Diablo 3 Has Gold Currency — But It's a Utility Resource, Not Primary Gear Currency

Yes, but it's not the primary gear currency. Diablo III uses Gold for:

• Repairs (durability restoration)
• Crafting (artisan fees, combining gems)
• Vendor purchases (potions, basic materials, follower items)
• Gambling (Kadala—Blood Shards are the currency; Gold is the fee)
• Transmogrification (cosmetic appearance changes)

Primary Gear Currencies

• Blood Shards: Earned from Rifts/Greater Rifts; spent at Kadala for random legendaries/sets.
• Crafting Materials: (Arcane Dust, Veiled Crystals, Forgotten Souls, etc.) from salvaging; used to craft/reroll gear at the Blacksmith/Mystic.
• Gold: Still needed for crafting fees and gem upgrades.

Gold is a utility resource, not a "buy gear" currency. The economy revolves around Shards and Mats for progression.
