Bitcoin-Collateralized Loans: Rates, LTV, and Liquidation Compared
Compare platforms offering loans backed by Bitcoin collateral on interest rates, LTV ratios, liquidation policies, and custody.
Bitcoin-Collateralized Loan Platforms Compared
Bitcoin-collateralized loans let holders borrow dollars (or stablecoins) against their BTC without selling it, preserving upside exposure while accessing liquidity. After the collapse of Celsius, BlockFi, and Voyager in 2022, the market restructured around stricter collateral segregation, conservative LTV ratios, and proof-of-reserves audits. Total crypto lending volume reached $67 billion in Q1 2026, with BTC-backed loans representing a growing share as institutional infrastructure matures.
The table below compares the major platforms offering crypto lending against Bitcoin collateral, spanning both CeFi custodial services and DeFi protocols.
| Platform | Type | Interest Rate (APR) | Max LTV | Min Loan | Loan Term | Custody Model |
|---|---|---|---|---|---|---|
| Unchained | CeFi | ~14.18% effective (12% + 2% origination) | 50% | $150,000 | 360 days | 2-of-3 multisig |
| Ledn | CeFi | 9.25% to 11.49% | 50% | $1,000 | 12 months | Custodial (segregated) |
| SALT Lending | CeFi | 7.49% to 10.50% | 70% | $5,000 | 1, 3, or 5 years | Custodial |
| Nexo | CeFi | 1.9% to 18.9% (tier-based) | 50% | $50 | Revolving (no fixed term) | Custodial |
| Strike | CeFi | 9.5% to 14.2% | 50% | $10,000 | 6 or 12 months | Custodial (Coinbase/BitGo) |
| Aave (wBTC) | DeFi | ~3% to 8% variable | 73% | None (gas-limited) | Open-ended | Smart contract |
| Sovryn Zero | DeFi | 0% (+ 0.5% to 3% origination) | ~91% | None | Open-ended | Smart contract (RSK) |

CeFi Platforms: Custodial Bitcoin Lending
CeFi (centralized finance) platforms handle custody, margin monitoring, and loan servicing on behalf of the borrower. The tradeoff is convenience and fiat disbursement at the cost of counterparty risk. Post-2022, the surviving CeFi lenders have adopted stricter practices: collateral segregation, proof-of-reserves audits, and conservative LTV caps.
Unchained
Unchained stands apart by using a 2-of-3 multisig vault where the borrower holds one key, Unchained holds one, and a third-party key agent holds the last. This means no single party can move the collateral unilaterally, and Unchained cannot rehypothecate it. However, since January 2024, Unchained restricts lending to business entities (LLCs and corporations) with a $150,000 minimum. Consumer loans are no longer available. The effective APR of roughly 14.18% (12% annual rate plus a 2% origination fee) is higher than most competitors, but the multisig custody model offers meaningful protection against platform insolvency.
Ledn
Ledn has emerged as one of the leading BTC-backed lenders following the 2022 shakeout. Rates range from 9.25% for loans above $1 million to 11.49% for loans under $250,000. Collateral is held in segregated cold storage with no rehypothecation, and the platform has completed over ten consecutive proof-of-reserves audits. In February 2026, Ledn completed a $188 million Bitcoin-backed asset-backed security that earned an investment-grade rating from an NRSRO: a first for the Bitcoin lending industry. Loans are fixed 12-month terms with monthly interest-only payments, no prepayment penalties, and no credit checks.
SALT Lending
SALT offers the longest loan terms in the CeFi space: up to five years at rates between 7.49% and 10.50% depending on LTV and duration. A 30% LTV one-year loan starts at 7.49% APR, while maximum LTV (70%) is only available on one-year terms at 10.50%. SALT charges zero origination, prepayment, or custody fees, making its headline rate closer to the true cost. The platform also offers a "SALT Shield" product for additional volatility protection. The main downside is fully custodial collateral management without the multisig protections that Unchained or Debifi provide.
