--data-raw {
  "jsonrpc": "2.0",
  "method": "eth_getBlockTransactionCountByHash",
  "params": ["0x94c626286c237e187454ddd993adc534f0ce3468aaec134a39fbd52185cc3a5f"],
  "id": "getblock.io"
}

Response

Below is a sample JSON response returned by eth_getBlockTransactionCountByHash upon a successful call:

{
  "jsonrpc": "2.0",
  "id": "getblock.io",
  "result": "0x5e"
}

Body Parameters

Here is the list of body parameters for the eth_getBlockTransactionCountByHash method:

1. jsonrpc: Specifies the version of the JSON-RPC protocol. In this case, it is "2.0".

2. id: A unique identifier for the request. In this example, it is "getblock.io".

3. result: The hexadecimal representation of the number of transactions in the block, which is "0x5e" in this response. This indicates the block contains 94 transactions.

Use Cases

Here are some use-cases for the eth_getBlockTransactionCountByHash method:

1. Transaction Analysis and Statistics: Developers and analysts can use the eth_getBlockTransactionCountByHash method to determine the number of transactions included in a specific block. This can be useful for generating statistics about network activity, such as average transactions per block, or for analyzing the activity levels during specific periods or events on the Ethereum blockchain.

2. Blockchain Monitoring and Alerts: By regularly querying the transaction count of new blocks using eth_getBlockTransactionCountByHash, monitoring systems can be set up to detect unusual spikes or drops in transaction activity. This can help in identifying potential network issues, attacks, or significant events that might require further investigation or immediate action.

3. Application Performance Optimization: For decentralized applications (dApps) that rely on blockchain data, knowing the transaction count of recent blocks can help optimize performance. For example, if a dApp needs to process all transactions in a block, knowing the transaction count in advance can help allocate the appropriate resources and manage load efficiently.

Code for eth_getBlockTransactionCountByHash

Python

import requests
import json
url = "https://go.getblock.io/<ACCESS-TOKEN>/"
headers = {
    "Content-Type": "application/json"
}
payload = {
  "jsonrpc": "2.0",
  "method": "eth_getBlockTransactionCountByHash",
  "params": ["0x94c626286c237e187454ddd993adc534f0ce3468aaec134a39fbd52185cc3a5f"],
  "id": "getblock.io"
}

response = requests.post(url, headers=headers, data=json.dumps(payload))

# Check the response and print the result
if response.status_code == 200:
    print("Result:", response.json().get("result"))
else:
    print("Error:", response.status_code, response.text)

JavaScript

const axios = require('axios');

const url = "https://go.getblock.io/<ACCESS-TOKEN>/";
const payload = {
  "jsonrpc": "2.0",
  "method": "eth_getBlockTransactionCountByHash",
  "params": ["0x94c626286c237e187454ddd993adc534f0ce3468aaec134a39fbd52185cc3a5f"],
  "id": "getblock.io"
};

axios.post(url, payload, {
  headers: { "Content-Type": "application/json" }
})
.then(response => {
  console.log("Result:", response.data.result);
})
.catch(error => {
  if (error.response) {
    console.error("Error:", error.response.status, error.response.data);
  } else {
    console.error("Request failed:", error.message);
  }
});

Common Errors

When using the eth_getBlockTransactionCountByHash JSON-RPC API BSC method, the following issues may occur:

• Invalid block hash: Ensure that the block hash provided is accurate and corresponds to an existing block on the BNB Smart Chain. Verify the hash format and its existence in the blockchain.

• Network connectivity issues: If the request fails to return a response, check your network connection and ensure that your node is properly synchronized with the BNB Smart Chain.

• Incorrect node configuration: Verify that your node is configured correctly to interact with the BSC network. Ensure that the node is running and connected to the correct network to process the request.

• API rate limits: Exceeding API rate limits can result in request failures. Consider implementing request throttling or upgrading your node service if necessary.

Using the eth_getBlockTransactionCountByHash method in Web3 applications offers the advantage of efficiently retrieving the number of transactions in a specific block via its hash. This functionality is essential for applications that need to analyze transaction volumes or validate block data on the BNB Smart Chain, enhancing the app's ability to interact with blockchain data seamlessly.
