Coinbase Borrow

Coinbase Borrow – Overview

Most exchange-run lending products keep everything in-house, your collateral sits wherever the exchange decides to put it, and you just have to trust that’s handled responsibly. Coinbase Borrow does something a little different. It’s built on top of Morpho, a decentralized lending protocol running on Base, the Ethereum layer-2 network Coinbase itself helped build. The app experience feels entirely centralized, but the actual mechanics happen on a public blockchain.

Here’s what happens under the hood. When you borrow against your Bitcoin, that BTC first gets converted into cbBTC, Coinbase’s own tokenized representation of Bitcoin, and deposited into a Morpho smart contract rather than sitting in a Coinbase custodial wallet. That distinction matters. Since the position lives on-chain, it’s inherently visible and auditable in a way that traditional CeFi custody usually isn’t, and Coinbase isn’t in a position to quietly rehypothecate collateral it never actually holds.

Pricing here works differently from a typical fixed-rate CeFi loan too. Interest rates aren’t set by Coinbase directly, they float based on supply and demand within Morpho’s lending pools, adjusting roughly every few seconds as new blocks get created on Base. You’ll see the going rate at the moment you take out the loan, but expect it to shift over time along with market conditions rather than staying locked the way a fixed-term loan would.

There’s no repayment schedule to worry about either. No monthly due dates, no minimum payments, just an LTV ratio you need to keep in check. The system requires a minimum collateral ratio of 133%, which works out to a maximum LTV somewhere around 75%. Push your position too close to an 86% LTV and automatic liquidation kicks in, selling off just enough BTC to cover the loan balance and a penalty fee, with whatever’s left over returned to your account. Coinbase does offer a loan protection feature that lets you set up automatic collateral top-ups before things get to that point, which is worth turning on if you’d rather not babysit your LTV constantly.

Borrowing limits are substantial, up to $5,000,000 in USDC depending on how much BTC you’re willing to post as collateral. The whole thing is currently limited to US users, and New York residents aren’t included yet, though Coinbase has signaled plans to expand availability further.

One quirk worth knowing: Coinbase’s terms don’t let you use the borrowed USDC to trade directly back on the Coinbase platform itself. You can, however, move it anywhere else in the broader crypto ecosystem, or simply hold it and earn yield while you figure out what to do with it.
