What Are Crypto Loans? A Plain Guide to Borrowing Against Crypto

A crypto loan is a loan in which you lock cryptocurrency as collateral and receive money or other tokens in return. You repay the borrowed amount plus interest, and then you get your collateral back. If you fail to repay or your collateral loses too much value, the lender or the protocol can sell some or all of it.

The main appeal is that you can raise cash without selling the asset you are holding. Someone who owns ETH or BTC and wants stablecoins for a few months can borrow against it and keep their exposure to the price, instead of closing the position.

Several features set crypto loans apart from a bank loan:

• Collateral is the credit check. Most lenders do not look at your income or credit history. They look at what you deposit.
• Overcollateralization is the norm. You usually lock more value than you borrow, for example 10,000 dollars of collateral for a 5,000 dollar loan.
• Loans are often in stablecoins. USDC, USDT and similar tokens are common, though some platforms lend fiat or volatile assets as well.
• Liquidation is automatic. There are no collection calls. A rule in code or a risk engine sells collateral when a threshold is crossed.
• Terms can be open-ended. Many DeFi loans have no fixed maturity, and you can repay whenever you like while keeping the position healthy.

Crypto loans come in two broad forms: decentralised (DeFi) loans made through smart contracts, and centralised (CeFi) loans made by a company that holds your collateral. The rest of this guide explains how each works, what can go wrong, and how to judge a platform before using it. Nothing here is financial advice, and borrowing against volatile assets can lead to the loss of your collateral.

The basic flow is similar across platforms, even though the details differ.

1. Choose a collateral asset and a borrow asset. Platforms list which tokens they accept and which they lend out.
2. Deposit collateral. On DeFi, this goes into a smart contract from your own wallet. On a centralised platform, it moves into the firm's custody.
3. Borrow up to a limit. The maximum is set by a loan-to-value (LTV) cap for that collateral. Volatile assets usually get a lower cap than stable ones.
4. Pay interest. Interest accrues continuously or on a schedule, at a variable or fixed rate.
5. Monitor the position. If collateral falls or debt grows, your risk rises.
6. Repay and withdraw. You return the principal plus interest and then reclaim the collateral.

A hypothetical example. Suppose you deposit collateral worth 10,000 dollars and borrow 5,000 dollars of stablecoins. Your LTV is 50 percent. Imagine the platform's liquidation threshold is 80 percent. Liquidation would begin when your collateral falls to about 6,250 dollars, because 5,000 divided by 6,250 is 0.8. That is a fall of 37.5 percent from where you started. These numbers are illustrations only, and real limits vary by asset, platform and market conditions.

In practice, interest also adds to your debt over time, which nudges your LTV upward even if prices do not move. Borrowers who keep a wide safety margin, repay part of the debt in a downturn, or top up collateral have more room to ride out price swings.

Several loan models exist, and each moves risk to a different place. The table summarises the common ones.

Type	Who holds collateral	Identity checks	Typical features
DeFi money market	Smart contract pool	Usually none at protocol level	Variable rates set by supply and demand, open-ended loans, automatic liquidation
Collateralized debt position (CDP)	Smart contract vault	Usually none	You mint a stablecoin against collateral, with fees and liquidation rules set by governance
Fixed-term or peer-matched DeFi	Smart contract	Usually none	Agreed rate and maturity, matched lenders and borrowers
Centralised lender	The company	Typically required	Fixed or variable rates, customer support, collateral held in custody
Exchange margin or borrowing	The exchange	Required	Borrowing against account balances, often tied to trading
Self-repaying or non-liquidatable design	Smart contract	Usually none	Yield on the collateral pays down the debt, with no price-based liquidation, though other trade-offs apply

Not every platform in a category offers every feature, and products change, so read the current documentation before you commit.

Which model fits which goal? Someone who wants control of their own keys may prefer DeFi. Someone who wants a familiar interface, fiat payouts or support staff may prefer a regulated centralised service. Traders sometimes borrow inside an exchange account to fund positions, which carries its own leverage risks. Whichever model you pick, find out who can move your collateral, under what conditions, and what happens in a bad market. That answer tells you more about the risk than the headline interest rate does.

Crypto lending uses a small vocabulary. Knowing these terms makes any platform's dashboard readable.

