Tangent Finance is a live Ethereum DeFi protocol that issues USG, an over-collateralized CDP stablecoin fully backed by productive collaterals such as boosted Curve LP tokens (and soon Pendle LPs & PTs). Users can open leveraged positions against yield-bearing assets, borrow USG, and keep most of the underlying yield. The protocol also features sUSG, a savings product that distributes endogenous protocol revenue. Everything is designed for capital efficiency and self-sustainability without relying on external token emissions.
