Crypto Borrowing Platforms: Rates, Collateral, and Terms Compared

Crypto Borrowing Platform Overview

Crypto borrowing lets you access liquidity against your digital assets without selling them. Instead of triggering a taxable event by converting BTC or ETH to dollars, you deposit crypto as collateral and receive a loan in fiat or stablecoins. The total crypto lending market surpassed $73 billion in outstanding loans in Q3 2025, exceeding the previous all-time high set during the 2021 bull market.

Platforms differ significantly in rates, custody models, collateral requirements, and liquidation mechanics. This guide compares the major CeFi and DeFi borrowing platforms so you can evaluate them side by side.

Rates shown are approximate as of mid-2026. DeFi rates are variable and change with pool utilization. CeFi rates may depend on loyalty tiers, loan size, or promotional periods. For a comparison focused on the lending (earn) side, see our crypto lending platform comparison.

CeFi vs DeFi Borrowing

The most fundamental choice in crypto borrowing is between centralized finance (CeFi) and decentralized finance (DeFi). Each model carries distinct risks and tradeoffs.

CeFi platforms operate like traditional lenders: you deposit collateral with the company, complete KYC verification, and receive a loan in fiat or stablecoins. The platform manages custody, sets fixed rates, and handles liquidations internally. CeFi loans can disburse directly to a bank account, and some offer margin calls before liquidation. The tradeoff is counterparty risk: if the platform becomes insolvent, your collateral may be lost.

DeFi platforms use lending protocols governed by smart contracts. There is no KYC, no application process, and no single entity holding your funds. You connect a wallet, deposit collateral into a contract, and borrow against it instantly. Rates adjust algorithmically based on pool utilization. The tradeoff is smart contract risk: bugs, oracle failures, or governance attacks can result in loss of funds. Liquidations are automated with no warning period.

The CeFi lending collapses of 2022 demonstrated how severe counterparty risk can be. Celsius, BlockFi, and Voyager all filed for bankruptcy within months of each other, collectively affecting billions in customer deposits. Celsius was found to have a $1.2 billion deficit. These failures pushed the industry toward stricter custody practices: Ledn now publishes monthly proof-of-reserves data and does not rehypothecate collateral, while Unchained uses a 2-of-3 multisig model where no single party can unilaterally move funds.

DeFi Platform Deep Dive

Aave

Aave is the largest DeFi lending protocol with over $14.6 billion in TVL as of mid-2026. Aave V4 launched on Ethereum mainnet with a hub-and-spoke architecture (Core, Plus, and Prime hubs across eleven spokes). Borrowers deposit collateral and draw loans at variable rates that adjust with utilization. Current stablecoin borrow rates sit around 3%–4.3% APY, while ETH borrowing runs around 1.9%.

Aave's risk parameters are set per asset through governance: ETH has an 80.5% max LTV with an 83% liquidation threshold and roughly 5% liquidation penalty. WBTC carries a 73% max LTV and 78% liquidation threshold. USDT is restricted to Isolation Mode due to centralization concerns.

Compound

Compound V3 uses a single-base-asset model: each market (called a Comet) designates one borrowable asset (typically USDC or WETH), and users supply other tokens as collateral. This simplifies risk management compared to Compound V2's shared-pool approach. TVL stands at approximately $1.8 billion.

ETH collateral in the USDC market carries roughly 83% borrow collateral factor and 90% liquidation collateral factor. Liquidation penalties range from 5%–10% depending on the asset. Compound is available on Ethereum, Polygon, Base, Arbitrum, and Ronin.

Sky (formerly MakerDAO)

Sky Protocol, the rebrand of MakerDAO, operates the largest crypto-backed stablecoin system. Users can borrow USDS (or legacy DAI) by depositing collateral into vaults or through Spark, Sky's aligned lending market. Spark holds $3.2 billion in TVL with an additional $5.6 billion in Sky Lending.

Vault-based borrowing requires overcollateralization at 145%–175% depending on vault type. Spark lending uses parameters closer to Aave: 75% LTV for USDC collateral, 74% for cbBTC. The Sky Savings Rate (SSR) is currently 3.75%, set by governance.

CeFi Platform Deep Dive

Ledn

Ledn specializes in Bitcoin-only lending. Rates range from 9.99% to 11.49% APR on fixed 12-month terms, with tiered pricing down to 9.25% for loans above $1 million. Maximum LTV is 50%, with automatic liquidation triggered at 80% LTV. Loans range from $500 to $1 million.

