By depositing their SOL, users are able to borrow, for a one time fee of 0.5%, the USH stablecoin interest free at a minimum collateral ratio of 110%.

USH is always redeemable for its underlying SOL, though a dynamic fee ensures this process happens only as often as required to maintain peg.

Hedge’s liquidation design involves a stability pool where users can preemptively deposit USH to earn HDG tokens as well as instantly liquidate risky positions once they fall below the collateral ratio. This design enables faster liquidations, keeping the system healthy as well as protects USH from large price fluctuation in volatile markets.
