralization and non-custodial control.
The protocol demonstrates strong fundamentals with substantial TVL ($18.3 billion), growing user adoption (720,663 users), and ambitious 2026 growth projections ($611.5 million projected revenue). However, it faces challenges including governance concentration, risk management concerns, regulatory uncertainty, and the controversial USDS freeze function. The success of Sky will depend on executing its ambitious roadmap, maintaining user trust, and navigating an increasingly complex regulatory environment for stablecoins and DeFi protocols.
