The recent shock from the KelpDAO rsETH hack is no longer limited to EVM-based ecosystems. A wider Solana DeFi outflow is now becoming visible, with stress showing up in key USDC lending markets on Kamino, one of Solana’s top DeFi platforms.
Data from Kamino-linked markets shows that users have been pulling or repositioning capital at a fast pace. That movement has caused deposit APY and utilization rates to climb sharply across several USDC pools. In lending markets, rising utilization usually signals that available liquidity is drying up as more funds are borrowed or withdrawn.
The clearest sign of the Solana DeFi outflow is visible in Kamino’s Prime Market USDC Reserve. The reserve, which holds around $178 million in scale, has reached 100% utilization. That means there is currently no available liquidity left in that pool.
This kind of condition often creates a tense environment for DeFi users. Lenders may be attracted by higher yields, but borrowers can face rising costs and reduced flexibility. At the same time, full utilization can be read as a warning that market participants are moving quickly in response to risk.
Other Kamino-linked vaults are also flashing similar signals. The Staekhouse USDC Vault and the RockawayX RWA USDC vault both recorded utilization rates above 95%. When multiple vaults move to those levels at once, it suggests the pressure is broad rather than isolated.
The spread of this Solana DeFi outflow shows how quickly market fear can jump across chains. What started as a security event tied to KelpDAO rsETH has now affected sentiment beyond Ethereum-aligned environments. Capital in DeFi tends to move fast, especially when users feel that liquidity risk may rise.
For Solana, this moment is important because it highlights how connected cross-chain confidence has become. Even if the original issue happened elsewhere, liquidity conditions on Solana can still tighten as traders and lenders react defensively.
The main question now is whether fresh capital will return to these USDC markets and stabilize utilization, or whether risk-off behavior will continue in the near term.
