Jupiter, the Solana-based decentralized exchange aggregator, announced on Oct. 8, that it will launch its own native stablecoin, JupUSD, in partnership with Ethena Labs.



The new token will serve as the core liquidity and collateral asset across the entire Jupiter ecosystem, including its perpetual futures, lending, and spot trading platforms. <a href="https://x.com/JupiterExchange/status/1975929208049463384">According</a> to Jupiter, JupUSD is slated to go live in the fourth quarter of 2025, pending multiple security audits of its Solana-native mint-and-redeem contracts.



JupUSD will be initially backed 100% by USDtb, a stablecoin nearly fully collateralized by BlackRock’s BUIDL fund, before incorporating USDe, Ethena’s delta-neutral stablecoin, to optimize yield for holders. The partnership extends Ethena’s Stablecoin-as-a-Service model, which allows protocols to create bespoke digital dollars using its infrastructure.



Ethena, which has issued over $16 billion in stablecoins to date, <a href="https://x.com/ethena_labs/status/1975924462152495602">positions</a> JupUSD alongside other ecosystem-native assets such as Frax’s USDe integrations and MegaETH’s USDm.



The collaboration mimics a growing trend among major DeFi protocols toward self-issued stablecoins to retain liquidity and fee revenue internally — a path also taken by Aave’s GHO and Curve’s crvUSD.&nbsp;

Ethena

Jupiter launches JupUSD stablecoin with Ethena Labs on Solana

YZi Labs announced that it has expanded its holding in Ethena Labs, the protocol behind USDe, the third-largest dollar-denominated crypto asset. According to a release <a href="https://x.com/yzilabs/status/1969025323582071159">posted</a> by YZi, the investment signals continued backing for Ethena’s next growth phase, which includes deeper adoption of USDe across centralized exchanges and DeFi platforms, expansion on BNB Chain, and the development of new products such as USDtb, a fiat-backed stablecoin, and Converge, an institutional settlement layer.



YZi Labs, formerly Binance Labs, first invested in Ethena through its Season 6 Incubation Program in February 2024, before USDe’s public launch. Ethena’s model is built on delta-neutral hedging, designed to stabilize its synthetic dollar while generating sustainable yield without reliance on traditional banks.



Since then, USDe has grown rapidly to more than $13 billion in supply, crossing the $10 billion milestone faster than any other stablecoin. Ethena’s total value locked (TVL) now exceeds $13 billion, with integrations spanning leading DeFi applications and centralized exchanges.



The renewed commitment comes as Ethena strengthens its presence on BNB Chain following an April 2025 deployment, introducing money markets and new protocol partnerships. Upcoming products like USDtb aim for regulatory compliance, while Converge, developed with partners including Securitize and BlackRock collaborators, seeks to bring real-world assets onchain.

YZi Labs expands Ethena Labs stake as USDe adoption grows

The Ethena Foundation said Monday that parameters required to activate its ENA fee switch have now been met, with final implementation details under review by the protocol’s Risk Committee before a governance vote can proceed.



The fee switch, first <a href="https://gov.ethenafoundation.com/t/wintermute-governance-proposal-for-ena-fee-switch/306">proposed</a> by trading firm Wintermute in November 2024, is <a href="https://x.com/EthenaFndtn/status/1967592364744290455">designed</a> to direct a portion of Ethena protocol revenue to ENA holders who stake their tokens. The Risk Committee previously outlined “success metrics” such as supply growth of USDe, Ethena’s synthetic dollar stablecoin, and cumulative protocol revenue milestones.



Governance forum updates <a href="https://gov.ethenafoundation.com/t/ena-fee-switch-parameters/396">suggest</a> those benchmarks — including a USDe supply surpassing $6 billion and protocol revenue near or above $250 million — have been reached, though the committee has not yet confirmed each threshold publicly.



The next phase involves defining how revenues would be shared with stakers and what safeguards will apply. Governance documents have <a href="https://gov.ethenafoundation.com/t/ena-fee-switch-parameters/396">referenced</a> measures such as comparing yields to market benchmarks and monitoring risk metrics, but the specifics of reserve management and allocation remain under discussion.



If approved by ENA holders through a formal vote, the change would align incentives more closely with protocol growth by granting direct exposure to revenue. The Risk Committee said details will be published before the proposal is put to a vote.

Ethena Foundation prepares ENA fee switch for token holder vote

Macauley Peterson

Cap Labs’ new stablecoin cUSD has seen rapid adoption since launch, climbing to $67.85 million in circulation over the past week, <a href="https://defillama.com/stablecoin/cap-cusd">according</a> to DefiLlama.&nbsp;



Etherscan <a href="https://etherscan.io/token/0xcccc62962d17b8914c62d74ffb843d73b2a3cccc">shows</a> 2,735 holders of the token to date. The jump signals strong demand for Cap’s yield-layered digital dollar model, which combines regulated reserve assets with EigenLayer-powered credit underwriting.



Built atop the newly launched Cap Stablecoin Network (CSN), cUSD is designed as a 1:1 redeemable stablecoin backed by assets like <a href="https://blockworks.co/tag/paypal">PayPal’s</a> <a href="https://blockworks.co/price/pyusd">PYUSD</a>, <a href="https://blockworks.co/tag/blackrock">BlackRock</a>-managed <a href="https://blockworks.co/news/buidl-collateral-tokenization">BUIDL</a>, and <a href="https://blockworks.co/tag/franklin-templeton">Franklin Templeton’s</a> BENJI. The yield-bearing version stcUSD — minted by staking cUSD — is enabled by a three-party system of lenders, operators, and restakers.



