Description

1. What is the reason for the change?

As explained in #5321, users have to be able to choose if they want to query for their accounts balance in batch or one account at a time.

2. What is the improvement/solution?

• add a new setting section with a switch in Security & privacy settings to select between batch balance request or single selected account balance request. Use the provided description.
• use batch mode by default (default value to true, switch selected)
• save setting value in state and update UI from state
• add translation strings
• add MetaMetricsEvents
  • example events sent:

     INFO  TRACK event saved {"anonymousId": "0x0000000000000000", "event": "Batch account balance requests", "properties": {"batch": "ON"}, "type": "track", "userId": "0x38335acdbca7be5d1a7b10290e37a086d69705aa49f5a03dfd1e3db8ebc91ca8"}
     INFO  TRACK event saved {"anonymousId": "0x0000000000000000", "event": "Batch account balance requests", "properties": {"batch": "OFF"}, "type": "track", "userId": "0x38335acdbca7be5d1a7b10290e37a086d69705aa49f5a03dfd1e3db8ebc91ca8"}
    

• patch controllers to query only the selected account balance or batch query all accounts according to setting in state
• add unit test

@Fatxx sending this back your way:

1. Translations are missing.

2. I cannot see analytic events:

• Locally when I enable and disable “batch account balance requests”
• In a preproduction version of the app: I had an iOS version of the QA app > I went ahead and toggled “batch account balance requests” to off, but when I searched mix panel the analytics did not appear.

What wasn't tested:
upgrading the app from a previous version to a version containing this PR. Can we kick off a release build for this branch?
