Blocknative

Blocknative is a Web3 infrastructure provider specializing in real-time mempool data, gas fee estimation, and transaction monitoring. Its core product suite includes high-frequency gas price prediction APIs (over 600 estimates per second), historical mempool data archives, wallet onboarding tools, and the Gas Network—an onchain protocol designed to decentralize gas price data across Ethereum and major Layer 2 chains like Optimism, Arbitrum, Base, Polygon, and Sei.

The company's core value proposition lies in making gas markets transparent and programmable. It addresses the industry-wide pain point of inaccurate fee estimation and unpredictable transaction costs, which often lead to failed transactions and poor user experience. By providing granular mempool visibility, Blocknative helps developers optimize transaction timing, reduce costs, and troubleshoot network issues.

In the past six months (February to August 2026), Blocknative underwent a significant transition. The company announced it was winding down operations, with its API services and Gas Network scheduled to shut down after June 19, 2026. This followed a year of contraction, including layoffs in 2025 and the earlier suspension of its MEV-Boost Relay service. The Blocknative team was acquired by Deloitte in a talent-focused deal, marking a notable case of traditional professional services firms absorbing crypto-native infrastructure expertise. This development signals a broader industry trend of consolidation and the growing intersection between traditional audit/compliance and blockchain infrastructure.
