Neptune Finance Review 2026: Injective Lending Market

Neptune Finance is a lending and borrowing protocol on Injective. DefiLlama describes it as Injective's first and largest peer-to-peer lending market and lists about 3.65 million dollars in TVL. It has been listed since February 2024.

The homepage targets three groups: traders who want collateral that earns yield, developers who want APIs and flash loans, and institutions or DAOs managing treasuries. Supported assets shown include ATOM, SOL, INJ, TIA, USDC, USDT and WETH.

The protocol has its own token, NEPT, used for staking, governance weight and flash loan access. Several features are listed as upcoming, including insured deposits, RWA assets, accumulator vaults and an earn proxy.

Neptune is a money market. Lenders deposit assets into a pool and receive nTokens that represent their claim and earn interest. Borrowers post collateral and take loans from the pool, paying interest that flows to lenders.

The distinguishing feature is its rate model. Rather than a fixed curve, the homepage describes a PID Controller that moves rates toward a target utilisation, shown as 80 percent. When borrowing is below target, rates fall to attract borrowers. When utilisation is high, rates rise. DefiLlama calls it peer-to-peer, but the pool model is what the homepage describes.

If a borrower's collateral value falls too far, the position can be liquidated. Neptune lists dynamic liquidation premiums and partial liquidations, so only part of a position may be closed. Prices come from oracle providers, which makes oracle quality important to safety.

Neptune's homepage says there are no sign-ups, lock-ups or withdrawal fees. It does not publish borrow rates, supply rates, protocol fee cuts, liquidation penalties or flash loan fees in the text we reviewed.

Rates are variable and shown in the app's rates section, with 1-year, 90-day and 30-day views. Network gas costs on Injective also apply. Check live rates and the docs before opening a position.

The homepage states an audit by Oak Security and says the team works with third-party security experts. DefiLlama, however, lists zero audits for the project. Treat the audit status as something to verify yourself through the official audit reports and docs.

Lending protocols carry smart-contract risk, oracle risk and liquidation risk. Borrowers can lose collateral if prices drop quickly, and lenders can be affected by bad debt. Insured deposits are marked upcoming, so deposits should not be assumed insured. No incidents are mentioned publicly, and none are claimed here. This is not financial advice.

Neptune is aimed at Injective users who want to earn yield on idle assets, borrow against collateral, or build bots and vaults with flash loans and APIs. It may also suit DAOs looking for treasury yield. People unfamiliar with liquidation risk should read the docs and start small.
