Synced from mobile PR #26110: - toggleTestnet: check InitializationState.Failed after init() and rollback isTestnet on failure (matching switchProvider pattern) - depositWithConfirmation: replace never-resolving promise with Promise.resolve(transactionMeta.id) when placeOrder=true
Hoist currentDepositId before try block so it is accessible in the outer catch. When a pre-submission error occurs (e.g. missing networkClientId), the deposit request is now marked as 'failed' instead of staying permanently 'pending' in state.
Prevent standalone preload from leaking WebSocket providers by caching the HyperLiquidProvider instance across standalone calls and cleaning it up at lifecycle boundaries (init, disconnect, toggleTestnet, etc.). Reorder switchProvider() to check "already active" before validating the providers map, so it returns a no-op success before init().
Add uuidv4() fallback for currentDepositId which TypeScript cannot narrow inside the update() callback after the variable was hoisted to let binding with string | undefined type.
The base tsconfig.json was missing project references that tsconfig.build.json already had, causing TS2345 errors for imports like @metamask/account-tree-controller during type checking.
Jest exits with code 1 when no test files exist. Add a minimal placeholder test in tests/ (outside src/ so the Mobile sync script does not delete it) and scope collectCoverageFrom to that file only, preventing 0% coverage failures on the synced source.
…cription Register all 34 PerpsControllerActions via registerMethodActionHandlers() so inter-controller communication works through the messenger in core. Store the RemoteFeatureFlagController:stateChange subscription handle and clean it up in disconnect() to prevent leaks.
… and account switch - Remove feature-flag unsubscribe from disconnect() so geo-blocking and HIP-3 flag changes keep propagating after reconnect cycles - Add deposit request lifecycle tracking for the deposit+order flow so requests transition from pending to completed/failed/cancelled - Clear cached user data when switching to a non-EVM account group to prevent stale positions/orders from the previous EVM account

I thought we had discussed how this was a bad idea, and that we should migrate the controller fully to core instead? I'm not following what the plan is here. |

## **Description** Defensive hardening for edge cases in `PerpsController` surfaced by static analysis on Core PR [#7941](MetaMask/core#7941). None of these bugs are currently triggerable in production — the app works correctly today — but all represent latent issues that could bite under future changes or unusual network conditions. ### What changed **1. `toggleTestnet()` — false success on silent init failure** `performInitialization()` catches errors internally and sets `InitializationState.Failed` instead of throwing. `toggleTestnet()` was not checking for this, so it could return `{ success: true }` even when the network switch failed. This patch: - Adds the same `InitializationState.Failed` check after `await this.init()` - Rolls back `isTestnet` to its previous value on failure **2. `depositWithConfirmation()` — never-resolving promise when `placeOrder=true`** The `placeOrder` path created `new Promise(() => {})` — a promise that can never be GC'd and would hang any consumer who awaits it. Replaced with `Promise.resolve(transactionMeta.id)` for proper fire-and-forget semantics. **3. `depositWithConfirmation()` — failed deposits remain permanently pending** `depositWithConfirmation` adds a pending entry to `state.depositRequests` before validating `networkClientId`. If the validation throws, the deposit request stays `status: 'pending'` forever. This patch marks the deposit request as `failed` in the outer catch when a pre-submission error occurs. **4. Feature flag listener lost after disconnect** `disconnect()` unsubscribed `RemoteFeatureFlagController:stateChange` but no reconnect path re-subscribed. After disconnect → reconnect, geo-blocking and HIP-3 flag changes stopped propagating. The feature-flag subscription is a controller-lifetime concern (not session-lifetime), so we removed the unsubscribe from `disconnect()` entirely — the subscription now lives for the full controller lifecycle. **5. `depositWithConfirmation()` — deposit+order request stays pending forever** When `placeOrder=true`, the `if (!placeOrder)` guard skips the `.then()/.catch()` lifecycle block that transitions the deposit request to `completed`/`failed`. No other handler exists for this path. Added an `else if` branch that attaches lifecycle tracking to `addResult.result` (the real transaction promise) for the deposit+order flow. **6. Non-EVM account switch leaves stale cache** The account-change handler only cleared cached user data when `currentAddress` is truthy. Switching to an account group with no EVM account (e.g., Bitcoin-only) skipped cache clearing, leaving stale positions/orders visible. Restructured the condition so cache is always cleared when the account group changes, with preload guarded separately behind `if (currentAddress)`. ## **Changelog** CHANGELOG entry: null ## **Related issues** Fixes: bugbot findings from Core PR [#7941](MetaMask/core#7941) ## **Manual testing steps** These are defensive fixes for edge cases not reachable through normal UI flows. Verification is via unit tests. ```gherkin Feature: Perps network toggle resilience Scenario: toggleTestnet reports accurate status when init fails silently Given user is on mainnet with perps initialized When user toggles to testnet and initialization fails internally Then toggleTestnet returns { success: false } And isTestnet is rolled back to its previous value Feature: Perps deposit promise contract Scenario: depositWithConfirmation result promise resolves when placeOrder is true Given user initiates a deposit with placeOrder=true When the transaction is submitted Then the result promise resolves with the transaction ID Feature: Perps deposit request lifecycle Scenario: deposit request is marked failed on pre-submission error Given user initiates a deposit and the deposit request is added as pending When the networkClientId lookup fails Then the deposit request status is updated to 'failed' Scenario: deposit+order request transitions from pending Given user initiates a deposit with placeOrder=true When the transaction completes or fails Then the deposit request status is updated to 'completed' or 'failed' Feature: Feature flag subscription resilience Scenario: geo-blocking flags propagate after disconnect/reconnect Given perps controller is initialized with feature flag subscription When disconnect() is called and controller reconnects Then feature flag changes still propagate correctly Feature: Account switch cache clearing Scenario: switching to non-EVM account clears stale perps cache Given user has cached perps data from an EVM account When user switches to a Bitcoin-only account group Then cached positions, orders, and account state are cleared ``` ## **Screenshots/Recordings** N/A — no UI changes, logic-only hardening. ## **Pre-merge author checklist** - [x] I've followed [MetaMask Contributor Docs](https://github.com/MetaMask/contributor-docs) and [MetaMask Mobile Coding Standards](https://github.com/MetaMask/metamask-mobile/blob/main/.github/guidelines/CODING_GUIDELINES.md). - [x] I've completed the PR template to the best of my ability - [x] I've included tests if applicable - [x] I've documented my code using [JSDoc](https://jsdoc.app/) format if applicable - [ ] I've applied the right labels on the PR (see [labeling guidelines](https://github.com/MetaMask/metamask-mobile/blob/main/.github/guidelines/LABELING_GUIDELINES.md)).

