BORROW AGAINST YOUR BITCOIN
Deposit Bitcoin and borrow USDU at rates you control, from 0.5%. Your Bitcoin is never lent out or rehypothecated, so you maintain full ownership and get it back when you repay. Use your USDU however you want: swap to USDC for off-ramps, deploy in DeFi, or hold as stable value.

How it works
Borrow at the lowest rates in four steps
Step 1
Deposit Your Bitcoin
Connect your wallet and deposit WBTC as collateral. Your Bitcoin stays under your control. No custody, no rehypothecation.
Step 2
Choose How Much to Borrow
Decide how much USDU to mint against your Bitcoin. Borrow what you need while maintaining a safe collateral ratio.
Step 3
Set Your Own Interest Rate
Choose the rate you want to pay, starting from 0.5%. Lower rates mean cheaper borrowing. This is what makes Uncap the lowest-cost way to borrow against Bitcoin.
Step 4
Repay Anytime
Use USDU however you want: swap it to USDC, use it in DeFi, or hold it. When you're ready, repay your loan and get your Bitcoin back.
