Market participants and developers are raising concerns regarding the architectural integrity of Jupiter Lend's vault mechanisms. Critics allege that while the vaults were marketed as "isolated" to prevent risk contagion, recent findings suggest cross-contagion is possible across most assets. The discourse follows reported acknowledgments of shared risk exposure by the protocol team, sparking debate about transparency and safety in Solana DeFi. [Update 1] Kamino Blocks Integration Tensions have escalated as Kamino has reportedly blocked interactions with Jupiter Lend following the controversy over the "isolated" vaults. This action prevents users from depositing liquidity borrowed from Kamino into Jupiter's lending platform, effectively breaking composability between the two major services. The move is a direct response to the allegations that Jupiter's vaults share risk exposure, with Kamino moving to protect its users from potential cross-contagion risks.
