Custodial platforms handle keys and support.
Custodial vs Non-Custodial
5 min read
Quick decision
Before APR, decide who can move the Bitcoin.
Custody is the control question: platform, collaborative multisig, or smart contract. The right model depends on how much key control and support you want.
Most control
Collaborative multisig keeps you closer to the keys.
Most operational
DeFi replaces company custody with contract risk.
Search-intent shortcut
Start here if the real question is key control, not APR
This guide is designed for users who keep hearing custody language and want the fastest possible explanation of what changes when the platform, a multisig partner, or a smart contract controls the collateral.
Best for
Borrowers trying to understand who controls keys before they compare rates or lender features.
Not for
Users who already trust their custody setup and only need the best BTC loan terms right now.
Best next step
Use the control-model guides for key-control research, or move into risk follow-ups if control setup is still the deciding factor.
The three custody models
Custodial
Platform holds all keys
The platform holds your private keys. They manage storage, security, and access. You have an account balance, not direct key control over the Bitcoin. This is the closest crypto version of a bank-like experience.
Pros
- OKEasy to use
- OKSome providers use insured or regulated custody partners
- OKPlatform can facilitate faster loan workflows
Cons
- NOPlatform can freeze your funds
- NOYou are an unsecured creditor if they fail
- NORehypothecation risk — they may lend your BTC out
Platforms: Ledn, Nexo, YouHodler
Multi-Sig (Collaborative)
You hold keys — with help
You hold some keys, the platform holds others. Unchained's model is 2-of-3 keys where you hold 2 and Unchained holds 1. The platform needs your cooperation to move funds, while you still carry key-management responsibility.
Pros
- OKPlatform cannot unilaterally move funds
- OKYou retain more key control
- OKClearer legal ownership
Cons
- NOMore complex setup
- NOYou must safeguard your keys
- NOPlatform still exists — counterparty risk remains
Platforms: Unchained (2-of-3 collaborative vault)
Non-Custodial / DeFi
Smart contracts hold the collateral
Your BTC goes into a smart contract. The contract is code: it holds your collateral, follows repayment rules, and liquidates according to its parameters. You reduce company-custody risk, but you accept protocol, oracle, and execution risk.
Pros
- OKNo direct company-custody risk
- OKTransparent rules when the code and positions are public
- OKNo KYC required on many protocols
Cons
- NOSmart contract bugs — code can have vulnerabilities
- NOYou are responsible for everything
- NONo customer support if you make a mistake
Platforms: Aave, MakerDAO (Sky) vault. Note: a custody model can change — Lava marketed self-custody but reporting (Bitcoin Magazine, Nov 2025) indicates a move to custodial cold storage, so Pledge currently treats its custody as unresolved.
What custody looked like in practice: 2022
Three major platforms failed in 2022. Here's how custody affected each outcome:
Celsius — Custodial
Celsius held customer funds in a custodial model. When they failed, customers became unsecured creditors. Many are still recovering cents on the dollar years later. Celsius also rehypothecated customer collateral — lending it out for yield. Customer funds were used to generate returns that benefited Celsius, not depositors.
FTX / Alameda — "Custodial" in name only
FTX claimed to hold customer funds separately. In practice, Alameda used customer deposits to cover its own trading losses. The custody was theater. This wasn't just a failed platform — it was fraud. The lesson: a platform claiming to be custodial means nothing without reserve transparency and legal separation.
Voyager — Custodial
Voyager held customer crypto assets and lent them out (rehypothecation). When Three Arrows Capital defaulted on loans it had taken from Voyager, Voyager didn't have enough liquidity to return all customer funds. Customers received partial recovery through bankruptcy proceedings — after months of uncertainty.
What non-custodial users experienced
Users who had used DeFi protocols like MakerDAO through proper non-custodial wallets had a different risk profile: collateral was controlled by smart contracts, not a company balance sheet. Smart contract risk still exists, but the failure mode is not the same as a centralized company pausing withdrawals or entering bankruptcy.

Control-model follow-ups
Use the control-model guides as the place to keep this research grounded.
This guide should help you understand the decision, not open a second pseudo-category. Follow the guide layer once you know control model is still the thing that matters.
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, bankruptcy protection, or smart-contract risk is the real issue before you narrow the field.
