# eth\_getTransactionByHash - ARC

Example code for the eth\_getTransactionByHash JSON-RPC method. Complete guide on how to use eth\_getTransactionByHash JSON-RPC in GetBlock Web3 documentation.

This method returns transaction details by transaction hash. Useful for inspecting any transaction once you have its hash from a broadcast or a block listing. Note that all USDC amounts in the response (`value`, `gasPrice`, `maxFeePerGas`) are in USDC base units, not 18-decimal wei.

## Parameters

| Parameter       | Type   | Required | Description                     |
| --------------- | ------ | -------- | ------------------------------- |
| transactionHash | string | Yes      | 32-byte hash of the transaction |
