Đồng is a traditional Vietnamese currency unit, historically used in Vietnam before the introduction of the Vietnamese đồng (VND) in 3rd century AD. The term "đồng" originally referred to bronze coins and has evolved over time to represent various forms of currency. Today, the Vietnamese đồng is the official currency of Vietnam, issued by the State Bank of Vietnam. It is subdivided into smaller units called "hào" and "xu," although these smaller denominations are rarely used in daily transactions. The symbol for the đồng is "₫."
