TL;DR
A stablecoin loan lets you borrow USDC, USDT or another dollar stablecoin against crypto collateral, without selling it. The right pick depends on which stablecoin you need, which chain you want it on, and who you trust to hold your collateral.
- Best for USDT and mixed collateral: Nexo. A custodial credit line paying USDT or USDC, against 30+ assets.
- Best for USDC in the US: Coinbase, powered by Morpho. Onchain USDC on Base, from a familiar app.
- Best for self-custody and choice of chain: Aave. USDC, USDT and GHO across many networks, at market rates.
- Best for USDS and DAI: Spark, the Sky ecosystem's lending market.
- Best for BTC holders who want collateral safety: Ledn. Fixed terms, funded in USDC or USDT.
What a stablecoin loan is, and what it is not
A stablecoin loan is a crypto-backed loan where the money you receive is a stablecoin rather than dollars in a bank. You post BTC, ETH or another asset as collateral, borrow USDC, USDT or USDS, and repay in the same stablecoin to release your collateral.
It is the borrower's side of the market. If you want to earn interest by supplying stablecoins, see what is stablecoin lending. If you are open to cash loans paid into a bank account as well, see the wider best crypto loans comparison.
Why borrow a stablecoin instead of dollars? Stablecoins move onchain in minutes, work across borders, and can be used directly in DeFi, for payments or for treasury. Borrowing them avoids a slow off-ramp, and repaying in the same stablecoin generally avoids a taxable disposal, as we explain in are crypto loans taxable.
Borrowing stablecoins against volatile assets is also the core use of DeFi lending: roughly 45% of Aave's borrowing demand comes from users borrowing stablecoins against BTC and ETH, according to an analysis reported by MEXC.
What actually matters when choosing a stablecoin loan
The criteria that separate stablecoin loans are slightly different from cash loans:
- Which stablecoin. USDC, USDT and USDS are not interchangeable. Payment partners, exchanges and regions favor different ones. Our explainer on what is USDT covers the main differences.
- Which chain. A USDC loan on Base is only useful if you can use or bridge USDC on Base. Onchain lenders pay out to a specific network; custodial lenders let you withdraw to supported networks.
- Custody of collateral. Custodial platforms hold your crypto. DeFi protocols hold it in smart contracts.
- Rate type. Variable DeFi rates move with pool utilization. Fixed-term loans lock a rate but cost more.
- Liquidation terms. The gap between your starting LTV and the liquidation threshold decides how much of a price drop you survive. See crypto loan LTV and liquidation explained.
The framing that matters: for a stablecoin loan, the payout is half the product. A cheap loan in the wrong stablecoin, on the wrong chain, costs you bridge fees, swap spreads and time.

Top stablecoin loan options compared
Nexo
What it does well: Nexo is the simplest app-based way to borrow USDT. Its Credit Line lets you borrow between $50 and $2 million against BTC, ETH and 30+ assets, paid out as USDT or USDC, with no fixed repayment schedule, per Nexo. You can draw again after repaying, which suits recurring stablecoin needs such as supplier payments.
Where it breaks: custodial collateral, and pricing tied to loyalty tiers based on holding NEXO tokens. Low headline rates require low LTV and a higher tier. Read the full Nexo review, or open a Nexo account.
Best for: borrowers who need USDT, hold several assets, and want a revolving line.
Coinbase (powered by Morpho)
What it does well: Coinbase is the most accessible onchain USDC loan for US users. Your BTC or ETH becomes collateral in a Morpho market on Base, and USDC lands in your Coinbase account, per Coinbase. Borrowers can go up to 75% LTV, with liquidation at 86%, The Block reported.
Where it breaks: USDC only, a variable rate, and a thin liquidation buffer at high LTV. It is not available to New York residents, and loan proceeds cannot be used to trade on Coinbase.
Best for: US BTC and ETH holders who want USDC with minimal setup.
Aave
What it does well: Aave offers the widest choice of stablecoins and chains. You can borrow USDC, USDT or Aave's own GHO across Ethereum, Base, Arbitrum and other networks, straight to your own wallet. Rates follow a public utilization curve, and governance tunes them actively: in September 2026, the first slope for USDC on Aave v3 Core was raised from 4.30% to 4.40%, per Aave governance.
Where it breaks: you manage your own health factor, carry smart contract and oracle risk, and must wrap BTC before using it. Rates can spike when a stablecoin pool is fully borrowed. Compare custody models in Aave vs Nexo.
Best for: self-custody users who want to choose the stablecoin and the chain.
Spark
What it does well: Spark is the lending market aligned with Sky, the protocol formerly known as MakerDAO. Users borrow USDS, the successor to DAI, against ETH, wstETH and other approved collateral, with a governance-set borrow rate of around 6% to 7% depending on collateral type, per Eco. Because rates are set by governance rather than pure utilization, they tend to be steadier than Aave's.
