How It Works

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.

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.

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.

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.
