Razer is attempting to create "a complete gamer economy," via its zVault ecosystem. The firm's zVault is a secure digital wallet for gamers with zGold and zSilver virtual currencies for payments and rewards. Razer says that users will pay securely for digital items using zGold (100 zGold = US$1) while zSilver is earned from purchases made using zGold, and through Razer software use, such as Razer Cortex and Arena.
