What Blocknative does

Blocknative is a San Francisco-based Web3 infrastructure company founded in 2018 that built real-time blockchain transaction management and monitoring solutions for public blockchain networks. Its core product, Gas Network, exposed gas prediction APIs, mempool data feeds, L2 decoding capabilities, wallet onboarding tooling, an MEV auction and private order flow infrastructure, and a Transaction Distribution Network supporting Ethereum block building. The technology stack targeted both Ethereum Layer 1 and a wide range of Layer 2 networks, with technical differentiators centered on mempool visibility accuracy, domain specialization in MEV economics, and integration with major wallets and DeFi protocols.

The company's go-to-market was API-first and developer-led: open-source tooling, self-serve APIs, and direct enterprise engagement with L1/L2 networks and protocol teams. Disclosed customers included the Ethereum Foundation, Synthetix, Arbitrum, Curve, zkSync, Compound, Ledger, Phantom, Avalanche, Cow Protocol, and several other major Web3 projects. Revenue mechanics were enterprise quote-based and API subscription arrangements, though pricing was not publicly disclosed.

Blocknative raised approximately $34 million in total venture funding across rounds in 2018, 2020, 2021, and 2022, with Blockchain Capital and Foundry Group as repeat lead investors. In November 2024, the Blocknative team joined Deloitte to apply Web3 and cryptographic infrastructure work to trust, coordination, and verification gaps in agentic AI workflows at enterprise scale. As part of this transition, Blocknative Corporation is ceasing independent operations, with API services and Gas Network scheduled to wind down by June 19, 2026.

Products and services

• Gas Network A real-time gas prediction API platform for Ethereum and L2 networks that provides accurate gas price estimates and transaction landing probability for wallets, protocols, and dApps.
• Gas Estimator A real-time gas price estimation tool providing current gas prices and transaction cost forecasts for Ethereum and supported L2 networks.
• Gas Extension A browser extension that surfaces real-time gas estimates and transaction insights to wallet users and Web3 traders directly in their browser.
• Mempool Data API A real-time mempool data streaming API that delivers pending transaction visibility across Ethereum and major L2 networks for developers and protocols.
• L2 Transaction Decoding Decoding services for L2 transactions across networks such as Arbitrum, Optimism, and zkSync, exposing transaction contents and intent for downstream applications.
• Transaction Distribution Network Infrastructure for distributing transactions to block builders and validators, enabling optimized transaction landing and preconfirmation for wallets and protocols.
• Wallet Onboarding SDK A developer SDK for wallet onboarding flows that uses mempool data and gas prediction to improve wallet user experience from first transaction onwards.

Direct peers

• Figment: Blockchain infrastructure provider focused on staking, node operations, and data services. Overlaps with Blocknative's protocol-side infrastructure offerings for L1s and L2s.
• Flashbots: The leading MEV/block building infrastructure provider on Ethereum, operating MEV-Boost, MEV-Block, and the Flashbots auction. Directly comparable to Blocknative on block building, MEV auctions, and private order flow — the two were the principal competitors in Ethereum's PBS/supply chain.
• bloXroute Labs: Provides blockchain infrastructure including block propagation networks (BDN), MEV services, and gateway APIs. Competes with Blocknative's Transaction Distribution Network and mempool-adjacent infrastructure.
• Alchemy: Leading Web3 developer platform providing node infrastructure, APIs, and enhanced services including mempool/webhook functionality. Direct competitor to Blocknative's API-first developer tooling stack.
• Infura (ConsenSys): Major Ethereum and multi-chain RPC/API infrastructure provider owned by ConsenSys. Notably, one source flags ConsenSys as a Blocknative acquirer, making the competitive relationship especially intertwined.
• QuickNode: Multi-chain node infrastructure and API provider serving Web3 developers and enterprises. Competes with Blocknative for developer wallet, gas estimation, and transaction monitoring workloads.
• Chainstack: Provides blockchain node infrastructure and APIs across multiple networks. Comparable to Blocknative as API-first developer infrastructure targeting enterprise and protocol customers.
• Blockdaemon: Institutional-grade blockchain node infrastructure and staking provider. Comparable to Blocknative in serving enterprise and protocol customers requiring reliable, monitored blockchain connectivity.

Emerging players

• Dune Analytics: On-chain data analytics and dashboards platform. Overlaps with Blocknative's blockchain data/monitoring capabilities, particularly around mempool and transaction data products.

Broad incumbents

• EigenLabs (EigenLayer): Restaking and AVS infrastructure provider expanding into broader crypto infrastructure services. Competes for the attention and budget of Ethereum-aligned protocols that Blocknative also serves.
