Ducat Protocol

About this app

Ducat Protocol is a Bitcoin-native credit and stablecoin system that lets you borrow dollar-pegged stablecoins (UNIT or USDC) against your BTC without selling or giving up custody. Your Bitcoin stays in a non-custodial Taproot vault enforced by Bitcoin Script, so you keep full control. There's a one-time 7% minting fee and zero ongoing interest, making it a tax-efficient way to unlock liquidity. UNIT is a Runes-based stablecoin backed by overcollateralized BTC, swappable 1:1 to USDC. With features like single-block redemption, real-time health monitoring, and community-run liquidations, Ducat is pioneering DeFi on Bitcoin L1. It's currently in mainnet closed alpha with over $700M in BTC vaulted and $300M in UNIT minted.

Scout Review

Written by AI from measured evidence, scored out of 100.

Ducat Protocol is a Bitcoin L1-native credit protocol that lets you borrow UNIT or USDC against BTC in a non-custodial Taproot vault, with a one-time 7% minting fee and 0% ongoing interest. The pitch is sharp and the positioning against Aave, MakerDAO, and Liquid Network is genuinely differentiated — no bridges, no wrapping, no custodians. The site is fast (Lighthouse 85 mobile / 96 desktop) and the landing page does a good job explaining a complex product via a live loan calculator. The weaknesses are stage-appropriate but real: closed alpha with Discord-gated access, no public docs surfaced, missing security headers, no named third-party audit, and accessibility contrast/landmark issues. It's a credible early-stage protocol with a clear idea and a lot of trust-building left to do.

Measure by measure

Usability

Loan calculator and step-by-step explainer make the concept graspable, but 'Mainnet Closed Alpha' with Discord-gated access means no open signup, no public docs link, and no self-serve path to value yet.

Design

Dark, modern DeFi landing page with a live loan calculator, clear 'How It Works' flow, and credible protocol diagrams. Polished for an alpha-stage Bitcoin protocol, though it's marketing UI rather than the actual dashboard.

Speed

Lighthouse mobile 85/100 and desktop 96/100 with TBT 9ms and CLS 0.048 — genuinely snappy. The 3.3s mobile LCP/FCP drags it down from excellent, but the site feels fast.

Security

HTTPS+HSTS, SPF, DMARC in place, and a non-custodial 2-of-2 Taproot vault is a strong architectural claim. But no CSP, frame protection, or other hardening headers, and no published audit or SOC 2.

Accessibility

Lighthouse a11y 94/100 is solid, but failing audits flag insufficient color contrast, non-sequential headings, and a missing main landmark — the exact issues dark DeFi sites always have. No a11y statement found.

Growth

Real, specific pain (liquidity without a taxable BTC sale), a genuine wedge vs Aave/MakerDAO/Liquid (native L1, no bridges, 0% APR), and a category with headroom. Self-reported $700M vaulted is context, not proof.

Improvement areas

Closed alpha with Discord-gated access and no public docs or self-serve signup limits onboarding and trust.
No named third-party audit, SOC 2, or bug bounty despite claiming $700M+ in vaulted BTC.
Missing security headers (CSP, frame protection, X-Content-Type-Options, Referrer-Policy, Permissions-Policy) and a11y contrast/landmark failures.

Design & Usability

Ducat's site is a competent dark-mode DeFi landing page: gradient hero, a working loan calculator with a collateral-ratio slider, and a clean three-step 'How It Works' that actually explains the product. For an alpha-stage Bitcoin protocol, that's above average craft. The usability story is weaker. The product is in 'Mainnet Closed Alpha', so there's no open signup, no public free trial, and no self-serve path — onboarding runs through a Discord invite. The calculator does real work in explaining the 7% fee and 0% APR, but a prospective borrower can't actually try the vault flow without getting let in. The gap between 'I understand this' and 'I can use this' is currently a Discord server.

Speed & Security

Speed is a genuine strength. Lighthouse scores 85/100 on mobile and 96/100 on desktop, with TBT of 9ms and CLS of 0.048 — the page is stable and responsive. The 3.3s mobile LCP and FCP are the only real drag, likely from hero media and the calculator widget. Security is more mixed. HTTPS is enforced with HSTS, and SPF/DMARC are configured, which covers the basics. But the header probe found no CSP, no frame protection, no X-Content-Type-Options, no Referrer-Policy, and no Permissions-Policy — 6 of 12 checklist points. The protocol's core security argument (non-custodial 2-of-2 Taproot vaults enforced by Bitcoin Script) is architecturally interesting, but no third-party audit, SOC 2, or bug bounty is named in the material reviewed, which is a notable gap for a system holding $700M in claimed BTC.

Accessibility & Growth

Accessibility lands at a solid 94/100 on Lighthouse, but the failing audits are the usual dark-theme suspects: insufficient color contrast, non-sequential heading order, and a missing main landmark. No accessibility statement or multi-language support was found. Growth is the most interesting dimension. Ducat names a real, specific problem — Bitcoin holders who want dollar liquidity without triggering a taxable sale or surrendering custody — and its wedge against Aave, MakerDAO, and Liquid Network is concrete: native Bitcoin L1, no bridges, no wrapping, 0% APR with a one-time 7% fee. That's a differentiated position in a category with visible headroom. The honest limit is trust: a 7% upfront fee on a closed-alpha protocol with no published audit is a hard sell, and the $700M/$300M figures are self-reported. The idea can grow; the execution risk is real.

Conclusion

If you're a BTC holder who wants liquidity without a taxable sale and you're comfortable being early, Ducat is worth watching — the architecture is the interesting part, and the 0% APR / 7% one-time fee model is a real alternative to selling. But 'closed alpha' plus '$700M vaulted' plus 'no published audit' is a combination that demands caution, not FOMO. Wait for an open beta, a named audit, and a public docs page before you move meaningful BTC into a vault. The idea deserves attention; the current access model doesn't yet deserve your coins.

Suggestions for improvement

Publish a named third-party security audit and a bug bounty program before scaling vault TVL further.
Open a public docs/help center and a testnet sandbox so users can try the vault flow without Discord access.
Add the missing security headers (CSP, frame protection, X-Content-Type-Options, Referrer-Policy, Permissions-Policy).
Fix the accessibility failures: color contrast, sequential heading order, and a main landmark; add an a11y statement.
