What Is Crypto Lending and How Do Crypto Loans Work?

Crypto lending covers two things. You can borrow against the crypto you hold, pledging it as collateral so you keep your position instead of selling it while you free up liquidity, or you can lend your crypto to others and earn interest on it. In each of these cases, the loan will be overcollateralized, meaning there will be more cryptocurrency used in the loan than actually released through it.

Another choice you have is liquidating your crypto. This provides you with capital gains but closes your long-term position.

The majority of this trading takes place with assets like Bitcoin and stablecoins, which work through centralized entities (CeFi) or decentralized platforms (DeFi). The two differ on ownership: CeFi takes your assets onto its books, while DeFi and non-custodial lending leave you holding your position on-chain. In either case, the main risk lies with the collateral; if its valuation falls below the platform’s threshold, it gets liquidated to repay the loan.

What Is Crypto Lending?

Crypto lending is a service that links lenders and borrowers: one side lends out digital assets to earn a return, and the other borrows against crypto it would rather not sell. It works like a standard secured loan: you keep ownership of your collateral until you repay it.

Lenders deposit coins to earn interest on crypto they planned to hold for the long term, so the yield is extra return on a position they meant to keep. Borrowers, on the other side, pledge crypto as collateral to get cash or stablecoins, then repay on their own schedule.

The crypto lending platform acts as an intermediary between the borrowers and lenders. It decides on the assets to be accepted, the borrowing limits that can be placed against them, and the rules for liquidation that apply when your collateral falls to the threshold.

At their core, the two models work very differently. In practice, this difference comes down to custody and risk: on CeFi platforms, the assets are held and there is identity verification, thus exposing you to the insolvency of the company, while in DeFi, you remain the on-chain owner but the risk is of smart-contract bugs.

Either way, you get to borrow against your crypto or earn on it, and the real difference just comes down to who you have to trust. With CeFi, you are trusting a company to stay solvent and act honestly. With DeFi, you are trusting code that runs out in the open, where anyone can read it.

How Do Crypto Loans Work?

So, at its most basic, a crypto loan works like this: you lock up crypto as collateral, you are lent a smaller amount against that crypto, pay interest over time, and get the collateral back once you have repaid the loan, all without having to sell the crypto.

This is where it differs from a bank loan. A bank checks your income, your credit history, and the debts you already carry. A crypto loan looks only at your collateral, so the funds can arrive in minutes rather than the week a loan officer would take.

Borrowing Against Your Crypto: Step by Step

How to borrow against crypto: the basic steps are pretty much the same across most platforms.

• Provide collateral by putting whatever the platform accepts, like Bitcoin or Ether, into its smart contract or custodial wallet.
• Open the loan, and the platform works out your borrowing limit and sends out the proceeds as cash or stablecoins.
• Use the funds or just leave them untouched, since your collateral stays where it is either way.
• Repay part or all of the balance, with interest, and the platform releases your collateral back to you.

On a crypto-backed credit line, those steps happen automatically as you spend. With XPlace Credit Mode, card spending is backed by a credit line secured by on-chain collateral. Supported assets can be used as collateral instead of being sold upfront, so you can access liquidity while keeping your crypto position.

Loan-to-Value (LTV) and Overcollateralization

The loan-to-value (LTV) ratio expresses the relation between the loan amount and its collateral value in percentage terms. For example, if you were to deposit $10,000 worth of BTC and borrow $2,000 from your lender, your LTV would be 20 percent; hence, the smaller the ratio, the higher the buffer before liquidation.

Crypto loans are therefore overcollateralized since the collateral value has to exceed the loan value in order to provide some protection against market fluctuations before any losses occur.

Maximum LTVs vary according to the volatility of assets and platform rules, with most of the platforms capping LTV between 50 and 75 percent and holding the more volatile assets to a lower percentage, while some allow higher.

What Happens if Your Collateral Drops in Value?

The value of your collateral may decrease, even if the amount of your loan is stable. As a result, your LTV increases automatically. When you have a Bitcoin worth $10,000 and the price falls to $8,000 and your loan is still $2,000, your LTV will increase from 20% to 25%. Go above the cutoff point of the platform, and it automatically liquidates part of your collateral to restore the required ratio.

And this forced sale is what liquidation is, and that is the one big risk you take when you borrow against crypto. In most cases, however, you’ll know when it is happening, leaving you enough time to either increase your collateral, repay the loan or reduce your exposure to it. There are some cases where there is liquidation protection and it will alert you of when you are nearing your limit. It improves your chances, but does not remove it, since the risk is inherent in the nature of collateralized loans.

How Does Crypto Lending Work for Lenders?

A lender deposits assets, the platform or protocol lends them out, and part of the interest borrowers pay flows back as yield on crypto that would otherwise just sit there. The way that yield reaches the lender is what separates CeFi from DeFi.

Centralised (CeFi) Lending Platforms

Lending through a CeFi platform hands the whole operation over to a company. It takes in your deposit, lends it out, and pays you interest, which leaves you sitting with counterparty risk, because the firm has to stay solvent and give your assets back the day you ask for them. A few large, better-regulated firms dominate the market, and the ones that came through rely on full collateralisation and transparent reporting. Galaxy Research ranked Tether, Nexo, and Galaxy as the leaders in centralized finance lending for Q3 2025.

