const balanceParams: BalancesDto =
      {
          // if no chainId is supplied, SDK will automatically pick active one that
         //  is being supplied for initialization

        chainId: ChainId.MAINNET, // chainId of your choice
        eoaAddress: smartAccount.address,
        // If empty string you receive balances of all tokens watched by Indexer
        // you can only whitelist token addresses that are listed in token respository

const balFromSdk = await smartAccount.getAlltokenBalances(balanceParams);
console.info("balFromSdk ", balFromSdk);

const usdBalFromSdk = await smartAccount.getTotalBalanceInUsd(balanceParams);
console.info("usdBalFromSdk ", usdBalFromSdk)
