What Are Crypto Loans and How Do They Work?

Learn about crypto loans, how cryptocurrency loans work, types of crypto loans, CeFi vs. DeFi crypto loans, and the benefits and risks of crypto loans in our guide.

Crypto-backed loans let you borrow funds using your existing assets as collateral. Conversely, you can also use your crypto to earn interest by depositing your assets to crypto loan platforms.

The crypto loans market sits at a staggering $73 billion, and that figure is only rising thanks to a shift to decentralized crypto lending platforms following a lack of transparency and toxic collateral from centralized providers.

In our guide, we’re covering everything you need to know about crypto loans, including how they work, types of loans, accessing loans through crypto lending platforms, and more.

What is a crypto loan?

A crypto loan is a financing option where borrowers pledge tokens (like Bitcoin or Ethereum) as collateral to obtain cash or stablecoins, without selling those assets, allowing them to unlock capital while still holding their assets.

There are two main types of crypto loans:

• Collateralized loans: Backed by crypto assets; the lender can liquidate collateral if the value falls below agreed thresholds.

• No-collateral loans: Much rarer, but available via specific models like flash loans in DeFi. These loans are instant, peer-to-peer, and over-collateralized algorithmically.

Both borrowers and lenders may wish to access crypto loans:

• Borrowers: Investors looking for liquidity or leverage without selling positions.

• Lenders: Platforms or individuals earning interest, especially in DeFi with yield-generating lending pools.

How do crypto loans work?

While the mechanics under the hood for crypto lending might vary, at the surface level, all crypto loans work similarly:

1. Deposit collateral: Borrowers lock up crypto as collateral on a given platform.

2. Receive funds: Typically issued in stablecoins or fiat, proportional to the collateral’s value.

3. Repayment: Repaid with interest to unlock collateral, which is returned at this point.

We mention mechanics because there are different types of crypto lenders: CeFi and DeFi.

CeFi loans

With CeFi crypto lending, you interact with a company that custodies your assets and manages risk off-chain. Your crypto goes to the platform’s wallets (often via third-party custodians).

Loan pricing may be fixed or tiered and can include origination fees and loyalty/staking discounts. Collateral valuation relies on internal risk engines that reference exchange prices; margin calls are communicated by email/app, and liquidations are executed by the platform when thresholds are breached, sometimes with limited grace periods or partial liquidations to restore LTV.

DeFi loans

With DeFi crypto lending, the “lender” is a smart contract that holds pooled liquidity. Interest rates are algorithmic and float with utilization: when demand to borrow rises relative to supply, rates increase; when supply is plentiful, rates fall. Collateral is priced using on-chain oracles; your position’s health factor updates block-by-block. If it drops too low, keepers (liquidators) repay part of your debt and receive a liquidation bonus, selling a slice of your collateral automatically.

Specialized mechanics like flash loans exist for more advanced trading strategies, enabling uncollateralized borrowing within a single transaction, but they’re mainly for developers/arbitrageurs.

Types of crypto loans

The types of crypto loans can broadly be broken down into two groups:

• Collateralized crypto loans and crypto loans with no collateral

• CeFi or DeFi loans

Collateralized crypto loans

The vast majority of crypto loans are collateralized, meaning you pledge a given asset to secure a loan. Because crypto is volatile, these loans are typically overcollateralized, so you deposit more value than you borrow.

The key parameter is Loan-to-Value (LTV): the ratio of your loan size to your collateral’s current market value. But there are some other parameters you need to be aware of in practice:

• Max LTV: the highest borrowing level allowed at origination (e.g., 30 - 70% depending on asset and platform).

• Maintenance threshold/health factor: the minimum collateral buffer you must keep as prices move.

• Liquidation threshold: the point at which the platform sells some of your collateral to repay the loan plus a fee.

Borrowers generally opt for collateralized loans as they’re the most accessible and offer liquidity without selling. Similarly, lenders generally opt for collateralized loans because collateral reduces default risk and can be liquidated quickly if needed.

Crypto loans without collateral

When people ask about crypto loans without collateral, they’re usually referring to one of two very different things:

1. DeFi flash loans. These are specialized, programmatic loans that must be borrowed and repaid in a single blockchain transaction. If repayment doesn’t occur atomically, the whole transaction reverts, so the lender’s funds are never at risk (although flash loan attacks do happen).

2. Under- or uncollateralized credit products: A small number of providers issue business or OTC credit lines based on identity, banking relationships, cash flows, or off-chain collateral. In DeFi, experiments like credit delegation and on-chain scoring exist, but they remain niche and often restricted to institutional borrowers.

CeFi vs. DeFi loans

Both CeFi and DeFi deliver the same result: borrow against crypto and repay to unlock it. But the mechanics, risks, and user experience differ.

CeFi loans operate through a company. You deposit assets to the platform’s custody and receive a loan. Rates may be fixed or tiered and can change with loyalty programs or staking. Collateral valuation is handled by internal risk engines that reference exchange prices. If your position breaches limits, the desk liquidates part of your collateral to bring LTV back in range.

CeFi’s strengths are fiat rails (bank wires, cards), a familiar interface, and customer support. The trade-off is counterparty and custody risk: you rely on the firm’s solvency, security, and disclosures. Jurisdictional access and product terms can also vary by country.

