Galactic Credit Standard (Earth-2356)

The Galactic Credit Standard, simply called a credit or abbreviated to cred, colloquially referred to as Republic Dataries, and later known as the Imperial Credit, is the main currency in use in the galaxy since the time of the Galactic Republic.

The galactic credit standard was established on Sojourn. From its inception, the credit was backed by the immense wealth of the planet Muunilinst and the InterGalactic Banking Clan (IGBC). During the Clone Wars, the IGBC backed the currencies of both sides.

One tenth of a credit is called a decicred.
