It depends on some definitions, but I've read that's not the case. Jericho region is said to have been exclusively barter based until ~7,500 BC And it depends on what you mean by "depended on". The central authorities of the day maybe preferred to rely on financial tools, but the people themselves performed a non-insignificant amount of commerce using barter. "2 knicks on this clay tablet reminds me that I gave Tom two bushels of wheat, and Tom will return to me 2 pelts," contrived example to make the point aside, such scenarios as I understand it, were (and are) pretty common. It depends on what context you're looking from. Bankers might say it's a ridiculous, outdated notion, and sell the idea it's never really existed. Poor people might say yeah well, it's all we really have.