Cap’s core innovation lies in its structure: operators borrow stablecoins to deploy yield strategies, restakers underwrite the operator’s credit risk, and lenders (stcUSD holders) earn a floating yield, currently around 12%, depending on market demand and operator performance. While restaker collateral provides protection against operator default, stcUSD holders are still exposed to fluctuating yield dynamics.



<figure class="wp-block-image"><img decoding="async" src="https://lh7-rt.googleusercontent.com/docsz/AD_4nXcu_7EBXZi3VItlG_gUlP9ZdT_spy2QXjOEzbUMHu7GkZFHRrKyJZ9-tlygRXK5q_omNcVAeG6WuoQ6iSAgmzzZFOSBYsP0chFvaZY1O5vP7YJeK2iehw-MHotrGOt4ZVsJb5OyEA?key=1HSKtor9sNS05yY8kpZnCg" alt=""/><figcaption class="wp-element-caption">cUSD’s impressive growth; Source: <a href="https://defillama.com/stablecoin/cap-cusd">DefiLlama</a></figcaption></figure>



Unlike many past stablecoin launches, Cap’s model is carefully tuned to comply with the <a href="https://blockworks.co/tag/genius-act">GENIUS Act</a>, the sweeping US stablecoin legislation that prohibits interest-bearing payment tokens. Speaking at the Stablecoin Summit in Cannes <a href="https://youtu.be/fxd5wXtAaC8?si=45kDRI1mmi8Zt56U">in June</a>, Cap Labs founder Benjamin Lens was blunt:



“They said no yield, and it’s pretty clear — there’s no way around it. They do not want stablecoins giving yield to retail investors,” Lens said.



Thus, stcUSD is a separate <a href="https://blockworks.co/tag/erc-4626">ERC-4626</a> vault token, which users can mint by staking cUSD. The yield is generated through a marketplace of borrowing and restaking, not directly from Cap Labs.



“Genius Act covers companies that are generating yield on behalf of users and giving them to the users,” Lens said in Cannes, whereas Cap is “an immutable open protocol like <a href="https://blockworks.co/tag/ethereum">Ethereum</a>, like Bitcoin.”



Combined with the fact that the percentage of any one stablecoin backing cUSD is limited to 40%, Lens thinks they have a compliant mechanism. “This is the standard that we&#8217;ve agreed to with Templeton and BlackRock for our integration with them,” Lens told Blockworks, noting it’s the same arrangement that UStB (from Ethena) made in partnership with BlackRock.



<h2 class="wp-block-heading">Restaking evolution</h2>



Cap’s design aligns with a trend emerging with restaking platforms such as <a href="https://blockworks.co/tag/eigenlayer">EigenLayer</a> and Symbiotic: the financialization of Actively Validated Services (AVSs). Traditionally, AVSs on EigenLayer offered infrastructure services — like oracles or bridges — with risk limited to uptime or correctness. But a new wave of AVSs is using EigenLayer to underwrite financial guarantees.



Cap is one example highlighted by EigenLayer founder Sreeram Kannan. “A staker can stake and promise that an operator [like Susquehanna] is going to make a 10% APR,” Kannan told Blockworks. “You can underwrite financial risk using EigenLayer, which is a very new kind of risk, which requires much, much more active curation and monitoring,” he said.



What makes this possible is EigenLayer’s recent rollout of a new feature, complementary to slashing, which <a href="https://blockworks.co/news/restaking-use-cases-reframed">went live in April</a>.&nbsp;



While slashing enables restakers to be penalized for backing underperforming operators, <a href="https://docs.eigencloud.xyz/products/eigenlayer/concepts/slashing/redistribution">redistribution</a>, launched in late July, allows slashed funds to be redirected back to the impacted AVS — such as Cap’s lending vault — rather than burned.



That change turns EigenLayer into a programmable risk distribution layer, capable of enforcing structured finance contracts entirely onchain.



“With financial AVSs, slashing is the core logic,” Kannan said. “A liquidation is an example — if the hurdle rate is not met — slash and move the money out.” That’s easier than slashing some infrastructure AVSs like a ZK or TEE coprocessor, where it’s harder to adequately express the slashing logic onchain, he added.



The early growth of cUSD “highlights demand for stable, compliant dollars backed by decentralized risk management,” according Misha Putiatin, co-founder of Symbiotic, which also provided infrastructure underlying Cap’s real-time credit risk coverage.



“This marks an important step toward programmable DeFi where anyone can transparently launch, underwrite, and manage new financial primitives,” Putiatin told Blockworks.



According to a research note from Serenity Research and Catalysis <a href="https://serenityresearch.substack.com/p/serenity-premium-cap-money-and-cusd">published</a> Sunday, Cap’s model resembles a CDS-like structure: Restakers sign off-chain legal agreements to cover operator defaults, post collateral onchain, and are liquidated if their guarantee fails. Cap currently lists market makers like Fasanara, GSR, and Amber as operators, with Gauntlet and <a href="https://blockworks.co/tag/symbiotic">Symbiotic</a> restakers providing credit protection.



Cap Labs’ operating company, which handles smart contracts, social media and frontend, is based in Panama, Lens said.



“There are currently no plans to geofence the US. Since we&#8217;re functionally an autonomous, overcollateralized lending market, we&#8217;re taking a similar precedent to <a href="https://blockworks.co/tag/aave">Aave</a> and <a href="https://blockworks.co/analytics/morpho">Morpho</a>,” he said.



As Cap’s model gains traction, it could preview a broader shift in the restaking ecosystem: from securing infrastructure to enabling onchain credit underwriting, with slashing and redistribution forming the enforcement rails for next-gen financial AVSs.
