eth_getBlockByNumber on Ronin

Supported on SwiftNodes

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

What eth_getBlockByNumber does

Returns a block by number or tag (latest, safe, finalized, pending, earliest): the header, and either the transaction hashes or the full transactions. Indexers, explorers and wallets use it to follow the chain.

eth_getBlockByNumber on Ronin: what we measured

Header fields	26
Transactions per block	104, 104, 104, 129, 130 in five consecutive blocks
Response size, full transactions (true)	75.6 KB average
Response size, hashes only (false)	8.8 KB
Gas limit	60,000,000
Gas used in the latest block	2,594,236 (4.3% of the limit)
Base fee	20.00 gwei
Tag "safe"	block 62,214,006
Tag "finalized"	block 62,213,345
Tag "pending"	block 62,214,057
Tag "earliest"	block 55,577,501

What is different on Ronin

The header includes the fields added by London (EIP-1559 base fee), Shanghai (withdrawals), Cancun (EIP-4844 blob gas), Cancun (EIP-4788 beacon root), Prague (EIP-7685 requests). Code that assumes Ethereum's current header shape will parse it as is.

Asking for full transactions (second parameter true) made the response 8.6 times larger than hashes only. If you need only some transactions, fetch hashes and request those transactions or their receipts individually.

5 of the 571 transactions in those five blocks were system transactions (5 × type 0x7e, L1-to-L2 deposit (OP Stack)). They are not user activity: filter them out when counting transactions.

"finalized" was 709 blocks (about 24 min) behind the head.

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_getBlockByNumber","params":["latest",false]}'

import { createPublicClient, http } from "viem";

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

// Header plus transaction hashes (8.8 KB)
const block = await client.getBlock({ blockTag: "latest" });

// With full transactions (75.6 KB on average on Ronin)
const full = await client.getBlock({ blockNumber: block.number, includeTransactions: true });
const userTxs = full.transactions.filter((t) => !["0x7e"].includes(t.typeHex));

// A block that will not be reorganised
const final = await client.getBlock({ blockTag: "finalized" });
