The protocol scheduled the launch of USDS (alongside the new SKY governance token, which replaced MKR at a 1:24,000 ratio) for September 18, 2024. DAI holders were offered a voluntary, 1:1 upgrade path to USDS, with the reverse conversion also supported; legacy DAI and MKR balances were not forcibly migrated and remained usable indefinitely. In the months that followed, major exchanges progressively shifted liquidity toward USDS: reporting from April 2026 describes exchanges such as Binance and Bitunix delisting DAI trading pairs in favor of USDS pairs, with one industry account characterizing the cumulative shift, affecting roughly $7.9 billion in liabilities, as 'the largest stablecoin conversion in crypto history.' Because migration was opt-in rather than mandatory, DAI and USDS have continued to coexist as parallel tokens, which some commentators say adds to brand and liquidity fragmentation across the Sky ecosystem.","heading":"Origin and DAI-to-USDS Migration","severity":"low","sources":[{"credibility":2,"name":"MakerDAO becomes SKY: the launch of the stablecoin USDS - Cryptonomist","type":"news_article","url":"https://en.cryptonomist.ch/2024/08/28/the-makerdao-protocol-undergoes-a-rebranding-and-becomes-sky-in-september-the-launch-of-the-stablecoin-usds/"},{"credibility":2,"name":"MakerDAO Rebrands To \"Sky\" and Schedules USDS Stablecoin Launch - The Defiant","type":"news_article","url":"https://thedefiant.io/news/defi/makerdao-schedules-sky-rebrands-and-usds-stablecoin-launch"},{"credibility":2,"name":"DAI-to-USDS Migration Goes Live April 7: The Largest Stablecoin Conversion in Crypto History - BlockEden.xyz","type":"research","url":"https://blockeden.xyz/blog/2026/04/03/dai-usds-migration-makerdao-sky-protocol-stablecoin-rebrand/"},{"credibility":2,"name":"MakerDAO rebrands to Sky, DAI stablecoin optionally upgradeable to USDS - The Block","type":"news_article","url":"https://www.theblock.co/post/313235/makerdao-mkr-sky-dai-stablecoin-usds"}]},{"content":"USDS is described by Sky as an over-collateralized stablecoin, with every unit backed by collateral held in on-chain Sky vaults rather than a simple fiat reserve. The collateral mix is reported to combine crypto assets, USDC obtained through peg stability modules (PSMs), and real-world assets (RWA) sourced through Treasury-focused vaults. Industry summaries describe the backing as diversified across categories including stablecoin reserves (USDC, USDT, and PYUSD) held across PSM structures and lending positions, on-chain crypto lending with automated liquidation, short-duration U.S. Treasury bills deployed by so-called 'Sky Agents,' and OTC crypto lending arrangements. Sky's allocation to tokenized U.S. Treasuries, arranged through partners including Monetalis and BlockTower, was reported to have exceeded $1.5 billion by early 2026. Sky states that a live breakdown of collateral positions is published at its financial transparency dashboard; this claim is self-reported by the protocol and has not been independently audited by a third party in the sources reviewed for this report, so figures should be treated as protocol-disclosed rather than externally verified.","heading":"Collateralization Model and Reserve Composition","severity":"medium","sources":[{"credibility":3,"name":"Inside Sky: DAI and USDS Architecture - Eco","type":"research","url":"https://eco.com/support/en/articles/14796323-inside-sky-dai-and-usds-architecture"},{"credibility":3,"name":"sUSDS Explained: Sky's Savings Rate Token - Eco","type":"research","url":"https://eco.com/support/en/articles/14798655-susds-explained-sky-s-savings-rate-token"},{"credibility":2,"name":"A Guide To Stablecoins: Multi-Collateral-Backed Stablecoins—DAI, USDS - ARK Invest","type":"research","url":"https://www.ark-invest.com/articles/analyst-research/multi-collateral-backed-stablecoins-dai-usds"}]},{"content":"USDS maintains a target 1:1 peg to the U.S. dollar. Because a significant share of its backing flows through peg stability modules priced against USDC, analysts note that USDS carries structural pass-through depeg risk: if USDC itself were to depeg, as it briefly did during the March 2023 Silicon Valley Bank crisis (when USDC traded as low as roughly $0.88 before recovering), USDS could be expected to move with it for the duration of the dislocation. No sources reviewed document a sustained, material depeg of USDS itself since its September 2024 launch. This section should be read as describing a structural risk factor rather than a realized event.","heading":"Peg Stability and USDC Pass-Through Risk","severity":"medium","sources":[{"credibility":3,"name":"USDS Sky Protocol: 2026 Yield Guide - Eco","type":"research","url":"https://eco.com/support/en/articles/11752998-usds-sky-protocol-2026-yield-guide"}]},{"content":"The introduction of USDS was accompanied by controversy over a built-in freeze capability that would allow transactions or balances tied to specific wallets to be blocked, a feature DAI never had. Critics on Sky's governance forum argued the