Vault
Server-side receipt validation for Apple, Google, and Steam — one API. Fraud filters baked in. Support panel with transaction history and one-click refunds.
What Vault does.
Vault verifies. Market sells. They are not the same module.
Apple receipts
App Store Server Notifications v2 + StoreKit 2 signed transactions. Sandbox and prod side-by-side.
Google Play
Play Billing subscriptions and one-time purchases. Server verification, voided-purchases reconciliation.
Steam
ISteamMicroTxn + web hooks. PC-first F2P, non-Steam deposits, gifts.
Fraud filters
Velocity, device fingerprint, graph signals. Auto-quarantine suspicious receipts until reviewed.
Refund panel
Support sees full history per player. One click reverses the grant, updates inventory, emits to Lens.
Revenue in Lens
Every verified receipt fires an event — retention-by-payer, LTV, pack-level economics, no ETL.
