Note

Re-enables @typescript-eslint/no-misused-promises and @typescript-eslint/no-dynamic-delete, refactoring handlers and data structures (use Maps/immutable copies), adding explicit error handling, and adjusting timers/polling across UI, providers, and utilities.

• ESLint & Codebase-wide refactors:
  • Re-enable @typescript-eslint/no-misused-promises and @typescript-eslint/no-dynamic-delete in eslint.config.mjs.
  • Replace delete obj[key] patterns with immutable rest copies or Map APIs; migrate various caches/state to Map (perf timers, stake metadata cache, rates resolver map, filters, pending calls, etc.).
  • Convert async void UI handlers to non-async functions using promise chains with .catch(showError); tighten types (e.g., onPress?: () => Promise<void> where needed).
  • Wrap intervals/polling with safe tasks (makePeriodicTask) and ensure cleanup via .stop(); add centralized error reporting in periodic callbacks.
• UI/Scenes & Modals:
  • Update handlers in country selection, login, category/password modals, transfer/wallet selection, FIO scenes, wallet list components to avoid misused promises and use explicit error handling.
  • Minor signature/behavior tweaks (e.g., EarnOptionCard onPress, WalletList default onPress).
• Fiat providers & payment flows (banxa, kado, moonpay, paybis, revolut, simplex):
  • Harden webview/deeplink flows with error handling; refactor callbacks to non-async handlers; add polling via PeriodicTask; fix status handling.
• Utilities:
  • Refactor FIO address utils to avoid dynamic delete; adjust exchange rates queue to Map with safer iteration; improve app perf timer storage.
  • Misc reliability improvements (theme polling, WalletConnect unmount cleanup).
