App Performance Start-Up: Transaction Element Optimizations

[sethkfman]

What is this about?

As a user, I want the MetaMask app to start up as fast as possible. During the application start-up it was identified that aspects of the TransactionElement/utils.js is adding about 3 seconds to the app startup on Android devices.

Scenario

Design

No response

Technical Details

• import decodeTransaction in TransactionNotification, TransactionElement, and TransactionDetails
  • Commenting out the entire TransactionElement/utils.js resolves the slow down
  • @tomás Santos performed a quick test on only removing this, which seemed to reduce start up time by ~3 seconds

Threat Modeling Framework

No response

Acceptance Criteria

• Root cause the impact to start up time and shift the activity to after the user has logged into the application.
• Track app start time improvement
