Gas across eight chains, one glance.
Live base fees and block heights from public nodes, and what a swap would cost you in dollars right now. No API keys, no accounts, no ads.
Uses the live ETH price from Jupiter and the gas price of the moment. L2s add a small data fee on top.
Your gas budget, chain by chain.
Connect an EVM wallet read-only and GasGlass reads your native balance on Ethereum, Base, Arbitrum and Optimism from public nodes, then tells you how many swaps each balance covers at this minute's gas.
Eight pumps, filling in real time.
Each tube fills relative to that chain's own typical range, so a quiet day on Base reads as quiet even though Ethereum sits far higher in absolute gwei.

Base fee vs tip
Where a chain exposes EIP-1559, the number shown is the node's suggested gas price, which already carries a small priority tip.
Public nodes only
All figures come from public RPC endpoints. If a node is slow the card dims and keeps its last reading instead of showing zero.
Why ranges differ
Gas on rollups is priced in fractions of a gwei; Polygon and Avalanche run in the tens or hundreds. The tubes normalise each chain to itself.
