About
Show the whole book.
Every onchain venue publishes its order book to anyone who asks. Few people read those books before they trade. Glassy reads them in the open and shows what they hold, so you can see the depth behind a price before you trust it.
What this is for
Markets you can see into.
Onchain venues split the same asset across dozens of books, and the desks that serve them keep their measurements to themselves. You end up trading on the price you can see, with no view of what stands behind it.
Glassy puts the same measurements in front of everyone at the same moment. A venue with a thin book learns it from the same screen its traders use, and a trader learns it before sending size.
01
Show the working
Every figure names where it came from and when. The terminal runs in your browser: open the network tab and watch the requests leave for the venues.
02
One yardstick
A new book on Robinhood Chain and the largest perp exchange go through the same code. No venue gets a shortcut and none gets a handicap.
03
A gap, not a guess
When a feed drops, its reading turns to a dash and stops counting toward anything. Nothing here is carried over from the last good number.
04
Nothing about ourselves
The counters measure the sockets this tab opened. Close it and they stop. No number on this site describes how big Glassy is or who uses it.
05
Say where it runs out
Each note ends on what the measurement cannot see: the size that never reached the book, the venue that reports its own volume, the feed that updates twice a day.
