eth_getTransactionReceipt

Returns the receipt of a transaction by transaction hash.

The receipt is not available for pending transactions.

Parameters

• id (integer; required): a request ID (example: 1).

• jsonrpc (string; required): a JSON RPC spec used (example: 2.0).

• method (string; required): a method used for the request.

• params (array; required):

  1. <string> (data, 32 bytes): a hash of the transaction.

Returns

• object: a transaction receipt object, or null when no receipt was found:

  • transactionHash (string; data, 32 bytes): a hash of the transaction.

  • transactionIndex (string; quantity): the transactions index position in the block.

  • blockHash (string; data, 32 bytes): a hash of the block containing the transaction.

  • blockNumber (string; quantity): a number of the block containing the transaction.

  • from (string; data, 20 bytes): an address of the sender.

  • to (string; data, 20 bytes): an address of the receiver; null when it's a contract creation transaction.

  • cumulativeGasUsed (string; quantity): the total amount of gas used when this transaction was executed in the block.

  • effectiveGasPrice (string; quantity): the sum of the base fee and tip paid per unit of gas.

  • gasUsed (string; quantity): the amount of gas used by this specific transaction alone.

  • contractAddress (string; data, 20 bytes): the contract address created, if the transaction was a contract creation, otherwise null.

  • logs (array): an array of log objects, which this transaction generated.

  • logsBloom (string; data, 256 bytes): a bloom filter for light clients to quickly retrieve related logs.

  • type (string; data): the transaction type, 0x00 for legacy transactions, 0x01 for access list types, 0x02 for dynamic fees. It also returns either of the following:

    • root (string; data, 32 bytes): a post-transaction stateroot (pre Byzantium).
    • status (string; quantity): either 1 (success) or 0 (failure).
