eth_getTransactionByBlockHashAndIndex

The eth_getTransactionByBlockHashAndIndex method returns information about a transaction by block hash and transaction index position. This method allows you to retrieve a specific transaction from a block when you know the exact block hash and the transaction's position within that block.

This method is particularly useful for sequential transaction processing, iterating through all transactions in a specific block, building block explorers that display transactions in order, and analyzing transaction patterns within blocks. Unlike eth_getTransactionByHash which requires knowing the transaction hash, this method lets you discover transactions by their position. The block hash parameter ensures you're querying a specific block even in the case of chain reorganizations, making it more reliable than using block numbers for critical applications.

Parameters

parameter	type	description
blockHash	string (required)	Hash of the block (32 bytes)
transactionIndex	string (required)	Transaction index position in hex

Return Object

The method returns a transaction object, or null if no transaction exists at the specified index:

field	type	description
blockHash	string	Hash of the block containing this transaction (32 bytes)
blockNumber	string	Block number containing this transaction (hex)
from	string	Address of the sender (20 bytes)
to	string	Address of the receiver (20 bytes), null for contract creation transactions
gas	string	Gas limit provided by the sender (hex)
gasPrice	string	Gas price provided by the sender in wei (hex), for legacy and EIP-2930 transactions
maxFeePerGas	string	Maximum total fee per gas the sender is willing to pay (hex, in wei), for EIP-1559 transactions
maxPriorityFeePerGas	string	Maximum priority fee per gas (tip) the sender is willing to pay (hex, in wei), for EIP-1559 transactions
hash	string	Hash of the transaction (32 bytes)
input	string	The data sent along with the transaction (hex-encoded). Contains the function signature and encoded parameters for contract calls
nonce	string	Number of transactions sent by the sender prior to this one (hex)
value	string	Value transferred in wei (hex)
transactionIndex	string	Integer of the transaction's index position in the block (hex)
type	string	Transaction type: 0x0 for legacy, 0x1 for EIP-2930, 0x2 for EIP-1559
chainId	string	Chain ID of the transaction (hex)
v	string	ECDSA recovery id
r	string	ECDSA signature r
