USDC Polygon · United States — Currency exchange map

The US dollar (USD) is the national currency. Euros, British pounds, Canadian dollars, Mexican pesos and Japanese yen are exchanged most often. New York City, Los Angeles, Miami, Chicago, San Francisco and Houston have the most offers.
There are fewer exchange offices in the US than in Europe or Asia. They operate at international airports, in tourist districts and malls, and some banks exchange currency only for their own customers. In the United States, listings let you swap USDT or USDC for US dollars or exchange euros directly with another person.
