Mainnet, Recent State, and
Streams in One Dashboard.

MegaETH builders need more than basic RPC. Quicknode runs the full surface: low-latency JSON-RPC, trace and debug on recent state, and real-time Streams, all from one dashboard.

Data Access for Every MegaETH Workload

Query, subscribe, and stream MegaETH data with low latency. From a single JSON-RPC call to a ~15-day historical state window, you get the right interface for the job.

JSON-RPC over HTTPS and WSS on MegaETH Mainnet
Trace and debug against a ~15-day state window; blocks and transactions retained indefinitely
Streams for backfill and real-time MegaETH blocks, logs, and traces
Webhooks for push notifications on addresses and events
WebSocket subscriptions with eth_subscribe for new blocks and logs
// Build & Ship

EVM Tooling You Already Know

The Ethereum toolchain you already know works unchanged on MegaETH. Deploy contracts, manage endpoints, and ship from one Quicknode account.

Deploy and verify Solidity contracts with Hardhat, Foundry, and Remix
Token authentication, rate-limiting, JWT, and whitelisting on every endpoint
ethers.js, web3.js, viem, and @quicknode/sdk supported out of the box
Debug and trace against a ~15-day recent-state window

// Every MegaETH Data Pattern

The Full Data Suite.
Every MegaETH Data Pattern.

Six ways to access MegaETH data, from a single JSON-RPC call to Streams. Historical state is a ~15-day window; blocks and transactions are kept indefinitely.

MegaETH JSON-RPC

Standard JSON-RPC over HTTPS and WSS on MegaETH Mainnet. Every EVM method supported, including eth_call, eth_getLogs, eth_getBalance, eth_sendRawTransaction, and eth_subscribe, with predictable rate limits.

Explore Core RPC API

Streams

Backfill and real-time MegaETH blocks, logs, and traces delivered to your datastore with guaranteed reliability. Filter upstream, receive only the data you actually need.

Explore Streams

Webhooks

Event-driven alerts with guaranteed delivery. Subscribe to specific addresses, event types, or onchain conditions.

Explore Webhooks

Debug & Recent State

MegaETH keeps roughly 15 days (1,296,064 blocks) of historical state, with blocks and transactions retained indefinitely. Run debug methods against recent state for indexing and simulation.

Explore Core RPC API

Trace API

Trace MegaETH execution with trace_transaction and trace_block against recent state. Inspect internal calls for debugging and simulation.

WebSocket Subscriptions

Subscribe to new MegaETH blocks and logs over a persistent WSS connection with eth_subscribe. Push updates the moment they land, with no polling.

// Built for EVM Developers

Your Ethereum app runs on MegaETH.

MegaETH is a real-time Ethereum layer 2, so the tooling you already know works unchanged. ethers.js, web3.js, viem, and web3.py all hit a Quicknode MegaETH endpoint the same way they hit Ethereum. Same methods, same SDK, just a different RPC URL.

No rewrites

Point your existing Ethereum codebase at a Quicknode MegaETH endpoint and deploy. Contracts, libraries, and tooling carry over.

Same JSON-RPC methods

eth_call, eth_getLogs, eth_sendRawTransaction, and eth_subscribe all behave exactly as they do on Ethereum.

// Your Ethereum code, pointed at MegaETH
import { createPublicClient, http } from "viem";


const client = createPublicClient({
  // MegaETH mainnet, chain ID 4326
  chain: { id: 4326, name: "MegaETH" },
  transport: http(QUICKNODE_MEGAETH_URL)
});


const block = await client.getBlockNumber();


// Same methods, same SDK. MegaETH is a real-time Ethereum layer 2.
// Add MegaETH to MetaMask

Connect MetaMask to MegaETH in seconds.

Open MetaMask, go to Settings, Networks, Add Network, and enter your Quicknode MegaETH RPC URL with the details on the right. Save, and MetaMask routes through your private Quicknode endpoint instead of a rate-limited public RPC.
