A guide to Bitcoin collateralised lending, on-chain, off-chain and everything between
The problem every Bitcoin holder eventually faces
Whether you are a digital asset treasury, a miner sitting on reserves, a fund managing LP capital, or an individual with a meaningful position, the same problem arrives – you need liquidity, but selling defeats the purpose of holding.
Selling triggers tax liabilities (capital gains) in most jurisdictions, sometimes north of 30%. You lose the position and its future upside on an asset that has appreciated in 78 of the last 100 months.
Bitcoin collateralised lending is one alternative holders consider. The concept mirrors traditional secured lending. If you borrow against your house, the bank lends you 70-80% of its value, not 100%. The loan is overcollateralised i.e the lender has the safety and sufficient protections of knowing the collateral is worth more than the loan issued. Bitcoin backed lending follows the same logic. Pledge BTC worth more than the loan, borrow dollars or stablecoins, keep the asset. No sale, no tax event, no lost upside in jurisdictions where borrowing is not treated as a disposal.
Crypto collateralised lending hit $73.6 billion in outstanding loans in Q3 2025, surpassing the previous cycle peak. On-chain lending alone reached $26.5 billion, up 42% in a single quarter. DeFi protocols now hold two thirds of the total market, up from under half four years ago. The majority of that lending is collateralised against Bitcoin. This is not accidental. Lenders gravitate toward the asset they can price, verify, and liquidate most efficiently and no other crypto asset matches Bitcoin on all three. The market that emerged from the 2022 collapses is structurally different, more collateralised, more transparent, increasingly integrated with traditional capital markets.
This is not a niche. It is an emerging, fast growing credit market built mainly on pristine collateral.
Why Bitcoin is pristine collateral
Property requires months of conveyancing; foreclosure takes years. Business assets need independent valuation with no liquid secondary market. Gold requires physical custody, assay verification, storage and insurance. Even US Treasuries have settlement cycles, market hours and require a custodian to enforce a claim.
Bitcoin has none of those constraints. Priced 24/7 on a global market with billions in daily volume. Transferable instantly. Verifiable on-chain. Callable the moment a threshold is breached. No courts, no legal process, no 18 month enforcement timeline.
A lender who can liquidate within minutes, at any hour, anywhere in the world, carries fundamentally less risk than one waiting on a court order. That reduced risk translates directly into better terms for borrowers. This is why JPMorgan, Citi, Wells Fargo and BNY Mellon now lend against it.
Pristine collateral is an asset that can be priced, verified, transferred and enforced without friction, at any hour, anywhere in the world. Besides Bitcoin, no other widely traded asset currently meets all four criteria simultaneously.
How it works
Deposit Bitcoin as collateral. The lender advances dollars or stablecoins. Use the capital. Repay the loan plus interest, get your Bitcoin back.
There are two metrics that govern every Bitcoin-backed loan. The first is your borrow LTV (Loan-to-Value): the ratio of your loan to your collateral at origination. Borrow $50,000 against $100,000 in BTC and your borrow LTV is 50%. Most CeFi platforms cap this at 50-70% and on-chain can go higher. The second is your liquidation threshold: the LTV level set by the platform or protocol at which your collateral is sold (liquidated) to repay the loan. This typically sits at 80-85%. These are separate numbers and confusing them is one of the most common mistakes new borrowers make. Your borrow LTV determines how much you take out. Your liquidation threshold determines when you lose your Bitcoin. The gap between them is your margin of safety.
Liquidation formula: Liquidation Price = Entry Price × (Borrow LTV / Liquidation Threshold). At $100,000 BTC with a 50% borrow LTV and an 80% liquidation threshold, liquidation hits at $62,500, a 37.5% drop. At 60% borrow LTV: $75,000, a 25% drop. At 70%: $87,500, just 12.5%. The wider the gap, the safer the position.
One detail that catches borrowers. Some platforms capitalise interest into the loan balance. Your LTV creeps upward even if BTC price holds flat. A loan opened at 50% can drift to 55%+ within months from accrued interest alone. Check whether your platform capitalises interest and factor it into your buffer.
Off-chain, origination takes hours. On-chain, it is instant. Both are faster than traditional secured lending because overcollateralisation removes the need for credit assessment.
On custody: off-chain, BTC transfers to third party custody. You retain beneficial ownership but the asset is pledged for the loan’s duration. On-chain, wrapped BTC is locked in a smart contract. In both cases you retain economic exposure to BTC price movements, but the asset is not freely available until repayment.
