eth_getTransactionByBlockHashAndIndex

Overview

The eth_getTransactionByBlockHashAndIndex is an Ethereum JSON-RPC method that allows you to fetch the transaction details based on the block hash and the index of the transaction within that block. This method can be useful when you want to retrieve transaction details for a specific transaction without knowing its transaction hash.

Usecase

Use cases for this method may include:

Inspecting transaction details for debugging purposes
Gathering data for transaction analysis
Fetching transaction information for specific blocks in a block explorer application

Parameters

The eth_getTransactionByBlockHashAndIndex method accepts two parameters:

blockHash (required): The hash of the block containing the transaction.
- Example: "0x742d35Cc6634C0532925a3b844Bc454e4438f44e"
transactionIndex: (required): The index of the transaction within the specified block. The index is a hexadecimal value.
- Example: "0x1"

Returns

The method returns a JSON object containing the following fields:

Name	Description
hash	The transaction hash as a 32-byte hex string.
nonce	The number of transactions made by the sender prior to this one.
blockHash	The hash of the block in which this transaction is included.
blockNumber	The block number in which this transaction is included.
transactionIndex	The index of the transaction within the block.
from	The address of the sender.
to	The address of the recipient. `null` if the transaction is a contract creation transaction.
value	The value transferred in wei.
