Ethereum-Backed Loans: How to Borrow Against ETH (2026)

Last updated: 4 October 2026

Short answer: an Ethereum loan (or ETH-backed loan) lets you deposit ETH as collateral and borrow a different asset against it, usually a stablecoin such as USDC, without selling your ETH. You pay interest, you get your ETH back when you repay, and if ETH falls far enough that your loan-to-value ratio crosses the lender's threshold, part of your collateral is sold to repay the debt. In October 2026 you can do this on DeFi protocols such as Aave, Morpho and Liquity, or through centralized lenders and exchanges that wrap those protocols.

Ethereum-backed loans have become one of the clearest examples of what decentralized finance actually does: they let you unlock liquidity from crypto you already hold, without selling it. Instead of cashing out your ETH and losing your position, you pledge it as collateral and borrow against it. In 2026 this pattern powers a large share of on-chain credit, and the same model now runs on chains far beyond Ethereum.

This guide explains how ETH-backed loans work, the real 2026 numbers for how much you can borrow against ETH, a step-by-step walkthrough, the mechanics you must understand before borrowing, and how JewelSwap brings the same crypto-backed lending model to MultiversX, Sui and Radix.

What are Ethereum-backed loans?

An Ethereum-backed loan is a loan where you deposit ETH (or an ETH-based token) as collateral and receive a different asset in return, usually a stablecoin. You keep ownership of your ETH in the sense that you can reclaim it by repaying the loan plus interest. If you fail to maintain the loan safely, the protocol can sell your collateral to recover what it lent. The term is often used interchangeably with crypto-backed loans, because the same structure works with almost any liquid crypto asset. Our guide to borrowing against crypto without selling covers what each collateral type supports, and the broader crypto-backed loans guide compares collateral types side by side.

The appeal is simple. If you believe your crypto will appreciate, selling it to raise cash means giving up future upside and, in many jurisdictions, triggering a taxable event. Borrowing against it lets you access spending power while staying invested. As Ethereum's own explainer on DeFi puts it, you can use ETH as collateral for a stablecoin loan without credit checks or handing over private information.

Demand is not hypothetical. Crypto-collateralized lending reached $73.6 billion at the end of Q3 2025, the highest quarter-end figure on record, according to data cited by The Block (20 November 2025). Traditional finance has moved too: JPMorgan was reported in October 2025 to be preparing to accept bitcoin and ether as loan collateral for institutional clients, held by a third-party custodian.

Where you can borrow against ETH in 2026

Most "ETH loan" products fall into four groups. The numbers below are each venue's published parameters on the date cited; they change through governance or company policy, so check them on the day you borrow.

A few details matter more than the headline LTV:

• Coinbase's product is on-chain underneath. Coinbase added ETH as collateral in November 2025 and staked ETH (cbETH) in January 2026, both executed through the Morpho protocol on Base. Loan originations through the US product passed $2.17 billion in USDC by 14 April 2026, per Morpho's Coinbase case study.
• Liquity V2 has a different risk. Borrowers choose their own interest rate, and when the BOLD stablecoin trades below peg, loans with the lowest rates are redeemed first: part of your debt is repaid with your collateral. That is not a liquidation, but it can close your position when you did not plan to.
• Parameters can change overnight. After the April 2026 Kelp rsETH bridge exploit, Aave temporarily set WETH's LTV to 0% across V3 instances before restoring it to 80.5% (Aave governance, 9 May 2026). Existing loans were not liquidated by that change, but nobody could open new borrowing against WETH while it lasted.

For a wider list of lenders, including non-Ethereum options, see our roundup of Aave alternatives.

How to borrow against ETH: step by step

The flow below is the generic DeFi version. Interfaces differ, but every reputable money market follows this order.

