# eth\_getTransactionReceipt - Bittensor

Returns the receipt of a confirmed EVM transaction — gas used, logs emitted, status (1 = success, 0 = revert), and contract address if the transaction created a contract.

{% hint style="info" %}
**Subtensor EVM JSON-RPC method.** Call against a GetBlock endpoint configured for the **EVM interface** (not the Substrate interface). Subtensor EVM uses chain ID **945** (`0x3b1`). Standard Ethereum tooling — ethers.js, viem, Hardhat, Foundry, MetaMask — works unmodified.
{% endhint %}

## Parameters

| Parameter | Type            | Required | Description      |
| --------- | --------------- | -------- | ---------------- |
| txHash    | DATA (32 bytes) | Yes      | Transaction hash |
