JupUSD is a native, fully collateralized stablecoin developed by the Solana-based decentralized exchange aggregator Jupiter, in partnership with Ethena Labs. It is designed to serve as the primary liquidity and collateral asset within the Jupiter ecosystem. ^{[1] [2]}

Overview

JupUSD was created to function as a core component of the Jupiter protocol on the Solana blockchain. The primary goal is to establish a unified liquidity base for Jupiter's suite of products, including its swap, lending, and perpetual futures markets. By creating its own stablecoin, Jupiter aims to reduce its reliance on external stablecoins like USDC, internalize fee revenue, and retain liquidity within its ecosystem. This strategy follows a broader trend in the decentralized finance (DeFi) sector, where major protocols such as Aave (GHO) and Curve (crvUSD) have launched their own native stablecoins to enhance their platforms' capital efficiency and user experience. ^{[2] [3]}

The project was announced in a market environment characterized by significant growth in the stablecoin sector, with the total market capitalization exceeding $303 billion as of October 2025, an increase of approximately 75% from the previous year. At the time of the announcement, Solana's circulating stablecoin supply was over $15.3 billion, representing about 9.27% of Ethereum's stablecoin market.

The launch also occurred amid increased regulatory attention on stablecoins, notably with the introduction of the "GENIUS Act" in the United States, which aimed to establish a clear regulatory framework for stablecoin issuers. The success of JupUSD is considered dependent on factors such as market confidence, its ability to maintain a stable peg to the US dollar, and the evolving regulatory landscape. ^{[1] [3]}

History

Jupiter officially announced its plans to launch the JupUSD stablecoin on October 8, 2025. The announcement revealed a strategic partnership with Ethena Labs to provide the underlying infrastructure for the stablecoin. In its official communication, Jupiter stated:

"BREAKING: Jupiter is launching its own stablecoin Built in partnership with @ethena_labs , engineered to connect the Jupiverse. $JupUSD , going live in Q4." ^[3]

The projected launch window for JupUSD is scheduled for the fourth quarter of 2025. The launch is contingent upon the successful completion of multiple security audits for its Solana-native mint and redeem contracts. This prerequisite underscores the project's focus on security and stability before its full integration into the Jupiter ecosystem. ^{[1] [2]}

Technology and Mechanism

JupUSD is built on the Solana blockchain and utilizes Ethena Labs' "Stablecoin-as-a-Service" infrastructure. This model allows protocols like Jupiter to create customized stablecoins using Ethena's established framework for collateralization and stability. ^[2]

Collateral Model

JupUSD is designed as a fully collateralized stablecoin with a phased collateral strategy.

• Initial Backing: At its launch, JupUSD will be exclusively backed by USDtb, Ethena's short-term treasury-backed stablecoin. USDtb is itself collateralized by BlackRock's BUIDL tokenized fund, which consists of investments in U.S. treasuries. This structure is intended to provide a stable and low-risk backing for JupUSD in its initial phase. ^{[1] [2]}
• Future Expansion: The development plan includes the future integration of Ethena's flagship synthetic dollar, USDe, as an additional collateral asset. The inclusion of USDe, a delta-neutral stablecoin, is intended to diversify the collateral pool and optimize yield generation for JupUSD holders. The specific timeline for this expansion has not been announced. ^[3]

Ecosystem Integration

JupUSD is engineered for deep integration across the Jupiter platform, aiming to become the central asset for all its services. The planned areas of integration include:

• Serving as collateral for decentralized perpetual futures trading on Jupiter.
• Functioning as the primary stablecoin for Jupiter's trading interfaces.
• Acting as the primary stablecoin for the Jup Mobile application.
• Becoming a major liquidity hub on the Jupiter Lend platform.

This deep integration is designed to create a self-sustaining economic loop within the Jupiter ecosystem. ^[1]

Market Adoption Strategy

To ensure sufficient liquidity and promote immediate adoption upon launch, Jupiter plans to progressively convert approximately $750 million of its USDC holdings from its Liquidity Provider Pool into JupUSD. This strategic conversion is intended to bootstrap the stablecoin's initial supply and establish it as the primary settlement and liquidity unit within the Jupiter ecosystem, effectively replacing USDC in that role over time. This move also marks a significant expansion for Ethena Labs onto the Solana blockchain, aiming to capture a share of its growing stablecoin market. ^{[1] [3]}

Partnerships

The JupUSD project is a collaboration between Jupiter and Ethena Labs, with each entity playing a distinct role.

Jupiter

As the issuer of JupUSD, Jupiter is responsible for its integration and adoption within its ecosystem. At the time of the announcement, Jupiter was the largest decentralized exchange aggregator on Solana, with a 30-day trading volume approaching $20 billion and a Total Value Locked (TVL) of approximately $3.6 billion, according to data from DefiLlama. Its 24-hour revenue was reported to be around $1.2 million. ^{[1] [3]}

Ethena Labs

Ethena Labs serves as the key technology and infrastructure partner for JupUSD. The project leverages Ethena's existing stablecoin framework. Ethena is a significant player in the stablecoin market; its synthetic dollar, USDe, was the third-largest stablecoin by market capitalization as of October 2025. Ethena's dollar-pegged offerings, USDe and USDtb, collectively represented just over 5% of the total stablecoin market at that time. The partnership with Jupiter represents Ethena's first major stablecoin partnership within the Solana ecosystem. ^{[1] [2]}

Key Figures and Commentary

Several key figures from the partner organizations commented on the launch of JupUSD.

Kash Dhanda, the Chief Operating Officer of Jupiter, emphasized the strategic importance of the project, stating that "stablecoins represent a critical component of the platform's mission to serve users globally through decentralized finance rails." ^[1]

Siong Ong, a co-founder of Jupiter, commented on the broader market potential, suggesting that the stablecoin sector is "positioned for significant expansion, with the potential to grow 10 to 100 times from current levels." ^[1]

Guy Young, the founder of Ethena Labs, highlighted the strategic fit of the partnership, describing Jupiter as "an obvious candidate for the first stablecoin partnership within Solana." ^[1]