Custody is handled through BitGo with $100 million in Lloyd's syndicate insurance on cold storage. Ledn does not rehypothecate collateral and publishes biannual proof-of-reserves attestations from The Network Firm LLP. The platform processed over $1 billion in loans during the first three quarters of 2025.

Nexo

Nexo offers instant credit lines against 100+ supported assets with no fixed repayment dates. Standard rates range from 10.9% to 17.9% depending on loyalty tier (determined by NEXO token holdings). Gold and Platinum tiers can access reduced rates as low as 1.9%–3.9% on select credit lines.

LTV varies by asset: BTC and ETH get 50%, stablecoins get up to 90%, and more volatile altcoins are capped at 30%–33%. Liquidation triggers at approximately 83.33% LTV through automatic partial repayment. Nexo relaunched in the United States in February 2026, though it received a $500,000 fine from California's DFPI for licensing violations.

Unchained

Unchained is designed for high-value, Bitcoin-only business borrowers. Rates run 14%–16.21% APR on terms of 3 to 60 months. The minimum loan amount is $150,000, reflecting its institutional focus. Maximum LTV is 50%.

The key differentiator is Unchained's collaborative custody model: collateral sits in a 2-of-3 multisig vault where the borrower holds one key, Unchained holds one, and an independent third party holds one. No single entity can unilaterally move the Bitcoin. Rehypothecation is mathematically impossible under this arrangement, and collateral is verifiable on-chain at any time. Unchained is SOC 1 and SOC 2 certified and has originated over $500 million in BTC-backed loans since 2016.

How Bitcoin-Collateralized Loans Work

Bitcoin-collateralized loans follow a straightforward lifecycle. The borrower deposits BTC with the lender (CeFi) or into a smart contract (DeFi). The platform issues a loan in fiat or stablecoins based on the LTV ratio: at 50% LTV, $100,000 worth of BTC collateral yields a $50,000 loan.

Most CeFi loans are interest-only with monthly payments and principal due at term end. The borrower's LTV fluctuates as BTC price moves. If Bitcoin drops and LTV rises toward the warning threshold (typically 70%–75%), the platform issues a margin call requesting additional collateral or partial repayment. If LTV reaches the liquidation threshold (80%–90%), the platform sells enough collateral to bring the loan back into compliance.

Upon full repayment, all collateral is returned. The borrower retains any BTC price appreciation that occurred during the loan term. This is the core value proposition: accessing dollar liquidity without selling Bitcoin and without triggering a taxable disposition event.

Liquidation Mechanics Compared

Liquidation is the process by which a platform sells borrower collateral to repay an undercollateralized loan. The mechanics differ substantially between CeFi and DeFi.

DeFi protocols like Aave use on-chain liquidation bots: when a position's health factor drops below 1.0, any third party can call the liquidation function and receive a bonus (typically 5%–8% of the liquidated amount). Aave V4 introduced health-targeted liquidation, which sells only enough collateral to restore the position to health rather than liquidating a fixed percentage. This reduces borrower losses during minor price dips.

CeFi platforms handle liquidation internally. Ledn triggers automatic liquidation at 80% LTV. Nexo uses partial automatic repayment at approximately 83.33% LTV, selling just enough collateral to restore the ratio. Unchained provides margin calls before liquidation, giving borrowers time to add collateral or make a payment.

Cascading liquidations are a systemic risk in DeFi: when a sharp price drop triggers mass liquidations, the resulting sell pressure can push prices lower, triggering more liquidations. This feedback loop contributed to multiple DeFi crises, including the March 2020 "Black Thursday" event on MakerDAO.

Choosing the Right Platform

The best platform depends on your priorities, technical comfort, and loan size.

If you want the lowest variable rates and are comfortable with DeFi wallets: Aave offers the deepest liquidity and broadest collateral support. Compound V3's single-asset model is simpler to reason about. Sky/Spark is the go-to for minting USDS against ETH or BTC collateral.

If you want fixed rates, fiat disbursement, and a regulated experience: Ledn is the strongest option for Bitcoin holders seeking straightforward, transparent terms. Its no-rehypothecation policy and proof-of-reserves reporting address the trust concerns raised by the 2022 CeFi collapses.

If you want flexible repayment with no fixed term: Nexo's credit line model lets you borrow and repay on your own schedule. Rates are competitive at higher loyalty tiers but can be expensive at the base level.

If you want maximum custody control: Unchained's collaborative multisig model means you retain a key to your own collateral. This is the strongest self-custody option in CeFi lending, though the $150,000 minimum and business-only focus limits accessibility.

