According to Coinbase, Better’s mortgage structure uses Bitcoin or USDC as collateral for a separate loan tied to a conforming mortgage, with fixed rates, a single payment, and no margin calls.
Coinbase said on June 26 that Better introduced a mortgage service backed by Bitcoin or USDC that requires 250% collateral and combines a crypto-backed loan with a standard mortgage into one monthly payment. According to Coinbase, the structure uses a fixed-rate design and does not include margin calls. The announcement also says the mortgage is backed by Fannie Mae. The update adds a new official statement from Coinbase but does not materially change the previously reported core structure of the product, which pairs crypto collateral with a conventional home loan for eligible borrowers.
