Crypto loans let you borrow cash or stablecoins by depositing cryptocurrency as collateral. A crypto-backed loan works like a secured loan. You lock BTC, ETH, or stablecoins such as USDT, borrow a portion of their value (usually 30% to 80%), pay interest, and get your collateral back when you repay. There is no credit check. If your collateral falls too far in value, it can be liquidated to cover the debt. You keep exposure to your assets while accessing liquidity. The lending market hit $73.59 billion by the end of Q3 2025, surpassing the previous peak from 2021.
Bitcoin-backed loans are the most common type. Instead of selling BTC and giving up long-term upside, you use it as collateral, borrow stablecoins, and stay fully exposed to Bitcoin. If you do not hold Bitcoin yet, you can buy BTC first and then use it as collateral.
This guide explains how crypto loans work, what collateral types are accepted, practical use cases for Bitcoin-backed loans, and how to evaluate different lending platforms.
How Do Crypto Loans Work?
The mechanics are straightforward. You deposit cryptocurrency into a lending platform. The platform assigns a value to your collateral based on current market prices. You receive a loan, typically in stablecoins like USDC or USDT.
Throughout the loan term, you pay interest on the borrowed amount. Your collateral remains locked until you repay. If your collateral value drops below a certain threshold, the platform liquidates some or all of it to cover the debt.
How to Get a Crypto-Backed Loan, Step by Step
Choose a platform type: a centralized exchange, a DeFi protocol, or a native lending protocol.
Deposit your collateral, such as BTC, ETH, or USDT.
Pick a loan amount below the maximum LTV, leaving a buffer before the liquidation threshold.
Receive the loan, usually in USDC or USDT.
Monitor your LTV. If prices fall, add collateral or repay part of the loan.
Repay the principal plus interest and withdraw your collateral.
Crypto Loans vs Traditional Loans
A loan for cryptocurrency collateral differs from a bank loan in a few ways. There is no credit check or income verification, because the collateral secures the debt. Funds usually arrive in minutes rather than days. Many platforms, especially DeFi protocols, have no fixed repayment schedule. The trade-off is that loans are overcollateralized, and a falling market can put your collateral at risk of liquidation.
Collateral Types Accepted
Bitcoin and Ethereum remain the most widely accepted collateral assets. They offer deep liquidity and relatively stable price floors compared to smaller tokens. Most platforms also accept stablecoins as collateral. Because USDT and USDC hold a steady dollar value, they often qualify for the highest LTVs. Borrowing against USDT is a common way to access another asset, or a different stablecoin, without selling your position.
Some DeFi protocols accept a broader range of tokens, including governance tokens and liquid staking derivatives. The trade-off is usually higher interest rates and lower loan-to-value ratios for these riskier assets.
LTV Ratios Explained
Loan-to-value ratio determines how much you can borrow relative to your collateral. Industry standard ranges from 30% to 70% LTV, with initial LTVs commonly falling in the 30-60% range and liquidation thresholds between 70-80%.
A 50% LTV means depositing $10,000 in Bitcoin lets you borrow $5,000. The gap between your initial LTV and liquidation threshold is your safety buffer. Higher initial LTVs mean less room before liquidation triggers.
Platforms set LTV limits based on collateral volatility. Bitcoin typically qualifies for higher LTVs than smaller altcoins. Stablecoin collateral often allows the highest ratios since price risk is minimal.
Interest Rate Structures
Crypto loan interest rates vary significantly across platforms and market conditions. Centralized exchanges often offer fixed rates, making repayment predictable. DeFi protocols typically use variable rates that fluctuate with supply and demand.
Rates depend on several factors: collateral type, loan duration, platform utilization, and overall market conditions. Bitcoin collateral generally commands better rates than volatile altcoins. Chainflip's native BTC lending uses a variable rate that moves with pool utilization, so check the current APR in the lending app before you borrow.
Variable rate protocols can see rates spike during high demand periods. Fixed rate offerings provide certainty but may cost more during normal market conditions.
Liquidation Mechanics
Liquidation protects lenders when collateral values fall. If your collateral drops and your LTV exceeds the liquidation threshold, the platform sells your assets to recover the loan amount.
Traditional liquidation is binary. Once triggered, your entire position or a significant portion gets sold at market prices. This can result in losses beyond what was strictly necessary to cover the debt, especially during volatile markets.
Some protocols now implement soft liquidation, which gradually rebalances your position rather than forcing a sudden sale. Chainflip uses this approach for its native BTC lending, converting collateral incrementally to reduce your debt while preserving more of your position.
Common Use Cases for Bitcoin-Backed Loans
Cover Expenses Without Selling BTC
This is the most common use case. You borrow stablecoins against BTC and use them for rent, bills, unexpected expenses, travel, or short-term cash needs. Your Bitcoin stays locked as collateral while the loan is active. You repay the loan and reclaim your BTC.
Tax Deferral
Selling crypto triggers capital gains taxes in most jurisdictions. Borrowing against your holdings lets you access liquidity without creating a taxable event. The IRS and most tax authorities treat loans differently than sales.
Hold Stable Liquidity While Staying Long BTC
Many BTC holders want Bitcoin exposure plus stable liquidity on the side. A BTC-backed stablecoin loan lets you deposit BTC collateral, borrow USDC or USDT, and hold liquidity while Bitcoin continues to move.
