First Fannie Mae-backed Bitcoin mortgage funded in U.S., Coinbase says

Coinbase says the first Fannie Mae-backed mortgage collateralized by Bitcoin has officially closed in the United States. This marks a major step toward integrating crypto assets into mainstream housing finance.

In a June 4 post, Coinbase said the mortgage was originated and serviced by Better using Coinbase infrastructure, with nationwide rollout expected later this summer.

The announcement follows Coinbase and Better’s March unveiling of a crypto-backed mortgage program. It is designed to allow borrowers to use Bitcoin or $USDC holdings as collateral while retaining exposure to their digital assets.

How the mortgage structure works

The product does not involve purchasing homes directly with Bitcoin.

Instead, borrowers pledge crypto assets as collateral for a separate loan used to fund the mortgage down payment.

Under the structure outlined by Coinbase in March:

• borrowers receive a standard Fannie Mae mortgage on the home,
• plus a second collateralized loan tied to Bitcoin or $USDC holdings.

The crypto collateral remains in custody throughout the life of the loan and is returned upon repayment of the obligation.

Coinbase previously said borrowers can access:

• 15-year,

• and 30-year fixed-rate mortgage options through the program.

The company also stated that Bitcoin’s price volatility does not directly affect mortgage terms under Better’s structure.

Coinbase pitches crypto as housing collateral

Coinbase framed the mortgage rollout as part of a broader effort to integrate digital assets into real-world financial infrastructure.

The company argued that many crypto holders previously faced a difficult choice when buying homes.

By allowing borrowers to pledge digital assets rather than fully liquidate them, Coinbase said crypto-backed mortgages could expand access to homeownership while preserving long-term investment exposure.

Fannie Mae link gives the launch institutional weight

One of the most notable parts of the rollout is the involvement of Fannie Mae-backed conforming mortgage structures.

That connection moves the product beyond a niche crypto lending experiment. It ties it directly into regulated U.S. housing finance infrastructure.

Coinbase described the mortgages as “conforming” products that benefit from the same Fannie Mae backing used across traditional mortgage markets.

Housing finance may now become another major category in which digital assets interact more directly with regulated financial systems.

Risks and unanswered questions remain

Despite the milestone, the model still carries significant risks and open questions.

Crypto prices remain highly volatile, and the structure depends heavily on collateral management requirements. Coinbase previously said Bitcoin-backed down payment loans require collateral worth at least 250% of the loan amount.

Questions also remain around:

• long-term regulatory treatment,
• housing market stress scenarios,
• borrower protections,
• and how scalable crypto-backed mortgage underwriting may become over time.

The nationwide rollout later this summer may offer a clearer picture of whether demand for the product extends beyond early crypto-native adopters.

Final Summary

• Coinbase said the first Fannie Mae-backed mortgage funded with Bitcoin collateral has officially closed in the United States.
• The crypto-backed mortgage structure allows borrowers to pledge Bitcoin or $USDC for down payment financing while keeping exposure to their digital assets.
