# eth\_getTransactionByHash

## Summary

Returns a transaction by its hash.

The public MegaETH endpoint supports this method. The standard, node, and gateway layers below identify behavior that differs from a generic Ethereum endpoint.

## Parameters

**`transactionHash`** Hash32 **REQUIRED**

Target transaction hash.

## Result

`Transaction | null` — `null` when the transaction cannot be found.

* **`hash`** Hash32

  Transaction hash.
* **`type`** Quantity

  Transaction type identifier.
* **`from`** Address

  Sender.
* **`to`** Address | null

  Recipient; `null` for contract creation.
* **`value`** Quantity

  Transfer value in wei.
* **`nonce`** Quantity

  Sender nonce.
* **`gas`** Quantity

  Gas limit.
* **`input`** Data

  Calldata.
* **`blockHash`** Hash32 | null

  `null` for pending transactions.
* **`blockNumber`** Quantity | null

  `null` for pending transactions.
* **`transactionIndex`** Quantity | null

  `null` for pending transactions.

Additional fields vary by transaction type (`gasPrice`, `maxFeePerGas`, `accessList`, `chainId`, `v`, `r`, `s`, etc.).

## Comparison with Ethereum Standard JSON-RPC

### Ethereum Standard

The canonical Ethereum method uses the parameter and result contract documented above, including the stated `null`, `false`, or zero-value semantics where applicable.

### MegaETH Node Behavior

The node returns a transaction known to canonical storage or the live transaction view; an unknown hash produces `null`.

### MegaETH Public Gateway

The gateway caches included transactions for 30 minutes. A `null` result is not cached, so a later request can observe a transaction that has since become available.

## Errors

The `| Scope |` column distinguishes method failures from gateway policy errors.

| Code     | Scope            | Message             | When it happens                                             |
| -------- | ---------------- | ------------------- | ----------------------------------------------------------- |
| `-32602` | Request          | Invalid params      | Transaction hash is missing or malformed                    |
| `-32005` | Transport/policy | Rate limit exceeded | The caller exceeds the public gateway's simple read budget. |
| `-32099` | Transport/policy | Payload too large   | The request body exceeds the 128 KiB public endpoint limit. |

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.megaeth.com/developer-docs/rpc/reference/eth_gettransactionbyhash.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
