GasNow — Real-time Crypto Gas Tracker (active at gasnow.tools)

Why GasNow matters

Every interaction with a public blockchain costs money. On Ethereum the unit is gas, denominated in Gwei (one-billionth of an ether); on Bitcoin it is satoshis per virtual byte (sat/vB). Fees can swing from cents during quiet periods to tens of dollars during congestion. Checking the live price before you sign a transaction is the difference between paying $0.40 and $35 for the same swap. GasNow shows Slow / Standard / Fast tiers with the USD-equivalent cost, updated continuously, so users can decide whether to execute now or wait.