Nexo
Nexo returned to the US market in February 2026 through a partnership with Bakkt, following a $45 million SEC settlement and a multi-year exit. Its lending product operates as a revolving credit line with no fixed term: borrowers draw against their crypto portfolio and repay on their own schedule. Advertised rates range from 1.9% to 18.9% APR, but the lowest tiers require holding 10% or more of your portfolio in NEXO tokens (Platinum tier). Most borrowers without significant NEXO token holdings will pay toward the higher end of that range. The $50 minimum loan makes it accessible for small borrowers, but the tiered structure benefits the platform's token ecosystem as much as the user.
Strike
Strike launched BTC-backed lending in May 2025, backed by a $2.1 billion credit facility from Tether. Standard loans start at 9.5% APR (7.5% for loans over $5 million) with a 50% LTV and 12-month term. In July 2026, Strike introduced "volatility-protected" loans at up to 14.2% APR that eliminate price-based margin calls entirely: the only liquidation trigger is a missed payment (with a 10-day grace period). This is a unique feature in the market. However, an important detail often overlooked: Strike's terms permit single rehypothecation of collateral to third-party capital providers. Collateral is held with Coinbase and BitGo. Despite Strike being a Lightning Network-native payments company, the lending product does not use Lightning mechanics for collateral management.
DeFi Protocols: Permissionless Bitcoin Lending
DeFi lending protocols replace custodians with smart contracts. There is no KYC, no credit check, and no human intermediary. The tradeoffs are smart contract risk, the need to wrap BTC for Ethereum-based protocols, and the complexity of self-managing collateral ratios.
Aave (wBTC Collateral)
Aave is the largest DeFi lending protocol with over $14.6 billion in TVL. Borrowers deposit wBTC as collateral and borrow stablecoins (USDC, USDT, DAI) at variable rates typically between 3% and 8% APY. The maximum LTV for wBTC is 73%, with liquidation triggered at 78%. Loans are open-ended with no maturity date. There is no minimum and no KYC. The core risk is twofold: smart contract vulnerabilities in Aave itself, and the custodial risk of wBTC (BitGo holds the underlying BTC). Aave announced a partnership with Babylon in December 2025 to enable native Bitcoin lending without wrapped tokens, but this integration is still in development.
Sovryn Zero
Sovryn operates on Rootstock (RSK), a Bitcoin sidechain, offering 0% ongoing interest on loans. Borrowers pay only a one-time origination fee of 0.5% to 3% and can maintain their position indefinitely as long as the collateral ratio stays above 110% (equivalent to roughly 91% LTV). Loans are denominated in ZUSD or DLLR (Sovryn's native stablecoins). The protocol is fully non-custodial and permissionless. The downsides: RSK has significantly lower liquidity than Ethereum, ZUSD/DLLR have limited off-ramp options, and bridging BTC to RBTC introduces additional trust assumptions.
Peer-to-Peer Alternatives
A third category sits between CeFi and DeFi: peer-to-peer marketplaces where individual lenders and borrowers set terms directly.
Debifi, a sister project of Hodl Hodl based in Lugano, uses a non-custodial 3-of-4 multisig model with keys distributed among trusted parties. There is no rehypothecation and each loan has a unique multisig address on Bitcoin's base layer. Debifi exited beta in June 2025 and subsequently partnered with Swiss digital asset bank Sygnum to offer institutional-grade BTC-backed loans. Minimums start at $20,000 with terms up to five years.
Hodl Hodl Lend operates a similar marketplace using 2-of-3 multisig escrow. Rates and terms are set by individual participants. Both platforms require no KYC, but liquidity is thinner than centralized alternatives.
Liquidation Mechanics Compared
Understanding how each platform handles liquidation is critical during periods of Bitcoin volatility. A 30% BTC price drop can push a 50% LTV loan into margin call territory within hours. The table below shows how each platform manages this risk.
