Blocknative

Blocknative is a developer-focused platform that delivers real-time gas fee estimation, mempool data, and transaction monitoring services to improve blockchain transaction efficiency and transparency. Founded in 2018, Blocknative is the core team behind Gas Network, an onchain global gas protocol designed to decentralize critical data infrastructure and optimize transaction fee markets across Layer 1 and Layer 2 blockchains. The platform supports Ethereum and several major Layer 2 chains including Optimism, Arbitrum, Base, Polygon, and Sei, with plans to expand further.

Blocknative’s primary features include high-frequency gas fee estimation (over 600 estimates per second), gas price prediction, historical mempool data archives, and wallet onboarding tools. These capabilities help developers and protocols optimize transaction costs, improve user experience, and troubleshoot network issues. The platform offers a gas fee estimator available as a web page and browser extension, enabling users to price transactions accurately in real time. Blocknative also plans to launch onchain oracles via Gas Network to further decentralize gas market data.

What sets Blocknative apart is its focus on making gas markets transparent and programmable, backed by extensive research and collaboration with leading protocols and wallets. Its infrastructure is trusted by top builders to enhance performance and fee optimization across multiple chains. Blocknative also actively contributes to the ecosystem through research on MEV (Miner Extractable Value) and Ethereum’s evolving fee markets. Developers can get started quickly using open-source APIs and SDKs, with comprehensive documentation and an active Discord community for support.
