eth_maxPriorityFeePerGas on Shibarium

Supported on SwiftNodes

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

Suggested tip	1.50 gwei
Median tip paid (median of the per-block medians, last 20 blocks)	0 wei
Base fee	15 wei

Should you use the suggestion?

Most transactions on Shibarium paid no tip at all, yet the node suggests 1.50 gwei. Blocks are not full, so a zero or minimal tip is included just as fast.

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/shibarium?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/shibarium?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 });
