How to Check TRON (Tron) Wallet Balance and Resources: TRX, USDT, Bandwidth, and Energy

This guide provides step-by-step methods to programmatically retrieve TRON wallet information, including TRX/USDT balances and remaining bandwidth/energy resources.

Key Features to Check in a TRON Wallet

1. TRX Balance: Native cryptocurrency of the TRON network
2. USDT (TRC20) Balance: Stablecoin transactions on TRON
3. Bandwidth: Network resource for regular transactions
4. Energy: Computational resource for smart contracts

Retrieving TRX and USDT Balances Online

private static Tuple<decimal, decimal> GetBalanceByAddressByOnline(string address) 
{
    var tuple = new Tuple<decimal, decimal>(0, 0);
    var responseString = HttpClientHelper.Get($"https://api.trongrid.io/v1/accounts/{address}");
    
    if (string.IsNullOrEmpty(responseString)) return tuple;
    
    var responseObject = JsonConvert.DeserializeObject<dynamic>(responseString);
    if (responseObject?.success != true || responseObject?.data == null) return tuple;
    
    var obj = responseObject.data[0];
    var trxBalance = obj?.balance != null ? (long)obj.balance / 1000000m : 0m;
    
    decimal usdtBalance = 0m;
    if (obj?.trc20 != null)
    {
        foreach (var token in obj.trc20)
        {
            var balance = token["TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t"];
            if (balance != null) usdtBalance = (long)balance / 1000000m;
        }
    }
    
    return new Tuple<decimal, decimal>(trxBalance, usdtBalance);
}

Checking Bandwidth and Energy Resources

private static Tuple<long, long> GetAccountResource(string address) 
{
    var requestObj = new { address = address, visible = true };
    var responseString = HttpClientHelper.Post(
        "https://api.trongrid.io/wallet/getaccountresource", 
        JsonConvert.SerializeObject(requestObj), 
        Encoding.UTF8
    );
    
    if (string.IsNullOrEmpty(responseString)) 
        return new Tuple<long, long>(0, 0);
        
    var responseObject = JsonConvert.DeserializeObject<dynamic>(responseString);
    
    long CalculateRemaining(long limit, long used) => 
        (limit != null ? Convert.ToInt64(limit) : 0) - 
        (used != null ? Convert.ToInt64(used) : 0);
    
    var bandwidth = CalculateRemaining(responseObject?.freeNetLimit, responseObject?.freeNetUsed) +
                  CalculateRemaining(responseObject?.NetLimit, responseObject?.NetUsed);
                  
    var energy = CalculateRemaining(responseObject?.EnergyLimit, responseObject?.EnergyUsed);
    
    return new Tuple<long, long>(bandwidth, energy);
}

Essential HttpClient Helper Class

public static class HttpClientHelper 
{
    public static string Get(string url, int timeout = 12000)
    {
        var request = (HttpWebRequest)WebRequest.Create(url);
        request.Timeout = timeout;
        request.Headers.Add("TRON-PRO-API-KEY", "your-api-key");
        
        using var response = (HttpWebResponse)request.GetResponse();
        using var stream = response.GetResponseStream();
        using var reader = new StreamReader(stream);
        return reader.ReadToEnd();
    }

    public static string Post(string url, string requestBody, Encoding encoding, int timeout = 12000)
    {
        var request = (HttpWebRequest)WebRequest.Create(url);
        request.Method = "POST";
        request.ContentType = "application/json";
        request.Timeout = timeout;
        request.Headers.Add("TRON-PRO-API-KEY", "your-api-key");
        
        var bytes = encoding.GetBytes(requestBody);
        using (var stream = request.GetRequestStream())
        {
            stream.Write(bytes, 0, bytes.Length);
        }
        
        using var response = (HttpWebResponse)request.GetResponse();
        using var responseStream = response.GetResponseStream();
        using var reader = new StreamReader(responseStream);
        return reader.ReadToEnd();
    }
}

FAQ: TRON Wallet Resources

Q: What's the difference between bandwidth and energy in TRON?
A: Bandwidth covers regular transactions while energy is required for smart contract executions.

Q: How often should I check my wallet balance programmatically?
A: For most applications, checking every 5-10 minutes is sufficient unless you need real-time updates.

Q: Can I use these methods for production applications?
A: Yes, but implement proper error handling and consider rate limits when calling the TRON Grid API.

Q: Why is my USDT balance showing zero when I know I have funds?
A: Ensure you're checking the correct TRC20 contract address (TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t).

Q: How can I optimize my bandwidth usage?
A: Consolidate transactions and stake TRX to earn additional bandwidth resources.

Q: What happens if I run out of energy?
A: Smart contract calls will fail - you'll need to either wait for energy to replenish or freeze TRX to get more.

Best Practices for TRON Developers

1. Always cache API responses when possible
2. Implement proper error handling for network issues
3. Consider using WebSocket connections for real-time updates
4. Monitor your API key usage to avoid rate limits
5. Keep your TRON Grid API key secure

Remember to test all wallet interactions thoroughly before deploying to production environments.
