Analyzing Jup Lend vs. Kamino

Over the past several days, the exchange between Kamino and Jupiter has escalated from healthy competition to a clear public dispute. The events started on Nov. 27, when Jup Lend introduced a refinancing tool on its frontend to migrate looping positions from Kamino Multiply directly into Jup Lend with a single click. The refinance operation initiated an atomic transaction involving four steps:

1. Repay outstanding debt on Kamino.
2. Withdraw the associated collateral.
3. Transfer these assets to Jupiter Lend.
4. Recreate the position inside Jupiter Lend, maintaining the same loan amount and collateral ratio.

On Dec. 2, Kamino updated its smart contracts to block Jupiter’s program, preventing one-click refinancing. Both the Jupiter and Fluid teams (Jup Lend uses Fluid in the backend) framed the move as anti-competitive and against “open-finance principles.”

On Dec. 6, Kamino’s co-founder publicly explained the rationale for blocking Jup Lend’s migration tool, noting that Jupiter had repeatedly suggested that borrowers’ collateral is isolated, implying it is neither rehypothecated nor exposed to cross-contamination risk. However, this claim was not true, with even Fluid’s co-founder acknowledging rehypothecation within Jup Lend.

​Notably, Kamino never prevented users from repaying their loans manually and withdrawing their capital to Jup Lend. Whether against open-finance principles or not, the move to block the refinancing program was fundamentally a business decision, much like Jup Lend’s decision not to open-source its code (though it has plans to do so). In this regard, it’s interesting to analyze the competitive dynamics between both money markets over the past few months.

Since its launch in late August, Jup Lend has grown to $1.6 billion in deposits and $610 million in borrows. The chart below shows that Kamino’s deposits and borrows have decreased by $1.3 billion (-28%) and $460 million (-26%), respectively, during the same period.

The top five assets by deposit growth since Jup Lend’s launch are USDC ($485 million), JLP ($225 million), SOL ($206 million), syrupUSDC ($174 million), and jupSOL ($85 million). During the same period, Kamino has seen sizable outflows for all of these assets, except syrupUSDC. However, even for syrupUSDC, Jup Lend still attracted roughly 3x more inflows.

Kamino’s growth over the past few months has come from assets not yet supported by Jup Lend. In particular, stablecoin inflows in Q4 have been driven by PYUSD ($42 million) and Phantom’s CASH ($125 million). Kamino has also been proactive in onboarding DATCO LSTs; most notably dfdvSOL and more recently fwdSOL.

Kamino’s PRIME integration stands out as a catalyst that can bring net new inflows into the money market. PRIME gives users exposure to a regulated credit pool backed by US real estate loans originated and serviced through Figure. This integration effectively gives access to a source of yield uncorrelated from crypto markets that may attract more institutional borrowers.

Wrapping up, Kamino and Jup Lend are obviously competitors, and competition is healthy as it drives innovation and ultimately benefits users. That said, as Solana Foundation’s Lily Liu noted, instead of fighting with each other, Kamino and Jupiter should focus on growing the pie and capturing market share from other chains and TradFi thereafter. Combined, both money markets still account for less than 10% of Aave’s deposits, and without initiatives like the PRIME integration, it will be impossible to close this gap.
