# eth_blockNumber | Monad

> Monad API method that returns the latest block number of the blockchain. Monad developers can call eth_blockNumber via Chainstack.

Monad API method that returns the latest block number of the blockchain. A block number is a hexadecimal number representing the block's position in the blockchain.

## Parameters

* `none`

## Response

* `result` — the integer value of the node's latest block number, encoded as hexadecimal. The block number is used to identify the block's position in the blockchain and is updated every time a new block is added to the chain.

## `eth_blockNumber` code examples

<CodeGroup>
  ```javascript ethers.js theme={"system"}
  const { ethers } = require("ethers");

  const provider = new ethers.JsonRpcProvider("CHAINSTACK_NODE_URL");

  async function getBlockNumber() {
    const blockNumber = await provider.getBlockNumber();
    console.log(`Latest block: ${blockNumber}`);
  }

  getBlockNumber();
  ```

  ```python web3.py theme={"system"}
  from web3 import Web3

  node_url = "CHAINSTACK_NODE_URL"

  web3 = Web3(Web3.HTTPProvider(node_url))
  print(web3.eth.block_number)
  ```
</CodeGroup>

## Use case

A practical use case for `eth_blockNumber` is tracking the current state of the blockchain. Applications can use the current block number to determine time-sensitive operations, such as calculating when a time-locked contract will become executable or monitoring network progress.