| Platform | Margin Call Trigger | Cure Window | Liquidation Trigger | Liquidation Penalty |
|---|---|---|---|---|
| Unchained | Undisclosed (200% collateral buffer) | Not publicly stated | Undisclosed | Not publicly stated |
| Ledn | 70% LTV, then 75% LTV | Alerts at each threshold | 80% LTV (auto partial liquidation) | Partial sell to restore ratio |
| SALT | Varies by LTV tier | Stabilization process | Below collateral threshold | 3% stabilization + 5% liquidation fee |
| Nexo | ~65% to 70% LTV | Alert-based | ~70% to 83% LTV | Partial auto-liquidation |
| Strike (standard) | 70% LTV | 72 hours | 85% LTV | Forced full liquidation |
| Strike (volatility-protected) | None | N/A | Payment default only (10-day grace) | Post-default sale |
| Aave (wBTC) | N/A (no alerts) | None (instant) | 78% LTV | ~5% to 6.25% liquidation bonus |
| Sovryn Zero | N/A | None (instant) | Below 110% collateral ratio | ~10% penalty |
DeFi liquidations are instant and automated: there is no phone call, no grace period, and no negotiation. CeFi platforms typically offer margin call alerts and time windows to add collateral or make partial repayments. Strike's volatility-protected loans are the only product in the market that eliminates price-based liquidation entirely, trading that protection for a higher interest rate.
Managing LTV During Bitcoin Volatility
Bitcoin's historical volatility makes LTV management the single most important skill for BTC-backed borrowers. Several strategies can reduce the risk of forced liquidation:
- Borrow at a lower LTV than the maximum. A 30% to 40% LTV provides a substantial buffer before margin call thresholds. At 30% LTV, Bitcoin would need to drop roughly 60% before a typical 75% liquidation trigger is reached.
- Use platforms with auto top-up features. Ledn, for example, can automatically add collateral from a linked wallet when LTV rises.
- Keep reserve BTC available to post as additional collateral on short notice. Some borrowers maintain a separate cold storage reserve specifically for this purpose.
- Consider volatility-protected products. Strike's no-margin-call loans eliminate price-based liquidation risk entirely, at the cost of a higher APR and shorter term.
- Monitor LTV actively during drawdowns. Bitcoin has experienced drawdowns of 50% or more multiple times in its history. A 50% LTV loan originated at $100,000 BTC would face margin calls if BTC falls to roughly $65,000 to $70,000 on most platforms.

Custody and Counterparty Risk
The 2022 lender collapses demonstrated that custody model selection is not theoretical: borrowers on platforms that commingled or rehypothecated collateral lost access to their BTC in bankruptcy proceedings. Today, the spectrum of custody approaches ranges from fully custodial to fully non-custodial:
- Multisig (Unchained, Debifi, Hodl Hodl): borrower retains a key and no single party can move funds unilaterally. Strongest protection against platform insolvency.
- Segregated custodial (Ledn): platform holds collateral but in bankruptcy-remote, segregated cold storage with third-party verification. No rehypothecation.
- Custodial with rehypothecation (Strike): collateral can be pledged to third-party capital providers per the platform's terms. Borrowers bear additional counterparty risk from the rehypothecation chain.
- Smart contract (Aave, Sovryn): collateral is locked in audited code. No human custodian. Risk shifts to smart contract bugs and oracle failures.
Borrowers who prioritize self-custody principles should favor multisig or smart contract models. Those who value convenience and fiat disbursement may accept custodial tradeoffs, but should verify whether the platform rehypothecates collateral and what protections exist in insolvency.
US Availability
Regulatory availability is a practical constraint for US-based borrowers. Most CeFi platforms exclude certain states due to licensing requirements:
- Unchained: available in most states but excludes New York, Vermont, Nevada, and several others. Business entities only.
- Ledn: excludes California, Connecticut, Hawaii, Nevada, and approximately six other states.
- SALT: excludes New York, Hawaii, and a few additional states.
- Nexo: available in 49 states (all except New York) following its February 2026 US relaunch.
- Strike: available in most states with specific exclusions.
- Aave and Sovryn: permissionless protocols accessible from anywhere, though some frontend interfaces may implement geo-restrictions.
New York is the most commonly excluded state across CeFi lenders due to the BitLicense requirement and the state's strict lending regulations.
Bitcoin-Native Lending and Lightning
A common question is whether Lightning Network-native lending exists. As of mid-2026, no lending protocol operates directly on Lightning. Strike, despite being a Lightning-native payments company, uses traditional custodial collateral mechanics for its lending product.