1. Decide how much you actually need. Work backwards from the amount, not forwards from the maximum LTV. The less you borrow relative to your collateral, the larger the price drop you can survive.
2. Use a wallet you control. Connect a non-custodial wallet, ideally backed by a hardware device. Keep some ETH aside for gas fees.
3. Verify the app address. Type the protocol URL yourself or use a bookmark. Fake lending front ends are a common phishing route; our guide to wallet drainers and approval phishing explains what to look for in a signature request.
4. Supply ETH as collateral. On most protocols plain ETH is wrapped to WETH automatically. Confirm it is enabled as collateral.
5. Borrow a conservative amount. Before you confirm, read the projected health factor or LTV. A health factor near 1.0, or an LTV a few points from the threshold, is a position one bad candle away from liquidation.
6. Write down your liquidation price. Most interfaces show it. Set a price alert well above it.
7. Monitor and adjust. If ETH falls, either repay part of the loan or add collateral before the threshold, not after.
8. Repay and withdraw. Repay the borrowed asset plus accrued interest, then withdraw your ETH. Keep a little extra of the borrowed asset, because interest accrues every block.

Over-collateralization: the foundation

The single most important concept in ETH-backed lending is over-collateralization. In traditional finance, lenders assess your income and credit history before extending unsecured credit. On-chain protocols have no way to chase a borrower who disappears, so they solve the trust problem differently: they require you to deposit collateral worth more than the amount you borrow.

The surplus is a buffer. It absorbs price swings and protects the lenders whose deposits fund your loan. Over-collateralization is what makes permissionless, identity-free borrowing possible. It replaces the credit check with verifiable math enforced by smart contracts. The rare exception, borrowing with no collateral inside a single transaction, is a flash loan, which is a developer tool rather than a way to raise cash; see crypto loans without collateral for why.

Loan-to-value (LTV) and borrow limits

The relationship between how much you borrow and how much collateral you posted is expressed as the loan-to-value ratio. A lower LTV means a larger safety buffer; a higher LTV means you are borrowing closer to the maximum the protocol allows.

Every asset has a maximum borrow limit set by the protocol based on how volatile and liquid it is. Highly liquid, established assets typically support higher borrowing capacity, while thinner or more volatile assets support less. Conservative borrowers keep their LTV well below the ceiling so ordinary market moves never push them into danger.

The arithmetic is worth doing explicitly rather than by feel. At 70% LTV against an 80% liquidation threshold, a 12.5% decline is enough to liquidate you. At 40%, you survive a 50% fall. Our dedicated guide to crypto loan LTV works through the full calculation and how to pick a ratio you can live with.

Worked example: borrowing against 10 ETH

Assume ETH is $4,000, so 10 ETH is $40,000 of collateral, on a market with an 83% liquidation threshold (Aave's current WETH setting):

• Borrow $28,000 (70% LTV): liquidation when collateral falls to $28,000 / 0.83 = about $33,735, a drop of roughly 16% to an ETH price near $3,373.
• Borrow $16,000 (40% LTV): liquidation at about $19,277, a drop of roughly 52% to an ETH price near $1,928.
• Borrow $8,000 (20% LTV): liquidation at about $9,639, a drop of roughly 76%.

The formula is: liquidation price = debt / (collateral amount x liquidation threshold). ETH has suffered drawdowns of well over 50% in past bear markets, such as 2018 and 2022, so the middle line is a reasonable minimum buffer for a loan you plan to hold through a cycle. Borrowing to buy more ETH turns this into leverage, which shrinks the buffer further.

Liquidation: when the buffer runs out

Because crypto prices move constantly, the value of your collateral changes minute to minute. If ETH falls, your LTV rises even though you never touched the loan. When your position crosses the protocol's liquidation threshold, it becomes eligible for liquidation: the protocol sells part or all of your collateral to repay the debt, usually applying a penalty. On Liquity V2, for example, a liquidated borrower usually incurs a 5% penalty, according to the Liquity documentation.

Liquidation is not a punishment; it is the mechanism that keeps the system solvent so lenders can always be repaid. But it is costly for the borrower, so avoiding it is the goal. Understanding exactly where your liquidation point sits before you borrow is non-negotiable. Our full guide to DeFi liquidations and health factor covers partial liquidations, penalties and how to defend a position.

