Note

Fetch fiat rates only for non-native tokens in the dapp-swap comparison hook to correctly handle native assets.

• Hooks:
  • Update ui/pages/confirmations/hooks/transactions/dapp-swap-comparison/useDappSwapUSDValues.ts to filter out native addresses from tokenAddresses before calling fetchTokenExchangeRates('usd', ...), avoiding fiat rate requests for native tokens.
