eth_getBlockByNumber on Lisk

Supported on SwiftNodes

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

Header fields	26
Transactions per block	1, 1, 1, 1, 1 in five consecutive blocks
Response size, full transactions (true)	2.7 KB average
Response size, hashes only (false)	1.8 KB
Gas limit	60,000,000
Gas used in the latest block	46,242 (0.077% of the limit)
Base fee	1,015 wei
Tag "safe"	block 38,579,336
Tag "finalized"	block 38,579,336
Tag "pending"	block 38,583,884
Tag "earliest"	block 0

What is different on Lisk

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.

5 of the 5 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 4,546 blocks (about 2.5 hours) behind the head.

A real Lisk block header

From block 38,583,880, as our endpoint returned it (long hex values shortened).

Example request

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

// Header plus transaction hashes (1.8 KB)
const block = await client.getBlock({ blockTag: "latest" });

// With full transactions (2.7 KB on average on Lisk)
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" });

Frequently asked questions

Does Lisk support eth_getBlockByNumber?

Yes. eth_getBlockByNumber answered on the SwiftNodes Lisk endpoint when our weekly probe called it through the customer path (2026-10-13).

How many transactions are in each Lisk block?

In five consecutive blocks on 2026-10-13: 1, 1, 1, 1, 1.

Lisk endpoints, live block height and WebSocket status are on the Lisk RPC page.

One key covers every chain we serve, and SwiftNodes has a free tier.