Explanation
Syncs the full
PerpsControllerimplementation from Mobile into Core for npm publishing as@metamask/perps-controller.This builds on #7654 (initial package scaffolding) by adding the complete controller implementation: 59 source files covering the controller, providers (HyperLiquid, MYX), services, types, and utilities. Notably, Core's strict ESLint rules were adopted directly on the perps code in Mobile via metamask-mobile#26064 — this was initially thought to be impossible (one of the original blockers in the ADR-42 debate), but the result is a clean 1:1 file sync: source files are copied verbatim with zero modifications and no linting suppression needed.
Approach: Mobile remains the source of truth for active perps development. Core acts as the publishing vehicle — receiving synced source files and publishing them to npm via Core's existing release infrastructure. This is a pragmatic interim approach (~2 months) that avoids cross-repo DX friction while the controller and UI are being iterated on together rapidly. See `PERPS_CONTROLLER_CONTEXT.md` for full background on the ADR-42 debate and why this approach was chosen.
Key components added:
CI / Testing: The real unit tests live in Mobile alongside the source of truth. A minimal placeholder test (`tests/placeholder.test.ts`) is included to satisfy Core's CI requirement that every package has at least one test file. It lives in `tests/` (outside `src/`) so the Mobile sync script (`rsync --delete` on `src/`) does not remove it. Coverage collection is scoped to the placeholder file only, preventing 0% coverage failures on the synced source. Tests will be migrated when development moves fully to Core.

Note
High Risk
Large addition of trading- and transaction-related controller logic plus new dependencies and messenger/transaction-controller integration; failures could affect order/deposit/withdraw flows and background preloading behavior.
Overview
Syncs the full
@metamask/perps-controllerimplementation into Core for npm publishing, replacing the previous scaffolding/empty controller with a completePerpsControllerthat manages state, initialization/retry, provider switching (HyperLiquid/MYX/aggregated), deposits/withdrawals (viaTransactionController), eligibility gating, background market/user-data preloading, and messenger-exposed method handlers.Adds the multi-provider realtime aggregation layer (
SubscriptionMultiplexer) plus portable constants/types (e.g., chart config) and introduces many new package dependencies required for providers and inter-controller integrations. Testing/CI setup is adjusted by removing the old unit test and scoping Jest coverage to a placeholder test file only, and the changelog is updated to reflect the full feature set and generated messenger action types.Written by Cursor Bugbot for commit f683bcd.
