What is SKY?

• SKY is the native governance and utility token of the Sky Protocol, the decentralized finance (DeFi) ecosystem that represents the rebranded and structurally upgraded evolution of MakerDAO. Launched in late 2024 as part of the ambitious "Endgame" transformation, the transition saw the legacy MKR token convert to SKY at a 1:24,000 ratio, while the DAI stablecoin was upgraded to USDS.

• By March 2026, Sky has shifted from a monolithic lending protocol into a modular ecosystem powered by "Sky Stars" (independent sub-DAOs like Spark). The protocol operates like a decentralized central bank, focusing on scaling its stablecoin through real-world asset (RWA) backing and aggressive tokenomic buybacks.

Risks Associated to the Digital Asset

• Financial Sustainability & Yield Risk: A primary risk for Sky involves balancing growth incentives with protocol profitability. In early 2025, the protocol famously posted a $5 million quarterly loss due to an unsustainable 12.5% yield payout on USDS, designed to drive adoption. While the Sky Savings Rate (SSR) has since been adjusted down to more sustainable levels (around 4.5% to 6.25%), the protocol faces ongoing pressure to maintain yield competitiveness against traditional finance and rivals like USDT/USDC without draining its treasury.

• Market Volatility & Concentration Risk: SKY is subject to significant price fluctuations. As of March 2026, the token's ownership remains highly concentrated, with a small number of "whale" wallets holding a material portion of the circulating supply. This concentration poses a risk of high volatility and potential large-scale sell-offs that can impact market stability.

• Regulatory & Legal Risk: As a major DeFi protocol handling billions in stablecoin liquidity, Sky faces ongoing regulatory scrutiny. The transition of the stablecoin from DAI to USDS introduced a "freezing function," allowing for centralized intervention in cases of theft or error. While this improves security, it has drawn debate regarding decentralization and may attract closer oversight from global regulators (e.g., EU MiCA or U.S. stablecoin laws).

• Technological & Upgrade Risk: The "Endgame" strategy involves complex architectural shifts, including the creation of Sky Stars (independent sub-projects like Spark). Any technical vulnerabilities in the new smart contract layers or failures in the modular "Star" governance model could lead to financial loss or protocol instability.

• Migration & Incentive Risk: The value of SKY is tied to the successful migration of users from the legacy MKR token (at a conversion rate of 1:24,000). A "Delayed Upgrade Penalty" was introduced in late 2025 to incentivize this shift. If community participation remains low or the incentive structures fail to maintain the USDS peg, the protocol’s revenue and the utility of the SKY token could diminish.

Trading History of Digital Asset

• Market Capitalization & Liquidity: As of March 16, 2026, SKY has a market capitalization of approximately $1.69 billion to $1.70 billion, ranking it around #40–#51 globally. It maintains robust liquidity on major exchanges such as Coinbase, Binance, and Bybit, with 24-hour trading volumes typically ranging from $12 million to $31 million.

Incidents of Manipulation or Security Failures

• Sky (SKY) operates as the governance and utility core of the Sky Protocol, which is the decentralized evolution of MakerDAO. By March 2026, the protocol has moved beyond its initial rebranding into the "Endgame" Phase 2, characterized by a modular, "star-based" architecture designed for high scalability and automated risk management.

• Incidences of Manipulation or Security Failures: The Sky Protocol maintains one of the highest security ratings in the industry, having inherited MakerDAO’s 100% uptime record.

  • Operational Resilience: In February 2026, the protocol successfully mitigated a sophisticated "governance exhaustion" attempt where a large group of wallets tried to spam the voting system to delay a critical interest rate adjustment. The Governance Delay Buffer (a 48-hour mandatory wait period) prevented the malicious parameters from being implemented.

  • RWA Transparency: As of March 2026, over $2.1 billion of the protocol's backing comes from Real-World Assets. To prevent manipulation, Sky uses Proof of Reserve (PoR) oracles that provide real-time audits of the off-chain bank accounts and bond portfolios backing USDS, ensuring that the "paper" value matches the on-chain representation.

Token Ownership Concentration

SKY’s tokenomics are designed to encourage broad participation but currently show high concentration:

• Max Supply: Approximately 23.46 billion tokens.

• Circulating Supply: As of March 2026, roughly 23.1 billion SKY (98%) is in circulation.

• Concentration: Data from 2026 indicates that 85.6% of the supply is held by the top 10 wallets.

• Deflationary Buybacks: The protocol actively uses surplus revenue (generated from stability fees) to buy back SKY. Since early 2025, over $100 million has been deployed to repurchase and remove SKY from circulation, supporting its market value.

Security Audit

Sky (formerly Maker) is a highly complex multichain Decentralized Finance protocol and foundational overcollateralized stablecoin issuer deployed primarily on the Ethereum network. Following the Maker→Sky rebrand, the ecosystem now issues USDS as the next-generation stablecoin within the Sky architecture, positioned as the upgraded successor to DAI while both tokens continue to coexist during the transition. Because the protocol manages billions of dollars in decentralized collateral vaults and stablecoin liabilities without traditional centralized intermediaries, the Sky ecosystem has engaged multiple top-tier blockchain security firms to audit successive generations of its smart contract architecture.

Protocol-Level Security Audits

Sky engages top-tier security firms across all major protocol versions:

• ChainSecurity;

• Trail of Bits;

• OpenZeppelin.

These rigorous protocol-level audits meticulously analyze:

• Core Vault mechanics and collateral management;

• Liquidation and risk modules;

• Token converter mechanisms;

• Ecosystem migration infrastructure;

• Resilience against unauthorized minting exploits;

• Protection against reentrancy vulnerabilities;

• Defense against catastrophic collateral drains.

Stablecoin Architecture and Dual Token Transition:

DAI and USDS Coexistence:

• Legacy DAI continues in ecosystem;

• New USDS represents next-generation stablecoin;

• Both tokens coexist during transition period;

• Immutable ERC-20 token converters facilitate ecosystem migration;

• Fixed conversion rate between legacy MKR and new SKY governance token;

• Audited converter mechanisms ensure safe transition.
