Order Book Snapshot Transparency Live
Join CommunitySummary
Propr now records top 10 bid and ask levels for every fill using Hyperliquid WebSocket exchange timestamps. Users can open the order book snapshot from the Trades tab, check the capturedAt timestamp, and cross-reference levels with Hyperliquid L2 Book API. This makes paper trading verifiable and transparent.
We just shipped order book snapshot transparency on Propr. https://x.com/louisregis/status/2029156955764174860?s=20
Every fill now captures the top 10 bid/ask levels from Hyperliquid's order book at execution time using
Hyperliquid's own WebSocket timestamp, not ours.
You can verify any trade by:
1. Opening the order book snapshot on any trade (book icon in Trades tab)
2. Checking the capturedAt timestamp, it's Hyperliquid's exchange timestamp
3. Comparing our stored levels against Hyperliquid's L2 Book API:
Same data source, same timestamp, fully cross-referenceable. If the levels don't match, call us out.
Paper trading shouldn't be a trust exercise.
Early testers will access this feature by eow
Paper trading engines shouldn't be black boxes.
