 ### Added
 
 - Added `orders: RampsOrder[]` to controller state with persistence, along with crud methods([#8045](https://github.com/MetaMask/core/pull/8045))
+- Added `apiMessage` property to `TransakApiError` to surface human-readable error messages from the Transak API (e.g. OTP rate-limit cooldown)
 - Added `RampsController:orderStatusChanged` event, published when a polled order's status transitions ([#8045](https://github.com/MetaMask/core/pull/8045))
+- Added real-time order status tracking for Transak orders via Pusher WebSockets ([#8075](https://github.com/MetaMask/core/pull/8075))
+  - Added `TransakService:orderUpdate` event to notify when WebSocket events are received
+  - Added `subscribeToOrder()`, `unsubscribeFromOrder()`, and `disconnectWebSocket()` methods to `TransakService`
+  - Added `subscribeToTransakOrderUpdates()` method to `RampsController` for bootstrapping WebSocket subscriptions on app restart
+  - Added `PusherFactory`, `PusherLike`, and `ChannelLike` types for dependency injection
+  - Exported new action types: `TransakServiceSubscribeToOrderAction`, `TransakServiceUnsubscribeFromOrderAction`, `TransakServiceDisconnectWebSocketAction`
