MegaETH Onchain Data API

Get token balances, transactions, and OHLCV pricing data for MegaETH. 33 endpoints supported.

Overview

MegaETH is real-time Ethereum, streaming transactions at lightning speed: sub-millisecond latency and over 100,000 transactions per second.

This chain leverages major token prices (BTC, ETH, SOL) powered by Redstone Bolt, offering ultra-low-latency CEX price feeds updated every 2.4ms (~400 updates/sec), sourced from Binance, Coinbase, OKX, Bitget, and Kraken via co-located Bolt nodes. These price feeds are incorporated into the OHLCV Tokens Stream.
