import { ChainId } from '@biconomy/core-types'
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 respostory
// specified above ^
tokenAddresses: [],
const balFromSdk = await smartAccount.getAlltokenBalances(balanceParams);;
const usdBalFromSdk = await smartAccount.getTotalBalanceInUsd(balanceParams);;
