Summary
- Blocknative was founded in 2018 to build critical infrastructure for the blockchain world, including real-time gas fee estimation tooling
- Users of the Blocknative extension can now earn points for Gas Network by "Capturing the Gap"
Blocknative has made a name for itself as a true "OG" of the crypto industry, having been founded in 2018 to build critical infrastructure for blockchain networks. Their newest venture, Gas Network, aims to solve a major problem everyone in crypto deals with: gas fees. Every year crypto transactions cost users millions of dollars in fees, a number that could be lowered substantially by more efficient infrastructure like what Gas Network is building.

Blocknative offers hands down the best gas fee estimation tool in the market, now with expanded chain support beyond just Ethereum. The tool makes it easy for traders of all skill levels to know just how much they have to pay to get their transactions through in a timely manner, and more importantly how to avoid paying exorbitant fees. The extension's user interface is intuitive with the ability to save specific chains as favorites, making it easy to switch between only the ones you use most. In fact, the extension icon will display the current base fee for whichever chain you've selected, meaning you may not even have to open the extension to get the information you need.
A new addition to the extension appears in the bottom right, with the ability to earn through the Gas Network points program. Sometimes gas estimation oracles can get behind on their data, and there is an action required to make sure they're updated to the latest numbers; participating in this process takes just a few clicks, and in exchange users can earn points towards a potential future airdrop! All in all, the math here is simple: the extension is entirely free, and has the ability to save users hundreds of dollars a year – we recommend trying it.
