# eth_maxPriorityFeePerGas | Monad

> Monad API method that returns a suggestion for the max priority fee per gas (tip) to use in EIP-1559 transactions. Monad via Chainstack.

Monad API method that returns a suggestion for the max priority fee per gas (tip) to use in EIP-1559 transactions. This method helps you determine an appropriate tip to incentivize validators to include your transaction.

<Note>
  **Monad-specific behavior**: Currently returns a hardcoded suggested fee of 2 gwei. This is temporary and will be updated with dynamic fee estimation in the future.
</Note>

## Parameters

* `none`

## Response

* `result` — the suggested max priority fee per gas in wei, encoded as hexadecimal.

## `eth_maxPriorityFeePerGas` code examples

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

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

  async function getMaxPriorityFee() {
    const maxPriorityFee = await provider.send("eth_maxPriorityFeePerGas", []);
    console.log(`Max priority fee: ${parseInt(maxPriorityFee, 16)} wei`);
    console.log(`Max priority fee: ${ethers.formatUnits(maxPriorityFee, "gwei")} gwei`);
  }

  getMaxPriorityFee();
  ```

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

  node_url = "CHAINSTACK_NODE_URL"

  web3 = Web3(Web3.HTTPProvider(node_url))
  max_priority_fee = web3.eth.max_priority_fee
  print(f'Max priority fee: {max_priority_fee} wei')
  print(f'Max priority fee: {web3.from_wei(max_priority_fee, "gwei")} gwei')
  ```
</CodeGroup>

## Use case

A practical use case for `eth_maxPriorityFeePerGas` is dynamically setting the priority fee for EIP-1559 transactions to ensure competitive inclusion times while avoiding overpaying during low-congestion periods.
