L2 Gas Tracker

L2 Gas Tracker is a free tool that shows real-time gas fees on Base and Arbitrum in both gwei and US dollars, so you always know what a transaction will actually cost before you sign it. Live fee comparison across both networks highlights which chain is cheaper right now, while historical charts reveal the daily and weekly patterns that smart users exploit. The built-in transaction cost estimator converts any planned transfer, swap or contract interaction into an exact dollar figure using the current token price, removing the guesswork from every move. For users who want more than raw numbers, an AI advisor studies current congestion and recent trends to suggest the best moment to submit, often saving meaningful amounts on busy days. Developers can use it to time batch operations and contract deployments; traders use it to avoid overpaying during volatility spikes. No signup, no wallet connection and no fees: open the page, see the costs, act at the right time. Whether you are bridging funds, minting, or simply moving stablecoins between exchanges, L2 Gas Tracker keeps more of your money where it belongs, in your wallet.

What problem it solves
