The archive · Five tools · No live prices
The tools
Four reference tables and one identifier. None of them quotes a price, none of them predicts anything, and none of them pretends to be live.
That last point is deliberate and worth stating plainly. Where a figure moves, the page says which month it was taken and links to where the current one is published. A static page that displays a changing number without a date is a page that becomes quietly wrong, and there are enough of those already.
Five of the fourteen have a documented, dated supply event. The other nine do not, and the page lists them too, with the reason. Every row carries a source link.
Block timing, how finality is actually reached, what it takes to participate, and the known trade-offs. Sortable and filterable, with no ranking column and no plans for one.
All fourteen on one sortable table: maximum supply, what kind of ceiling that is, how new units appear, whether anything burns, and whether a schedule governs release.
Flat fee, gas auction, metered base fee, rented resource. The model is the part that stays true when the price does not, so this page describes models and gives orders of magnitude only.
Which chain might this address format belong to?
Paste an address and it identifies the chain, verifies the checksum where one exists, and explains why that chain's addresses are shaped the way they are. Runs entirely in your browser.
There is no calculator here, and there will not be one
Profit calculators, yield estimators and price converters all work the same way: you supply an assumption, the tool multiplies it out, and the result looks like information because it has decimal places. It is not information. It is your assumption in a nicer font.
What these pages do instead is set out mechanisms that are true regardless of price, with the month each was checked and a link to where it was checked. That is less satisfying and it stays correct longer.
