Crypto-Backed Loans Guide: LTV, Rates, Margin Calls and Providers

How does a crypto-backed loan work?

A crypto-backed loan is a secured loan in which your Bitcoin or Ethereum is the collateral. You pledge the coins, the lender advances dollars against a share of their market value, and you keep ownership of the coins for as long as the loan stays within its limits. When you repay, the collateral is released. At origination, the financing can provide liquidity without an immediate sale of the pledged assets. Subsequent liquidation or other disposition may have tax consequences. You never sell, so your position, your cost basis and your holding period stay where they were.

That is the appeal for a long-term holder who needs liquidity: cash without a disposal. The costs are interest, fees and the risk that a fall in the collateral's price forces you to add collateral, repay early or watch the lender sell your coins at a moment you did not choose. This guide covers the mechanics that decide whether that trade works for you: how loan-to-value is set and moves, what the loan actually costs, what triggers a margin call, how centralized and decentralized lenders differ, which providers exist, how the loan is taxed, and how to choose. Abra is one of the providers described, and this guide positions it among the alternatives rather than ahead of them by default.

How does the loan-to-value ratio work on a crypto-backed loan?

Loan-to-value is the loan amount divided by the market value of the collateral. Pledge $100,000 of Bitcoin and borrow $50,000, and your LTV is 50%. The ratio you start at is your choice, up to the lender's maximum. The lower you start, the more the collateral can fall before the lender acts.

LTV is not fixed. It moves every time the Bitcoin price moves. If your $100,000 of collateral falls to $80,000 and the loan is still $50,000, your LTV is now 62.5%. You did nothing; the market did. That is why every crypto-backed loan agreement has two more numbers alongside the maximum LTV: the margin-call level, at which you are asked to add collateral or repay, and the liquidation level, at which the lender sells collateral to protect the loan.

When you compare providers, compare all three numbers, not just the maximum LTV. A lower starting LTV with a wider gap to liquidation generally provides more capacity to absorb a decline in collateral value before reaching the liquidation threshold. A high maximum with a liquidation level close behind it leaves very little room.

What LTV can you borrow against Bitcoin?

It depends on the provider and the asset. Bitcoin and Ethereum are the most widely accepted collateral and generally carry the highest LTV limits, because they are the most liquid. Smaller assets, where accepted, get lower limits. Each provider sets its own ceiling based on volatility, liquidity, and how it handles a stress event.

Loans available through Abra go up to 50% LTV against BTC and ETH, on an open term. The margin-call and liquidation levels are stated in the loan terms, which you receive before signing. Other centralized lenders and DeFi protocols publish their own maximums; the Abra rate-comparison page lists each one with the source and the date it was verified, and says so where a figure could not be verified from the provider's own published terms.

One practical rule: treat the maximum as a ceiling, not a target. Starting below the maximum LTV provides greater capacity for collateral values to decline before reaching a margin-call or liquidation threshold. Borrowers who draw at 25 to 35% LTV against Bitcoin have historically had far more room to ride out drawdowns than those who draw at the limit. The lender's maximum tells you what you can do, not what you should.

What do crypto-backed loans cost?

The advertised rate is only part of the cost. Add the origination or transaction fee, any annual fee on the collateral, any wrapping or network fees, and the cost of the rate being variable and compounding while the loan is outstanding. Two lenders with the same headline rate can differ meaningfully once every disclosed fee is counted.

Rates available through eligible financing opportunities identified by Abra Capital Management “ACM” are variable interest rates and have recently ranged from approximately 4% to 8%. Actual rates and terms are confirmed before a transaction. Abra's borrowing rate is variable, derived from the underlying DeFi lending markets, and typically falls between 4% and 8%. It is confirmed in writing before you sign, together with the fee schedule. Rates verified September 2026. Other providers' current rates are attributed on the Abra rate-comparison page to each lender's published rate on the date checked.

Rates change without notice across the industry, often weekly. Any figure on this page or any other is a snapshot. Before you borrow, pull the current rate from the provider directly and ask for the all-in cost on your loan size, because many lenders tier rates by loan amount and by LTV.

What triggers a margin call, and how does liquidation work?

A margin call is triggered when your LTV crosses the threshold in your loan agreement because the collateral has lost value. Worked example: you pledge $100,000 of Bitcoin and borrow $50,000 at 50% LTV. Bitcoin falls 20%. Your collateral is now worth $80,000 and your LTV is 62.5%. If the margin-call level in your agreement is below 62.5%, you are notified and given a window to cure. The applicable margin-call and liquidation levels are stated in the financing terms provided before the transaction.

