eth_getBlockByNumber on Linea

Supported on SwiftNodes

Everything below was measured on 2026-10-13 by calling eth_getBlockByNumber on Linea 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 Linea: what we measured

Header fields	26
Transactions per block	4, 1, 1, 1, 1 in five consecutive blocks
Response size, full transactions (true)	3.6 KB average
Response size, hashes only (false)	2.0 KB
Gas limit	2,000,000,000
Gas used in the latest block	375,669 (0.019% of the limit)
Base fee	7 wei
Tag "safe"	block 32,310,799
Tag "finalized"	block 32,311,940
Tag "pending"	block 32,311,941
Tag "earliest"	block 0

What is different on Linea

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.

A real Linea block header

From block 32,311,939, as our endpoint returned it (long hex values shortened).

Example request

curl -s https://rpc.swiftnodes.io/rpc/linea?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/linea?key=YOUR_API_KEY"),
});

// Header plus transaction hashes (2.0 KB)
const block = await client.getBlock({ blockTag: "latest" });

// With full transactions (3.6 KB on average on Linea)
const full = await client.getBlock({ blockNumber: block.number, includeTransactions: true });

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