 ## [Unreleased]
 
+### Added
+
+- Add `mapRampsOrder` for mapping ramps buy/sell orders into the shared activity item shape, and add `rampBuy`/`rampSell` to `ActivityKind` and `ActivityItem` ([#9650](https://github.com/MetaMask/core/pull/9650))
+  - Add an optional `id` field to activity items for items (like pending ramp orders) that may not yet have an on-chain `hash`.
+
 ## [1.2.1]
 
 ### Changed
