Tangent Finance Review 2026: USG Lending on Ethereum

Tangent Finance is a decentralized lending protocol on Ethereum that issues USG, a crypto-backed stablecoin. Users deposit yield-bearing collateral, such as Curve and Convex LP positions, and borrow USG against it.

The protocol describes itself as a stablecoin system focused on capital efficiency, with an interest-free option on dedicated markets. The app lists many markets, including stablecoin pairs and a few non-stablecoin ones such as msETH/WETH, cbBTC/WBTC and CVX/ETH, and has sections for savings, earn, claim, swap and a DAO.

It is very new. DefiLlama lists it from late May 2026, shows about $3.7 million in TVL, and reports a 6.6% drop over seven days. It has no token listed, though the app mentions an airdrop and points.

Tangent is a lending protocol. A user deposits collateral into a market and borrows USG against it. Many of the listed markets use pairs of stablecoins or similar assets, and the protocol describes the collateral as yield-bearing, such as Curve and Convex LP positions.

USG is a crypto-backed stablecoin, meaning its value is supported by assets locked in the protocol rather than by a bank balance. To keep USG near one dollar, Tangent uses dynamic interest rates that change the cost of borrowing, plus Curve V2 peg keepers that act in Curve pools. Savings through sUSG appears to let holders earn yield on USG.

The homepage names three market types, HEC, LEC and FIR, and refers to an interest-free option on dedicated markets. The project does not define these terms, so newcomers should read the documentation before using them.

Fees are not fully published publicly. The homepage shows a Borrow APY per market and a vAPR column, and says some dedicated markets have an interest-free option. The values appear as zero in the page text, so users should check each market in the app before borrowing.

Borrowers also pay Ethereum gas fees and should account for swap costs on any Curve pools they use. Any protocol or liquidation fees are not stated publicly.

DefiLlama lists two audits for Tangent, but the project does not name the auditors, the scope or the findings. No incidents are mentioned publicly, though the protocol is only weeks old by DefiLlama's listing date. Users should read the audit reports and the documentation themselves.

Risks include smart-contract bugs, liquidation of collateral, depegging of USG or collateral assets, and dependence on Curve pools and peg keepers. Using LP positions as collateral adds exposure to the underlying pools. Borrowing is self-custodial through a wallet, but the project does not describe admin keys or governance controls. This is not financial advice.

Tangent is for experienced DeFi users who hold yield-bearing stablecoin or LP collateral on Ethereum and want to borrow USG against it. It is a poor fit for beginners, anyone who wants a long track record, or users who cannot monitor liquidation risk.