The broader trend is toward native Bitcoin collateral that avoids wrapped tokens like wBTC. Aave's partnership with Babylon aims to enable trustless Bitcoin vaults for DeFi lending without wrapping. Discreet log contracts (DLCs) offer another path to non-custodial BTC-backed lending directly on Bitcoin's base layer. Platforms like Spark are expanding what is possible on Bitcoin's second layer, and as the protocol ecosystem matures, native Bitcoin lending without wrapping or bridging may become practical.
Frequently Asked Questions
What is a Bitcoin-collateralized loan?
A Bitcoin-collateralized loan lets you deposit BTC as collateral and borrow dollars or stablecoins against it. You retain ownership of the Bitcoin (subject to the platform's custody model) and receive it back when the loan is repaid. If the value of your BTC collateral drops below the platform's required ratio, you may face a margin call or automatic liquidation. The key benefit is accessing liquidity without triggering a taxable sale of your Bitcoin.
What LTV ratio is safest for a Bitcoin-backed loan?
Most platforms offer maximum LTV ratios between 50% and 73%, but borrowing at the maximum is risky given Bitcoin's volatility. A 30% to 40% LTV is generally considered conservative: at 30% LTV, Bitcoin would need to fall roughly 60% before triggering liquidation on a platform with a 75% liquidation threshold. Historical drawdowns of 50% or more have occurred multiple times, so borrowing near the maximum LTV leaves very little margin for error.
Can I get a Bitcoin-backed loan without KYC?
Yes. DeFi protocols like Aave and Sovryn require no identity verification: you connect a wallet, deposit collateral, and borrow permissionlessly. Peer-to-peer platforms like Hodl Hodl and Debifi also operate without KYC. All CeFi platforms (Unchained, Ledn, SALT, Nexo, Strike) require full KYC/AML verification. The tradeoff for no-KYC platforms is typically higher technical complexity, the need to manage your own self-custody, and less recourse if something goes wrong.
What happens if Bitcoin crashes while I have a loan?
If Bitcoin's price drops significantly, your loan's LTV ratio rises. Most CeFi platforms issue margin call alerts when LTV reaches 65% to 75% and give you a window (typically 24 to 72 hours) to add collateral or make a partial repayment. If you fail to respond, the platform will liquidate some or all of your BTC to cover the loan. DeFi protocols like Aave liquidate instantly and automatically with no grace period. Strike's volatility-protected loans are the only product that eliminates price-based liquidation, but they charge a higher APR for that protection.
Which Bitcoin lending platform has the lowest interest rate?
Sovryn Zero charges 0% ongoing interest with only a one-time origination fee (0.5% to 3%), making it the cheapest option for long-term borrowing. Among CeFi platforms, SALT offers rates starting at 7.49% APR for conservative (30% LTV) one-year loans. Nexo advertises rates as low as 1.9%, but that requires Platinum tier loyalty status and significant NEXO token holdings. Aave's variable rates for borrowing stablecoins against wBTC typically range from 3% to 8% APY. Compare the true cost by accounting for origination fees, loyalty requirements, and compounding method.
Is it safe to use Bitcoin as loan collateral after the Celsius collapse?
The industry has changed significantly since 2022. Surviving platforms adopted stricter practices: collateral segregation, proof-of-reserves audits, no (or disclosed) rehypothecation, and conservative LTV caps. Ledn has completed over ten consecutive proof-of-reserves audits and issued the first investment-grade rated Bitcoin-backed security. Unchained's multisig model prevents the platform from unilaterally accessing collateral. However, no CeFi platform is risk-free. Borrowers who want to eliminate custodial risk entirely should consider DeFi protocols or multisig-based P2P platforms, accepting the tradeoff of higher technical complexity.
What is the difference between CeFi and DeFi Bitcoin lending?
CeFi platforms (Unchained, Ledn, SALT, Nexo, Strike) are companies that custody your collateral, handle margin calls, and disburse loans in fiat or stablecoins. They require KYC and operate under specific jurisdictional regulations. DeFi protocols (Aave, Sovryn) use smart contracts to automate the entire process: no KYC, no human intermediary, and no custodian. CeFi offers convenience, fiat disbursement, and customer support. DeFi offers permissionless access, on-chain transparency, and no counterparty risk from a company going bankrupt, but introduces smart contract risk and requires technical competence.
