# eth\_blockNumber - Monad

This method returns the number of the most recent block.

{% hint style="warning" %}
Due to Monad's \~400ms block time, block numbers increase much faster than on Ethereum (\~12 second blocks). Applications should account for this when implementing polling or confirmation tracking.
{% endhint %}

### Response

```json
{
    "jsonrpc": "2.0",
    "id": "getblock.io",
    "result": "0x1b4"
}
```

### Response Parameters

| Field  | Type   | Description                                     |
| ------ | ------ | ----------------------------------------------- |
| result | string | The current block number in hexadecimal format. |

### Use Case

The `eth_blockNumber` method is essential for:

* Monitoring blockchain height in real-time
* Synchronization status checks
* Building block explorers and dashboards
* Tracking transaction confirmations
* Implementing polling for new blocks
* High-frequency trading applications on Monad's fast block times

### Error Handling

| Status Code | Error Message | Cause                            |
| ----------- | ------------- | -------------------------------- |
| 403         | Forbidden     | Missing or invalid ACCESS-TOKEN. |

### Web3 Integration

{% tabs %}
{% tab title="Ether.js" %}
{% code overflow="wrap" %}

```javascript
import { ethers } from "ethers";
const RPC_URL = "https://go.getblock.us/<ACCESS_TOKEN>";
const provider = new ethers.JsonRpcProvider(RPC_URL);
async function fetchBlockNumberFromProvider() {
  try {
    // Call the method — this will resolve to a number (promise resolves to number)
     const result = await provider.send("eth_blockNumber", [],);
    console.log("Block number result:", result);
    return result;
  } catch (error) {
    console.error("Ethers Error fetching block number:", error);
    throw error;
  }
}
```

{% endcode %}
{% endtab %}

{% tab title="Viem" %}

```jsx
import { createPublicClient, http } from "viem";
import { hyperEvm } from "viem/chains";

// Create Viem client with GetBlock
const client = createPublicClient({
  chain: hyperEvm,
  transport: http(import.meta.env.MONAD_ACCESS_TOKEN),
});

// Using the method through Viem
async function Call() {
  try {
    // Method-specific Viem implementation
    const result = await client.request({
    "method": "eth_blockNumber",
    "params": [],
};
    return result;
  } catch (error) {
    console.error("Viem Error:", error);
    throw error;
  }
}
```
