Questions about
borrowing
What is UNIT?
UNIT is Ducat’s bitcoin-backed stablecoin, designed to track the US dollar. Borrowers lock BTC collateral to mint UNIT.
How UNIT worksHow much can I borrow?
Your borrowing capacity depends on your BTC collateral and the vault’s collateral ratio. Review the available amount, fees, and liquidation price in the app before confirming.
Review borrowing termsWhen can I get my bitcoin back?
Repay the outstanding debt, then redeem the collateral through a Bitcoin transaction. If your vault reaches its liquidation threshold first, its collateral can be liquidated.

The strategy is in development. It proposes sharing minting fees, managed liquidation income, and managed liquidity-pool fees with depositors, with payouts in BTC. Income would be variable and depositors would share losses.
