System ArchiveMetamask Extension P0 Investigate And Cap Multichain Account Creation/Syncing Span FanOut Symptom Users experience excessive account creation and syncing issues with Metamask, resulting in a significant increase in span fanout, leading to performance degradation and potential crashes. Technical Root Cause The error occurs due to an uncontrolled growth of multichain accounts, causing the Metamask extension to overload and struggle to manage the numerous account syncing requests, ultimately leading to a fanout effect. Manual Overrides To mitigate the issue, apply the following manual overrides: Limit the number of multichain accounts created within a specific timeframe Implement a rate limiter to restrict excessive syncing requests Utilize the following JSON configuration to cap account creation: json { "accountCreationLimit": 10, "syncRequestLimit": 5, "timeframe": "1h" } Consider utilizing an external console for more finegrained control over the configuration. Prerequisites Metamask extension installed and configured Basic understanding of Ethereum ecosystem and multichain accounts Familiarity with JSON configuration files and rate limiting concepts
