## [Unreleased]

## [16.2.0]

### Added

- **BREAKING:** Add `ORDER_MARGIN_MODE_INVALID`, `ORDER_MARGIN_MODE_UNSUPPORTED`, `ORDER_MARGIN_MODE_POSITION_OPEN`, and `ORDER_MARGIN_MODE_ORDER_OPEN` to the exported `PerpsErrorCode` union. ([#10136](https://github.com/MetaMask/core/pull/10136))
- Consumers with exhaustive `Record<PerpsErrorCode, …>` maps must add all four entries, including Mobile's `app/components/UI/Perps/utils/translatePerpsError.ts` and Extension's `ui/components/app/perps/utils/translate-perps-error.ts`. Existing callers that omit `marginMode` keep the same runtime behavior.
- Add `ORDER_MARGIN_MODE_INVALID`, `ORDER_MARGIN_MODE_UNSUPPORTED`, `ORDER_MARGIN_MODE_POSITION_OPEN`, and `ORDER_MARGIN_MODE_ORDER_OPEN` to the exported `PerpsErrorCode` union. ([#10136](https://github.com/MetaMask/core/pull/10136))
- Expanding `PerpsErrorCode` is a minor. Clients should handle unknown codes in a catch-all rather than an exhaustive `Record<PerpsErrorCode, …>`. Existing callers that omit `marginMode` keep the same runtime behavior.
- Add explicit HyperLiquid `OrderParams.marginMode` selection with market-capability and open-position/order/TWAP guards, and expose the venue's `MarketInfo.marginMode` capability. ([#10136](https://github.com/MetaMask/core/pull/10136))

## Error codes

`PERPS_ERROR_CODES` / `PerpsErrorCode` are the structured codes returned to
the UI for translation. New codes are additive and ship as a minor. Clients
should keep a catch-all for unrecognized codes instead of an exhaustive map,
so a bump does not fail to compile when a code is added.

## Explicit HyperLiquid margin mode

Pass `marginMode: 'cross'` or `marginMode: 'isolated'` with an integer `leverage`
