Australian stablecoin payment startup Stables has announced a partnership with Mastercard to expand its business to Europe and the UK. Co-founder of the company, Bernado Billota, said that this indicates that assets pegged to the US dollar are gradually becoming mainstream. The new partnership will allow Stables users to make purchases using Circle's USDC. USDC is accepted in 27 European countries that accept Mastercard and can be paid for through digital providers such as Apple and Google Pay.
