A crypto-backed loan lets you borrow one asset, such as a dollar-pegged stablecoin, while pledging cryptocurrency as security. You retain economic exposure to the pledged crypto, but it is encumbered under the lender’s custody or smart-contract rules. If the debt is repaid with interest and fees, the collateral can be released; if its value falls too far, the lender or protocol can sell it.

The exact rate, eligible assets, maximum loan-to-value (LTV), fees, maturity and liquidation process vary by service and jurisdiction. Coinbase’s USDC loan example, enabled by Morpho on Base, is a useful illustration of the mechanics—not a universal set of crypto-lending terms.

What a crypto-backed loan is

In a conventional secured loan, a lender advances cash against property such as a vehicle or house. A crypto-backed loan follows the same basic idea, but the collateral is a digital asset. You deposit eligible cryptocurrency and receive a different asset as debt. In Coinbase’s documented example, eligible customers borrow USD Coin (USDC) against crypto through Morpho on Base, with Coinbase supplying the user interface. The collateral is locked in the arrangement specified by the product until repayment or liquidation.

The borrowed asset is not investment income. Borrowing USDC does not itself create a yield; it creates a liability. In a separate lender-side arrangement, USDC depositors supply funds to lending markets and borrowers’ interest accrues to those lenders. Lenders take protocol, liquidity and bad-debt risks of their own.

Because the loan is overcollateralized, the market value of the crypto pledged normally exceeds the debt. That buffer protects the lender against price movements, but it also means a borrower can lose collateral without ever taking another withdrawal.

How the borrowing process works

  1. Check eligibility and terms. The service determines whether your account, country, collateral asset and requested loan asset are supported. Availability and terms can change, so read the live offer rather than relying on a third-party summary.
  2. Select collateral and amount. You choose an eligible crypto asset and how much to borrow. The platform displays an initial LTV, interest rate, fees and the market’s liquidation LTV (LLTV), if applicable.
  3. Authorize the collateral transfer. Depending on the design, crypto may move into a smart contract, a custodial account or another arrangement described in the agreement. You should understand who controls the assets and what happens if the protocol is paused or compromised.
  4. Receive the loan asset. Once the collateral transaction is confirmed, the borrowed asset is credited or transferred according to the product’s rules. The debt balance begins accruing interest under the selected rate structure.
  5. Monitor the position. Track collateral value, outstanding principal, accrued interest, LTV and the liquidation threshold. A loan that was comfortable when opened can become dangerous after a market drop or simply as interest accumulates.
  6. Repay and release collateral. Repayment must include the balance, accrued interest and any applicable charges. After the debt is fully settled, collateral is returned or unlocked under the product’s terms.

Collateral: what it secures and what can happen to it

Collateral is the crypto pledged to secure repayment. It is not necessarily available for trading or withdrawal while the loan is outstanding. Coinbase’s collateral documentation explains that assets are held according to the applicable product and protocol arrangement; the release process therefore depends on that agreement.

Collateral value is marked against a market price. A volatile asset can lose value quickly, shrinking the buffer protecting the loan. Some products support several collateral assets, but each asset can have a different risk limit and liquidation threshold. A highly volatile token may receive a lower maximum LTV than a more liquid asset.

Read the custody and recovery terms before depositing anything. Questions worth answering include:

  • Is the collateral held by a company, in a smart contract, or through another custodian?
  • Can you withdraw or swap collateral while the loan is open?
  • What happens if a blockchain transaction is delayed or a protocol is paused?
  • Who can liquidate the position, and how is the sale price determined?
  • Are there insurance exclusions, compensation limits or no-loss guarantees? Treat claims of protection as risk reduction, not certainty.

LTV: the number that determines how close you are to liquidation

Loan-to-value is calculated as:

LTV = (outstanding loan principal + accrued unpaid interest) ÷ current collateral value × 100

Coinbase illustrates the arithmetic with $100 borrowed against $1,000 of collateral, which equals 10% LTV. That is an example, not a recommended borrowing level. The numerator rises when you borrow more or interest accrues. The denominator falls when the collateral price declines. Either movement pushes LTV higher, even if you do nothing.

Each Morpho market sets a liquidation LTV (LLTV). Reaching that threshold can allow automatic liquidation. Coinbase’s health material shows example LLTV settings of 86%, 77% and 62.5% for referenced markets. Those percentages are market-specific examples, not universal limits; the applicable collateral asset and market determine the actual threshold.

Change in the position Effect on LTV Why it matters
Borrow more Increases Debt becomes larger relative to collateral.
Interest accrues Increases Unpaid interest is included in the outstanding balance.
Collateral price falls Increases The same debt is measured against a smaller asset value.
Add collateral Decreases The denominator grows, creating more buffer.
Repay principal or interest Decreases The outstanding balance shrinks.

Interest rates, fees and repayment rules

Variable-rate loans

In Coinbase’s example, a variable rate responds to supply and demand in the lending market and accrues against the outstanding balance. The product documentation describes no set term and no minimum payment for these loans, with partial or full repayment allowed. “No minimum payment” does not mean no cost: interest continues to accumulate, and a rising balance can increase LTV.

Fixed-rate loans

A fixed-rate loan has a stated maturity. Coinbase says the full balance must be repaid by that date and that repaying early does not reduce the interest owed. A fixed rate can make the cost more predictable, but the maturity deadline creates a refinancing or repayment obligation.

Processing and platform fees

Coinbase documents a one-time processing fee when taking or increasing a loan. Its published schedule charges 2% on the first $250,000 and 1% on amounts above $250,000. The fee is added to principal, so it also accrues interest. A platform fee may apply in addition. These are Coinbase-specific published terms and can change; use the fee shown in the loan confirmation screen for your account.

