Flux Finance — Decentralized Stablecoin Lending Protocol

Everything you need to know about Flux Finance, how it works, and how to get started with DeFi lending backed by tokenized US Treasuries.

Flux Finance is a decentralized lending protocol that enables users to lend stablecoins (USDC, USDT, DAI, FRAX) and earn yield backed by tokenized US Treasuries. Borrowers provide OUSG — a tokenized US Treasury product from Ondo Finance — as collateral to access stablecoin liquidity. The protocol is governed by ONDO token holders through the Ondo DAO.

To earn yield on Flux Finance, connect your wallet and supply stablecoins such as USDC, USDT, or DAI to the protocol. In return you receive fTokens (fUSDC, fDAI, etc.) that automatically accrue interest over time. You can redeem your fTokens at any time to reclaim your stablecoins plus earned interest.

Flux Finance accepts only OUSG as collateral. OUSG is a tokenized US Treasury token from Ondo Finance that primarily invests in the BlackRock USD Institutional Digital Liquidity Fund (BUIDL) and BlackRock's FedFund (TFDXX). This makes Flux Finance uniquely safe compared to protocols using volatile crypto collateral.

Flux Finance is a fork of Compound v2, one of the most battle-tested DeFi protocols in existence since 2019. The codebase has been audited by Trail of Bits, OpenZeppelin, and Certora. Permission-related changes were audited separately by code4rena. An active $550,000 bug bounty on Immunefi adds an additional layer of security for the protocol.

You can access Flux Finance through a variety of wallets and institutional platforms including MetaMask, Coinbase Wallet, Fireblocks, Ledger hardware wallets, and Gnosis Safe multisig. Flux Finance fTokens can also be traded on CoWSwap via the Seasolver integration, and used as collateral backing in Reserve Protocol's RTokens.
