Non-custodial vaults on Bitcoin L1. Zero ongoing interest. On-chain verification. Programmatic access via SDK.
A flat 1% origination fee. No APR, no compounding, no hidden charges. CeFi lenders charge 2-12% annually. On a $10M loan held for 12 months, that difference is $200K-$1.2M saved.
Your BTC sits in a Taproot multisig vault on Bitcoin L1. One key is yours, the other belongs to the Guardian MPC network. No single party can move funds. No counterparty risk from a custodian balance sheet.
No bridges, wrapped tokens, or sidechains. Every vault, liquidation, and redemption settles directly on Bitcoin. The security model is Bitcoin's security model. Your compliance team can verify every transaction on-chain.
Borrow UNIT (Bitcoin-native stablecoin) or receive USDC directly. UNIT converts 1:1 to USDC via the Circle SDK. No need to find a secondary market or manage a new token position.
Built for auditability. Every component is independently verifiable.
2-of-2 multisig structured as a tap tree with two spending paths: redemption (borrower repays) and liquidation (collateral falls below 135%). Script-enforced, deterministic, auditable.
11-of-15 FROST threshold signature scheme. Guardians co-sign vault operations but cannot alter transactions, redirect funds, or sign paths that don't exist in the tap tree. Full DKG key rotation without vault interruption.
Custom-built integration for Bitcoin. Price attestations delivered via hash-lock commitments in OP_RETURN data. The oracle signs prices, not transactions. Guardians cross-check against an independent secondary feed.
Anyone can run a validator. Validators parse Bitcoin data, reconstruct full protocol state from on-chain OP_RETURN metadata, and produce a deterministic ledger. No signing power, only verification.
Rust-based SDK for programmatic vault management. Build BTC transactions locally, manage positions, monitor collateral ratios, and automate redemptions. All operations are standard Bitcoin transactions.
UNIT transfers via Cashu ecash protocol. Instant, feeless, and private. Useful for treasury operations, inter-entity settlement, and high-frequency UNIT movements without on-chain fees.
We walk through your custody setup, compliance requirements, and borrowing needs. Typical call takes 30 minutes. No commitment.
Integrate the Ducat SDK into your existing infrastructure. The SDK handles vault creation, collateral management, and redemption. Your team maintains full control of key material.
Run your full workflow on testnet. Open vaults, borrow UNIT, test redemption, simulate liquidation scenarios. Verify everything before committing real BTC.
Deploy to mainnet. Your BTC stays in non-custodial vaults on Bitcoin L1. Monitor positions via the SDK or the Ducat dashboard. Redeem at any time in a single Bitcoin block.
