];The Ducat SDK builds BTC transactions locally according to the protocol specification which includes a series of spending conditions that allow your BTC to be permissionlessly redeemed so long as the remaining UNIT in the vault is collateralized adequately.
Monitor your vault, track your collateral ratio, and manage loans from one dashboard. Every transaction settles on Bitcoin L1.
Every vault and loan term is recorded on Bitcoin. Anyone can run a validator and independently verify the entire protocol state.
No sidechains, no bridges, no wrapped tokens. Vault custody and liquidation rules are enforced directly by Bitcoin Script.
One-time 1% origination fee. No ongoing interest, no hidden charges. Repay your loan and redeem your BTC in a single Bitcoin block.
Your BTC sits in a 2-of-2 Taproot vault. No single party can move your funds. Redeem your Bitcoin any time by repaying your loan.
When vaults fall below the 135% collateral threshold, anyone can buy discounted BTC by recapitalising the position. Approximately 8-9% ROIC per liquidation.

Everything you need to know about borrowing against your Bitcoin.
Ducat is a Bitcoin L1-native credit and stablecoin protocol. It lets BTC holders borrow dollar-pegged stablecoins (UNIT or USDC) against their Bitcoin without surrendering custody. All loan logic, including vaults, liquidations, and redemptions, is enforced by Bitcoin transactions and Script. No L2s, no bridges, no external chains.
Your BTC is locked in a 2-of-2 Taproot multisig vault: one key is yours, one belongs to a Guardian group (an 11-of-15 MPC threshold network). Neither side can move funds alone. The vault can only be spent in two ways: you repay and redeem your BTC, or the vault is liquidated because collateral dropped below 135%. There is no way to rehypothecate or redirect your Bitcoin.
UNIT is a dollar-pegged stablecoin issued natively on Bitcoin L1 using the Runes token standard. It is backed by overcollateralised BTC locked in vaults and soft-pegged to USD in the $1.01 to $1.04 range. The peg is maintained through overcollateralisation and arbitrage: if UNIT trades below $1, buyers purchase it cheaply to close vaults at a profit, pushing the price back up.
Yes. When you choose to borrow USDC, Ducat mints UNIT behind the scenes and converts it 1:1 to USDC via the Circle SDK. You receive USDC directly without needing to interact with UNIT at all. Repayment works the same way in reverse: send USDC, and the protocol handles the conversion and vault closure automatically.
No. Ducat charges a one-time origination fee of 1% when you open a loan. There is no ongoing interest, no compounding, and no hidden charges. Repay your debt any time and redeem your BTC in a single Bitcoin block. The zero-interest model also makes Ducat Sharia-compliant.
Selling BTC means giving up your position. If Bitcoin rises after you sell, you miss the upside. Borrowing lets you access dollar liquidity (UNIT or USDC) while keeping full exposure to BTC. When you are ready, repay the loan and get your Bitcoin back. No taxable sale event, no lost upside.
If BTC drops and your vault's collateralisation falls below 135%, the vault becomes eligible for liquidation. The exact BTC price that triggers this is calculated and locked at the time you open the vault, recorded on-chain so you always know your liquidation price. Liquidation requires two independent confirmations: a Chainlink oracle attestation and Guardian verification against a secondary price feed.
Keep your collateralisation ratio well above the 135% liquidation threshold. You can do this by depositing additional BTC into your vault or by repaying some of your outstanding debt. The Ducat dashboard shows your real-time health factor and liquidation price so you can monitor your position and act before it reaches the danger zone.
The main risks are BTC price volatility (which can trigger liquidation if your collateral drops below 135%), potential oracle or Guardian failure (mitigated by secondary price feeds and threshold signing), and general software risk as Ducat is experimental protocol software under active development. Ducat is not available to US persons. Always assess your own risk tolerance before depositing.
If the Chainlink oracle goes down, no new borrows or liquidations can occur, but your BTC remains safe in its vault. Vaults with no outstanding debt can still be closed. Ducat is also integrating backup oracles (Stork, Pyth, Chaos Labs) for redundancy. If the website goes down, the front end is open-source with community mirrors, and the protocol continues operating via independent validators and Guardians on Bitcoin L1.
