eth_maxPriorityFeePerGas on World Chain

Supported on SwiftNodes

Everything below was measured on 2026-10-13 by calling eth_maxPriorityFeePerGas on World Chain through the same endpoint customers use, and is re-measured weekly.

What eth_maxPriorityFeePerGas does

Returns the node's suggested priority fee (tip) per gas for an EIP-1559 transaction, in wei. Libraries such as viem and ethers fill maxPriorityFeePerGas from it by default, so its accuracy decides what your users pay.

eth_maxPriorityFeePerGas on World Chain: what we measured

Suggested tip	0.00100 gwei
Median tip paid (median of the per-block medians, last 20 blocks)	0.00100 gwei
Base fee	500,000 wei

Should you use the suggestion?

The suggestion is in line with the tips actually paid on World Chain, so the library default is fine.

Chains where the suggested tip is far above what is paid

On 28 of the chains we measure, the suggested tip was at least ten times the median tip paid (or the median paid was zero).

Example request

curl -s https://rpc.swiftnodes.io/rpc/worldchain?key=YOUR_API_KEY \
  -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"eth_maxPriorityFeePerGas","params":[]}'

import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("https://rpc.swiftnodes.io/rpc/worldchain?key=YOUR_API_KEY"),
});

// Tip from what recent blocks paid, not the node's suggestion
const { reward } = await client.getFeeHistory({ blockCount: 20, rewardPercentiles: [50] });
const tips = reward!.map((r) => r[0]).sort((a, b) => (a < b ? -1 : a > b ? 1 : 0));
const maxPriorityFeePerGas = tips[Math.floor(tips.length / 2)];

await wallet.sendTransaction({ to, value, maxPriorityFeePerGas });
