Estonia's monetary unit, which is the Euro, is the main currency used in the country since it adopted the single European currency in 2011. Other synonyms for the Estonian monetary unit could be the Estonian Euro or simply the Euro in Estonia. Prior to this, Estonia used its own national currency, the Kroon, which was replaced by the Euro due to the country's membership in the European Union. Today, the Euro is widely accepted in Estonia, and its use makes financial transactions between Estonia and other European countries smoother and more convenient.
