Frequently asked questions

Are the tools free?

Yes — every calculator is free. The calculators run in your browser; the live tools (gas tracker, halving countdown) read public data.

Where do live prices come from?

CoinGecko for prices, Etherscan for gas and a public block-height feed for the halving. When a feed is unavailable we hide the live figure rather than invent one.

Are the results financial advice?

No. Every output is an illustration based on the numbers you supply and live data where shown, for information only — never a recommendation to buy or sell.