At maturity, most CeFi platforms allow loan rollovers at prevailing rates, and some offer top up facilities where appreciated collateral supports additional borrowing. On-chain, positions remain open indefinitely as long as LTV stays below the liquidation threshold.
The benefits
- Potential tax efficiency, depending on jurisdiction
In most jurisdictions, borrowing against an asset is not a taxable event. Selling is. Selling to raise $200,000 could generate $60,000+ in tax. Borrowing the same amount generates zero. You keep the Bitcoin, the cash and the $60,000.
BTC on-chain. The UK has ruled that wrapping BTC does not constitute a disposal for capital gains purposes, provided beneficial ownership is unchanged. The US and EU remain less clear, which is one reason larger institutional allocators remain cautious about on-chain lending in those jurisdictions.
Tax note: This article does not constitute tax advice. Tax treatment varies by jurisdiction. Confirm your local treatment before structuring a position.
- Maintained upside exposure
In most structures, borrowers retain beneficial ownership and full economic exposure. If Bitcoin doubles while your loan is open, you capture that appreciation.
Miners are the most natural users. They hold BTC reserves but face USD denominated costs. Borrow against reserves, fund operations, repay from future mined Bitcoin. No dilution and no asset sales at cyclical lows. Digital asset treasuries face the same dynamic.
- Portfolio management without rebalancing
Traditional wealth management tells a concentrated holder to diversify. That advice costs you the position. Collateralised borrowing lets you extract capital from a concentrated BTC holding without rebalancing. Deploy borrowed capital elsewhere while keeping exposure intact. For holders whose thesis is long term appreciation, this is one of the few ways to access utility without undermining the thesis.
- The carry trade
Borrow stablecoins against BTC and deploy into a higher yielding strategy. On-chain borrow rates currently sit at 4.25%, so deployment targets need to clear that meaningfully. Some borrowers target tokenised yield, private credit strategies, or structured DeFi vaults, though any deployment strategy carries its own risk profile and requires independent assessment. Deploying below your borrow cost is negative carry, amplified sharply if your rate is variable. On-chain rates are predominantly variable, adjusting algorithmically with pool utilisation. Off-chain rates are predominantly fixed. A variable rate can spike precisely when conditions deteriorate, inverting your spread and costing you additional money to hold the position at the worst moment. Fixed rate on-chain options are emerging rapidly (Morpho Midnight and others) to address institutional demand for rate certainty.
Five carry trades risks to understand and price.
- liquidation (BTC drops, collateral sold),
- Counterparty (platform or contract failure),
- Negative carry (yield falls below borrow cost), and
- FX (currency or peg mismatch).
- Liquidity (depth and speed of exiting)
Overcollateralised means no credit checks. Your Bitcoin is your credit. Off-chain funds in hours, on-chain is instant. For companies with Bitcoin treasuries, this provides working capital without equity dilution or asset sales.
On-chain vs. Off-chain
Off-chain (CeFi)
Deposit BTC with a centralised platform or prime broker. Used by Ledn, Unchained, Nexo, and institutional bank desks.
| Feature | Off-chain (CeFi) |
| Custody | Platform or qualified third party custodian |
| LTV range | ~50% conservative; up to 70% |
| Borrow rates | 8-12% APR retail; ~6-7% commercial scale, typically fixed |
| Liquidation | Margin call first, human in the loop |
| Speed | Hours to days |
The advantages: margin calls, fixed rates, bespoke structuring. If BTC drops, you get a call before liquidation with a window to respond. Rates are fixed at origination, giving predictable cost for the loan’s life. Terms (size, duration, LTV, collateral management) can be tailored. For treasuries modelling cash flows, rate certainty and flexibility is a requirement, not a convenience.
When a margin call arrives, you typically have three options: post additional BTC to reduce LTV, make a partial USD/stablecoin repayment, or accept partial liquidation. Response windows range from 24-72 hours in orderly markets to as little as a few hours during sharp sell-offs. Know the process before you need it.
The risk is counterparty exposure. If the platform fails, your claim depends on legal structure, custody arrangement and whether your assets were rehypothecated.
Ledn: the post 2022 benchmark
Ledn has originated over $10.2 billion in loans since 2018 with a perfect track record through the 2022 crisis. In February 2026, Ledn closed a $188 million asset backed securities (ABS) issuance backed by Bitcoin collateralised loans. S&P Global assigned BBB- investment grade status, the first for a digital asset lending portfolio. The deal was over two times oversubscribed. Collateral is ring-fenced, rehypothecation is prohibited and the platform publishes regular Proof of Reserves attestations.
