// yarn add @tatumio/tatum

import { TatumSDK, Cronos, Network } from '@tatumio/tatum'
const tatum = await TatumSDK.init<Cronos>({network: Network.CRONOS})

const tx = await tatum.rpc.getTransactionByBlockHashAndIndex('0x6565fd5921f93655e77d8cfeab8aa6caaf7155aeae24e91cdca33eedc66e6c5a', 0)

eth_getTransactionByBlockHashAndIndex is an 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.

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


The eth_getTransactionByBlockHashAndIndex method accepts two parameters:

  1. blockHash (required): The hash of the block containing the transaction.

    • Example: "0x6565fd5921f93655e77d8cfeab8aa6caaf7155aeae24e91cdca33eedc66e6c5a"

  2. transactionIndex (required): The index of the transaction within the specified block. The index is a hexadecimal value.

    • Example: "0x0"

Return Object

The method returns a JSON object containing the following fields:

  1. hash: The transaction hash as a 32-byte hex string.

  2. nonce: The number of transactions made by the sender prior to this one.

  3. blockHash: The hash of the block in which this transaction is included.

  4. blockNumber: The block number in which this transaction is included.

  5. transactionIndex: The index of the transaction within the block.

  6. from: The address of the sender.

  7. to: The address of the recipient. null if the transaction is a contract creation transaction.

  8. value: The value transferred in wei.
