Unchained Capital vs CoinRabbit review: Two approaches to crypto-backed loans

Unchained Capital and CoinRabbit both offer crypto-backed loans, but their business models differ significantly. This comparison examines the two platforms side by side, covering borrower eligibility, loan terms, custody, fees, and the services each provides to institutional and high-net-worth clients.

Platform overviews

Unchained has originated more than $1 billion across over 1,000 Bitcoin-backed loans and reports that no client Bitcoin has been lost along the way. The lending product is documented throughout as a business facility, in the sense that the borrower is a company, the paperwork is a commercial loan application, and the marketing addresses corporate treasuries. Individuals arriving at the site are routed toward custody, retirement and trading products instead, so the first question the comparison settles is not the rate but who is eligible to borrow at all.

CoinRabbit launched in 2020 as a crypto asset management platform and has issued more than $1.45 billion in crypto loans against 100% reserves. Lending sits inside a wider account that also holds a wallet, swaps and yield products. The operating principle is that the collateral does the qualifying, so a crypto loan opens without an approval stage and without a credit check. Funding is measured in minutes rather than days. Clients with portfolios of $500,000 or more can access the Private Program, which includes a dedicated account manager, customized loan terms, crypto loan restoration, cross-collateralization, and other tailored services.

Unchained Capital vs CoinRabbit: Crypto loan products and terms

Unchained accepts Bitcoin and nothing else. Loans run twelve payments of 30 days, interest only, with the principal falling due alongside the final payment, and pricing is published rather than negotiated: 12% interest and a 14.18% APR, with the gap between them accounted for by a 2% origination fee that Unchained adds to the amount borrowed rather than deducting from the amount disbursed. Leverage is quoted as a collateral-to-principal ratio instead of LTV, and the standard 200% CTP means $300,000 in Bitcoin supports a $150,000 loan. In conventional terms that is 50% LTV, and 50% is also the ceiling.

CoinRabbit takes more than 350 assets and lets the borrower set LTV anywhere from 50% to 90%. APR starts at 11.95%, stays fixed for the life of the loan, and moves with the LTV selected. A loan paid into the CoinRabbit Wallet carries no origination fee, while routing the payout to an external address adds a network fee. The liquidation threshold tracks the configuration chosen, sitting between 80% and 95%.

Open-ended loans have no maturity date, so a position stays open as long as coverage holds, with interest accruing monthly and settled on full or partial repayment, while fixed-term loans run a set period, typically 30 days, and price below the open-ended equivalent at the same LTV. Unchained publishes one product at one price, and CoinRabbit publishes a range and leaves the configuration to the borrower.

Collateral management and custody

Custody is the argument Unchained leads with, and it is a serious one. No single party can move the Bitcoin alone, and the borrower can verify the collateral on chain at any time using the key its own company controls. Rehypothecation is blocked by the architecture.

The bill for that arrives in operations. The vault has to be set up, keys generated and stored, a third-party agent coordinated with, and the borrower has to keep running a key-management process for as long as the loan is open, which is part of why funding starts at two business days. The model is built for a treasury function that already has such a policy written down.

CoinRabbit holds collateral in segregated cold multisig wallets under the same no-rehypothecation principle, with client assets kept apart and never lent out to generate yield. The platform puts its effort into monitoring instead: automatic top-ups when coverage slips, real-time position tracking in the dashboard, and risk-zone alerts by email and SMS as coverage approaches the liquidation threshold.

Where a mandate requires the borrower to hold a key to its own collateral, Unchained’s vault is the product and the setup cost is the price of admission. Where the practical question is whether collateral is segregated, un-reused and verifiable, both platforms answer it. The difference comes down to what the arrangement takes to run.

Unchained Capital vs CoinRabbit: Fees and cost structure

Unchained’s headline is simple to model: 12% interest, 14.18% APR, and a 2% origination fee already inside that APR. There is nothing to configure and nothing hidden, and for a treasurer building a payment schedule the predictability counts. At the same time the rate sits at the upper end of the market, and interest-only payments every 30 days mean the loan is serviced throughout the term before the principal lands as a balloon at the close. The pricing page lists the exceptions around it: $10 for a late payment, $15 for a returned ACH, and 2% of the sale if collateral has to be liquidated.