This ABS connects Bitcoin backed lending directly to traditional fixed income markets. Pension funds and insurance companies can now access Bitcoin backed cash flows through a rated structure they already understand.
Ledn’s BBB- rating is five intermediate grades higher than DeFi lender Sky and Strategy, both rated B-. Bitcoin-backed credit, properly structured, is now rated on par with sovereign debt from Hungary and Morocco.
On-chain (DeFi)
Wrapped Bitcoin deposited into a smart contract. No human in the loop. Cross the liquidation threshold and collateral is sold automatically.
| Feature | On-chain (DeFi) |
| Custody | Smart contract holds wrapped BTC (WBTC, cbBTC, rBTC) |
| LTV range | 60-90% |
| Borrow rates | 3-6% APY variable; fixed rates emerging |
| Liquidation | Automated, no human discretion |
| Speed | Instant |
Rates of 3-6% (currently 4.245%) are materially cheaper than CeFi because protocols eliminate operational overhead. Rules are encoded on-chain, verifiable before you deposit and immutable mid loan. However, rates are variable and can spike sharply during high utilisation periods.
The major protocols: Aave ($19.4B TVL), Morpho ($7.2B TVL, with Coinbase and Apollo Global integrations), Spark ($6.8B), Compound ($2.7B). Coinbase routes Bitcoin-backed loans through Morpho on Base, with over $2.17 billion in USDC originations.
Wrapping: risk in context
On-chain borrowing requires native BTC to be wrapped. WBTC relies on BitGo as custodian. cbBTC is Coinbase wrapped. Both are backed by large, regulated institutions. rBTC is different in kind: it is the native Bitcoin representation on the Rootstock network, secured by over 80% of Bitcoin’s hashrate via merge-mining rather than a custodial arrangement. The risk profile across all three is materially different from smaller, less battle tested bridges, but any wrapping layer carries a dependency that native BTC does not.
CeFi vs. DeFi: side-by-side
| Dimension | CeFi (off-chain) | DeFi (on-chain) |
| Rates | 8-12% APR retail, ~6-7% commercial; fixed | 3-6% APY; variable. 4,25% currently (fixed emerging) |
| LTV | 20-50% | 60-90% |
| Liquidation | Margin call + human discretion | Automated |
| Custody | Platform or qualified custodian | Smart contract |
| Counterparty risk | Platform solvency + rehypothecation | Smart contract + bridge risk |
| Tax clarity | Clearer (no wrapping required) | Wrapping may trigger disposal |
| Speed | Hours to days | Instant |
| Best for | Treasuries, large positions, institutional | DeFi-native, rate-sensitive borrowers |
On-chain gives you lower rates, instant execution, full transparency and capabilities that do not exist off-chain: flash loans (borrow and repay in a single transaction for arbitrage, collateral swaps, or self-liquidation), composability (automated risk management across protocols), no KYC, no minimum loan size, no banking relationship required. The trade-offs: automated and final liquidations, variable rates, smart contract and bridge risk with no human recourse.
Off-chain costs more but delivers fixed rate certainty, personal margin calls, bespoke structuring and relationship managed service. For treasuries and larger allocators, a fixed rate and a human on the other end of a margin call is often worth the premium.
The constraints
- Liquidation risk
The number one risk to really understand. If BTC drops and your LTV crosses the threshold, collateral gets sold. CeFi gives a margin call first. On-chain, liquidation is automated. In sharp drawdowns, liquidations cascade: price drops trigger sales, which trigger more liquidations.
Probability of liquidation?
Bitcoin has spent over 80% of its history in a 20%+ drawdown from its all time high. Corrections of 30-40% occur multiple times per bull cycle. Since 2014, four drawdowns have exceeded 50%. A drawdown large enough to liquidate a poorly buffered position is inside the normal probability distribution of a bell curve.