change undermined the neutrality and censorship-resistance that had defined DAI. Sky co-founder Rune Christensen said the freeze function would not be active at USDS's September 2024 launch, only an 'upgrade' function, and that whether and how to implement freezing would be left to future governance votes requiring community approval. Christensen has publicly defended the feature as necessary for Sky to hold real-world assets and participate in regulated financial channels at scale, noting that competitors such as USDT and USDC already have comparable mechanisms. Sky subsequently introduced a structure of semi-autonomous regional entities ('Sky Stars') intended to manage localized regulatory compliance. Commentators have nonetheless characterized the freeze capability as pushing USDS toward a more centralized, USDT/USDC-like trust model, in tension with Sky's origins as a decentralized stablecoin issuer.","heading":"Freeze Function and Centralization Criticism","severity":"high","sources":[{"credibility":2,"name":"Christensen Balances New Sky Governance With User Choice Amid Freeze Function Debate - Decrypt","type":"news_article","url":"https://decrypt.co/248173/christensen-sky-governance-freeze-function-debate"},{"credibility":3,"name":"Sky stablecoin USDS faced fierce criticism due to the 'freeze function' - Moomoo News","type":"news_article","url":"https://www.moomoo.com/news/post/42988487/sky-stablecoin-usds-faced-fierce-criticism-due-to-the-freeze"},{"credibility":2,"name":"MakerDAO's Rebranding to Sky Fuels Decentralization Concerns - BeInCrypto","type":"news_article","url":"https://beincrypto.com/makerdao-sky-rebranding-defi-community-responds/"}]},{"content":"In December 2024, Cointelegraph reported that Sky faced scrutiny after an anonymous X (Twitter) user flagged that roughly $756 million in USDC reserves backing USDS, held within Sky's 'lite' peg stability module, were controlled through an externally-owned account (EOA) — a standard private-key-controlled wallet — rather than a multisignature or time-locked structure. Critics argued this concentration of control created a single point of failure, exposing the reserves to risk if the controlling private key were compromised or misused. Rune Christensen responded that the private keys needed to reconstitute the underlying multiparty-computation (MPC) account had been destroyed as part of a setup process conducted with Coinbase Custody, intended to foreclose the possibility of unilateral reconstruction. According to Cointelegraph, Christensen did not fully clarify who held day-to-day authorization control over the account, how transactions were approved, or whether on-chain governance had binding enforcement power over the funds, and did not respond to follow-up questions before publication. Sky said reserves were being migrated from the older PSM to the lite PSM in phases, with an initial $20 million transfer.","heading":"Reserve Custody Concerns: $756M EOA Controversy","severity":"high","sources":[{"credibility":2,"name":"Sky faces scrutiny over potential $756M exploit flaw - Cointelegraph","type":"news_article","url":"https://cointelegraph.com/news/sky-lite-psm-eoa-security-usdc-reserves"},{"credibility":2,"name":"Sky faces scrutiny over potential $756M exploit flaw - TradingView (Cointelegraph syndication)","type":"news_article","url":"https://www.tradingview.com/news/cointelegraph:3879ef385094b:0-sky-faces-scrutiny-over-potential-756m-exploit-flaw/"},{"credibility":3,"name":"Sky: risks for an exploit of $756 million in USDC reserves - Cryptonomist","type":"news_article","url":"https://en.cryptonomist.ch/2024/12/06/sky-under-accusation-risks-for-an-exploit-of-756-million-dollars-in-usdc-reserves/"}]},{"content":"USDS operates within Sky's broader 'Endgame' plan, approved by MKR governance in 2023 and rolled out through 2024–2026, which restructured the protocol around USDS as the primary token, SKY as the governance token, and a set of semi-independent 'Stars' (subDAOs, such as the SparkLend lending arm and dedicated RWA vault operators) each with its own token and operational scope. Commentators have described the resulting structure as adding substantial governance complexity and brand confusion, with DAI, USDS, MKR, and SKY all continuing to circulate simultaneously, and with revenue increasingly dependent on traditional-finance instruments such as Treasury bonds and corporate credit rather than purely on-chain crypto collateral. Sky's own initial rebrand proposal reportedly faced internal pushback, including at least one earlier vote in which parts of the rebranding plan were rejected amid centralization concerns, before the Sky/USDS/SKY branding was ultimately adopted.","heading":"Endgame Restructuring and Governance Complexity","severity":"medium","sources":[{"credibility":2,"name":"MakerDAO's Rebranding to Sky Fuels Decentralization Concerns - BeInCrypto","type":"news_article","url":"https://beincrypto.com/makerdao-sky-rebranding-defi-community-responds/"},{"credibility":2,"name":"Sky or Maker?

