Government-issued currency, such as USD or EUR, not backed by a physical commodity.
Fiat refers to government-issued currency that is not backed by a physical commodity like gold or silver. Instead, its value comes from government regulation and public trust. Examples include the US Dollar (USD), Euro (EUR), British Pound (GBP), and Japanese Yen (JPY).
Fiat currencies serve as the primary medium of exchange in the global economy and remain the default on-ramp for purchasing cryptocurrencies.
Characteristics of Fiat Currency
Centralized issuance: Controlled by national governments and central banks
Inflationary: Money supply can be expanded through monetary policy
Universal acceptance: Used for everyday payments and commerce
Legal tender: Must be accepted for debts within a country
Fiat contrasts directly with cryptocurrency, which operates on decentralized blockchain networks.
