# eth\_getTransactionByHash - Optimism

This method retrieves comprehensive transaction data, including the sender, recipient, value, gas parameters, input data, and block information. It's one of the most commonly used methods for tracking transaction status and retrieving transaction details. The method returns null if the transaction is not found. On Optimism, the transaction object may include additional L2-specific fields.

### Parameters

### Use Case

The eth\_getTransactionByHash method is commonly used for:

* **Transaction tracking**
* **Payment verification**
* **Debugging transactions**
* **Transaction history display**

#### Error handling

| Status Code | Error Message    | Cause                                         |
| ----------- | ---------------- | --------------------------------------------- |
| 404         | Not Found        | Missing or invalid ACCESS\_TOKEN.             |
| -32602      | Invalid argument | <ul><li>Transaction hash is invalid</li></ul> |

#### Integration with Web3

The `eth_getTransactionByHash` method helps developers to:

* Build trustless frontends that check transaction status directly
* Track pending, failed, or confirmed transactions in real time
* Support dashboards, DeFi interfaces, wallets, and explorers
* Read transaction calldata for analytics and debugging
* Improve UX by notifying users instantly when their transaction is included
* Verify transaction ordering for MEV, priority fees, and gas bidding strategies