When you enter matters as much as what LTV you choose. A loan opened near a cycle high carries a fundamentally different risk profile to one opened after a significant correction. A 50% LTV loan taken out at $126,000 in October 2025 would have faced liquidation pressure within months as BTC fell over 46%. The same 50% LTV loan opened today, after a 40%+ correction, has materially more room beneath it because the entry price already reflects the drawdown. This does not mean the risk is gone, BTC can always fall further, but the probability of a liquidation triggering move from a post correction entry is structurally lower than from a cycle peak. Entry point relative to the market cycle is one of the factors that has historically affected liquidation probability.
| Starting LTV | Liquidation Threshold LTV | BTC drop to liquidation | Price ($100K entry) | Historical frequency |
| 50% | 80% | 37.5% | $62,500 | Occurs in most bear markets |
| 50% | 85% | 41.2% | $58,824 | Occurs in major corrections |
| 60% | 80% | 25.0% | $75,000 | Multiple times per cycle |
| 60% | 85% | 29.4% | $70,588 | Multiple times per cycle |
| 70% | 80% | 12.5% | $87,500 | Several times per year |
| 70% | 85% | 17.6% | $82,353 | Several times per year |
Historically, operators who have avoided liquidation tend to keep LTV well below 50% and buffer actively.
- Negative carry and rate risk
If you borrow to deploy into yield, the spread can go negative. Variable on-chain rates spike when utilisation increases. If your yield compresses simultaneously, the carry inverts and you need to fund the additional costs.
- Counterparty risk (CeFi)
Rehypothecation was the structural cause of the 2022 collapses. Before depositing: verify Proof of Reserves, confirm regulated custodian, confirm rehypothecation is prohibited, understand your claim in bankruptcy.
- Smart contract and bridge risk (DeFi)
Code risk replaces counterparty risk. The dominant protocols (Aave, Morpho, Compound) are battle-tested and hardened. When Aave faced ~$230 million in bad debt from the April 2026 KelpDAO exploit, a coalition raised over $300 million to cover the shortfall. That response was possible because of Aave’s scale and ecosystem relationships. Smaller protocols would not have that backstop.
This is not a passive strategy
Know your liquidation price before you open. Set alerts at LTV thresholds. Pre-plan your response – at what LTV do you add collateral, partially repay, or close?
Carry Trade. Know your borrow rate and break even in real time. If the spread compresses, how quickly can you unwind? Liquidity and redemption times are the silent killer. In market stress, on-chain liquidity thins and off-chain redemptions can take days.
Know where your collateral sits. In CeFi: the custodian, legal structure, rehypothecation policy. In DeFi: the contract, oracle, liquidation engine, governance risk.
What comes next: Bitcoin credit markets
Most Bitcoin backed lending stops at origination. You post collateral, get a loan, and it sits on the lender’s book until repaid. In mature financial systems, origination is just the beginning. The mortgage market is the analogy. A bank originates a loan, packages it into a mortgage backed security (MBS), sells it to investors and frees capital to lend again. The MBS market exceeds $12 trillion. Bitcoin backed lending is at the very beginning of the same financializaition evolution.
Ledn’s ABS issuance is the first bridge. Galaxy, Coinbase Prime and others are building institutional desks routing traditional fixed income capital into Bitcoin backed products. On-chain, Morpho Midnight (launched April 2026) offers fixed rate, fixed term products for institutional borrowers. The direction is clear, bilateral origination is evolving into a full credit market with securitisation and institutional distribution.
The Lending market is maturing
MiCA is live in Europe. SAB 121 has been repealed, allowing US banks to custody crypto on balance sheet. The GENIUS Act is progressing through Congress. Proof of Reserves and third party attestations are now industry standard transparency requirements. The capital stack has shifted from retail deposits funding retail loans to rated securities attracting institutional capital. What is being built now is overcollateralised, transparent and integrated with the same regulatory and ratings infrastructure that governs traditional credit. The tailwinds are aligned; regulatory clarity, institutional acceptance and maturing infrastructure are converging to accelerate the financialisation of Bitcoin through products like collateralised lending over the next five to ten years.
Your Bitcoin. Your liquidity. Your terms.
Bitcoin collateralised borrowing solves a genuine demand problem, accessing liquidity without sacrificing the best performing asset of the last decade. Tax efficiency potential, maintained upside exposure, carry trade optionality, speed and accessibility – these are the benefits holders cite. None come without trade-offs.
None of this is passive though and risks exist. The difference between a well managed position and a loss is preparation. Know your LTV, liquidation price, where your collateral sits, your borrow rate and your exit plan before you open.
Bitcoin collateralised lending has grown up. Regulated institutions are lending against it. Rated securities are being issued against it. On-chain infrastructure is maturing to institutional grade. The demand for liquidity without disposal is structural, growing fast, and the market is building to meet it. For holders who understand the mechanics and risks, Bitcoin collateralised lending is among the more significant financial tools to emerge from this asset class.