You cure a margin call one of two ways. Add collateral: post more Bitcoin so the denominator rises and the LTV falls. Or repay: pay down part of the loan so the numerator falls. If you do neither and the price keeps falling until the LTV hits the liquidation level, the lender sells enough collateral to bring the loan back within limits. In the example, that means selling Bitcoin at $80,000 per $100,000 of your original value, at a moment you did not choose.

Liquidation has two costs beyond the loss of collateral. It is a taxable sale, so a gain on Bitcoin you bought cheaply becomes due. And some lenders charge a liquidation fee. Grace periods differ: some lenders give you a day or more to act, while some DeFi protocols liquidate instantly and automatically. Ask before you borrow.

CeFi vs DeFi lending: who holds the keys?

Centralized finance lenders, including Abra, Figure and Ledn, run the loan as a business. They require identity verification, set terms, and hold or arrange custody of your collateral. Your main risk is the platform: how it holds your collateral, whether it lends it onward, and what happens if it fails. The difference between an omnibus wallet on the lender's balance sheet and a segregated account titled to you is the whole question here, and it is worth reading each lender's custody disclosure.

Decentralized finance protocols, including Aave, Compound and Summer.fi, are smart contracts. No identity check, no operator, and you keep your keys until you deposit collateral into the contract. Terms are set by protocol governance and enforced automatically. Your main risk is the code: a bug or exploit in the contract, an oracle failure, or a liquidation that executes instantly with no one to call.

Repayment terms also differ. Many CeFi lenders offer fixed terms; Abra's loans are open term with no maturity. DeFi loans are open term by design. Neither model is safer in the abstract. CeFi concentrates risk in an institution you can evaluate; DeFi distributes it into code you can read but may not be able to audit yourself.

Which providers offer crypto-backed loans, and when does a competitor fit better?

The main centralized options include Abra, Coinbase, Figure, Ledn and Nexo; the main DeFi options include Aave, Compound and Summer.fi. Each provider's maximum LTV, rate, term and custody model is attributed to its published terms, with the verification date, on the Abra rate-comparison page. That page, not this one, is where the figures live, so they can be re-verified without rewriting the guide.

Abra fits a borrower who wants collateral held in a separately managed account titled to them under an SEC-registered investment adviser, an open-term loan with no prepayment fee, up to 50% LTV, and a variable interest rate, typically 4% to 8%, that tracks DeFi lending markets. It fits less well if you need a higher LTV, a fixed-rate term loan, or collateral in an asset other than BTC or ETH.

A competitor may fit better in specific cases. If you want a fixed rate for a fixed period, a lender that offers term loans is the right tool. If you want to borrow against a smaller asset, look for a lender that lists it. If you want no identity verification and are comfortable managing your own keys and liquidation risk, a DeFi protocol is the only route. If you want an established lender with a long track record of Bitcoin-only loans, Ledn and Figure are worth reading directly. Read the custody and rehypothecation disclosure of every provider before deciding.

Is a crypto-backed loan taxable?

Generally, no. Under current IRS guidance, borrowing against an asset is not a sale, exchange or other disposition of it. You keep ownership of the Bitcoin, your cost basis and holding period are unchanged, and the loan proceeds are not income. This is why crypto-backed loans are often described alongside the 'buy, borrow, die' approach used with other appreciated assets: you access the value without realizing the gain.

Two exceptions matter. If your collateral is liquidated, that is a sale, and any gain is taxable in that year, possibly on top of losing the collateral. And whether the interest is deductible depends on what you use the proceeds for; interest on a loan used for personal spending is generally not deductible, while interest on a loan used for investment or business may be, subject to limits. Abra does not provide tax advice. Confirm your position with a qualified adviser.

How do you choose a crypto loan provider?

Run this checklist against every provider, including Abra. If a provider cannot answer any of these in writing, that is your answer. The full mechanics are covered on the Abra loans product page, and the tax questions in the guide linked above.

• Where is the collateral held, and is the account titled to you or is it an omnibus wallet?
• Is the collateral rehypothecated?
• Who regulates the lender, and can you verify it?
• What are the maximum LTV, the margin-call level and the liquidation level, and are all three in the agreement?
• What is the grace period to cure a margin call?
• What is the current rate, is it fixed or variable, and how is it set?
• What are the origination, annual, network and liquidation fees?
• Is there a prepayment penalty?
• What is the all-in cost on your loan size for twelve months?
• How do you repay, how quickly is collateral released, and what happens if the lender fails?
