Company profile
researched Aug 2026Blocknative is a blockchain infrastructure company founded in 2018 that provided real-time observability and optimization tooling for public blockchains, with a focus on Ethereum and other EVM-compatible Layer 1 and Layer 2 networks. Its products included gas prediction APIs, mempool data streams, Layer 2 transaction decoding and wallet onboarding tooling, positioned for both network operators (L1s and L2s) and application builders seeking accurate fee estimation, wallet connection, transaction monitoring and troubleshooting.
The company described itself as the core development team behind Gas Network, a decentralized oracle network supplying real-time gas pricing data across more than 40 networks, with a stated aim of decentralizing critical data infrastructure and improving transaction efficiency. Over its history Blocknative also worked on mempool visibility, transaction orchestration, block building, MEV auctions, private order flow and transaction pricing.
In May 2026 Deloitte acquired the Blocknative team in a talent-focused deal, with the team directed to Web3 innovation work across Deloitte's client portfolio. Blocknative Corporation entered a process of ceasing operations; its API services and Gas Network are scheduled to continue only through June 19, 2026, after which the APIs stop responding and customers must migrate to other providers.
Founding story
The company was founded in 2018 by Matt Cutler, who served as founder and chief executive officer, with the stated goal of making onchain systems more reliable for the people who build and use them.
Business model
Blocknative sold blockchain data and transaction infrastructure to protocol teams, wallet builders, application developers and institutions, delivered primarily as APIs and developer tooling, alongside open-source components such as wallet onboarding libraries. It also operated Gas Network, a decentralized oracle network distributing real-time gas fee pricing data.
Revenue derived from paid access to its blockchain data and transaction APIs and related infrastructure services for networks, builders and enterprises.
Traction
Blocknative reported raising around $34 million from investors, operated a gas oracle network covering more than 40 networks, and counted the Ethereum Foundation, Curve Finance and Tally among the companies it served.
Latest developments
In May 2026 Deloitte acquired Blocknative's team in a talent acquisition, and Blocknative announced it is ceasing operations. Its API services and the Gas Network will operate through June 19, 2026 and then shut down, with customers advised to begin migration planning. Coverage placed the wind-down within a broader wave of crypto infrastructure consolidation and closures.

Market position
Blocknative was an established Ethereum-ecosystem infrastructure provider whose gas, mempool and wallet tooling was used by protocol teams, wallet builders and institutions, with reported customers including the Ethereum Foundation, Curve Finance and Tally, before winding down in 2026.
Blocknative combined real-time mempool visibility with gas fee prediction and transaction orchestration in a single infrastructure stack, and operated Gas Network as a decentralized oracle for gas pricing across more than 40 networks rather than a single chain.
Technology
Real-time mempool monitoring, gas fee prediction APIs, Layer 2 transaction decoding, transaction monitoring and orchestration, wallet onboarding libraries, block building and MEV auction systems, a Transaction Distribution Network, and Gas Network, a decentralized oracle network for gas pricing data.
Go-to-market
Distribution was developer-led, through public APIs, open-source tooling and documentation aimed at builders, plus direct engagement with Layer 1 and Layer 2 network operators, protocol teams and institutions. The company also maintained a public research and media presence, including podcast and conference appearances by its CEO on MEV and the Ethereum Merge.
Layer 1 and Layer 2 blockchain networks, application and wallet developers, protocol teams, researchers and institutions; named users include the Ethereum Foundation, Curve Finance and Tally.
Geography
Headquartered in San Francisco, serving blockchain networks and developers globally.
History
Founded in 2018, Blocknative built real-time mempool monitoring, gas fee prediction and transaction management products, and later worked on block building, MEV auctions, private order flow and a Transaction Distribution Network. It raised $15 million in a round covered by Fortune to expand Ethereum infrastructure and block building, and by 2026 had raised roughly $34 million in total. In May 2026 Deloitte acquired the Blocknative team in a talent-focused transaction; the company announced it was ceasing operations, with its APIs and Gas Network scheduled to stop functioning on June 19, 2026.
Risks & controversies
The company is ceasing operations following the Deloitte talent acquisition, and its APIs and Gas Network will stop responding after June 19, 2026, requiring dependent teams to migrate providers. It is not a full company buyout, and reports state it is unclear whether the entire team will join Deloitte.
