Borrowing Against BTC: Nexo, Ledn, Aave, Morpho and Babylon Compared

[wapwapwendy]

Bitcoin-backed lending gives holders another option when they need liquidity without immediately selling their BTC. But the way these lending platforms handle collateral can be quite different.

Some use centralized custody, others rely on smart contracts and tokenized BTC, while newer designs aim to let borrowers use native Bitcoin without wrapping or bridging it.

1. Nexo and Ledn: Centralized lending

Nexo offers crypto-backed credit lines where users can borrow against supported assets, including BTC. Rates and borrowing limits depend on the applicable product and account conditions.

Ledn also provides Bitcoin-backed loans. Its published loan terms describe a typical starting loan-to-value (LTV) ratio of 50%, with liquidation at 80%.

Both offer a managed borrowing experience, but users need to understand the custody arrangements and what happens to their collateral if market conditions change.


2. Aave and Morpho: On-chain lending

Aave allows users to borrow against supported crypto collateral through smart contracts. Existing Bitcoin-related DeFi markets commonly use tokenized BTC, such as WBTC or cbBTC.

Morpho offers individual lending markets with different collateral assets, interest rates, liquidity conditions, and liquidation thresholds.

These systems offer on-chain transparency, although borrowers still need to consider smart contract risks, tokenized BTC dependencies, and variable borrowing rates.


3. Babylon: Native Bitcoin collateral

Babylon is developing Trustless Bitcoin Vaults, which are designed to let BTC holders lock native Bitcoin on the Bitcoin blockchain and use it as collateral through supported DeFi integrations.

Unlike conventional tokenized BTC lending, this approach does not require wrapping or bridging the collateral.

On November 9, 2026, the Aave DAO approved the ARFC for Babylon's proposed Aave V4 integration.

However, the integration is not yet a live mainnet borrowing service. Further governance and deployment steps are still required.

What matters beyond interest rates?

When comparing these options, I think there are several things borrowers should consider:

- Custody: Who controls the Bitcoin collateral?
- Collateral type: Native BTC or tokenized BTC?
- LTV: How much can someone borrow relative to their collateral?
- Liquidation: What happens if BTC drops sharply?
- Borrowing costs: Are rates fixed, variable, or dependent on loan terms?
- Transparency: Can users verify how their collateral is managed?
- Availability: Is the service live, and who can access it?

For me, the cheapest borrowing rate doesn't automatically mean the best option. A borrower also needs to understand how the collateral is secured, the conditions for repayment, and what could trigger liquidation.

Centralized platforms may appeal to users who prefer a managed experience. On-chain lending offers more transparency, while native BTC collateral designs aim to reduce reliance on wrapped assets.

Each approach has trade-offs, and none removes the financial risks of borrowing.

If you were borrowing against your BTC, what would matter most to you: custody, interest rates, liquidation rules, or keeping your Bitcoin on its native chain?

The most challenging problem about this is actually the custody of the bitcoin, personally I do think that if you’re borrowing since you must have to wrap your bitcoin that is your bitcoin leaving its native chain I will warn against the risk of doing that because if the lending platform actually collapses then this wrapped coins becomes useless.

You hand over your real bitcoin to this platforms and with the rate at which smart contracts are been exploited you’re definitely putting your bitcoin under danger In the process of acting smart and borrowing against your bitcoin. Lending platforms are totally a no for me due to the risk

Your post looks more like an advertisement of these services, even if that probably wasn't your intention. It kind of makes the topic fit in the Service Discussion section of the forum, rather than here, but we'll let the mods decide on that.

However, we have discussed a lot about these lending services, my opinion still remains the same, it is not something i would personally do. I do not want to lose custody of my coins to a third party that could lose them. There are other traditional ways to access loans and i would rather explore that option, while my BTC stays in my self-custodial wallet.

I have thought of this and considered to keep my BTC and borrow against it whenever I need some cash. But I also have my reservation in doing it, I'll have to pay interest and there's also the liquidation rules which shouldn't go equal or half of your total bitcoin that you're going to borrow against with. If I'll be needing some money, I might just sell it instead of borrowing against it since there rules are subject to change as well and I don't like paying interest of my own asset while losing custody of it temporarily or permanently if something goes wrong to these platforms.

The most challenging aspect of borrowing against your bitcoin is having a third party control your bitcoin and temporarily take custody of it. The question that demands an answer is: if the lender loses those bitcoins due to a hack or any other form of unauthorised access, will the borrower be compensated if they decide to repay the loan and claim back their bitcoins?

If there is no certainty here, then the borrower should seek other means of sorting out their financial needs. Borrowing against your bitcoin adds another layer of risk to your bitcoin investment. So, if you have other options, why use your bitcoins?