Implementing regulations were expected through 2026–2027. No source reviewed for this report documents an SEC enforcement action, lawsuit, or formal regulatory finding specifically naming USDS or Sky as of this writing; Sky's freeze-function rollout and Stars/regional-compliance structure have been publicly framed by Christensen as preparation for operating within frameworks like the GENIUS Act rather than as a response to any specific enforcement action.","heading":"Regulatory Context","severity":"low","sources":[{"credibility":1,"name":"The GENIUS Act: A New Era of Stablecoin Regulation - Gibson Dunn","type":"research","url":"https://www.gibsondunn.com/the-genius-act-a-new-era-of-stablecoin-regulation/"},{"credibility":1,"name":"The GENIUS Act: A Comprehensive Guide to US Stablecoin Regulation - Paul Hastings","type":"research","url":"https://www.paulhastings.com/insights/crypto-policy-tracker/the-genius-act-a-comprehensive-guide-to-us-stablecoin-regulation"}]}],"sources_used":[{"credibility":2,"name":"MakerDAO becomes SKY: the launch of the stablecoin USDS - Cryptonomist","type":"news_article","url":"https://en.cryptonomist.ch/2024/08/28/the-makerdao-protocol-undergoes-a-rebranding-and-becomes-sky-in-september-the-launch-of-the-stablecoin-usds/"},{"credibility":2,"name":"MakerDAO Rebrands To \"Sky\" and Schedules USDS Stablecoin Launch - The Defiant","type":"news_article","url":"https://thedefiant.io/news/defi/makerdao-schedules-sky-rebrands-and-usds-stablecoin-launch"},{"credibility":2,"name":"MakerDAO rebrands to Sky, DAI stablecoin optionally upgradeable to USDS - The Block","type":"news_article","url":"https://www.theblock.co/post/313235/makerdao-mkr-sky-dai-stablecoin-usds"},{"credibility":2,"name":"DAI-to-USDS Migration Goes Live April 7: The Largest Stablecoin Conversion in Crypto History - BlockEden.xyz","type":"research","url":"https://blockeden.xyz/blog/2026/04/03/dai-usds-migration-makerdao-sky-protocol-stablecoin-rebrand/"},{"credibility":3,"name":"Inside Sky: DAI and USDS Architecture - Eco","type":"research","url":"https://eco.com/support/en/articles/14796323-inside-sky-dai-and-usds-architecture"},{"credibility":3,"name":"sUSDS Explained: Sky's Savings Rate Token - Eco","type":"research","url":"https://eco.com/support/en/articles/14798655-susds-explained-sky-s-savings-rate-token"},{"credibility":2,"name":"A Guide To Stablecoins: Multi-Collateral-Backed Stablecoins—DAI, USDS - ARK Invest","type":"research","url":"https://www.ark-invest.com/articles/analyst-research/multi-collateral-backed-stablecoins-dai-usds"},{"credibility":3,"name":"USDS Sky Protocol: 2026 Yield Guide - Eco","type":"research","url":"https://eco.com/support/en/articles/11752998-usds-sky-protocol-2026-yield-guide"},{"credibility":2,"name":"Christensen Balances New Sky Governance With User Choice Amid Freeze Function Debate - Decrypt","type":"news_article","url":"https://decrypt.co/248173/christensen-sky-governance-freeze-function-debate"},{"credibility":3,"name":"Sky stablecoin USDS faced fierce criticism due to the 'freeze function' - Moomoo News","type":"news_article","url":"https://www.moomoo.com/news/post/42988487/sky-stablecoin-usds-faced-fierce-criticism-due-to-the-freeze"},{"credibility":2,"name":"MakerDAO's Rebranding to Sky Fuels Decentralization Concerns - BeInCrypto","type":"news_article","url":"https://beincrypto.com/makerdao-sky-rebranding-defi-community-responds/"},{"credibility":2,"name":"Sky or Maker?