Historically, CeFi loan providers have lacked transparency and held toxic collateral, leading to the collapse of multiple platforms like Celsius and Voyager, and the loss of investor funds and confidence. This is largely why DeFi crypto loans have gained significant market share.

DeFi loans run on smart contracts. You connect a self-custody wallet, approve collateral tokens, and borrow directly from on-chain liquidity pools. Interest is algorithmic and floats with utilization (when borrowers outnumber suppliers, rates rise). Collateral prices come from oracles; your position’s health factor updates with each block. If it falls too low, third-party liquidators (keepers) repay part of your debt and receive a liquidation bonus, selling a portion of your collateral instantly.

DeFi’s big advantages are transparency and control: you can verify reserves and parameters on-chain, keep self-custody, and integrate with other protocols. The trade-offs are smart-contract and oracle risk, gas costs, and crypto-only payouts.

Benefits of crypto loans

Crypto loans come with a multitude of benefits for investors:

• Access liquidity without selling crypto: Borrowers unlock cash or stablecoins while keeping exposure to potential upside. Because you don’t dispose of the asset, you avoid missing out if the market rallies during the loan term.

• Potential tax advantages: In many jurisdictions, taking out a loan secured by assets isn’t a taxable event. That means you may defer capital gains until you actually sell the crypto. But always check local rules (in our crypto tax guides) as tax treatment varies by country.

• No credit score required: Most crypto loan platforms rely on collateral value, not credit history. That can make borrowing accessible to people and businesses with thin credit files or non-traditional income.

• Speed and 24/7 availability: Loans can be initiated and funded quickly, often in minutes, because the process is automated (DeFi) or streamlined (CeFi). Markets don’t close, so you can access funds globally, any time.

• Flexible terms and products: Choose your LTV, loan currency (stablecoins or fiat via certain crypto lenders), open-term vs. fixed-term, and sometimes fixed vs. variable rates. Many platforms let you repay early without penalties.

• Keep your portfolio working for you: With some collateral types (e.g., liquid staking tokens on DeFi), you can borrow against assets that continue to accrue yield in the background.

• Programmability and composability: On-chain crypto lending lets advanced users refinance between protocols, automate health-factor alerts, or use tools like flash loans for arbitrage/collateral swaps.

• Global reach: Many services are accessible cross-border, expanding options for users in regions underserved by traditional banks.

Risks of crypto loans

As with all financial investments, crypto loans come with risk, including:

• Liquidation risk: Crypto prices can move fast. If your LTV climbs above the platform’s thresholds, you may face margin calls or automatic liquidation, often with a penalty. Thin liquidity and sharp drops can amplify losses.

• Counterparty and custody risk: Centralized crypto lenders hold your collateral and control liquidation. Insolvency, poor risk management, or hacks can endanger your assets. Read terms regarding rehypothecation, insurance, and how collateral is custodied.

• Smart-contract and oracle risk: Bugs, exploit paths, or faulty price oracles can cause unexpected liquidations or loss of funds in DeFi lending protocols. Even audited protocols carry residual risk; forks and governance changes can also alter risk profiles.

• Interest-rate and utilization risk: On DeFi, variable borrow rates can spike when pool utilization rises; on CeFi, promotional or tiered rates can change. A strategy that works at 5% may fail at 20%, so always stress-test your strategy.

• Liquidity risk: In periods of market stress, lending pools can become illiquid, or centralized lenders can restrict withdrawals. If stablecoin or collateral liquidity dries up, liquidations may execute at poor prices.

• Stablecoin and peg risk: If you borrow or post collateral in stablecoins, a de-peg can affect your effective LTV or repayment cost. Understand each stablecoin’s collateral model and historical behavior.

• Regulatory and jurisdictional uncertainty: Access to cryptocurrency lending can change with new laws, enforcement actions, or licensing requirements.

• Legal recourse limits: In DeFi, “code is law”: disputes are hard to remedy once a transaction settles. In CeFi, your rights depend on the platform’s terms and local law; recoveries in bankruptcy can be uncertain.

Some practical common-sense tips to follow to mitigate crypto loan risk include keeping a conservative LTV, automating margin call or liquidation alerts, and using reputable crypto lending platforms or protocols.

Crypto loans tax

Crypto loans may offer tax benefits, but this all depends on the specific loan product you’re using and where you live.

According to US crypto tax rules, taking out a loan, at least for CeFi loans, generally won’t create a taxable event, as you’re not disposing of your crypto. So, for example, using BTC as collateral to get a cash or stablecoin loan wouldn’t create a taxable event.

Interest expenses may, in some instances, be written off on your tax return, but only if you’ve used your loan proceeds for further investments or other business purposes. If you’ve used your loan for personal expenses, this would not be tax-deductible.

Liquidations are a disposal from a tax perspective and would trigger a Capital Gains Tax event. 

For DeFi loans specifically, as the protocols often work differently from CeFi loans, there may be different tax implications. This is because, in many instances, when you deposit your collateral on a DeFi loan protocol, you’ll receive tokens in return representing said collateral. This may be classed as a taxable crypto-to-crypto trade and therefore a CGT disposal.
