Kamino Lend V2 marks a new milestone for lending on Solana: a modular infrastructure, isolated markets, automated vaults, and an improved user experience. A deep dive into an architecture designed to make Kamino the reference on-chain credit layer on Solana.
In just two years, Kamino has become the most used lending application on Solana. With over 4 billion dollars in cumulative TVL across its products and zero bad debt recorded since its inception, the protocol has established itself as a benchmark in security and performance within Solana's DeFi ecosystem.
Kamino Lend V1 was based on a traditional model of overcollateralized lending markets. But with the explosion of supported assets, the rise of LSTs, and the emergence of more complex use cases (RWAs, institutional funds, structured yield products), this monolithic architecture reached its limits.
It is in this context that Kamino announced its V2 in 2024, with a clear ambition: to provide a modular, scalable, and interoperable lending layer for Solana’s next growth phase. The core protocol remains unchanged as the V1 codebase still serves as the foundation, but the architecture has been entirely redesigned around two main components:
Kamino thus aims to meet a dual challenge: enabling the rapid creation of new markets (with custom parameters) while offering a simple and unified UX for users.
Kamino V2 is built on a modular architecture designed to expand the use cases of on-chain lending. This new version is structured around two complementary layers: the Market Layer and the Vault Layer. It also includes major improvements in execution, risk management, and user experience.
Kamino V2's Market Layer enables the permissionless creation of lending markets with fully customizable parameters. Each market can be configured with different assets, specific risk rules, dedicated oracles, individualized borrowing limits, and adjustable interest rate curves.
This modular model offers great flexibility to tailor credit infrastructure to the nature of the underlying assets: stablecoins, LSTs, RWAs, memecoins, or even illiquid assets. It becomes possible to create custom lending environments with specific rules for each collateral and borrowable asset combination.
Key features of the Market Layer include:
This modularity also meets the needs of institutional players and facilitates the onboarding of new asset classes such as RWAs.
The growing diversity of markets makes manual yield optimization increasingly difficult for users. Kamino V2's Vault Layer introduces automated lending vaults, designed as “earn account” type products adjusted according to different investor risk profiles.
Each vault aggregates liquidity across multiple V2 markets based on a mandate defined by a curator (external partner or Risk Council member). Allocations are rebalanced dynamically to maximize returns while adhering to preset risk parameters.
Several profiles are available at launch:
Kamino has already onboarded several partners to manage these vaults, including Steakhouse, Re7 Labs, Allez Labs, and MEV Capital. More specialized profiles (RWA, LST-only, thematic) are in development.
Kamino V2’s modular architecture enables the deployment of a broader range of credit products on Solana, combining automation, leverage, and customization. Some of these products already existed in V1 but now benefit from significant upgrades, while others are entirely new.
One of Kamino’s flagship products is Multiply, an automated leverage loop strategy (e.g. mSOL/SOL, wBTC/SOL) integrated directly into the interface. With over 1 billion dollars deployed through this product, Multiply has become a cornerstone of the protocol.
Kamino V2 expands on this concept with a new product: Spot Leverage. It is a simple and efficient leverage tool for users seeking long-term exposure with a 2x to 4x multiple, without relying on perpetual futures.
Advantages include:
This positioning aims to attract a broader user base, especially SOL, BTC, or memecoin holders looking for more aggressive exposure over longer timeframes with enhanced safety.
As part of the Kamino V2 launch, ten new markets were introduced to power Multiply and leverage products, alongside over 285,000 dollars in monthly incentives:
These markets are directly compatible with Multiply and allow users to create leveraged loops directly from the interface, while also receiving associated rewards. Any position opened through these markets via Multiply or Earn Vaults is automatically eligible for incentives.
Another strategic addition is the upcoming Orderbook Lending system, where users will be able to place lending or borrowing offers at defined interest rates, similar to an order book.
This approach allows for more precise user intent expression and could provide greater granularity in interest rate formation on Solana. This system is still under development but aligns with the protocol’s modular logic.
Kamino also aims to become the native credit layer for real-world assets (RWAs) on Solana. Thanks to the flexibility of V2 markets, the protocol can integrate assets like syrupUSDC (from Maple Finance), with tailored risk rules and adapted leverage products.
The ecosystem has already seen the launch of RWA markets in collaboration with:
This momentum opens the door to Kamino’s institutional expansion, with the deployment of KYC-enabled markets, fixed yield products, and custom vaults designed for asset managers.
The launch of Kamino V2 was met with immediate adoption, confirming the relevance of its modular architecture and the strength of its infrastructure. Less than three weeks after going live on mainnet, V2 markets have already surpassed 200 million dollars in deposits, with over 80 million dollars in active borrowings.
In total, the protocol reports:
Ten new markets were launched as part of V2, each structured as an isolated market with its own risk, liquidity, and incentive parameters. These markets operate on the same codebase as V1, ensuring full compatibility with the existing ecosystem and a high level of security: 14 external audits and formal verification via Certora.
Two examples particularly illustrate the effectiveness of Kamino’s model:
These examples highlight how the Multiply - Market Layer - Earn Vaults triptych acts as a strong growth engine for both Kamino and the broader Solana ecosystem.
With Kamino V2, the protocol evolves from a high-performing lending platform into a true infrastructure layer for on-chain credit. It is designed to support the growing diversity of assets on Solana and to enable the development of new financial products at the intersection of DeFi and TradFi.
Kamino now positions itself as an abstraction layer for all credit-related use cases on-chain: isolated markets, automated vaults, leveraged products, yield-bearing stablecoins, RWAs, and more. This repositioning makes Kamino a core component of Solana's on-chain economy.
Beyond lending, Kamino also becomes a strategic tool for liquidity bootstrapping on Solana. The Marinade market showcases how linking an isolated market to Multiply loops encourages mSOL issuance while offering users automated leveraged strategies. This model aligns the interests of partner protocols, users, and the Kamino infrastructure itself.
The Maple Finance example goes even further, allowing a protocol external to Solana to integrate seamlessly into the ecosystem. In just a few days, more than 90% of syrupUSDC’s supply has already been integrated into Kamino’s ecosystem (Multiply, Earn, Market). This ability to quickly onboard new assets also illustrates Kamino’s potential to become a hub for RWA integration on Solana.
At a time when the Solana ecosystem is transitioning away from the peak of the memecoin cycle, finding new, robust narratives is critical. The convergence between DeFi and TradFi, led by RWAs, could well be the next major trend, with Kamino already positioning itself as a key catalyst.
Finally, Kamino currently enjoys a clear technical and strategic edge over its competitors. While other lending platforms remain constrained by monolithic architectures, Kamino offers a flexible, interoperable, and extensible infrastructure-with no friction or learning curve for end users.
