NAVI Protocol has launched NAVI Prime on Sui, a lending platform aimed at institutional investors that uses isolated risk vaults and curator-run liquidity markets instead of a single shared pool. The protocol said the rollout was its biggest service overhaul in three years, followed more than four months of development and included more than three security audits. By letting specialist curators create separate markets for specific assets or strategies, NAVI Prime lets each pool set its own terms and risk profile, a structure intended to give professional users tighter control over exposure and to limit contagion between markets. The product arrives as DeFi lending platforms try to attract institutional capital while addressing regulatory, operational and risk-management concerns. NAVI Protocol said it has reached a peak total value locked of $1 billion since launching in 2023, served more than 1.1 million cumulative users and at one point held about 40% of Sui's DeFi market. Separate DefiLlama data in the existing topic showed about $124.6 million in total value locked and roughly $65.8 million in active loans as of Aug. 17. If the model gains traction, it could influence how other protocols structure lending services for professional capital.
