About Blocknative

Blocknative offers real-time infrastructure for gas fee prediction, transaction simulation, and mempool monitoring. It powers reliable Web3 UX by giving developers visibility into pre-chain activity on Ethereum and other chains.

Ethereum

Blocknative is a pioneering infrastructure platform dedicated to solving Web3 gas fee challenges through precise prediction, optimization, and visibility. Since 2018, Blocknative has empowered thousands of projects—including wallets, DEXs, L2s, and dApps—with real-time gas estimation APIs and mempool analytics across 20+ blockchain networks. The platform enables developers and users to transact faster and cheaper by anticipating gas dynamics before transactions hit the chain.

Designed to handle >7,000 transactions per second globally, Blocknative offers the industry’s most comprehensive toolkit for on-chain fee optimization. From retail users and professional traders to protocol developers and enterprise builders, the Blocknative ecosystem makes mempool data accessible, actionable, and efficient for all participants in the decentralized economy.

Blocknative provides the backbone for gas intelligence across the most active Layer 1 and Layer 2 chains, including Ethereum, Polygon, Arbitrum, Base, zkSync, Optimism, and others. Its real-time Gas Platform APIs accurately forecast inclusion prices for transactions within the next block or next few seconds—reducing overpayment and avoiding failed transactions. Through its proprietary mempool infrastructure, Blocknative offers unmatched coverage and reliability.

In 2023, Blocknative expanded its impact with the launch of Gas Network—a decentralized oracle network that brings gas pricing directly on-chain. This innovation enables smart contracts and bots to autonomously make gas-aware decisions. Products like Multichain Gas APIs, ETH Gas Prediction APIs, and the Gas Distribution API serve as plug-and-play tools for wallets, dApps, bots, and cross-chain protocols. Integration takes minutes and supports mission-critical services across both DeFi and infrastructure providers.

Blocknative is trusted by key industry names such as MetaMask, Balancer, Uniswap, OpenZeppelin, Compound, Phantom, and Zapper. The team includes globally distributed engineers and researchers with deep expertise in protocol dynamics, MEV, and real-time transaction monitoring. As highlighted in thought-leader citations and technical research papers, Blocknative plays a vital role in shaping fair and transparent access to blockspace.

Compared to competitors like Alchemy, Infura, and Flashbots, Blocknative uniquely focuses on the transaction pre-confirmation layer—an often overlooked but critical moment in blockchain interaction. It brings visibility and control to what happens between transaction signing and block inclusion, solving the most misunderstood and impactful problem in Web3: how transactions get confirmed.

Blocknative provides numerous benefits and features that make it essential to the Web3 infrastructure stack:

Multi-Chain Gas Estimation: Predicts next-block inclusion prices across Ethereum, Polygon, Base, Optimism, zkSync, Arbitrum, Sei, and more.
Gas Network Oracle: Decentralized, on-chain oracle for real-time gas data with multi-chain support.
Reliable APIs: Trusted by leading wallets and protocols with >99.99% uptime and global infrastructure.
Next-Block Precision: Leverages live mempool data to estimate exact gas needed for the next block with confidence thresholds.
Advanced Tooling: Includes ETH Gas Distribution API, Gas Estimator Extension, and Base Fee Prediction API.
Research-Backed Platform: Offers technical publications, performance benchmarks, and network transparency data via its public research hub.

Getting started with Blocknative is easy for developers and teams looking to integrate gas intelligence into their apps:

Step 1: Visit blocknative.com and choose the product or API you want to use.
Step 2: Request an API key to access tools like the Gas Price API, Base Fee API, or Gas Distribution API.
Step 3: Follow detailed documentation to integrate into your wallet, bot, or dApp. Sample code is available via GitHub and NPM.
Step 4: Install the Gas Estimator browser extension for Chrome, Firefox, or Brave to monitor gas prices in real time.
Step 5: Join the Gas Network community to stay updated on gas oracle performance and upcoming features.

Blocknative FAQ

Blocknative leverages real-time mempool monitoring infrastructure and advanced predictive modeling to generate gas estimates for over 20 networks. Its Gas Platform APIs use quantile regression and machine learning to forecast the minimum inclusion price for either the next block or the next few seconds, depending on the chain. By cross-referencing actual confirmation data, Blocknative calibrates its models to ensure unmatched accuracy in volatile markets.
Gas Network by Blocknative is a decentralized, composable oracle that brings live gas price data on-chain—unifying prediction infrastructure across chains into a single real-time system. Unlike legacy oracles that rely solely on post-block data, Gas Network delivers confidence-banded gas predictions with signed on-chain values. It powers smart contract automation and MEV-aware apps with precision gas feeds. Learn more at blocknative.com.
Yes, Blocknative’s Gas Platform is designed specifically to prevent overspending while ensuring inclusion. Its Gas Price API provides tiered predictions based on urgency, so developers can choose gas fees based on desired confirmation speed. These predictions help prevent failed transactions during congestion and ensure inclusion without paying more than necessary. The system is used by MetaMask, OpenZeppelin, and many DeFi protocols. Try it via Blocknative.
Blocknative offers gas prediction and transaction monitoring across top Layer 2s like Arbitrum, Base, Optimism, and zkSync. The APIs and browser extension support real-time visibility into fee markets, helping builders manage bridging, bundling, and L1<>L2 interactions. These features ensure smoother UX, predictable costs, and better user retention. Builders can explore integrations via blocknative.com.
Absolutely. The Blocknative Gas Estimator browser extension is ideal for users who transact on Ethereum, Polygon, or other chains and want to avoid gas overpayment. It shows live updates for next-block pricing, base fee, and priority fees, letting users time their transactions accurately. Available for Chrome, Firefox, and Brave, the tool brings real-time mempool visibility to any Web3 user. Download it at Blocknative.
