Fetching Transaction Receipt

The getTransactionReceipt method allows you to retrieve the receipt of a specific transaction on the OP_NET network. This receipt includes detailed information about the transaction's execution, such as logs, events, and proofs validating the receipt.

Method

getTransactionReceipt(txHash: string): Promise<TransactionReceipt>;

• Parameters:

  • txHash: string: The hash of the transaction to fetch the receipt for.

• Returns:

  • Promise<TransactionReceipt>: A transaction receipt object containing detailed information.

Object Definitions

TransactionReceipt Object

Property	Type	Description
receipt	Buffer	The raw receipt data (optional).
receiptProofs	string[]	Proofs validating the transaction's receipt.
events	ContractEvents	Logs emitted by the transaction, typically contract events.
revert	Buffer	Revert reason for failed transactions (optional).

---

Example Usage

const txHash = "8bdb1b21a...";
const receipt = await provider.getTransactionReceipt(txHash);

console.log("Transaction Receipt:", receipt);
console.log("Receipt Proofs:", receipt.receiptProofs);
console.log("Events:", receipt.events);
if (receipt.revert) {
  console.log("Revert Reason:", receipt.revert.toString("utf-8"));
}

---

Best Practices

• Check the revert field to identify if the transaction failed.
• Use the events property to analyze emitted logs, which are essential when interacting with smart contracts.
• The receiptProofs provide cryptographic validation for the receipt, ensuring its integrity.
