Querying Balances

Import the common package:

import (
    "github.com/PhoenixGlobal/Phoenix-Chain-SDK/libs/common"
)

Query the balance of an account at the latest block:

account := common.HexToAddress("0xF35F4545fa03416C4ABb9FC9c743EDa6e35c5592")
latestBalance, err := client.BalanceAt(context.Background(), account, nil)
if err != nil {
    log.Fatal(err)
}
fmt.Println(latestBalance)

You can also query the balance of an account at a certain block height:

blockNumber := big.NewInt(21879393)
account := common.HexToAddress("0xF35F4545fa03416C4ABb9FC9c743EDa6e35c5592")
balance, err := client.BalanceAt(context.Background(), account, blockNumber)
if err != nil {
    log.Fatal(err)
}
fmt.Println(balance)