Borrowing against staked ETH and LSTs

You do not have to post plain ETH. Many borrowers use a liquid staking token such as wstETH, rETH or cbETH, so the collateral keeps earning staking rewards while the loan is open. That can partly offset borrowing costs, but it adds layers of risk:

• Depeg risk. An LST can trade below the ETH it represents. If the market prices it lower, your LTV rises even if ETH itself is flat. Our explainer on depegs covers how this unfolds.
• Lower limits. Protocols usually allow less borrowing against LSTs than against ETH; Liquity V2 caps wstETH and rETH at 83.33% LTV versus 90.91% for ETH.
• Bridge and restaking risk. In April 2026 an attacker exploited Kelp DAO's LayerZero bridge configuration to release 116,500 unbacked rsETH, then deposited 89,567 rsETH on Aave as collateral and borrowed roughly $190 million in ETH and related assets. Losses for Aave were estimated at between $123 million and $230 million (CoinDesk, 20 April 2026). OpenZeppelin's post-mortem notes that no code bug was involved: it was a single-verifier bridge setup. If you hold or lend against a restaking token, its bridge design is part of your collateral risk.

Where the interest comes from: money markets

ETH-backed loans in DeFi are powered by money markets, pooled lending markets where one side supplies assets and the other borrows them. Suppliers deposit into a pool and earn yield; borrowers post collateral and draw from that pool, paying interest. Rates are typically algorithmic, rising as more of the pool is borrowed and falling when it sits idle; that ratio is the utilization rate.

This design is elegant because it is two-sided. The interest a borrower pays is the yield a supplier earns. If you want to lend rather than borrow, the same pools are how you put idle assets to work. We cover that angle in our guide on how to earn yield on stablecoins.

Isolated vs cross lending markets

Modern money markets come in two main structures, and the difference matters for your risk.

Isolated markets ring-fence each asset or pair. Risk from one market cannot cascade into another, which is ideal for newer or more volatile assets and for risk-conscious users. Cross (or global) markets let you collateralize a whole portfolio at once, using several deposited assets together to back your borrowing. This maximizes capital efficiency but demands stronger risk management, because a drop in any one collateral asset affects the entire position. The same distinction exists in trading as cross vs isolated margin.

JewelSwap's design includes both models. You can read the full mechanics in the JewelSwap money markets documentation, and we break the structures down further in our explainer on isolated and cross lending.

The role of oracles

None of this works without reliable prices. To know your current LTV and whether a position should be liquidated, a protocol needs an accurate, tamper-resistant value for every collateral asset. That job belongs to price oracles. JewelSwap draws on multiple sources, including Pyth Network and the community-owned Umbrella Network, with additional safe-price feeds from AshSwap and xExchange. Several independent sources reduce the chance that a single faulty or manipulated feed triggers unfair liquidations.

CeFi vs DeFi: two ways to borrow

You can get a crypto-backed loan through centralized or decentralized finance, and the trade-offs are real.

CeFi lenders are companies that custody your collateral and lend you fiat or stablecoins. They can offer a familiar, support-backed experience and sometimes lower rates, but you must trust the company to hold your assets and stay solvent. 2026 made that concrete: AscendEX, BitMEX and BitMart all announced wind-downs inside a single month, as covered in why crypto exchanges are closing. Those were orderly, but the outcome was a corporate decision rather than a user right.

DeFi lending is non-custodial. Your collateral sits in an audited smart contract, not a company's balance sheet. The rules are transparent and enforced by code, positions are visible on-chain, and no one needs your identity to let you borrow. The trade-off is that you manage your own position and take on smart-contract and market risk rather than counterparty risk. For a comparison across both models, see our roundup of the best crypto lending platforms in 2026.

The line is blurring. Coinbase's ETH loans are a CeFi front end on the Morpho protocol, so you get exchange-grade onboarding but also on-chain liquidation rules. Read which model you are actually in before you borrow.

Borrowing against Uniswap tokens or LP positions

A related question we see often is whether you can borrow against UNI or a Uniswap liquidity position instead of ETH. Those are different collateral types with different risks: UNI is a volatile governance token with lower borrow limits, and an LP position combines two assets plus impermanent loss. We cover both in our dedicated guide to borrowing against Uniswap and LP tokens.

JewelSwap: the same model, beyond Ethereum

Here is where we are direct with you. JewelSwap does not operate on Ethereum. It is built on MultiversX, Sui and Radix. But the crypto-backed lending model described above is not exclusive to Ethereum, and that is the point. Over-collateralization, LTV, algorithmic interest and liquidation are universal mechanics. JewelSwap implements the same model on non-EVM chains.

