If there's one concept every Bitcoin borrower should understand before choosing a platform, it's rehypothecation. It's the reason Celsius lost customer funds. It's the reason BlockFi went bankrupt. And it's a policy that varies dramatically between BTC lending platforms — some do it, some don't, and the difference matters enormously.
Key Takeaways
- 1Rehypothecation means the platform can lend or invest your collateral to earn yield.
- 2Current public sources now put Figure in the no-rehypothecation group, while Nexo and YouHodler still require account- or form-level confirmation.
- 3No-rehypothecation language or architecture is strongest for Ledn, Unchained, Figure, Arch, Lava, Xapo, Strike, and SALT.
- 4No rehypothecation is the single strongest predictor of collateral safety after custody model.
What Is Rehypothecation?
In traditional finance, rehypothecation is when a lender uses collateral posted by a borrower as their own collateral for another transaction. In crypto lending, it means the platform takes your Bitcoin and uses it to:
- Lend it to other borrowers
- Provide liquidity to DeFi protocols
- Use it as collateral for their own borrowing
- Trade it for yield generation
The core problem: If the platform's rehypothecation strategy generates losses, your collateral is gone. This is exactly what happened with Celsius — they rehypothecated customer deposits into risky DeFi strategies that failed.
How to Check a Platform's Policy
Every platform should disclose their rehypothecation policy. Look for it in:
- Terms of service
- FAQ sections
- Independent reviews (like Pledge's safety scores)
Red flags:
- Policy is not clearly stated
- Uses vague language like "collateral may be deployed"
- Policy is "undisclosed"
Platform Comparison
| Platform | Policy | What It Means |
|---|---|---|
| Ledn | None | Your BTC sits in BitGo custody. Not moved, not lent. |
| Unchained | None | Multi-sig vault. You hold 2 of 3 keys. Physically impossible to rehypothecate. |
| Arch | None | Anchorage Digital custody. Insured, bankruptcy-remote. |
| Lava | Claimed none | Custody model unresolved — reporting indicates a Nov 2025 move to custodial cold storage while the site still markets self-custody, so "no rehypothecation" is a claim, not an architectural guarantee. |
| Figure | None | Current official loan page says collateral will never be rehypothecated. |
| Nexo | Confirm | Account-level collateral terms should be confirmed before borrowing. |
| YouHodler | Partial | Collateral used for platform operations including leverage products. |
Why "Partial" Is Not Reassuring
Platforms with "partial" rehypothecation rarely specify exactly what portion of your collateral is re-lent or what strategies it's used in. The ambiguity itself is a risk:
- During normal markets: Rehypothecation is invisible. The platform earns yield, you get your loan. Everything appears fine.
- During market stress: Rehypothecation becomes dangerous. If the platform's yield strategies lose money, or if too many borrowers default simultaneously, the platform may not have sufficient assets to return your collateral.
The 2022 Lesson
Celsius rehypothecated customer deposits into:
- DeFi yield farming (stETH/ETH liquidity pools)
- Mining operations
- External lending
When crypto markets crashed in June 2022, these positions lost value rapidly. Celsius couldn't meet withdrawal requests because customer assets were locked in underwater positions. The result: bankruptcy and months of legal proceedings for customers to recover partial funds.
BlockFi followed a similar pattern, ultimately filing for bankruptcy in November 2022.
Why Some Platforms Don't Rehypothecate
Platforms with no-rehypothecation language or architecture (Unchained, Arch, Lava, Figure, Xapo) make money differently. Ledn is a special case: it publishes Open Book reporting, but its current materials allow re-posting collateral to institutional USD funding partners while prohibiting lending BTC collateral out for yield:
- Ledn: Charges APR to borrowers and publishes Open Book reporting. Current materials say collateral may be re-posted to trusted institutional USD funding partners, while prohibiting lending BTC collateral out for yield.
- Unchained: Charges origination fees and annual vault fees. Revenue comes from service fees, not yield farming.
- Arch: Similar to Ledn — profit from interest rate spread.
- Lava: Protocol-level fees from smart contract operations.
The trade-off: No-rehypothecation platforms may charge slightly higher rates, but your collateral is significantly safer.
Our Recommendation
When comparing BTC lending platforms, rehypothecation policy should be one of your top decision factors — alongside custody model and reserve transparency.
If you would not be comfortable with your BTC being re-lent to unknown third parties, choose a platform with a "none" policy.
