USDS

What Is USDS?

USDS is a decentralized, U.S. dollar-pegged stablecoin issued by the Sky Protocol, the rebranded successor to the pioneering MakerDAO project. Designed to trade as close to $1.00 as possible, USDS currently has a market capitalization of roughly $9.86 billion, placing it around rank #12 among all cryptocurrencies, with a price near $0.9999 and about $193.7 million in 24-hour trading volume. As one of the largest decentralized stablecoins in existence, USDS sits alongside centralized giants such as Tether and USD Coin as core settlement and collateral money for on-chain finance.

The core problem USDS attempts to solve is the same one that has driven the entire stablecoin sector: cryptocurrencies like Bitcoin and Ethereum are too volatile to serve as everyday units of account, collateral, or savings instruments. USDS offers a price-stable, blockchain-native dollar that can be minted against crypto and real-world collateral, moved permissionlessly across wallets and exchanges, and used throughout decentralized finance for lending, trading, and payments without relying solely on a bank-custodied fiat reserve model.

History and Founders

USDS traces its lineage directly to MakerDAO, one of the earliest and most influential decentralized finance protocols on Ethereum. MakerDAO was one of the first decentralized self-reliant companies (DAO) on the Ethereum blockchain, and since 2015 Rune Christensen has focused on setting up the vision and organizational shape of the Maker Decentralized autonomous company and the financial foundations of the Dai stable digital currency. MakerDAO issues Dai, the world’s first stablecoin on the Ethereum blockchain, which gets rid of volatility through smart contracts designed to respond to market dynamics. Rune Christensen, who studied biochemistry and international business in Copenhagen, co-founded MakerDAO and steered it through more than a decade of growth, governance battles, and expansion into real-world-asset collateral.

In 2024, Maker governance approved a sweeping restructuring known as the “Endgame” plan. As part of this overhaul, MakerDAO rebranded itself as Sky, the MKR governance token was succeeded by a new token called SKY, and a new, more flexible stablecoin—USDS—was introduced to sit alongside the original DAI token rather than replace it outright. Holders of DAI and MKR were given the option to upgrade to USDS and SKY at fixed ratios, while DAI itself continues to exist and remains freely convertible with USDS. The rebrand was pitched by Christensen and the Sky team as a way to modernize the protocol’s branding, improve regulatory positioning, and open the door to a broader ecosystem of semi-independent “Sky Stars”—specialized subprotocols that can innovate on top of the core Sky lending and stablecoin engine without being constrained by the pace of the main DAO’s governance process.

How the Technology Works

USDS is generated in much the same way DAI historically was: users lock collateral into on-chain vaults and borrow newly minted USDS against it, with the debt plus a stability fee owed upon withdrawal of the collateral. If the value of the posted collateral falls too far relative to the outstanding USDS debt, the position can be liquidated to keep the system solvent. Unlike the original single-collateral Dai model, the modern Sky system accepts a diversified basket of backing assets, including established crypto assets such as staked ETH derivatives and wrapped Bitcoin, as well as tokenized real-world assets like short-term U.S. Treasury bills and other low-risk debt instruments sourced through partner institutions. This diversified, partly off-chain collateral base is intended to generate more stable and often higher yield than purely crypto-backed designs, while still maintaining on-chain transparency about reserves.

A companion token, sUSDS, allows holders to deposit USDS into a savings module and earn a variable yield generated by the protocol’s collateral portfolio and lending activity—functionally similar to the original DAI Savings Rate. Governance of the protocol, including collateral onboarding, risk parameters, and fee levels, is conducted by SKY token holders voting on proposals, continuing Maker’s long tradition of on-chain DAO governance. Because USDS is deployed primarily as an ERC-20 token on Ethereum, it integrates natively with the broader Ethereum DeFi stack, including automated market makers, lending markets, and bridges to other chains.

Tokenomics and Supply

USDS supply is elastic rather than fixed: new tokens are minted whenever a user opens a collateralized borrowing position or converts DAI into USDS, and tokens are burned when debts are repaid or USDS is converted back. This mint-and-burn mechanism means the circulating supply expands and contracts with borrowing demand and market appetite for holding the stablecoin, rather than following a pre-set emission schedule. At current market data, USDS has a market capitalization of approximately $9,858,907,989, ranking it roughly #12 among all cryptocurrencies by that measure, with a price that hovers extremely close to its $1.00 target and average daily trading volume near $193.7 million. Because USDS trades near parity with the dollar, market capitalization is a close proxy for the total dollar value of USDS in circulation at any given time.

Notable Milestones and Controversies

The transition from Maker/DAI to Sky/USDS ranks among the most significant rebranding events in DeFi history, given the multi-billion-dollar scale of the protocol being renamed. The move followed years of internal debate within the Maker community about the “Endgame” restructuring, which split the protocol into multiple semi-autonomous “Stars” (such as the Spark lending protocol) intended to accelerate product development while insulating the core protocol from excessive risk-taking in any single subunit.

The rebrand and associated token migration were not without controversy. Segments of the community objected to the SKY/MKR conversion terms, to the perceived dilution of MakerDAO’s brand equity built up since 2017, and to the increasing reliance on real-world-asset collateral—particularly short-term Treasury exposure—which critics argued reintroduced centralization and counterparty risk into a protocol originally designed around trustless crypto collateral. Some long-time MKR holders and community members publicly opposed the rebrand, arguing it represented a governance takeover risk and an erosion of the DAO’s founding decentralization principles. Christensen has defended the changes as necessary for the protocol’s long-term competitiveness against centralized stablecoin issuers and newer DeFi entrants such as Figure Heloc and other tokenized-credit projects.

Ecosystem and Use Cases

USDS and its yield-bearing counterpart sUSDS circulate widely across decentralized exchanges, lending markets, and treasury-management tools built on Ethereum and compatible networks. The token is commonly paired against other major stablecoins and blue-chip assets like BNB, Solana, and TRON-based tokens on cross-chain venues, and it is accepted as collateral on major lending protocols. The Spark Protocol, one of the flagship “Sky Stars,” channels USDS liquidity into lending markets and yield strategies, while other Stars are being incubated to expand the ecosystem into new verticals such as institutional credit and cross-chain liquidity provisioning.

Because it descends from DAI, USDS inherits deep liquidity and integration across the DeFi landscape that took years to build, including listings on major centralized and decentralized exchanges and support in most major self-custody wallets.
