# eth_call | Monad

> Monad API method that executes a new message call immediately without creating a transaction on the blockchain. Monad via Chainstack.

Monad API method that executes a new message call immediately without creating a transaction on the blockchain. This is useful for reading data from smart contracts or simulating transactions.

<Note>
  **Monad-specific behavior**:

  * Calls reliant on old state (with an old block number) may fail, because full nodes do not provide access to arbitrary historic state.
  * Does not accept EIP-4844 (blob) transaction type, as EIP-4844 is not supported on Monad.
</Note>

<Note>
  When called against a block older than the latest \~128 blocks, this method is treated as an archive request (2 RUs instead of 1 RU). See [request units](/docs/request-units#archive-state-methods).
</Note>

## Parameters

* `object` — the transaction call object:
  * `from` (optional) — address the transaction is sent from
  * `to` — address the transaction is directed to
  * `gas` (optional) — gas provided for the call
  * `gasPrice` (optional) — gas price for the call
  * `value` (optional) — value sent with the call
  * `data` (optional) — hash of the method signature and encoded parameters
* `quantity or tag` — integer block number, or the string `latest`, `earliest`, or `pending`

## Response

* `result` — the return value of the executed contract call.

## `eth_call` code examples

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

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

  async function callContract() {
    // Call name() on Wrapped Monad (WMON) contract
    const result = await provider.call({
      to: "0x760AfE86e5de5fa0Ee542fc7B7B713e1c5425701",
      data: "0x06fdde03" // name()
    });
    console.log(result);
  }

  callContract();
  ```

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

  node_url = "CHAINSTACK_NODE_URL"

  web3 = Web3(Web3.HTTPProvider(node_url))

  # Call name() on Wrapped Monad (WMON) contract
  result = web3.eth.call({
      'to': '0x760AfE86e5de5fa0Ee542fc7B7B713e1c5425701',
      'data': '0x06fdde03' # name()
  })
  print(result.hex())
  ```
</CodeGroup>

## Use case

A practical use case for `eth_call` is reading data from smart contracts, such as token balances, contract state variables, or simulating complex transactions before sending them.
