The Czech koruna (CZK) is the national currency; the country has not adopted the euro, although euros are sometimes accepted in tourist spots. Euros, US dollars, British pounds, Swiss francs and Polish zlotys are exchanged most often. Prague has the most offers, followed by Brno, Ostrava, Plzeň, Liberec and Olomouc.
Central Prague has many exchange offices, and their rates and fees vary widely, so it is worth checking the options on the map in advance. P2P offers help you swap USDT or USDC for korunas.
