Real-time mempool data, transaction monitoring, and gas estimation
Last updated: July 2026
Blocknative is a Web3 infrastructure provider specializing in real-time mempool data, transaction monitoring, and gas estimation — the pre-confirmation layer that most tools ignore. Its core value is visibility into pending transactions: Blocknative streams mempool events so applications can track a transaction's lifecycle in real time (submitted, pending, confirmed, dropped, replaced), notify users accurately, and react to on-chain events before they're mined. Its Gas Platform provides accurate, real-time gas-price estimation and prediction, widely used by wallets and dApps to set optimal fees, and it offers transaction-preview/simulation and MEV-related data. This pre-chain, mempool-focused tooling is genuinely differentiated — most providers only see confirmed data. It offers APIs and SDKs with free and paid tiers. The trade-offs: mempool infrastructure is specialized (most apps that just read confirmed data don't need it), the mempool is increasingly private/complex due to MEV (private orderflow means not all transactions are publicly visible), and it's a focused tool rather than a full development platform. But for developers building wallets, dApps, or trading tools that need accurate real-time transaction tracking, gas estimation, or mempool visibility — the pre-confirmation experience that makes apps feel responsive and reliable — Blocknative provides specialized, best-in-class infrastructure that general RPC providers don't.