Cost or rule Variable example Fixed example
Rate behavior Moves with market supply and demand. Set for the agreed period.
Term No set term stated by Coinbase. Has a maturity date.
Repayment Partial or full repayment allowed. Full repayment required by maturity.
Early repayment Can reduce the balance and future interest. Coinbase says early repayment does not reduce interest owed.
Other charges Processing and possible platform fees; check the live offer.

What liquidation means

Liquidation is the forced sale or transfer of enough collateral to address a loan that has reached its market’s LLTV. A falling collateral price and growing interest can combine to trigger it. The sale may include a liquidation penalty, whose size and application depend on the product and market.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Liquidation is not the same as a voluntary repayment. You may lose the collateral needed to cover the debt, and fast markets can make the final result differ from the price you saw moments earlier. Protocol liquidity, blockchain congestion and failed transactions can affect execution. Coinbase lists collateral volatility, smart-contract vulnerabilities, cyberattacks, protocol liquidity problems and possible liquidation failure among the risks in its borrower and lender materials.

How to lower LTV before the threshold

  • Repay part of the debt. Paying down principal, and any required interest first, reduces the numerator.
  • Add collateral. Additional eligible crypto increases the denominator. Coinbase offers an optional collateral top-up feature in its product, but a top-up can fail or be partial if funds are unavailable, volatility is severe or a technical problem occurs.
  • Borrow less initially. Leaving a wide buffer is more robust than borrowing close to the maximum allowed LTV.
  • Keep liquidity outside the position. You need accessible funds to repay or top up during a rapid decline; funds locked in the same position may not help.

Coinbase’s warning is worth taking literally: Loan protection helps lower liquidation risk, but it is not a guarantee against liquidation. Protection tools can reduce probability, not eliminate market, software or execution risk.

A numerical example of a changing position

Suppose a borrower deposits $10,000 of crypto and borrows $3,000. The opening LTV is 30% before fees and interest. If a 2% processing fee is added to principal, the balance starts at $3,060, making the initial LTV 30.6% before any further interest. If the collateral falls to $7,000 while the balance grows to $3,120, LTV becomes about 44.6% ($3,120 ÷ $7,000). No additional borrowing was required for risk to increase.

This calculation is an illustration, not a forecast or a safe borrowing limit. The real position uses the market’s price feed, the product’s fee treatment and its LLTV. A borrower should model a sharp price decline, rate increases where applicable, blockchain delays and the possibility that a top-up cannot execute.

How to compare crypto-backed loan offers

Do not compare headline interest rates alone. Put each offer on the same checklist:

Comparison point Questions to ask
Loan and collateral assets What can you borrow, and which coins are eligible as collateral?
Custody and protocol Who holds the crypto, which smart contracts are involved, and what happens during an outage?
Maximum LTV and LLTV What is the starting limit, and at what precise LTV can liquidation begin?
Liquidation economics Is there a penalty, auction spread or other sale cost? How are prices and timing determined?
Interest structure Is the rate fixed or variable, how often does it update, and does interest compound?
Fees Are there origination, processing, platform, network, withdrawal or repayment charges?
Repayment terms Is there a maturity, minimum payment, prepayment charge or mandatory full repayment?
Risk controls Can you top up collateral or repay instantly, and what happens if the action fails?
Eligibility and law Is the product available in your jurisdiction and for your account type? What records and tax advice are required?

Borrower risks beyond price volatility

Crypto-backed borrowing concentrates several risks in one transaction. A smart-contract bug can lock or misdirect assets. A cyberattack can compromise infrastructure. Thin market liquidity can make collateral difficult to sell at an expected price. A liquidation engine can fail or execute late during congestion. These risks exist alongside ordinary interest-rate and repayment risk.

Using a different provider does not automatically remove counterparty risk. A centralized service can impose withdrawals, custody or insolvency risks; a decentralized protocol can expose you to code, oracle, governance and liquidity risks. Read the current disclosures for the exact arrangement instead of assuming that “decentralized” means risk-free or that an interface provider guarantees protocol losses.

What lenders should understand

On the other side of a crypto-backed loan, lenders deposit an asset such as USDC into a lending market. Borrowers’ interest may accrue to those depositors, subject to the market’s rules. Lenders do not have a guaranteed bank-style return: collateral can fall below the debt, borrowers can create bad debt, and insufficient liquidity can delay withdrawals. Smart-contract and cyber risks apply to lenders as well as borrowers.

Taxes, location and changing terms

A loan is not automatically tax-free, and collateral treatment can depend on the transaction, asset, country and later sale or liquidation. Coinbase directs customers to keep records and consult a tax professional. The cited product documentation also imposes eligibility restrictions, so availability should never be generalized to every country or account.

Before signing, confirm the live rate, fee, supported collateral, LLTV, liquidation penalty, repayment deadline and custody arrangement shown for your jurisdiction. Product pages can change after you open an account, and a market’s parameters can differ from another market using the same protocol.

Practical pre-borrowing checklist

  • Calculate the opening LTV using the balance after every fee is added.
  • Stress-test the position against a large collateral-price drop and additional interest.
  • Keep repayment or top-up funds readily available outside the pledged collateral.
  • Record the collateral quantity, transaction IDs, interest, fees and repayment dates for tax and personal accounting.
  • Read the liquidation, custody, smart-contract and outage clauses—not just the rate.
  • Borrow only an amount you could repay without selling at a forced price.

Crypto-backed loans can provide liquidity without an immediate voluntary sale of crypto, but that flexibility is exchanged for interest expense, encumbered assets and liquidation risk. The safest interpretation of any advertised loan is the specific contract in front of you: its collateral rules, LTV calculation, fees, maturity and failure procedures determine how it actually works.
