Changed

Wallet handling

All payment gateway wallet operations now go through the platform's central wallet service:

• All-or-nothing crediting: a deposit either completes fully or not at all — it can no longer be left half-applied.
• No duplicate credits: if a payment provider sends the same confirmation twice, the customer is credited once.
• Safe under load: two payments landing at the same instant no longer interfere with each other.
• Exact amounts: payment amounts are calculated without rounding drift.

Payment gateways

• Changed every fiat deposit confirmation to use the central wallet service.
• Changed error messages to be consistent across all payment gateways.
• Changed the record kept of every payment operation to be clearer for reconciliation.

Gateway operations

• Refunds: applied all-or-nothing, like deposits.
• Fees: properly tracked against each payment.
• Payouts: recorded with a full audit trail.

Notifications

Gateway notifications now use the new multi-channel notification service:

• Multiple channels: notifications can be sent in-app, by email, by SMS and as push notifications.
• Payment notifications: deposit confirmations and refund alerts.
• No duplicates: a repeated provider confirmation does not produce a second notification.
• User preferences respected: each customer's chosen notification channels are honoured.
