Gas Estimator
See current Ethereum gas and rough costs for common actions — and judge whether a "claim fee" is plausible or a scam.
Live Ethereum gas, proxied through TokenSpin (no third-party scripts). Use it to sanity-check whether a "fee to claim" is realistic — a demand for a large upfront fee to "unlock" a reward is a classic scam.