Fund a Business Without Touching Your Portfolio
BTC-backed loans work like a collateralized credit line. You hold BTC long-term, need capital for a business expense, borrow stablecoins short-term, and repay over time. This is useful if you would otherwise be forced to sell Bitcoin into a weak market.
Buy Time During Volatility
True BTC holders do not sell because they want to. They sell because they have to. A Bitcoin-backed loan can act as a pressure-release valve when the market is down, liquidity is needed immediately, and selling feels like the worst timing possible. Instead of selling BTC, you borrow against it, solve the immediate liquidity need, and repay later.
Deploy Capital Into Opportunities
Some users borrow stablecoins against BTC and deploy them into other assets, hedges, yield strategies, or diversification. This is the productive BTC collateral use case. Risk increases here, so manage your LTV carefully.
Leverage
Some borrowers use loan proceeds to buy more crypto, amplifying their exposure. This strategy works well in rising markets but compounds losses when prices fall. For a detailed breakdown of this approach, see our guide on using BTC loans to buy more Bitcoin.
CEX vs DeFi vs Native Lending Platforms
Centralized Exchange Lending
Platforms like Nexo, BlockFi (historically), and exchange-native lending products offer familiar interfaces and customer support. The trade-off is custody risk. Your collateral sits in the exchange's wallets, subject to their solvency and security practices.
DeFi Lending Protocols
Aave and Compound dominate onchain lending, with Compound holding $1.8 billion TVL as of May 2026. These protocols let you borrow against wrapped tokens like wBTC without intermediaries. Smart contracts handle everything.
The limitation is asset compatibility. Bitcoin users must first wrap their BTC into an ERC-20 token, introducing bridge risk and additional complexity. Onchain lending now holds 66.9% market share, reflecting growing comfort with DeFi protocols.
Native Bitcoin Lending
Native protocols like Chainflip eliminate the need for wrapped assets entirely. You deposit actual Bitcoin and borrow against it directly. No bridges, no wrapping, no ERC-20 conversions. The protocol's validators secure your collateral through a decentralized custody model rather than a centralized custodian.
For a detailed comparison of how native lending differs from wrapped asset protocols, see our breakdown of native vs wrapped lending on Chainflip, Aave, and Compound.
Why Native BTC Lending Matters
Wrapped BTC is not BTC. It is a representation of BTC that depends on counterparties, issuers, custody arrangements, and extra layers of infrastructure.
Wrapping BTC introduces risks: custodians can fail, bridges can be exploited, and smart contract complexity adds attack surface. That may be acceptable for some users, but a growing number are looking for Bitcoin lending without wrapped tokens.
Native BTC lending lets you access DeFi with Bitcoin without wrapping. Chainflip is built around native cross-chain utility, enabling Bitcoin to be used without becoming a synthetic ERC-20 token first.
What to Consider Before Borrowing
Evaluate liquidation risk carefully. How much buffer exists between your initial LTV and the liquidation threshold? What would a 30% or 50% price drop do to your position?
Understand the custody model. Who controls your collateral? Is it a centralized entity, a smart contract, or a validator network?
Compare total costs. Interest rates matter, but so do gas fees, withdrawal fees, and any platform-specific charges. Native protocols often reduce these costs by eliminating bridge and wrapping fees.

FAQ
How do crypto loans work?
You deposit crypto as collateral, borrow a share of its value (usually in USDC or USDT), and pay interest until you repay. When the loan is repaid, you withdraw your collateral. If the collateral value falls and your LTV passes the liquidation threshold, part or all of it is sold to cover the debt.
Do crypto loans require a credit check?
Usually not. The collateral secures the loan, so DeFi and native lending protocols do not check credit or income. Some centralized platforms require identity verification.
Can I borrow against USDT?
Yes. Many platforms accept USDT and other stablecoins as collateral. Because their price is stable, they often qualify for higher LTVs than volatile assets like BTC or ETH.
What is a crypto-backed loan?
A crypto-backed loan lets you borrow cash or stablecoins by depositing cryptocurrency as collateral. You maintain exposure to your assets while accessing liquidity. If your collateral value drops below a certain threshold, the platform liquidates it to cover the debt.
What LTV can I get on a Bitcoin-backed loan?
Most platforms offer 30% to 70% LTV for Bitcoin-backed loans. Initial LTVs commonly fall in the 30-60% range, with liquidation thresholds between 70-80%. Chainflip offers up to 80% maximum LTV for native BTC lending.
How is DeFi lending different from CEX lending?
DeFi protocols like Aave and Compound use smart contracts rather than centralized custodians. You interact directly with the protocol. CEX lending is simpler but requires trusting the exchange with your collateral. Native lending platforms like Chainflip use decentralized validator networks to secure collateral.
What happens if my collateral gets liquidated?
Traditional liquidation sells your collateral at market prices to repay the debt. This can happen suddenly during volatile markets. Some protocols use soft liquidation, which gradually rebalances your position to reduce debt while preserving more of your collateral.
Can I borrow against Bitcoin without wrapping it?
Yes. Native lending protocols like Chainflip let you deposit actual Bitcoin and borrow against it directly. No bridges or wrapped tokens required. Your BTC stays on Bitcoin, secured by validators through a decentralized custody model.
What can you use a Bitcoin-backed loan for?
Stable liquidity, covering expenses, business funding, deploying capital into opportunities, DeFi access, and holding BTC exposure while unlocking capital. Some users also use loans to buy more Bitcoin, though this increases risk.
