Ethernow
Ethernow provides real-time and historical Ethereum mempool transaction data and block composition metrics.
Overview
Ethernow is a real-time Ethereum mempool monitoring tool developed by Blocknative. It enables developers and analysts to observe transactions as they enter the public mempool, track their status changes from pending to finalization, and analyze historical block data. Users can access detailed metrics on block composition, including ratios of private versus public transactions, externally owned accounts (EOA) versus smart contract interactions, and fee recipient distributions. The platform also provides full JSON payloads for each transaction, allowing deep inspection of transaction data.
Designed for developers, DeFi teams, and analytics professionals, Ethernow helps users understand transaction flows and mempool dynamics on Ethereum. It supports filtering and saving custom views of mempool data, which can be shared with communities for collaborative research. This granular visibility into transaction lifecycle and block makeup aids in debugging, performance analysis, and research on Ethereum network behavior.
Ethernow is accessible via a web interface and backed by Blocknative's infrastructure. While it currently supports Ethereum mainnet mempool data, support for Ethernow will end on March 1, 2025, as announced by Blocknative. Users can get started by visiting the Ethernow website, exploring the mempool dashboard, and using the documentation to integrate or customize filters. The tool is powered by a grant from the Ethereum Foundation, reflecting its focus on transparency and open data access for the Ethereum ecosystem.
The Problem
Developers and analysts lack easy access to real-time and historical Ethereum mempool data, making it difficult to track transaction status changes and understand block composition. This limits the ability to debug, optimize, and research transaction flows and network behavior effectively.
