What Is USDS (Sky Dollar) and Is It the Same as Dogecoin?

USDS, also called Sky Dollar, is a decentralized stablecoin created by Sky Protocol, the rebranded and upgraded version of the MakerDAO project. It is designed to maintain a one-to-one peg with the US dollar and is backed by on-chain crypto assets and real-world assets. USDS should not be confused with Dogecoin: USDS is a stablecoin, while Dogecoin is an independent cryptocurrency with a market-driven value.

You may have come across USDS while researching stablecoins and wondered whether it is connected to Dogecoin. Here, we explain what USDS is, how it works, and how it differs from Dogecoin for Canadian readers.

What Is USDS (Sky Dollar)?

USDS, also referred to as Sky Dollar, is a decentralized stablecoin created by the Sky Protocol team. Its value is designed to stay pegged to one US dollar, backed by on-chain crypto assets and real-world collateral.

Unlike stablecoins backed by a single bank account, USDS is a crypto-backed native stablecoin. It is issued against on-chain collateral rather than bank reserves, which makes the issuance process transparent.

The Story Behind USDS: From MakerDAO to Sky

To understand USDS, it helps to look at its history. USDS is the new version of DAI, the first stablecoin of its kind in the crypto industry. DAI was launched in 2017 on MakerDAO’s decentralized finance protocol.

When the platform rebranded in August 2024, it became Sky Protocol. The rebrand introduced a dual-token system—USDS and SKY—replacing the previous DAI and MKR tokens. The goal was to build a broader ecosystem that extends beyond the protocol and offers a scalable, community-oriented product.

It’s important to note that DAI was not retired. You can still use DAI as a legacy coin, and you can exchange it 1:1 for USDS.

Is USDS the Same as Dogecoin?

It’s a common question among newcomers, since both terms come up during crypto research. The short answer: USDS and Dogecoin have nothing in common.

The first thing to understand about USDS is that it was designed to resist the volatility common in cryptocurrency markets, which is what makes it a stablecoin. Dogecoin, by contrast, is an ordinary cryptocurrency with a market-based price. Apart from both being cryptocurrencies, the two have nothing in common.

How Does USDS Work?

The protocol maintains the dollar peg through a collateralized minting system and modules known as Peg Stability Modules (PSMs). PSMs allow users to exchange USDS for other leading stablecoins directly and predictably, helping keep the token’s price close to one dollar.

Collateral Backing

The protocol mints USDS against a portfolio of on-chain crypto assets and real-world assets. This overcollateralized structure means the value behind the token exceeds its face value. Protocol data shows that more than $3 billion of USDS is backed by real-world assets, including a $500 million USDS-backed stablecoin mortgage signed in February 2026.

Peg Stability Modules

PSMs enable USDS to be traded with other stablecoins at a consistent ratio, supporting price stability and giving the token practical use across the DeFi sector.

Cross-Chain Availability

Besides Ethereum, USDS is available on several blockchain ecosystems through a bridge called SkyLink. According to Allium data from early August 2026, more than 98% of all USDS liquidity is on Ethereum, with smaller amounts on Arbitrum, Solana, and Base.

Earning Yield With USDS: The Sky Savings Rate

One of the standout features of USDS is the Sky Savings Rate (SSR). The program distributes a portion of protocol revenue to USDS holders who deposit their tokens into the savings module, providing automatic yield for those who want their stablecoin to generate income.

This feature helps USDS stand out from most other stablecoins, which typically require separate yield-generation strategies.

USDS and the SKY Governance Token

USDS is the stablecoin at the core of Sky Protocol, while SKY is the ecosystem’s independent governance and utility token. SKY replaced MKR as the protocol’s governance token at a conversion rate of 1 MKR = 24,000 SKY and plays an integral role in governance.

SKY holders can participate in on-chain governance and shape the future of Sky Protocol. SKY can also be used in reward programs such as Sky Token Rewards and Activation Rewards.

It is important to pay attention to the fact that SKY and USDS serve very different roles: USDS is designed for stability and use in DeFi applications, while SKY is tied to governance and ecosystem incentives.

What Can You Do With USDS?

Here are some of the things you can do with USDS:

• Earn interest: By depositing USDS into the Sky Savings Rate module, you can earn interest based on the protocol’s profitability.
• Trading and liquidity: USDS can be used in liquidity pools on various exchanges for trading.
• Governance: Holding USDS makes you part of the Sky ecosystem and allows you to participate in SKY governance.
• Cross chain operations: With SkyLink, you can move USDS between Arbitrum, Base, and Optimism with lower transaction fees than on Ethereum.
• On-chain stable value storage: As noted, USDS maintains a constant dollar value, letting users store value on-chain without price fluctuations.

How to Acquire and Hold USDS

You can buy USDS in a few standard ways, depending on your crypto preferences and the platforms you use.

