Circle co-founder and CEO Jeremy Allaire published a lengthy rebuttal on X on July 1 to the pitch behind OUSD, the stablecoin launched by the Open Standard consortium, arguing that USDC's advantages in distribution, liquidity and regulatory licensing are not easily replicated.

Open Standard's Open USD aims to let partners keep reserve income and eliminate minting fees, challenging Circle's USDC.

The forthcoming Open USD has more than 100 major supporters onboard, including Coinbase—a key backer of Circle’s USDC.
