Description

Performance Comparison: Per-Chain Token Cache Storage

This PR implements per-chain file storage for tokensChainsCache in TokenListController, replacing the single-file approach. Each chain's token list is now stored in a separate file via StorageService, reducing write amplification during incremental updates.

📊 Summary

Category	This PR	Main Branch	Improvement
Cold restart (getAllPersistedState)	216.20ms	374.30ms	42% faster
Cold restart (cache load)	~310ms (parallel)	Included in state	-----
Onboarding - Token cache	4.40MB (StorageService)	4.40MB (in state)	Stored separately
Onboarding - Background saves	~23MB each	~28MB each	~5MB less per save
Onboarding - Token cache in saves	❌ No	✅ Yes	Eliminated
Add Monad	39KB (new chain only)	~4.4MB (full cache rewritten)	Only new chain
Add Avalanche	157KB (new chain only)	~4.6MB (full cache rewritten)	Only new chain
Background saves (idle)	~23MB	~28MB	~18% smaller
TokenListController in state	0.04KB	4,601KB	Cache moved out

Key Results:

Adding a single chain on main branch triggers a state save that rewrites all TokenListController cache (~4.6MB) plus all other controllers (~23MB) = ~28MB total.
This PR writes ONLY the new chain (e.g., 39KB for Monad) to StorageService. The full token cache is NOT rewritten.
Background saves are ~5MB smaller (~23MB vs ~28MB) because the token cache is stored separately.

🧪 Test Scenarios

Scenario 1: Cold Restart (Existing User)

Setup: Extension with 10 networks cached (8 popular + Monad + Avalanche), then browser restart.

Total cache size: ~4.60MB across 10 chains

Main Branch

Cold restart with 10 networks cached (8 popular + Monad + Avalanche):

[ControllerStorage PERF] getAllPersistedState started
[ControllerStorage PERF] getAllPersistedState complete - 374.30ms
[ControllerStorage PERF] TokenListController read - 4601.13KB - 374.30ms

Comparison

Metric	This PR	Main Branch	Improvement
getAllPersistedState	216.20ms	374.30ms	42% faster
TokenListController in state	0.04KB	4,601KB	Moved to StorageService
StorageService cache load	~163ms (10 chains parallel)	N/A	Separate loading
Total chains	10	10	Same
Total state size	~23MB	~28MB	~18% smaller

Key insight: The main state loads 158ms faster on this PR because it's ~5MB smaller. The token cache is loaded separately via StorageService in parallel during controller initialization.

Scenario 2: Fresh Onboarding

Setup: Fresh wallet creation, enable all popular networks, wait for token lists to fetch.

Summary:

Total data written: ~4.40MB (8 individual writes)
Number of writes: 8 (one per chain)
Total write time: ~509ms (sum of individual writes)

Main Branch

Initial state (fresh install):

[ControllerStorage PERF] getAllPersistedState complete - 14.60ms
[ControllerStorage PERF] set() - TokenListController size: 0.06KB
[ControllerStorage PERF] set() complete - 9952.04KB - 129.10ms

After clicking "All Popular Networks":

[ControllerStorage PERF] set() - TokenListController size: 4405.07KB
[ControllerStorage PERF] set() complete - 27830.24KB - 526.70ms

Summary:

TokenListController size: 4,405KB (~4.4MB) - cached in controller state
Total state written: 27,830KB (~27.2MB) - entire MetaMask state
Write time: 526.70ms

Comparison

Metric	This PR	Main Branch	Difference
Token cache data	4.40MB	4.40MB	Same amount
Token cache location	StorageService (separate)	Main state	Separated
Background save size	~23MB	~28MB	~5MB smaller
Token cache in every save	❌ No	✅ Yes	Eliminated

Key insight: Both branches have continuous background saves. On main branch, every save includes the ~4.4MB token cache. On this PR, the token cache is stored separately via StorageService, making each background save ~5MB smaller.

Scenario 3: Add New Chain

Setup: Existing wallet with cached networks, add a new network.

🔧 How Performance Was Measured

Performance logging was added to:

BrowserStorageAdapter (app/scripts/lib/stores/browser-storage-adapter.ts)
- Logs for getItem, setItem, getAllKeys operations
- Measures read time, stringify time, write time, and data size
ExtensionStore (app/scripts/lib/stores/extension-store.ts)
- Logs for getAllPersistedState and controller state writes
- Measures TokenListController-specific read/write performance

To enable logging, set PERF_LOGGING_ENABLED = true in both files.

📝 Logging Code Reference (Main Branch)

The following code was added to extension-store.ts on main branch to capture performance metrics:

Helper Functions (add at top of file after imports)

// ============ PERF LOGGING (for testing) ============
const PERF_LOGGING_ENABLED = true;

function getSizeKB(obj: unknown): string {
  try {
    const str = JSON.stringify(obj);
    return (str.length / 1024).toFixed(2);
  } catch {
    return 'N/A';
  }
}

function logControllerReadPerf(
  controllerName: string,
  data: unknown,
  timeMs: number,
): void {
  if (!PERF_LOGGING_ENABLED) {
    return;
  }
  const sizeKB = getSizeKB(data);
  console.warn(
    `[ControllerStorage PERF] ${controllerName} read - ${sizeKB}KB - ${timeMs.toFixed(2)}ms`,
  );
}

function logControllerWritePerf(
  controllerName: string,
  data: unknown,
  timeMs: number,
): void {
  if (!PERF_LOGGING_ENABLED) {
    return;
  }
  const sizeKB = getSizeKB(data);
  console.warn(
    `[ControllerStorage PERF] ${controllerName} write - ${sizeKB}KB - ${timeMs.toFixed(2)}ms`,
  );
}
// ============ END PERF LOGGING ============

