eth_maxPriorityFeePerGas on Scroll

Supported on SwiftNodes

Everything below was measured on 2026-10-13 by calling eth_maxPriorityFeePerGas on Scroll 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 Scroll: what we measured

Suggested tip	100 wei
Median tip paid (median of the per-block medians, last 20 blocks)	100 wei
Base fee	120,008 wei

Should you use the suggestion?

The suggestion is in line with the tips actually paid on Scroll, 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/scroll?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/scroll?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 });
