1233.0.0

@metamask/perps-controller 16.0.0

Added

• Add reduce_only intent to every Perp Trade Transaction lifecycle event while preserving canonical order_type values (#10091)
• Add POSITION_NOT_FOUND as the provider-neutral error code for operations targeting a position the venue no longer holds (#10083)

Changed

• Bump @metamask/transaction-controller from ^69.7.0 to ^69.8.0 (#10080)
• Bump @metamask/utils from ^11.11.0 to ^11.12.0 (#10076)

Removed

• BREAKING: Remove all MYX protocol support (#10038)
  • PerpsProviderType is now 'hyperliquid' | 'lighter'. Drop any 'myx' case from exhaustive switches, and stop passing activeProvider: 'myx' or providerId: 'myx'.
  • Removes the MYXCredentials type and the providerCredentials.myx option from PerpsControllerOptions, all MYX_* exports (chain ids, endpoints, decimals, fees, asset configs), the getMYXChainId / getMYXHttpEndpoint helpers, the fromMYX* / toMYX* converters, the MYX-only USDT_BNB_TESTNET / USDT_BNB_MAINNET addresses, and PROVIDER_CONFIG.MYX_TESTNET_ONLY.
  • No migration is required for stored client state: an activeProvider value naming a removed venue falls back to 'hyperliquid' and is rewritten on next launch.
  • The perpsMyxProviderEnabled remote feature flag and the MM_PERPS_MYX_PROVIDER_ENABLED env override are no longer read; clients can retire both.
  • HyperLiquid and Lighter behavior is unchanged.
