This method is available on Chainstack. Not all Hyperliquid methods are available on Chainstack, as the open-source node implementation does not support them yet — see Hyperliquid methods for the full availability breakdown.

Returns the current maximum priority fee per gas for EIP-1559 transactions. On Hyperliquid, this method always returns zero as priority fees are not used.

Parameters

This method takes no parameters.

Returns

Returns the maximum priority fee per gas as a hexadecimal string. On Hyperliquid, this is always "0x0".

On Hyperliquid, priority fees are always zero. The network uses only base fees for transaction pricing, so setting a priority fee will not affect transaction inclusion speed or priority.

Example request

curl -X POST \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_maxPriorityFeePerGas","params":[],"id":1}' \
  https://hyperliquid-mainnet.core.chainstack.com/4f8d8f4040bdacd1577bff8058438274/evm

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("YOUR_CHAINSTACK_ENDPOINT"))

max_priority_fee = w3.eth.max_priority_fee
print(max_priority_fee)

import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider("YOUR_CHAINSTACK_ENDPOINT");

const maxPriorityFee = await provider.send("eth_maxPriorityFeePerGas", []);
console.log(maxPriorityFee);

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("YOUR_CHAINSTACK_ENDPOINT"),
});

const maxPriorityFee = await client.estimateMaxPriorityFeePerGas();
console.log(maxPriorityFee);

Use your own endpoint in your code. The code examples use a placeholder Chainstack endpoint (YOUR_CHAINSTACK_ENDPOINT) — replace it with your own Hyperliquid node endpoint from the Chainstack console. The curl above uses a shared public endpoint for quick checks only; do not use it in production.

Example response:

{"jsonrpc":"2.0","id":1,"result":"0x0"}

Use cases

EIP-1559 compatibility — Maintain compatibility with EIP-1559 transaction format
Wallet applications — Handle priority fee queries for cross-chain compatibility
Fee estimation — Calculate transaction costs knowing priority fees are zero
Protocol integration — Integrate with protocols that query priority fees
