Spark Prime is built for institutional crypto borrowers. It enables capital-efficient, over-collateralized lending by allowing positions to be margined across DeFi protocols, CEXs, and qualified custodians within a governance-defined risk framework. This infrastructure supports a framework for yield-bearing USDS deployments, sourcing returns from institutional delta-neutral strategies executed within Spark Prime, while maintaining transparency and risk controls. DeFi lending markets like SparkLend have demonstrated resilience in adverse market conditions, thanks to their over-collateralized lending model. However, this lending method is extremely capital-intensive. Borrowers need to post excessive collateral to ensure they won’t be liquidated. Also, positions in DeFi lending markets are unaware of collateral that may be held at external locations, such as centralized exchanges. A naive approach to circumventing these capital inefficiencies is to engage in unsecured lending, which can yield higher returns but requires significant trust in the borrowing entity. Lending unsecured is easy when things are going well, but DeFi needs to be resilient even in hostile conditions. The 2022 collapse proved that lending unsecured can go very wrong. Spark Prime addresses this gap by combining protocol-allocated liquidity governed by Spark’s risk frameworks with Arkis’ margin and execution platform. Spark Prime’s ApproachSpark Prime combines the best of both worlds by providing the capital efficiency of unsecured lending structures while maintaining collateralization controls within defined execution environments like the brokerage's walled garden. Spark Prime is designed to support new institutional lending workflows, including:More resilient delta-neutral lending supported by over-collateralized positions.Enhanced capital efficiency relative to traditional DeFi lending markets.Improved DeFi transparency. Opaque funds can lead to hidden risks, but with Spark Prime, positions are visible in real time through protocol-level data and transparency mechanisms. Spark Prime leverages protocol-allocated liquidity governed by Spark’s risk management frameworks. This draws on the protocol’s long history and experience operating large-scale, resilient DeFi systems. How Spark Prime worksArkis’ margin technology enables borrowers to distribute collateral custody across smart contracts, qualified custodians, and centralized trading venues via a direct market access (DMA) setup. Liquidity allocation and risk parameters are defined through Spark’s governance frameworks and enforced by the Arkis platform. Margining is supported across:CeFiBinanceBybitOKXHyperliquidDeFiPendleCurve Who is Spark Prime forHedge funds are one of the largest borrowers in DeFi, accounting for the majority of market activity. Spark Prime enables these strategies by combining on-chain transparency with access to CeFi liquidity and execution venues through the Arkis platform. Use Cases1. Basis Trading with cross margin across CEX/DEX venues Spark Prime enables funds to collateralize positions across governance-approved venues. Funds that want to take advantage of yield farms in DeFi can now take long exposure in DeFi or qualified custody, and short perpetual futures on CEXs. Arkis’ risk engine, integrated into Spark Prime, recognizes the long-spot vs. short-perp hedge across multiple venues in CeFi and DeFi, so margin is set on net risk, not gross notional. This lowers initial/maintenance margin and unlocks higher effective leverage than siloed venues. 2. Qualified Custodian Support Spark Prime supports collateralization of positions held with qualified custodians through defined tri-party enforcement structures. Institutions maintain compliance with internal mandates while gaining real-time access to credit in DeFi and CeFi. 3. Portfolio Margin with Multi-Collateral Diversification Spark Prime allows borrowers to post multiple, low-correlated assets, like LSTs, LP tokens, RWAs, and stables. Because these assets exhibit diverse risk profiles and cross-asset hedging effects, the margin engine assigns reduced risk weights at the portfolio level rather than penalizing each asset individually. This diversification improves the account's health score, enabling greater borrowing power, lower liquidation risk, and optimized margin utilization without adding net directional exposure. 4. Less Volatile Borrowing Costs Borrow rates using interest rate models based on the expected yield of the posted collateral, not just on pool utilization. This creates a target spread: borrowers always guarantee a minimum yield-to-borrow cost gap. As a result, looping or hedging strategies gain predictable funding and can scale with confidence. Borrowers still leverage low-cost collateral and borrow stables or crypto in real time. Rate spikes become less likely because the model reduces dependence on volatile utilization. This improves ROE and reduces tail risk from rapid cost escalation. This is ideal for institutional strategies that require risk-budgeted lending and repeatable outcomes. Partners & AUMSpark Prime is launching with the biggest institutional participants in the space. Initial launch partners include:Edge Capital ($600 million AUM)M1 ($180 million AUM)Hardcore Labs ($100 million AUM)An allocation of $15 million has been made, but this list is just a start. The total addressable market for delta-neutral strategies in crypto is in the tens of billions, and Spark Prime is well-positioned to capture a significant share. RoadmapSpark Prime has started small to ensure all components operate reliably and safely, with a clear path toward scaling: 1. Contract Upgrades and Market multi-party approval The process for upgrading the code and adjusting market risk parameters will shift to a multi-party approval process, involving relevant contributors and stakeholders across Arkis, Spark, and Sky ecosystem. 2. Off-exchange Settlement Off-exchange settlement is the process of holding collateral assets with qualified custodians rather than holding them directly on the exchange. It has become an industry standard to protect against exchange hacks. 3. Liquidation Fallback To provide stronger assurances of solvency, a backup liquidation method is being included to take over in the event of the core margin engine's failure. 4. High-Yield Vault A governance-defined USDS deployment framework is expected to launch, providing junior tranche exposure to Spark Prime. It is expected that these changes will be progressively added in Q2/Q3 of 2026. Each upgrade reduces the protocol's risk and allows Spark to progressively increase its exposure accordingly. Spark Prime represents an evolution in how DeFi and CeFi infrastructure can interoperate to support institutional lending protocols. Building on Spark’s governance-defined risk frameworks and Arkis’ execution technology, Spark is poised to raise the bar on CeDeFi lending.
