About

L2 Gas Tracker monitors real-time gas fees on Base and Arbitrum (Ethereum Layer 2), refreshing every 10 seconds with slow/standard/fast tiers in gwei and USD, session highs/lows, and a history chart. It includes an AI advisor that suggests the best time to transact, a fee calculator for transfers, swaps, NFT mints and approvals, and side-by-side network comparison. The site also offers an open machine-readable JSON feed, works in 9 currencies and 5 languages, and runs read-only in the browser with no wallet connection required.
