How Coinbase works
Coinbase's bitcoin-backed loan is a managed front-end over Morpho, a DeFi lending protocol, running on the Base network. When you borrow, Coinbase converts your BTC to cbBTC (its wrapped, 1:1 bitcoin token) and locks it in a smart contract, then lends you USDC against it. There are no fixed repayments or due dates — you repay whenever you like and reclaim your cbBTC (which converts back to BTC). It's US-only and currently excludes New York.
Rates & fees
The borrow rate is variable, advertised "as low as 5%" and set algorithmically by the underlying Morpho market's utilization — generally in the ~3–7% band. There are no origination or monthly fees; you pay the Base network gas (largely abstracted by Coinbase) plus the variable interest. Because the rate floats, your cost can rise if market demand for USDC spikes.
LTV & liquidation
You can borrow up to a 75% LTV (a minimum 133% collateral ratio), and choose any level below that. Liquidation triggers at 86% LTV, with a 4.38% liquidation penalty; Coinbase offers an optional auto-top-up "loan protection" feature. The higher allowed LTV is more generous than shared-pool DeFi, but borrowing near the cap on a volatile asset is risky — keep a buffer.
Custody & safety — why we rate Coinbase Medium relative risk
Source: Coinbase crypto-backed loans (cbBTC via Morpho on Base) ↗
Coinbase itself is a large, regulated, public company — but the loan is non-custodial at the protocol layer: your collateral sits in a Morpho smart contract, not on Coinbase's balance sheet, and is not rehypothecated. We rate it Medium rather than LOW because you're exposed to smart-contract risk and tokenized-BTC (cbBTC) risk on top of the loan — the collateral is a wrapped representation of bitcoin, not native BTC. See the risk methodology.
What a $50,000 Coinbase loan costs
At ~5% this is roughly half the cost of a typical CeFi loan — the price you pay is holding cbBTC rather than native bitcoin while the loan is open. Figures illustrative; the rate floats.
Pros & cons
Strengths
- Low variable rate (~5%) from a regulated brand
- No origination or monthly fees, no due dates
- High borrow limit (up to ~$5M)
- Simple UX over a DeFi protocol
Trade-offs
- Your BTC becomes cbBTC — tokenized, not native
- Smart-contract risk (Morpho on Base)
- Variable rate can rise with utilization
- US-only, excludes New York
Who Coinbase is best for
Coinbase suits borrowers who want a low rate and a familiar interface and are comfortable with their bitcoin being held as cbBTC in a smart contract. If you insist on native bitcoin, a CeFi lender like Strike or Ledn is the better fit. To weigh tokenized vs native BTC, see how to compare lenders.
FAQ
What is Coinbase's Bitcoin loan interest rate?
A variable rate advertised as low as 5%, set by the underlying Morpho market — generally in the 3–7% range. No origination or monthly fees; you pay Base gas plus interest.
Does Coinbase use my real Bitcoin?
Your BTC is converted to cbBTC, a tokenized 1:1 representation, and locked in a Morpho smart contract on Base. It converts back to BTC when you repay.
When does Coinbase liquidate?
Liquidation triggers at 86% LTV with a 4.38% penalty. Max initial LTV is 75%, and optional auto-top-up can help avoid it.
Is the Coinbase loan safe?
It's non-custodial (collateral in a smart contract, not rehypothecated) from a regulated operator, but carries smart-contract and tokenized-BTC risk. We rate it MED.
