For most of crypto-lending’s history, the default collateral was Bitcoin. ETH-backed loans existed but they were second-class — lower LTV ceilings, higher rates, and concerns about validator slashing and proof-of-stake dynamics. That changed in 2024-2025. Today every major lender treats ETH and BTC as roughly equivalent collateral, and liquid staking tokens have opened entirely new product lines. This guide explains how ETH loans differ from BTC loans on the dimensions that matter, and when to pick one over the other.
Why ETH loans were rare before 2024
The original concern was structural. After Ethereum’s transition to proof-of-stake in 2022, holding ETH became more nuanced — validators could be slashed for misbehavior, staked ETH was illiquid for withdrawal queues, and the price could decouple from the underlying asset during stressed market conditions. CeFi lenders priced this uncertainty into wider haircuts and lower LTV.
Two changes flipped the script. The Shapella upgrade in 2023 enabled validator withdrawals, removing the liquidity overhang. And the explosion of liquid staking tokens — stETH, rETH, cbETH — gave borrowers a way to keep earning staking yield while pledging the LST as loan collateral. We covered the broader landscape in Top 5 DeFi Lending Protocols in 2026.
How ETH and BTC loans compare today
The headline numbers in early 2026:
- LTV ceilings: ETH 50-70% on most platforms; BTC 50-75%. Roughly equivalent now.
- Interest rates: ETH 2-9% APR; BTC 1.9-9% APR. Effectively the same.
- Liquidation triggers: ETH platforms typically require slightly more buffer (because ETH historically has 10-15% higher daily volatility than BTC).
- Settlement asset: Both can be borrowed in fiat or stablecoins. ETH loans more often pay out in USDC/DAI given DeFi-native borrowers.
If you have both BTC and ETH, your choice usually comes down to two factors: which asset you want to keep exposure to (the pledge does not affect your upside), and whether you can use a liquid staking token to also earn yield while it sits as collateral.
Liquid staking tokens as collateral — the new flexibility
This is the biggest practical difference. With BTC, your pledged collateral sits in custody earning nothing. With ETH, you can pledge a liquid staking token (stETH from Lido, rETH from Rocket Pool) and continue earning ~3-4% staking yield throughout the loan term.
The math: if you borrow $50,000 against $100,000 of stETH at 7% APR, your net cost is roughly 7% – 3% (staking yield) = 4%. That is meaningfully cheaper than the equivalent BTC loan, which has no offsetting yield. Aave, Spark, and a handful of CeFi platforms (notably Ledn’s “Custody-as-Collateral” tier) accept LSTs natively.
The catch: LSTs occasionally trade at a small discount to the underlying ETH (especially during stressed markets). When that happens, your effective collateral is worth less than 1:1, and your LTV recalculates against the discounted LST price. Most of the time the depeg is under 1%, but it has been as wide as 7-8% during the worst stress events. Plan around that.
Rate dynamics: variable vs fixed
One subtle difference: ETH loans on DeFi (Aave, Compound, Spark) are almost always variable-rate, driven by the protocol’s utilization curve. As more borrowers tap the pool, the rate rises algorithmically. BTC loans are more often fixed-term on CeFi platforms. We unpack the mechanics in How Crypto Loan Interest Rates Are Calculated.
For a borrower who values predictable monthly cost, fixed-rate BTC loans on Ledn or APX are the cleaner choice. For a borrower who is rate-conscious and willing to monitor, DeFi ETH loans frequently price below the equivalent CeFi BTC loan during low-utilization periods.
Tax and regulatory differences
From a U.S. federal tax perspective, ETH and BTC are treated identically — both are property, both follow the same rules around pledging vs disposition. The new Form 1099-DA reporting (covered in our Form 1099-DA guide) applies to both equally.
The wrinkle is staking yield. If you pledge stETH and earn yield throughout the loan, that yield is taxable as ordinary income at the moment it is earned (per the 2023 IRS Revenue Ruling 2023-14). You pay income tax on the yield, separately from any capital-gains treatment when you eventually unwind the collateral. Don’t be surprised by the additional 1099-MISC.
When to pick ETH over BTC
A simple decision framework:
- Pick ETH collateral if: you can use a liquid staking token, you want a variable-rate DeFi loan, you are comfortable with slightly higher daily volatility, or you simply prefer to keep BTC exposure intact.
- Pick BTC collateral if: you want maximum LTV, you prefer fixed-rate terms, you value the longer track record of BTC lending products, or you are working with very large loan sizes ($500K+) where the BTC-loan market is deeper.
- Pick a mix if: your platform supports multi-collateral loans (covered in our upcoming multi-collateral guide). Diversifying across BTC and ETH reduces single-asset liquidation risk.
Frequently asked questions
Are ETH loan rates higher than BTC loan rates?
Not anymore. As of early 2026 they are effectively equivalent, both ranging from roughly 2 to 9 percent APR depending on platform, LTV, and term.
Can I earn staking yield while my ETH is pledged as collateral?
Yes, if you pledge a liquid staking token (stETH, rETH, cbETH) instead of raw ETH. The LST continues to accrue staking rewards even while sitting as loan collateral.
What happens if stETH depegs from ETH during my loan?
Your LTV recalculates against the discounted stETH price, which can push you closer to a margin call. Most platforms add a small buffer for this.
Which DeFi platforms support ETH-backed loans?
Aave is the largest by TVL. Compound, Spark Protocol, and MakerDAO (now Sky) are the next tier. Each has different risk parameters and rate models.
Should I take an ETH loan if I think ETH price will rise?
Yes, that is the core use case. An ETH-backed loan lets you access cash without selling your ETH, so you keep the upside if the price rises.
