Description

This is MVP v2 of token detection where we add support for custom networks. Supported networks: Mainnet, Binance, Polygon, and Avalanche.

Technical Details

• Enable Token Detection by default
• Update What's new screen to show carousel with Token Detection information
• Move Token Detection toggle to Advanced Settings screen
• Show search functionality on supported networks + Update banners
• Add tokens detected link below token list on Wallet screen
• Add tokens detected action sheet to display detected tokens + ability to ignore or add tokens
• Extend action sheet to have ability to drill into associated token lists
• Add token ignore modal that shows up the first time you uncheck/ignore a token
• Show token imported toast upon importing tokens from action sheet
• Will need to update the AssetsContractController to support switching between different networks
• Remove static token lists
• Update token detection logic to only control auto detection. This means that we will always be attempting to pull the dynamic token list regardless of toggle state.
• Add Token Added analytics event to importing tokens from action sheet
• Update Tokens Added analytics event to include source field

Acceptance Criteria

• Auto token detection should work on supported networks
• Dynamic list should populate token list on search (supported networks listed above in description)
• Should have ability to ignore and/or import detected tokens on supported networks
• Upgrading app should display Whats new modal with token detection information
• Analytics: Reusing existing analytics event Token Added but should also include source field
