Hedge is a Solana lending protocol that enables the minting of stablecoin USH. Users can take out 0% interest loans for a one-time fee by depositing collateral for USH. To avoid liquidation, users must maintain a collateral-to-debt ratio of at least 110%. When an undercollateralized vault is liquidated, users who have deposited USH in a stability pool are rewarded with discounted collateral. USH is always redeemable at its underlying value, but a fee is charged to minimize frequent impacts on the protocol.
