How to use it

// yarn add @tatumio/tatum

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

const tx = await tatum.rpc.getTransactionReceipt('0xa3fd3d2b01ee234899b487fb1480b7e14142dde55f07b7a079b9fdcf04733220')

await tatum.destroy() // Destroy Tatum SDK - needed for stopping background jobs


klay_getTransactionReceipt is an JSON-RPC method that retrieves the transaction receipt of a given transaction hash. This method is particularly useful when you need to obtain detailed information about a transaction's execution, such as its status (success or failure), gas usage, and logs (events). Common use cases include checking the status of a transaction after it has been mined or inspecting the events emitted by a smart contract during a specific transaction.


This method requires a single parameter:

  • transactionHash: The hash of the transaction for which you want to obtain the receipt.

    • Example: "0x97d83656ca05890100149be18d0c2a2f94e5337e5e6a643ea78794cd418cdbc7"

Return Object

The method returns an object containing the following fields:

  • transactionHash: The hash of the transaction.

  • transactionIndex: The transaction's index position in the block.

  • blockHash: The hash of the block where this transaction was mined.

  • blockNumber: The block number where this transaction was mined.

  • from: The address of the sender.

  • to: The address of the receiver. null when it's a contract creation transaction.

  • cumulativeGasUsed: The total amount of gas used when this transaction was executed in the block.

  • gasUsed: The amount of gas used by this specific transaction alone.

  • contractAddress: The address of the contract created, if the transaction was a contract creation. Otherwise, null.

  • logs: An array of log objects, which were emitted during the transaction.

  • logsBloom: A 256-byte bloom filter, which is a compressed representation of the logs emitted during the transaction.

  • status: The status of the transaction's execution. "0x1" indicates success, while "0x0" indicates failure.
