Never overpay for gas again
Real-time Bitcoin, Ethereum and Layer-2 network fees — with custom alerts that ping you the instant gas drops below your target price.
Four speed tiers, one glance
Every chain shows Slow, Standard, Fast and Rapid pricing with the USD cost of a transaction — so you always know the trade-off between speed and cost.
Everything a fee-watcher needs
Built for traders, minters and anyone who hates paying peak-hour gas.
Real-time gas, every chain
Bitcoin, Ethereum, Polygon, X Layer, BOB, Bitlayer, Gravity and Duckchain — refreshed automatically every 15 seconds.
