Crypto calculators and blockchain data tools
Calculators that show their working, and guides in plain language. Every page states the formula it uses, the assumptions behind it, and what it cannot tell you.

Available now
This is everything that exists today. The other calculators are being built and ship one at a time — we would rather have one working tool than ten empty pages.
Why these numbers can be trusted
- The formula is on the page
- Every calculator lists the formula, the units and the conventions it uses — a 365-day year, for instance — so you can check the arithmetic yourself.
- Assumptions and limits, stated together
- What a tool cannot do is spelled out: no slashing, no lock-up, no fees or taxes, and any price scenario is your assumption rather than a forecast.
- Author, reviewer and update date
- Each page names who wrote it, who checked it and when it last changed. Nothing that could affect a financial decision is published anonymously.
- We never touch your assets
- The whole site is read-only: no account, no wallet connection, no seed phrase, no trading and no custody.

Market data ships only once a licensed data source is in place. Until then you will not see a price, a TVL figure or a yield on this page — placeholder numbers are worse than no numbers.