In `get()` method - Add at start of method:

const perfStart = performance.now();
if (PERF_LOGGING_ENABLED) {
  console.warn('[ControllerStorage PERF] getAllPersistedState started');
}

In `get()` method - Add after data is loaded:

// PERF: Log overall time and TokenListController size
if (PERF_LOGGING_ENABLED) {
  const elapsed = performance.now() - perfStart;
  console.warn(
    `[ControllerStorage PERF] getAllPersistedState complete - ${elapsed.toFixed(2)}ms`,
  );
  // Log TokenListController state size specifically
  if (data.TokenListController) {
    logControllerReadPerf(
      'TokenListController',
      data.TokenListController,
      elapsed,
    );
  }
}

In `set()` method - Add logging:

const perfStart = performance.now();

// PERF: Log TokenListController size before write
if (
  PERF_LOGGING_ENABLED &&
  isObject(data) &&
  hasProperty(data, 'TokenListController')
) {
  const tlcSize = getSizeKB(data.TokenListController);
  console.warn(
    `[ControllerStorage PERF] set() - TokenListController size: ${tlcSize}KB`,
  );
}

// ... existing set logic ...

// PERF: Log total write time (add after await local.set())
if (PERF_LOGGING_ENABLED) {
  const elapsed = performance.now() - perfStart;
  const totalSize = getSizeKB({ data, meta });
  console.warn(
    `[ControllerStorage PERF] set() complete - ${totalSize}KB - ${elapsed.toFixed(2)}ms`,
  );
}

Expected Log Output

Cold Restart:

[ControllerStorage PERF] getAllPersistedState started
[ControllerStorage PERF] getAllPersistedState complete - 374.30ms
[ControllerStorage PERF] TokenListController read - 4601.13KB - 374.30ms

Write (adding chain or background save):

[ControllerStorage PERF] set() - TokenListController size: 4601.13KB
[ControllerStorage PERF] set() complete - 28036.55KB - 559.30ms

💡 Key Takeaways

Write amplification eliminated: Adding a single chain now writes only that chain's data (~30-200KB) instead of the entire cache (~4MB)
Faster incremental updates: Per-chain writes are significantly faster than full cache rewrites
Cold restart trade-off: Parallel file reads + getAllKeys adds some overhead vs single file read, but the difference is minimal
Onboarding improvement: Total data written during onboarding is reduced by avoiding cumulative rewrites

✅ PR Branch: Background Writes No Longer Include Token Cache

On this PR branch, background writes show:

[ControllerStorage PERF] set() - TokenListController size: 0.04KB    ← TINY! No cache!
[ControllerStorage PERF] set() complete - 23425.30KB - 481.60ms      ← ~23MB (not 28MB)

Key proof: TokenListController is only 0.04KB in the main state because the ~4.4MB token cache is stored separately in StorageService.

⚠️ Main Branch: Continuous Background Write Amplification

During testing on main branch, we observed that the entire 27.8MB state is being rewritten repeatedly even when the user is idle:

[ControllerStorage PERF] set() - TokenListController size: 4444.22KB
[ControllerStorage PERF] set() complete - 27877.62KB - 632.30ms
[ControllerStorage PERF] set() - TokenListController size: 4444.22KB
[ControllerStorage PERF] set() complete - 27877.62KB - 456.40ms
[ControllerStorage PERF] set() - TokenListController size: 4444.22KB
[ControllerStorage PERF] set() complete - 27877.62KB - 606.40ms
[ControllerStorage PERF] set() - TokenListController size: 4444.22KB
[ControllerStorage PERF] set() complete - 27877.59KB - 625.10ms
[ControllerStorage PERF] set() - TokenListController size: 4444.22KB
[ControllerStorage PERF] set() complete - 27877.59KB - 597.90ms

Why This Happens

MetaMask has background processes that trigger state saves:

Token balance polling
Price updates
Network status checks
Account sync
DeFi positions updates
etc.

Each time ANY controller state changes, the entire state (~27.8MB) is serialized and written to storage, including the 4.4MB TokenListController cache that hasn't changed.

Impact Comparison

Metric	This PR	Main Branch
State size per write	~23MB	~28MB
TokenListController in state	0.04KB	4,601KB
Token cache included in saves	❌ No	✅ Yes (every save)
Write time	~480ms	~550ms

How This PR Helps

By moving tokensChainsCache to StorageService:

Background saves are ~18% smaller (~23MB instead of ~28MB)
Token cache only written when it actually changes (new chain added or cache refresh)
Reduced disk I/O - ~5MB less data serialized and written on every background save
Better SSD/storage health - less unnecessary write cycles

Changelog

CHANGELOG entry: No user facing changes; this only updates the storage location for tokenListController.

Note

Medium Risk
Medium risk because it changes how TokenListController persists cached token lists and adds a state migration writing to browser.storage.local, which could impact startup/migration behavior if keys or storage operations fail.

Overview
Moves TokenListController token list caching to StorageService. The controller messenger now allows StorageService:* actions and TokenListControllerInit fires controller.initialize() on startup to load cached lists from storage (logging errors but not failing init).

Adds migration #190 to preserve existing caches. Migration 190 copies tokensChainsCache entries into per-chain storageService:TokenListController:tokensChainsCache:{chainId} keys without overwriting existing entries, then clears the in-state cache and bumps fixtures/snapshots to version 190.

Updates tests and deps for the new storage behavior. Jest mocks for webextension-polyfill are made async/shared across imports, e2e state persistence ignores StorageService-prefixed keys, and @metamask/assets-controllers is bumped to ^98.0.0.
