“This is a wrapper for the USDC reserve that brings benefits of that wrapper to the USDC and the ecosystem,” said Circle Chief Financial Officer Jeremy Fox-Geen, in an interview with CoinDesk. All of the company’s short-term Treasury assets will be phased into the fund, though the cash reserve — about 20% of the total — will still be held in partner banks, Fox-Geen said, because it allows for customers to more easily redeem USDC around the clock.