• Collateral: The assets you lock to secure the loan.
• Principal: The amount you borrowed, before interest.
• LTV (loan-to-value): Debt divided by collateral value. A 50 percent LTV means you owe half the value of what you deposited.
• Maximum LTV: The highest LTV at which you can open or increase a loan.
• Liquidation threshold: The LTV at which your collateral becomes eligible to be sold. It sits above the maximum LTV, which leaves a buffer.
• Health factor: A ratio some protocols show instead of LTV. A value above 1 means safe, and it falls toward 1 as risk rises. Definitions vary, so read how each platform calculates it.
• Liquidation penalty or bonus: An extra charge taken from your collateral, which pays liquidators for stepping in.
• APR and APY: APR is the simple yearly rate. APY includes compounding. Borrow rates in DeFi are often variable and can change block by block.
• Utilisation: The share of a lending pool that is currently borrowed. Higher utilisation tends to push rates up.
• Oracle: A data feed that tells a smart contract the market price of an asset. Loans rely on oracles to know when to liquidate.
• Overcollateralized / undercollateralized: Whether collateral exceeds or falls below the loan value.

Two of these terms cause the most surprises. The first is the gap between maximum LTV and the liquidation threshold: borrowing right at the maximum leaves very little room. The second is variable rates: the rate you see today may not be the rate you pay next month.

A DeFi loan has no loan officer. A smart contract holds collateral, tracks debt, applies interest and enforces liquidation. Lenders deposit assets into a pool, borrowers draw from it, and an interest rate curve adjusts the cost according to how much of the pool is in use.

The parts that matter are:

• Pools and markets. Some protocols use one shared pool per asset. Others use isolated markets, so a problem with one asset does not spread to the rest.
• Oracles. Price feeds decide when a position is unsafe. A faulty or manipulated feed is a known attack route.
• Liquidators. Anyone can repay part of an unhealthy loan and receive collateral at a discount. This keeps the system solvent but costs the borrower.
• Governance and risk curation. Token holders or specialist risk managers set collateral lists, caps and parameters. Firms such as Gauntlet and Steakhouse Financial curate lending vaults and risk settings for other protocols.

Some examples of products in this category: Dolomite is a multi-chain money market for lending, borrowing and leveraged strategies across a very large list of assets. 40 Acres takes a different approach, offering self-repaying, non-liquidatable USDC loans against veNFTs on Base and Avalanche, which suits holders of that specific asset type but has its own mechanics and risks to read first. On the lender side, Lulo is a Solana aggregator that spreads stablecoin deposits across lending protocols.

Because there is no support desk, mistakes such as approving the wrong contract or sending funds to the wrong network are usually irreversible.

Centralised crypto loans work more like a conventional financial product. You sign up, verify your identity, transfer collateral to the company and receive funds into your account. The company sets rates, collateral limits and margin-call rules, and it can change them under its terms of service.

People choose this route for convenience: fiat on and off ramps, customer support, fixed rates in some cases, and no need to manage a self-custody wallet. Exchanges in this category, such as OKX, Gate and Bitget, offer trading, earn and margin products, and some platforms add borrowing features. Backpack combines an exchange, a wallet and cross-collateral margin. Bitvavo is a MiCA-authorized exchange serving European users. Product lists, supported countries and eligibility differ for each, so check what is available to you before assuming a given service offers loans.

The key trade-off is custody. Once collateral leaves your wallet, you hold a claim on the company rather than the assets themselves. In 2022, several large crypto lenders, including Celsius, BlockFi and Voyager, froze withdrawals and filed for bankruptcy, and customers became unsecured creditors. The firms had been reusing deposits in ways customers had not fully understood.

Questions to ask a centralised lender:

• Does it reuse or lend out your collateral?
• Where is it held, and is it segregated from company funds?
• Which regulator supervises it, and what protections apply where you live?
• How and when does it liquidate, and does it warn you first?

Proof-of-reserves reports show some assets but rarely show every liability, so they are not a full guarantee.

People borrow against crypto for a handful of recurring reasons:

• Liquidity without selling. You can cover an expense or opportunity while keeping your long-term holding.
• Possible tax timing. In some jurisdictions, borrowing is not treated as a disposal, while selling is. This is not universal, and liquidations or swaps may still be taxable, so speak to a qualified adviser.
• Leverage. Borrowed stablecoins can buy more of the same asset, which magnifies both gains and losses. This is the riskiest use.
• Hedging or funding. Traders may borrow one asset to short it or to fund positions on another venue.
• Short-term cash flow. Some businesses and individuals use crypto-backed credit instead of converting holdings.