For users in the Bitcoin ecosystem who want to borrow against BTC without bridging to Ethereum-based DeFi, Spark and USDB provide Bitcoin-native stablecoin infrastructure that can complement borrowing strategies by offering low-cost dollar transfers on Bitcoin.

Regulatory Landscape

The regulatory environment for crypto lending shifted significantly in 2025–2026. The SEC moved away from its prior enforcement-heavy approach, dropping most cases against fintechs based on unregistered activity (without fraud). Yield-bearing crypto accounts offered to retail US customers are still treated as securities, requiring registration.

The GENIUS Act, enacted in 2025, established a federal framework for payment stablecoins. While it does not directly regulate lending, it clarifies the status of the stablecoins used as loan disbursements. The SEC and CFTC issued a joint crypto asset framework in March 2026, though a comprehensive federal lending framework has not yet materialized.

DeFi protocols remain largely outside direct regulatory scope due to their permissionless, non-custodial nature. CeFi platforms face licensing requirements that vary by state and country: Nexo's $500,000 California fine in January 2026 underscores the compliance risks of operating across jurisdictions.

Frequently Asked Questions

What is the cheapest way to borrow against crypto?

DeFi protocols consistently offer the lowest borrow rates. As of mid-2026, Aave's variable stablecoin borrow rates run 3%–4.3% APY, and Compound V3 charges around 2.7%–3.4%. These rates are variable and can spike during high utilization. CeFi fixed rates start higher (9%+ for Ledn, 14%+ for Unchained) but provide rate certainty. Nexo's Platinum tier advertises rates starting at 1.9%, though achieving that tier requires holding 10% of your portfolio in NEXO tokens.

Can I lose my Bitcoin collateral?

Yes. If your loan's LTV ratio exceeds the liquidation threshold, the platform will sell some or all of your collateral to repay the debt. On DeFi platforms, liquidation is automated and irreversible. On CeFi platforms, some lenders issue margin calls before liquidation, giving you time to add collateral. Platform insolvency is another risk: if a CeFi lender fails (as Celsius, BlockFi, and Voyager did in 2022), your collateral may be trapped in bankruptcy proceedings.

What is the difference between a crypto loan and a credit line?

A crypto loan has a fixed term (typically 3–12 months), a set interest rate, and required periodic payments. Ledn and Unchained offer this model. A crypto credit line is open-ended: you can borrow and repay at any time with no minimum installments or fixed due dates. Nexo operates this way. Credit lines offer flexibility but may carry higher rates for users outside top loyalty tiers.

Are crypto loans taxable?

In most jurisdictions, borrowing against crypto is not itself a taxable event because you are not disposing of the asset. However, if your collateral is liquidated, that liquidation is typically treated as a taxable sale. Interest payments may be deductible depending on how the loan proceeds are used. Tax treatment varies by jurisdiction: consult a tax professional for your specific situation.

What happens if a crypto lending platform goes bankrupt?

If a CeFi lender becomes insolvent, your collateral is treated as part of the bankruptcy estate. There is no deposit insurance equivalent for crypto lending. Celsius customers waited over a year for partial recoveries. To mitigate this risk, look for platforms that do not rehypothecate collateral (Ledn), use collaborative custody where you hold a key (Unchained), or use non-custodial DeFi protocols where funds are held by smart contracts rather than a company.

How do DeFi borrow rates change over time?

DeFi rates are determined algorithmically by utilization: the ratio of borrowed assets to supplied assets in a pool. When utilization is low, rates are low to attract borrowers. As utilization rises toward the "kink" point (typically 80%–90%), rates increase sharply to incentivize repayment or new deposits. During periods of high demand (such as airdrop farming or market volatility), stablecoin borrow rates can spike above 10%–20% before reverting.

What collateral can I use for a crypto loan?

DeFi platforms accept the widest range: Aave supports ETH, WBTC, wstETH, USDC, LINK, and over a dozen other tokens across multiple chains. CeFi platforms are more selective: Ledn and Unchained accept Bitcoin only, while Nexo supports 100+ assets including BTC, ETH, and various stablecoins. The LTV ratio you receive depends on the collateral's volatility: BTC and ETH typically get 50%–80% LTV, while more volatile altcoins may be capped at 30%.

This tool is for informational purposes only and does not constitute financial advice. Rates, terms, and platform features change frequently. DeFi rates shown are variable and based on pool utilization at the time of writing. CeFi rates may depend on loyalty tiers, loan size, or promotional periods. Always verify current terms directly with the platform before borrowing. The 2022 CeFi lending collapses demonstrated that no platform is risk-free: evaluate counterparty risk, custody arrangements, and regulatory status before depositing collateral.
