Multi-Sig vs Custodial: Which Bitcoin Loan Custody is Right for You?
10 min read
Your Bitcoin. Their vault. Who holds the keys determines whether you get it back.
Custody decision
Decide who can move the BTC before you compare APR.
Custody model controls the failure mode. Multi-sig, custodial, and DeFi routes should not be compared as if they only differ by rate.
Most convenient
Custodial loans are simpler, but add counterparty trust.
Different lane
DeFi removes company custody but adds protocol risk.

Model, not advice
The right custody model depends on borrower operations and risk tolerance.
When you deposit BTC as collateral for a loan, you are making a trust decision. Every platform falls into one of three custody categories — multi-sig, non-custodial (DeFi), or custodial. The category you choose determines what happens if the platform fails, gets hacked, or makes a bad bet with your collateral. This page walks through each model and gives you a decision framework based on your situation.
The Three Custody Models
KEY
Multi-Sig (Collaborative Custody)
You hold keys — with redundancy
Your BTC is locked in a multi-signature vault requiring multiple keys to move. Unchained Capital uses a 2-of-3 model: you hold 2 keys, Unchained holds 1. The platform cannot move your Bitcoin without your cooperation, and if Unchained disappears, the design gives you a direct recovery path using your 2 keys. This is the clearest borrower-control custody model in our tracked CeFi lending set.
Strengths
- OKPlatform cannot unilaterally seize or move your BTC
- OKYou have a direct recovery path if the platform disappears
- OKClear legal ownership — you are not an unsecured creditor
- OKStrong protection against platform insolvency risk
Trade-offs
- NOMore complex setup — key management is your responsibility
- NOHigher APR than custodial options (14.18%; public pricing currently conflicts, verify before borrowing)
- NOLosing both your keys means losing your BTC permanently
Safety Score
9.0/10— highest in the category
DEF
Non-Custodial (DeFi)
Smart contracts hold the collateral
Your BTC goes into a smart contract — not a company vault. The contract is code: it holds your collateral and releases it when you repay. No human decides whether you get your BTC back. The rules are transparent and enforced on-chain. Aave and Maker are the genuinely non-custodial BTC-collateral options; Lava advertises 7.5%interest (plus a separate 2% annual capital charge) with no KYC, but its custody model is unresolved — reporting indicates a move to custodial cold storage as of Nov 2025 while Lava's site still markets self-custody, so do not treat it as confirmed non-custodial.
Strengths
- OKNo company can freeze, seize, or mismanage your collateral (Aave, Maker)
- OKLow published interest (Lava advertises 7.5% plus a 2% annual capital charge — but its custody is unresolved)
- OKNo KYC — privacy-preserving
- OKTransparent, auditable smart contract code
Trade-offs
- NOSmart contract bugs — code can have exploits
- NONo customer support if something goes wrong
- NOYou are your own safety net — mistakes are irreversible
- NOLower safety score (3.4/10) — unresolved custody and protocol risk
Safety Score
3.4/10— smart contract risk is the trade-off for self-custody
BNK
Custodial
Platform holds all keys
You transfer your BTC to the platform. They hold the keys, manage storage, and control access. You see a balance in their app, but you do not hold the private keys. If the platform fails, you may become an unsecured creditor in bankruptcy proceedings. This model often offers lower rates and simpler UX, but carries the highest counterparty risk.
Strengths
- OKCompetitive CeFi rates (Figure at 8.91% rate / 9.999% APR, Arch published from 7.25% for the largest loans with its tiered origination fee included in APR)
- OKSimplest user experience — no key management
- OKSome platforms use institutional or regulated custody infrastructure (BitGo, Anchorage, MPC setups)
- OKFastest loan origination for first-time borrowers
Trade-offs
- NOPlatform can freeze your funds at any time
- NOYou are an unsecured creditor if they go bankrupt
- NORehypothecation risk — they may lend out your BTC
- NOSafety scores range from 4.0/10 (YouHodler) to 7.4/10 (Ledn)
Safety Range
4.0–7.4/10— varies significantly by platform
Decision Tree: Answer Four Questions
Skip the analysis paralysis. Answer these four questions and we will point you to the right custody model — and the specific lender that fits.
1
Do you need the clearest recovery path if the lending platform goes bankrupt?
→ Multi-Sig (Unchained Capital)
In a 2-of-3 multi-sig, you hold 2 keys. Unchained cannot move your BTC without you, and the setup gives you a direct recovery path if they disappear. No other tracked CeFi model gives borrowers as much key control.

