Get Dollar Liquidity Without Selling Your Bitcoin
Deposit BTC into a non-custodial vault. Borrow USDC or UNIT stablecoins. Repay any time and redeem your BTC in a single Bitcoin block.
02 · HOW IT WORKS
FOUR STEPS
/ 01
Deposit BTC
Lock your Bitcoin into a 2-of-2 Taproot multisig vault. One key is yours, the other belongs to the Guardian MPC network. No bridges, no wrapping, no custody transfer.
/ 02
Choose Your Terms
Set your collateral ratio from 160% (aggressive) to 250%+ (conservative). A higher ratio means a lower liquidation price and more safety margin.
/ 03
Receive USDC or UNIT
Borrow USDC for instant dollar liquidity, or UNIT (Bitcoin's native stablecoin). Pick USDC and the protocol mints UNIT behind the scenes, converts it 1:1 via Circle, and delivers USDC directly to you.
/ 04
Repay & Redeem
Repay your debt any time. Your BTC is released in a single Bitcoin block, not days or weeks. Once your debt is cleared, nobody can stop you from getting your Bitcoin back.
