Changed

Centralized Wallet Service

All P2P trading wallet operations now use the centralized wallet service.

• Changed trade releases and cancellations to run as a single all-or-nothing operation, so a failure part-way through cannot leave funds in limbo
• Changed fund releases to be protected against duplicates, so a retried release cannot pay out twice
• Changed concurrent operations on the same trade to be serialized against each other
• Changed trade amount and fee arithmetic to be precision-safe

P2P Trading Operations

• Changed trade release to use atomic wallet operations for fund transfers
• Changed trade cancellation to release funds back to the seller correctly
• Changed offer creation to lock funds through the centralized service
• Changed dispute resolution to settle through the centralized wallet service, with an audit trail

Notifications

P2P trading notifications now use the new multi-channel notification service.

• Changed notification delivery to cover the IN_APP, EMAIL, SMS and PUSH channels
• Changed notifications to respect each user's own channel preferences
• Changed notifications to be protected against duplicates, so a retried operation does not notify twice
• Changed all P2P notification types over to the new service, covering new trade requests, payment confirmations, trade releases, disputes opened and resolved, offer status changes and rating requests