Decentralised (DeFi) Lending Protocols

On a DeFi protocol, smart contracts handle the lending. They price each loan by supply and demand and run liquidations automatically, around the clock. At the same time, the ownership stays with you on-chain, eliminating any risk of company failures that made a lot of CeFi lenders fail. What comes instead is the smart contract risk, as even audited code can contain errors; audits only make it less likely but do not guarantee there will be none. Kamino rules on Solana, while Aave and Compound rule on Ethereum.

How Interest and Returns Are Generated

All of the interest comes from the borrowers themselves: they pay interest on the borrowed funds, the platform charges their fees, and the remainder is distributed among the lenders providing the capital. High demand for borrowing increases rates, while low demand leads to them going down. Lending stablecoins represents the clearest example of such dynamics, as recently the rates have been hovering somewhere around the mid-single digits and responding to changes in demand. However, nothing is set in stone here, as the returns generated by the market are always fluctuating.

How to Lend Bitcoin and Other Crypto in Practice

Here is how to lend crypto without the common beginner mistakes, in order. First, decide how much you are willing to risk. Then choose a lending model that fits your risk tolerance. From there, it all becomes an easy process:

• Lend on a regulatory-based CeFi platform or on a DeFi platform, taking into account security, auditing, supported cryptocurrencies, and experience.
• Perform your due diligence by ensuring that your coin has been listed, regardless of whether it is Bitcoin, Ethereum, or any stablecoins.
• Go through the terms and conditions in detail and learn about variable rates, withdrawal policies, and lock-up periods.
• Keep an eye on the position and what it is earning, and generate yield from your crypto on your own terms, withdrawing when liquidity allows.

Knowing how to lend Bitcoin comes with one catch. Bitcoin does not run on smart-contract chains, so before it can act as collateral or earn yield, most platforms wrap it first into a token like cbBTC. Check how a given platform handles that wrapping before you send anything over.

Why People Use Crypto Loans and Crypto Lending

People usually prefer borrowing as opposed to selling for one simple reason: they want to retain the asset. Selling to raise cash means giving up the position along with any gain that might show up later. Borrowing, however, keeps the asset at your end while you can spend it.

None of this is new. The rich have for generations been borrowing against their assets rather than selling, and private banking was built on that very practice. Crypto just brings the same idea to a new asset.

Also, the tax angle should be considered. For the most part, crypto is regarded as property. This was stated by the IRS in its Notice 2014-21. Thus, selling can result in capital gains being incurred while borrowing against it is not considered a disposal. There are two important things to note: first, a liquidation is taxable, secondly, repaying debt through the use of crypto whose value has risen is also taxable.

Selling crypto to spend is generally a taxable disposal; borrowing against it is not a sale. Tax treatment depends on your country and circumstances. Not tax advice.

For lenders, the appeal is obvious – the yield. Crypto you plan to hold for years can earn while it sits there, and in a non-custodial setup a single deposit does two jobs at once: it earns yield and it backs your credit line.

Main Risks of Crypto Lending and Crypto Loans

Crypto lending carries real risk, and each of these is a cost that comes along with the convenience.

• Liquidation. Occurs when your collateral decreases and your loan to value ratio breaches the liquidation limit. The platform will sell your collateral, normally during the most unfavorable timing. Having a lower LTV keeps you farther away from the danger zone.
• Platform and custody. When you hand your funds to a custodial CeFi platform, you are essentially betting on the company staying in business, and that bet went very badly wrong in 2022. Celsius froze withdrawals in July, while Voyager and BlockFi both fell into bankruptcy during that same year, and Genesis filed in January 2023. Depositors ended up ranking as unsecured creditors, way down the queue, and billions of dollars in customer assets got caught up in it.
• Smart contracts. DeFi is built on code, and code tends to wear out over time; therefore, audits mitigate, but don’t negate the risk.
• Volatility. Cryptocurrency is a fast-paced environment, and a daily change of 10 to 20 percent can easily put you into margin calls in less than an hour.
• Regulation. Regulations are yet to be developed in different countries, so what is available in one country may simply not be available in the other one.

The vast majority of losses come from the same root cause: either you borrow too aggressively against an asset that fluctuates, or you put too much trust into a platform that can fail. This is a classic solution, but it works: stay well under your borrowing limit, and use only independently audited or non-custodial platforms.

Conclusion

Crypto lending lets long-term investors put the value of their assets to work without selling them. The borrower keeps the asset and takes out a crypto loan against it, while the lender does the opposite and deposits cryptocurrency to earn interest. Collateral secures the loan, and the LTV helps you know how close you are to being liquidated.

The move itself is an old one. Private banking has allowed individuals to borrow against their assets for decades instead of selling. And what crypto changed is really the speed and the reach. On non-custodial platforms, you keep ownership even while you borrow against your crypto or earn on the same assets.

Clear up some things for yourself before you even put some crypto to work. 1) How much will I have to borrow before a common drop becomes harmful? 2) Is the platform audited, and who has access to the keys, me or them? 3) In case of a massive sell off, what really happens to my collateral?

And that is what XPlace is all about. You can borrow against your crypto without having to sell anything, you can earn yields from your crypto while borrowing, and you stay non-custodial throughout: your funds stay in your own wallet, or in audited smart contracts when you borrow. Never held by us. 

Yield is variable and not guaranteed. Withdrawals depend on protocol liquidity and may be temporarily limited during market stress. Past performance does not predict future results. Using assets as collateral exposes you to liquidation risk. You may lose your collateral if the market moves against your position.