Concretely, its lending design has two complementary systems:

• Money markets with both isolated and cross lending on MultiversX. Status as of October 2026: supplying and borrowing in the MultiversX money markets are paused, while repayments continue. We will update this page when that changes; until then, do not plan a new loan around them.
• NFT-collateralized, peer-to-pool lending on MultiversX, where NFTs from verified collections back EGLD loans at up to 50% of the NFT's value, drawn from a shared pool with clear liquidation rules. A 3 EGLD floor supports up to 1.5 EGLD, and a 16-day plan at 4% costs 0.06 EGLD. NFT-collateralized lending is also available on Sui; see how NFT-collateralized lending works on Sui.

For users on MultiversX, Sui or Radix, the lesson of this guide carries over directly: the same LTV, oracle and liquidation maths apply, whatever chain the loan sits on. It fits alongside other strategies we cover in our guide to crypto passive income.

The risks you must respect

• Liquidation risk. A sharp drop in collateral value can trigger liquidation and a penalty. Conservative LTV and active monitoring are your defence.
• Volatility. Borrowing against a volatile asset amplifies both moves. What looks safe in a calm market can become dangerous overnight.
• Smart-contract risk. DeFi replaces counterparty trust with code trust. Audits reduce risk but never eliminate it. Our checklist on how to check a DeFi protocol is safe helps.
• Oracle risk. Faulty or manipulated price feeds can cause bad liquidations. Multi-oracle designs mitigate but do not remove this.
• Collateral-token risk. LSTs and restaking tokens can depeg or, as the 2026 rsETH exploit showed, be minted without backing through a bridge.
• Governance risk. LTVs, thresholds and listings can change by vote or emergency action, as Aave's WETH freeze showed.
• Interest and rate risk. Variable borrow rates can rise, increasing the cost of holding your loan open over time.

None of these should scare you away, but all of them should shape how much you borrow and how closely you watch it. Our guide to crypto risk management covers the discipline in full.

Frequently asked questions

What is an Ethereum-backed loan?

A loan where you pledge ETH or an ETH-based token as collateral and borrow another asset, usually a stablecoin, against it. You reclaim your ETH by repaying the loan plus interest. The same structure applied to any crypto asset is called a crypto-backed loan.

Why do DeFi loans require more collateral than I borrow?

Because on-chain lenders cannot run credit checks or pursue borrowers, they require over-collateralization instead. The surplus protects lenders and absorbs price volatility, which is what makes permissionless, identity-free borrowing possible.

How much can I borrow against ETH?

It depends on the venue. In 2026 Aave V3 on Ethereum allows up to 80.5% LTV on WETH with an 83% liquidation threshold, and Liquity V2 allows up to 90.91% for ETH. Borrowing near those ceilings leaves very little room: at 70% against an 80% threshold, a 12.5% decline triggers liquidation.

What triggers a liquidation?

Liquidation happens when your loan-to-value ratio crosses the protocol's threshold, typically because your collateral fell in value. The protocol then sells collateral to repay the debt, usually with a penalty. Keeping a conservative LTV and adding collateral when markets fall helps you avoid it.

Can I borrow against staked ETH?

Yes. Many protocols accept liquid staking tokens such as wstETH, rETH or cbETH, usually at lower LTVs than plain ETH. The collateral keeps earning staking rewards, but you add depeg and smart-contract risk from the staking token itself.

Do I pay tax when I borrow against ETH?

In many jurisdictions taking a loan is not a disposal, so it does not trigger capital gains tax on its own, while a liquidation that sells your ETH may. Rules differ by country, so check with a tax adviser where you live.

Is DeFi borrowing safer than a CeFi crypto loan?

They carry different risks. DeFi is non-custodial and transparent, removing the counterparty risk of trusting a company with your assets, but it adds smart-contract and self-management risk. CeFi feels more familiar but requires trusting a custodian's solvency and conduct.

Does JewelSwap offer Ethereum-backed loans?

No. JewelSwap operates on MultiversX, Sui and Radix, not Ethereum. Its lending design uses the same crypto-backed model natively on those chains; as of October 2026, supplying and borrowing in the MultiversX money markets are paused.
