Coinbase recently launched a fixed-rate Bitcoin-backed loan product powered by Morpho Midnight, offering users a way to borrow USDC without selling their BTC. Unlike traditional variable-rate loans, borrowers can lock in both the interest rate and repayment date at the time of loan origination—adding predictability to their financing.
The platform now offers two distinct lending models: one driven by market dynamics with fluctuating rates, and another with fixed terms via Midnight. The existing floating-rate service has over $1.4 billion in outstanding loans, backed by approximately $3 billion in collateral. This strong foundation reflects growing user adoption as Coinbase expands into structured credit markets.
Coinbase manages the customer-facing experience, while Morpho provides the underlying lending infrastructure. All transactions settle on the Base blockchain. This expansion builds on Coinbase’s prior moves, including launching USDC lending for UK users and integrating Solana into its on-chain lending offerings.
Jacob Frantz, Head of Revenue & Investment Products at Coinbase, stated: “Coinbase Borrow lets customers access liquidity without selling assets. With fixed-rate lending, they gain more control over their financial planning.”
Morpho introduced Midnight in July as an alternative to dominant variable-rate DeFi models. Instead of relying on algorithmic rate adjustments based on liquidity, Midnight uses a chain-based order book where lenders and borrowers submit bids. The resulting matched price determines the interest rate—giving borrowers upfront clarity on repayment obligations.
As the first major platform to scale Midnight, Coinbase currently sees around $30 million in deposits across the protocol. In contrast, Morpho Blue, the established variable-rate system, hosts about $5.2 billion in outstanding loans and $16 billion in total deposits across all integrations—highlighting the early stage of Midnight’s development.
Coinbase has not disclosed specific fixed rates. Instead, pricing is determined by supply and demand through the public order book, allowing market forces to set borrowing costs.
Initially, loan terms are short-term, with options to repay by the last Friday of the current or next month. Failure to repay by the deadline results in automatic liquidation of the collateral. This contrasts with the flexible repayment window of Coinbase’s floating-rate loans, emphasizing a trade-off between predictability and flexibility.
For BTC holders, this model remains attractive: maintaining exposure to Bitcoin while accessing USD liquidity. Coinbase is also extending the concept beyond personal finance—launching a dedicated program enabling eligible U.S. homebuyers to use BTC as down payment collateral.
The real test lies in whether predictable terms can attract users beyond typical crypto traders. Fixed interest and clear maturity dates bring chain-based lending closer to conventional credit products—potentially appealing to corporate treasuries, institutional borrowers, and structured financing needs requiring cost certainty.
Morpho has identified potential applications in tokenized real-world assets (RWA) and structured credit, suggesting future integrations. While no additional partners or launch timelines have been announced, Coinbase currently serves as the clearest real-world case study. With over $1.4 billion in active floating-rate loans, a significant shift toward fixed-term options could signal a pivotal evolution in on-chain lending—from volatile DeFi markets to stable, predictable financial instruments.