Where it breaks: USDS and DAI have less exchange and payment-partner support than USDC or USDT. If you need USDC, you will swap, which adds a step. It shares the smart contract and governance risks of any DeFi protocol.
Best for: DeFi users who are happy to hold USDS or DAI and value steadier rates.
Compound v3
What it does well: Compound v3 uses single-asset markets: each market lends one base asset, such as USDC, against a list of collateral. That simplicity makes risk easier to read. Borrowing USDC on Compound v3 on Ethereum cost 4.76% on October 6, 2026, per Panaprium.
Where it breaks: fewer stablecoin and collateral options than Aave, and the same self-managed liquidation risk.
Best for: borrowers who only need USDC and prefer a simpler market structure.
Ledn
What it does well: Ledn funds bitcoin-backed loans in USDC or USDT as well as dollars, with collateral that is never lent out and is legally ring-fenced, per Ledn. Loans start at 50% LTV and liquidate at 80%, the widest buffer here.
Where it breaks: the most expensive option at 9.25% to 11.49% APR, BTC only, and fixed 12-month terms. Read the full Ledn review.
Best for: BTC holders who want a stablecoin loan without handing collateral to a rehypothecating lender.
How to borrow stablecoins: step by step
- Pick the stablecoin and chain you actually need. Check where you will spend or send it.
- Choose custodial or onchain. Custodial suits simplicity and USDT; onchain suits self-custody and chain choice.
- Deposit collateral at a conservative LTV. Work out your liquidation price before you borrow.
- Borrow and move the stablecoins. Send them to a wallet that supports the chain; see our guide to the best USDC wallet.
- Repay in the same stablecoin. This releases your collateral and generally avoids a taxable disposal.
Key differences that actually matter
USDT borrowers have fewer good options. Nexo, Aave and Ledn lend USDT; Coinbase and Compound v3 focus on USDC. If USDT is your working currency, that narrows the field quickly.
Chain choice is an onchain advantage. Aave lets you borrow on the network where you will use the funds, which avoids bridging. Custodial lenders let you withdraw to supported networks, but the loan itself sits on their books.
Rate setting differs by design. Aave and Compound rates float with utilization, Spark's are set by governance, and Ledn's are fixed for the term. Nexo's depend on your tier. Predictability and cost pull in different directions.
When the top picks are not the right choice
- You need dollars in a bank account: a cash lender is simpler. See best crypto loans, which includes Figure.
- You want to mint rather than borrow: opening a Sky vault to mint USDS directly is a related route, with stability fees and liquidation rules of its own.
- You cannot add collateral in a crash: do not borrow, or borrow far below the maximum LTV.
The verdict
For USDT and multi-asset collateral, Nexo is the most practical choice, as long as you keep LTV low. For USDC in the US, Coinbase's Morpho integration is the easiest route. Aave is the default for self-custody and the widest choice of stablecoins and chains, Spark suits borrowers comfortable with USDS, and Compound v3 keeps USDC borrowing simple. Ledn costs the most but offers the strongest collateral protections.
The open question is whether stablecoin loans converge on a few dominant pairs, such as USDC on Base, or stay fragmented across stablecoins and chains. If you are building stablecoin credit products, reach out.
FAQs
What is the best stablecoin loan?
There is no single best stablecoin loan. Nexo suits USDT and mixed collateral, Coinbase via Morpho suits US users who want USDC, Aave suits self-custody users who want a choice of stablecoin and chain, Spark suits USDS borrowers, and Ledn suits BTC holders who prioritize collateral protection.
Can I borrow USDT against bitcoin?
Yes. Nexo pays its Credit Line in USDT or USDC against BTC, Ledn can fund bitcoin-backed loans in USDT, and Aave lets you borrow USDT against wrapped BTC. Coinbase's crypto-backed loans pay out in USDC rather than USDT, so you would need to swap.
Where is the cheapest place to borrow USDC?
DeFi protocols usually offer the lowest variable rates. Borrowing USDC on Aave v3 Ethereum cost about 4.3% in late September 2026, and Compound v3 was 4.76% in early October. Coinbase advertises rates from about 5%. Rates move daily, so compare at the time you borrow.
Are stablecoin loans safe?
They carry the same core risks as any crypto-backed loan: liquidation if collateral falls, custodial risk on platforms like Nexo and Ledn, and smart contract risk on Aave, Spark and Compound. Borrowing at a low LTV and choosing a custody model you understand reduces, but does not remove, those risks.
Do I need to repay a stablecoin loan in the same stablecoin?
Generally yes. Most lenders require repayment in the stablecoin you borrowed, and some custodial lenders also accept other assets. Repaying in the same stablecoin is also the cleanest option for US tax purposes, because it avoids disposing of appreciated crypto.
