Secured Finance Review 2026: Fixed-Rate DeFi Lending

Secured Finance is a DeFi lending protocol built around fixed-rate, fixed-term loans traded through an on-chain order book. DeFi data lists it on Ethereum, Filecoin, Arbitrum, Avalanche and Polygon zkEVM, with a listing date of February 2024 and roughly $246,000 in total value locked.

The homepage now frames it as institutional market infrastructure: term funding, on-chain repo and atomic settlement for tokenized assets. Recent posts mention joining a working group on tokenized Japanese government bond repo, and adding uMINT as eligible collateral. It also links to a USDFC stablecoin app and an SF Yield Vault.

The team page lists a founder and CEO who is a former head of derivatives structuring at HSBC, a head of markets from interest rate derivatives trading, and a smart contract lead who previously worked on a security-token platform. Investors are listed by name, though the project does not give funding amounts.

Secured Finance runs an order book on-chain. Lenders post the rate and term at which they will lend, and borrowers post what they will pay. When orders match, the loan is created at a fixed rate that holds until maturity.

Borrowers post collateral, and the protocol's smart contracts manage it. The homepage describes programmable collateral workflows, including tokenized bonds and money-market assets such as uMINT, used for on-chain repo. Cash and collateral are settled together so neither side is left exposed mid-trade.

The project also describes Itayose, a call-auction style opening mechanism, and auto-rolling, which rolls positions into new terms. It publishes quarterly reports on both. Together, trades at different maturities form a yield curve for digital assets.

The project does not publish a fee schedule on its homepage. Fees for trading, loan settlement and any protocol charges are likely documented in the user guides or shown in the trading interface before an order is placed.

Users also pay network gas fees on whichever chain they use, and these vary by chain and congestion. Check the order confirmation screen for the full cost before signing.

DeFi data lists two audits, but the project does not name the auditors or give findings. The project links to its smart contracts on GitHub, so code can be reviewed publicly. Smart-contract risk remains, as does risk from the collateral assets and the multi-chain deployments.

The project does not state any regulatory licence for the protocol. The institutional positioning suggests a focus on compliance-minded users, but this is not confirmed. Users should check whether tokenized or fixed-income products are permitted where they live. No hacks or incidents are mentioned publicly.

It suits DeFi users who value predictable rates and understand order-book trading, as well as institutions looking at tokenized securities and on-chain repo. Casual users seeking simple variable-rate yield may find other pools easier, especially given the small liquidity here.
