ETH Gas Tracker

Before you hit Send on a swap, bridge, or mint, open ETH Gas Tracker and sanity check the cost. The dashboard shows live fee tiers across mainnet and major rollups, plus a simple estimator so you can paste the expected gas units and see the total in native token and USD. Set a target threshold, turn on alerts, and wait for the ping instead of refreshing your wallet every minute. When the notification lands, copy the suggested EIP-1559 values and push the transaction with confidence.

Creators and collectors can use the heatmap to pick calmer windows for activity. Plan an NFT drop, coordinate a batch of listings, or run airdrops when the network is quieter. If you operate across networks, compare mainnet against Arbitrum, Optimism, Base, zkSync, and others in one view, including rollup data costs that often skew totals. For bridging, preview the combined outlay by adding bridge fees and gas in a single what-if, then decide whether to wait, reroute, or split tasks into cheaper chunks.

Developers and power users can make it part of their workflow. Pull the API in a keeper or bot to cap spending, selecting slow, standard, or fast presets that map to realistic confirmation times. Use the CLI in CI to block deployments when fees exceed your ceiling, and export historical data to tune budgets. The tool surfaces base fee and priority tip suggestions, plus a safety band to avoid stuck transactions without overpaying. When conditions shift, webhooks fire so you can adapt pricing logic immediately. more
