### Changed

- Deliver HyperLiquid positions, orders, and account/spot balance via per-DEX `clearinghouseState` and `openOrders` subscriptions on all paths, removing the dependency on the deprecated `webData2` snapshot channel ([#9078](https://github.com/MetaMask/core/pull/9078))
- The non-HIP-3 (main-DEX-only) user data path previously used `webData2`, which HyperLiquid is throttling to a 15s push interval and deprecating. It now uses the same sub-second per-DEX subscriptions as the HIP-3 path, with `webData3` retained only for open-interest caps (not latency-sensitive).
- Surface late order completions via trace `reason: 'late_success' | 'late_error'` ([#21217](https://github.com/MetaMask/core/pull/21217))
- Bump `@metamask/controller-utils` from `^12.1.0` to `^12.2.0` ([#9058](https://github.com/MetaMask/core/pull/9058), [#9083](https://github.com/MetaMask/core/pull/9083))

- Fix `late_error` never being emitted in the `placeOrder` catch path when a provider call succeeded past `PlaceOrderTimeoutMs` but a subsequent step threw; the trace `reason` now correctly reflects `'late_error'` whenever the submission threshold was exceeded, regardless of where the exception originated ([#8994](https://github.com/MetaMask/core/pull/8994))
