Say hello to the Gas Extension from Blocknative - a browser add-on that shows multi-chain gas fee alerts, powered by live mempool data.
It’s built for users and builders who want real-time insight, not lagging estimates.
Why it matters: Most “gas price” tools look at past blocks or average fees. This extension inspects public-pending transactions and uses ML models to predict the next block’s minimum fee needed.
It supports a wide set of chains: Ethereum, Polygon, Arbitrum, Fantom, Gnosis Chain, Base, Blast, Optimism, Immutable, Linea, Sei + more.
Frequency advantage: For free users the extension updates every ~5 seconds. Enterprise users get updates every ~1 second. Real-time matters when blocks are racing.
Legacy & EIP-1559 support built in: Whether you’re on the classic fee model or new style, the extension handles both on chains like Ethereum & Polygon. No guesswork.
For builders: This means your dApp, wallet or DeFi UI can rely on accurate, upcoming-block fee estimates instead of stale or wasted gas. Less over-payment, fewer failed txs.
For traders and power users: If you’ve ever dealt with “why is my fee so high?” or “why did my tx take forever?” - that pain exists because you were operating blind to the mempool. This tool gives you visibility.
Social proof: Users are already calling it a “game-changer” for UX and devs alike -
“If you’re a builder or user of DeFi protocols and you aren’t paying attention to the mempool, you’re flying blind.”
TL;DR: The next wave of fee optimisation won’t be about “lower fees” alone - it’ll be about timing, alignment with the mempool, crossing the right block window. The extension helps you play that game.
