Rollback Protection

Steam trade rollbacks happen. We handle them automatically so you don't have to worry.

Automatic Refunds

If Steam rolls back a trade, our system automatically reverses the charge. No support tickets needed.

Smart Fault Detection

Our system accurately detects if the buyer or seller caused the rollback. You only pay for items you actually receive.

Instant Resolution

Issues are detected and fixed within minutes, so your automated buying can continue without interruption.
