eth_maxPriorityFeePerGas on Ronin

Supported on SwiftNodes

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

Suggested tip	0.00100 gwei
Median tip paid (median of the per-block medians, last 20 blocks)	2.00 gwei
Base fee	20.00 gwei

Should you use the suggestion?

The suggestion is below the median tip paid, so transactions using it may wait behind others when blocks fill. Use a higher percentile from eth_feeHistory if inclusion time matters.

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/ronin?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/ronin?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 });