Want the lowest rate available and don't mind trusting open-source smart contract code instead of a company?
→ Non-Custodial DeFi (Aave / Maker)
Aave and Maker are genuinely non-custodial — your collateral sits in auditable smart contracts, no KYC, no company to trust, but you accept smart contract risk. Lava advertises a low headline rate (7.5% interest plus a separate 2% annual capital charge) but its custody model is unresolved — reporting indicates custodial cold storage as of Nov 2025 while its site still markets self-custody (safety score 3.4/10).

Need a regulated US lender with a simple fixed CeFi rate?
→ Custodial Bank (Figure)
Figure offers BTC-backed loans at 8.91% base rate (9.999% effective APR including origination fee). Your collateral is held via MPC custody under a BBB A+ rated entity, and the current public loan page says collateral will never be rehypothecated. Safety score: 7.1/10.
See Figure →4
Borrowing large amounts ($250K+) and want the custodial platform with the strongest track record?
→ Custodial Institutional (Ledn)
Ledn holds your BTC in custodial storage and publishes Open Book reporting and a semiannual Proof of Reserves program. APR is tiered by loan size (9.25–11.49%): it starts at 11.49% under $250K and 10.99% at $250K+. At $500K+, it falls to 10.49%, and at $1M+ it reaches 9.99%. A final 9.25% rung applies at $2M+. Note Ledn allows collateral to be re-posted to institutional funding partners (partial rehypothecation). Safety score: 7.4/10.

What Happened to Celsius
Celsius was one of the largest custodial Bitcoin lending platforms, holding over $12 billion in customer assets at its peak. They promised safe, high-yield returns and marketed themselves as a secure alternative to banks. But behind the scenes, Celsius was rehypothecating customer collateral — lending it out to third parties, investing in risky DeFi positions, and using customer funds to cover their own operating losses. When crypto markets crashed in 2022, Celsius could not meet withdrawal requests. They froze all accounts and filed for bankruptcy. Customers who had deposited BTC became unsecured creditors, meaning they stood at the back of the line in bankruptcy court. As of early 2026, many creditors are still waiting for partial recovery — receiving cents on the dollar for Bitcoin that was worth far more at the time of deposit.
The Celsius collapse illustrates the fundamental risk of custodial lending with rehypothecation. Your BTC is not sitting in a vault with your name on it — it is being lent out, traded, and risked by the platform. If enough of those bets go wrong simultaneously, there is nothing left to return. Multi-sig platforms like Unchained structurally prevent this: they cannot rehypothecate your collateral because they do not have enough keys to move it without your signature. Non-custodial DeFi platforms prevent it through code — the smart contract simply does not have a function to lend out your collateral. Custodial platforms can offer lower rates precisely because they profit from rehypothecating your BTC. The question is whether that rate discount is worth the risk.
The Bottom Line
If custody safety is your top priority
Go multi-sig with Unchained Capital (9.0/10 safety). You hold 2 of 3 keys, the platform cannot touch your BTC without you, and you can recover everything if they disappear. You pay more (14.18% APR; public pricing currently conflicts, so confirm a live quote) for that peace of mind.
If you want the lowest published BTC rate we track (custody unresolved)
Go non-custodial DeFi with Aave or Maker — you hold your keys via audited smart contracts, no KYC, no company trust. (Lava offers the lowest published rate (6.5%) but its custody model is unresolved as of Nov 2025.) But you need to be comfortable with smart contract risk and managing your own transactions.
If you want CeFi with banking-grade regulation
Go custodial with Figure (8.91% interest rate / 9.999% APR at 50% LTV, 7.1/10 safety) for a simpler fixed-term BTC loan with MPC custody and optional liquidation protection, or Ledn (9.25–11.49% APR, 7.4/10 safety) for custodial storage with Open Book reporting (collateral may be re-posted to institutional funding partners). Both are significantly safer than the Celsius model.
Platforms we would approach with caution
Nexo (5.3/10) and YouHodler (4.0/10) sit in the lower end of our tracked safety rankings. Wide APR ranges (quote-dependent) suggest variable pricing that may not favor every borrower. If you use these platforms, keep loan durations short and LTV conservative.
The useful job of this page is not to push you from a custody explainer into a compare flow. It is to help you decide whether borrower control, platform failure risk, or convenience is the real constraint before you narrow the field.
If you are still deciding, the next useful move is usually to pressure-test custody tradeoffs, collapse scenarios, and borrower fit before you look at any one lender list.