1. Swap from DAI: If you own DAI, you can exchange it 1:1 for USDS through the Sky Protocol interface.
2. Exchange through Peg Stability Modules: USDS can be exchanged for popular stablecoins such as USDC or USDT through the protocol’s Peg Stability Modules.
3. Purchase on exchange: USDS is available on various crypto exchanges and liquidity pools, where it can be bought like any other token.
4. Bridge between chains: If you already hold USDS on one supported blockchain, you can bridge it to another, such as Arbitrum or Base, using SkyLink to reduce transaction fees.

Once you have USDS, you can store it in any wallet that supports Ethereum or the blockchain network where the token was issued. You can use software wallets for everyday access and hardware wallets for long-term storage.

Transparency and On-Chain Verification

One distinctive feature of USDS is that its backing and system operations can be verified through blockchain analysis, not just via periodic reports from a centralized organization. Because Sky Protocol is governed in a decentralized way, most of USDS’s backing and protocol-level finances can be verified on-chain.

This differs sharply from fiat-backed stablecoins, where reserve verification depends on quarterly reports from the issuer. With USDS, transparency is built into the design: collateral ratios, minting volume, and Peg Stability Module balances can be viewed in real time by anyone with access to blockchain data. For this reason, USDS (and DAI before it) has become one of the best-known examples of transparency in decentralized stablecoins.

USDS Smart Contract Security

Security is critical for any protocol holding hundreds of millions of dollars in collateral. USDS smart contracts inherited and strengthened the original MakerDAO codebase, which has operated for more than five years, and they were thoroughly audited multiple times during the transition from DAI to USDS.

Governance adds another layer of protection: changes to collateral assets, risk parameters, or the system itself can only be made after community discussion and approval by SKY token holders.

This two-level security framework is a major reason USDS and its predecessor have remained long-standing participants in the decentralized stablecoin niche.

When evaluating stablecoins, users should consider audit history and governance alongside collateral and yield data.

USDS Market Data Snapshot

In early August 2026, USDS had become a significant player in DeFi. According to Allium’s stablecoin dataset, its on-chain circulating supply was about $6.37 billion, distributed across four blockchains and mostly on Ethereum.

Another notable metric: Sky Protocol generated $123.79 million in gross protocol revenue in Q1 2026.

Because these figures relate to stablecoin supply and protocol metrics, it’s important to use the latest sources for accurate data.

How USDS Compares to Other Major Stablecoins

USDS can be viewed as a stablecoin similar to USDC and USDT, though it uses a highly decentralized backing mechanism.

Indeed, this decentralization is one reason both USDS and its predecessor DAI remain popular among transparency-focused users.

Why U.S. Users Are Exploring USDS

Interest in USDS among the U.S. crypto community is growing alongside interest in decentralized finance and yield-bearing stablecoins. U.S. users exploring USDS should consider several factors:

• The built-in yield opportunity from Sky Savings Rate, which removes the need to seek other DeFi yield solutions;
• A non-custodial design, meaning users own their tokens without depositing them with a central custodian;
• Cross-chain capabilities via SkyLink, which can benefit people using different blockchains;
• The protocol’s growing real-world asset support, shown through asset-backed lending partnerships and reflecting a maturing ecosystem.

There are also questions about how holding stablecoins and earning yield are treated under U.S. tax rules for digital assets.

USDS Within the Broader DeFi Lending Landscape

USDS actively participates in lending and borrowing within decentralized finance. It serves as liquidity and collateral in DeFi liquidity pools, and because it is pegged to the dollar, it does not carry the same price volatility as other crypto assets.

However, USDS’s usefulness extends beyond Sky Protocol itself. USDS liquidity pools can be found on numerous decentralized exchanges and lending platforms, reflecting broad adoption since the token launched in 2024. This cross-platform usefulness helps sustain USDS’s on-chain circulating supply, estimated at around $6.37 billion in early August 2026.

For users of decentralized lending platforms, a reliable and transparent stablecoin like USDS can be another tool for managing finances through on-chain operations.

The Evolution of Sky Protocol’s Ecosystem

Since rebranding from MakerDAO in August 2024, Sky Protocol has expanded its ecosystem beyond its initial two tokens, DAI and MKR. With sub-ecosystems called Stars, specialized projects can be built on top of the protocol while connecting to USDS as the shared stable asset.

This modular design reflects Sky Protocol’s approach to scaling beyond a single unified system, making it more flexible and capable of handling tasks such as real-world asset lending and cross-chain liquidity.

Conclusion

USDS, also known as the Sky Dollar, is a decentralized USD stablecoin operating within Sky Protocol, the rebranded MakerDAO protocol. The stablecoin is designed to hold a steady value of one US dollar through a combination of on-chain crypto assets and real-world collateral. USDS also offers built-in yield through the Sky Savings Rate.

Despite any naming similarities, USDS has nothing in common with Dogecoin and should not be considered the same cryptocurrency. USDS is a dollar-pegged token used throughout crypto, while Dogecoin is an independent cryptocurrency. With a growing base of collateral and cross-chain accessibility, USDS is becoming an important part of the decentralized finance landscape, including for U.S. users seeking stable, yield-generating tokens.
