IndoBlox is an Indonesian marketplace and escrow service for buying and selling Robux, Roblox’s virtual currency. Rather than selling Robux directly, the platform connects buyers with verified sellers and holds payment until the buyer confirms that the Robux have arrived. Buyers can pay using QRIS and choose from several delivery options, including username-based delivery, Gift In Game, and Via Login. Username delivery requires only the recipient’s username, while the login option requires temporary account access; IndoBlox says login details are encrypted, available only to the seller handling the order, and automatically deleted after completion.

The service operates 24 hours a day and aims for fast delivery. For username orders, sellers must complete delivery within 30 minutes or the order is reassigned. If delivery fails, IndoBlox says it can redirect the order to another seller. Sellers must pass identity verification before accepting orders, and the platform states that its escrow process is intended to protect buyers. IndoBlox is part of GrowTech and is not affiliated with Roblox Corporation.
