Coinbase opened bitcoin-backed USDC loans through Morpho

Coinbase announced on January 16, 2025 that it was beginning a gradual rollout of bitcoin-backed loans powered by Morpho, an open-source lending protocol on the Base network. Eligible Coinbase customers could pledge bitcoin and borrow USDC without navigating Morpho directly.

The development mattered because a major centralized cryptocurrency exchange was placing decentralized lending infrastructure behind a familiar retail interface. Coinbase handled the customer-facing workflow, while collateral and borrowing were routed through onchain smart contracts. That model offered a practical test of whether open protocols could become infrastructure for mainstream financial products without requiring every user to manage a separate wallet and protocol interface.

How the product worked

Coinbase said the loans would become available over the following months to customers in the United States, excluding New York. The initial product used bitcoin as collateral and allowed eligible customers to borrow as much as 100,000 USDC, depending on the amount of collateral pledged. Coinbase planned to begin in its mobile application and later extend access to web browsers.

When a customer confirmed a loan, Coinbase said the pledged BTC would be converted into Coinbase Wrapped Bitcoin, or cbBTC, at a 1:1 ratio and transferred to a Morpho smart contract on Base. Morpho would then disburse USDC, with the proceeds appearing in the customer’s Coinbase account.

The interest rate was not fixed. Coinbase said Morpho calculated a variable rate from conditions in the onchain lending market, with the rate capable of changing as new Base blocks were produced. The loans had no fixed repayment schedule, but interest continued to accrue.

A centralized interface over open infrastructure

The arrangement joined several products connected to Coinbase: bitcoin held through the exchange, cbBTC as its wrapped representation, USDC as the borrowed asset, Base as the settlement network and Morpho as the lending protocol. CoinDesk described Morpho as the largest lending platform on Base at the time and reported that Coinbase was embedding Morpho’s borrowing markets into its interface rather than creating an entirely separate lending system.

That distinction was institutionally important. Borrowing USDC against wrapped bitcoin was already possible through onchain applications. The January 16 launch reduced the operational steps for Coinbase customers and placed account access, conversion and loan monitoring inside one application. Morpho retained the open smart-contract layer beneath that experience.

Coinburn’s interpretation is that the integration represented distribution as much as product invention. Coinbase was not introducing crypto-collateralized lending itself; it was packaging an existing onchain mechanism for a much larger customer channel. Morpho characterized the integration as a model that other exchanges, financial-technology companies and banks could eventually follow, but that was the protocol developer’s contemporaneous expectation rather than a verified outcome on January 16.

Liquidation remained the central risk

The simplified interface did not remove the economic risks of overcollateralized lending. Coinbase said liquidation would be triggered if the outstanding loan and accrued interest reached a specified threshold relative to the collateral’s value. A decline in bitcoin’s price, growth in accrued interest or both could therefore place pledged cbBTC at risk.

CoinDesk reported that borrowers had to post collateral worth more than the USDC they received and that Coinbase planned to send warnings through its application when a position approached liquidation. Those warnings could help users monitor a loan, but they did not guarantee that liquidation would be avoided during volatile or rapidly moving markets.

The event-day record established a rollout, not adoption at scale. Neither Coinbase nor Morpho supplied January 16 figures for completed loans, collateral deposited, active borrowers or loan volume. The verified significance was structural: Coinbase had connected its retail interface to public lending infrastructure, turning a DeFi borrowing process into an exchange-distributed product while leaving variable rates and collateral liquidation intact.
