Frequently asked questions
Are these crypto tools free to use?
Yes. All eleven tools are free and require no account or wallet connection. They use manual inputs and perform calculations in the browser.
Do the tools use live cryptocurrency prices?
No. Calculator inputs are manual, even though other parts of Compyvila display market data. Enter consistent, timestamped prices where a calculation needs them.
Which tools can I use without a price feed?
BTC-to-satoshi and ETH-to-wei conversions use fixed unit relationships. The other calculators use your own price, rate, supply, date or campaign inputs. None requires an external API.