Borrowing versus selling. Selling ends your market risk and your exposure. Borrowing keeps both, and adds interest cost, liquidation risk and the effort of monitoring a position. If you would be comfortable holding cash instead of the asset, selling may be simpler. If you have strong reasons to keep the asset and you can keep a conservative LTV, borrowing can make sense.

Who should be cautious. Crypto-backed loans are not a good fit for anyone who cannot tolerate losing the collateral, who borrows to fund essential spending, or who plans to run an LTV near the limit. Prices can fall sharply within hours, sometimes faster than a person can react, and an automatic liquidation may happen while you are asleep. Keep spare funds or a plan to top up collateral in case of a downturn.

The risks differ by loan type, but these are the main ones.

Liquidation risk. A sharp fall in collateral value can trigger a forced sale, often with a penalty. The risk is greatest when you borrow volatile tokens against other volatile tokens, because both can move at once.

Smart-contract risk. A bug or exploit in a DeFi protocol can drain funds. Audits reduce this risk but do not remove it, and code that has been live for longer with large value locked has generally been tested more.

Oracle and market risk. Bad price data or thin markets can cause unfair liquidations or leave a protocol with bad debt. Collateral that trades in low volume is more exposed.

Counterparty risk. With a centralised lender, you rely on the firm staying solvent and honouring withdrawals. The 2022 lender collapses are the clearest example.

Stablecoin risk. If the stablecoin you borrowed or hold as collateral loses its peg, your position can change quickly.

Interest rate risk. Variable rates can spike when pool utilisation rises, making a loan more expensive than planned.

Operational and security risk. Phishing sites, fake approvals and compromised wallets are common routes to loss. Signing a malicious transaction can hand over collateral.

Regulatory and tax risk. Rules for crypto lending vary by country and change over time. A product may be restricted where you live, or treated differently for tax than you expected.

None of these can be eliminated. They can be managed with conservative LTVs, diversified venues, small test amounts, and a clear plan for what you will do if the market moves against you.

A careful comparison looks at more than the headline rate. A useful checklist:

• Custody and control. Who can move your collateral? Is it in your wallet, a contract, or the company's accounts?
• Collateral and borrow list. Does it support the assets you hold, and what LTV and liquidation thresholds apply to each?
• Liquidation rules. Is it full or partial, what is the penalty, and are warnings provided?
• Rate structure. Variable or fixed, any origination or withdrawal fees, and how the rate is calculated.
• Security record. Look for published audits, a bug bounty, a history without major exploits and clear incident disclosures.
• Governance and risk management. Who sets parameters, and are changes transparent? Independent risk managers may be named in the documentation.
• Transparency. Public dashboards, documentation and, for centralised firms, clear terms and regulatory status.
• Eligibility. Confirm that the service is available where you live and that you meet its age and identity requirements. Do not try to get around restrictions or identity checks, because doing so can lead to frozen funds and breaches of the terms.

Defensive habits. Use the official website or app only, and bookmark it. Check the contract address and network before approving anything. Prefer a hardware wallet for significant collateral. Keep token approvals limited and revoke those you no longer need. Treat unsolicited messages offering loans or support as scams. Rates, collateral lists and supported regions change often, so check each platform's own live pages rather than relying on any article.

If you decide to borrow, a cautious process looks like this.

1. Set a purpose and a limit. Decide why you are borrowing and how much loss you could accept. Do not borrow money you need for essentials.
2. Pick a conservative LTV. Many users stay well below the maximum to leave a buffer against a sharp fall. Your own risk tolerance should decide the number.
3. Choose the platform type. Weigh self-custody and smart-contract risk against custodial and counterparty risk.
4. Start with a small test. Deposit a small amount, borrow a little, repay it, and withdraw. This confirms that you understand the interface, fees and network.
5. Read the terms. Check liquidation rules, rate type, fees, and what the platform may do with your collateral.
6. Set up monitoring. Use the platform's alerts or a portfolio tracker, and keep funds or spare collateral available to respond.
7. Plan your exit. Know how you will repay: from income, from selling part of the collateral, or by refinancing. Remember that refinancing depends on market conditions at that time.
8. Keep records. Note deposits, borrows, interest and liquidations for tax reporting, and speak to a local adviser if you are unsure of the treatment.

Where to check current information. Live rates, collateral limits, total value locked and incident history change continuously. Check each protocol's own app and documentation, public lending-market analytics dashboards, and published audit reports. For centralised services, read the current terms, supported-country list and regulatory disclosures on the provider's own site before depositing anything.