CoinRabbit’s cost follows the borrower’s own choices: a loan paid into the CoinRabbit Wallet carries no origination fee, so the quoted APR is the cost of the loan, while sending the proceeds to an external address adds a network fee. Fixed-term pricing sits below open-ended pricing at the same LTV, and the rate rises from the 11.95% floor as leverage increases.

Take $200,000 as the reference, an amount both platforms will write. At Unchained it is a commercial facility at 14.18% APR with $4,000 of origination folded into the balance, 12%  interest payments to service, and $400,000 of Bitcoin locked into the vault for the duration. At CoinRabbit the same $200,000 can be drawn at 11.95% APR at the same 50% LTV, against a collateral set that reaches well beyond Bitcoin, with no origination fee on a payout to the wallet and no fixed repayment calendar if the open-ended structure is used. Raise the LTV and the collateral requirement falls well below $400,000, at a higher rate.

Supported assets and features

Unchained is a Bitcoin company and the loan book reflects it, taking Bitcoin as the only collateral it lends against. A borrower holding ETH, SOL or a mid-cap position has to convert into Bitcoin first, which changes the exposure and, in most jurisdictions, counts as a taxable disposal. What sits around the loan is depth rather than breadth: vaults, a Bitcoin IRA, a trading desk, inheritance planning and trust services, all Bitcoin-native.

CoinRabbit accepts 350+ assets, so the position a borrower already holds is the position that gets pledged. Around it sit automatic collateral top-ups, real-time health monitoring and risk-zone alerts by email or SMS, plus a white-labeled lending API for partners embedding crypto-backed borrowing into their own products. Swaps and yield accounts live in the same account, so collateral, proceeds and repayment do not have to move between platforms.

Borrowing experience and access

Unchained’s process is a commercial one and looks like it. A business entity, a commercial loan application, onboarding, key generation and vault setup all come before money moves, and funding starts at two business days. By commercial lending standards that is quick, and it also assumes a company with a treasury function on the other side of the paperwork.

CoinRabbit completes a loan end to end in about 10 minutes, and those 10 minutes are the entire process. The collateral underwrites the loan, so there is no approval stage, no credit file to pull and no entity to register. Timings quoted elsewhere in this market usually measure the disbursement after approval, which is a different thing being counted.

Borrowers who want to see the mechanics before committing size can run a test-size loan first, take the full flow end to end, and watch how collateral, the dashboard, the alerts and repayment behave before pledging a big position. Support is human and available around the clock for every client.

Unchained Capital vs CoinRabbit: Programs for larger clients

Both platforms run a dedicated track at the top of the book, and they draw the line in different places.

Unchained’s institutional desk starts at $5 million and serves family offices, funds and institutional borrowers, where size, terms and structure are discussed case by case rather than read off a rate card.

CoinRabbit’s Private Program opens at $500,000 in capital. Members get proactive assistance from a private manager, personalized rates and custom loan terms, a loan recovery option, portfolio resilience through cross-collateralization, direct transfers to bank accounts, OTC trading and access to exclusive events within a curated circle. The client base runs to high-net-worth investors, family offices, fintech companies, institutional investors, hedge funds and Bitcoin mining firms.

Unchained vs CoinRabbit review: Comparison table

Unchained vs CoinRabbit: Which one fits you

Unchained fits a company that holds Bitcoin, borrows $150,000 or more, and treats holding a key to its own collateral as non-negotiable. That mandate is real, usually where a board or an auditor has written it down, and for the firms that carry it the higher rate and the multi-day setup are worth paying.

CoinRabbit fits the borrowers whose binding constraint is something else: assets other than Bitcoin, liquidity needed in minutes, leverage above 50%. It also fits anyone who would rather hold an open-ended position than a twelve-payment schedule with a balloon at the end.
