Every session moves through the same five stages, whether the visitor connects a wallet or stays a guest.
1 · LANDING
Landing
Interactive satellite globe with example signal sites. Anyone can look.
2 · CONNECT
Connect
Injected wallet switches to Robinhood Chain and signs a free, gasless SIWE message.
3 · EXPLORE
Explore
Click a location, ask a question, get a change report with polygons, datasets and confidence.
4 · WATCHTOWERS
Watchtowers
Draw a polygon, pick detection rules, frequency and duration for a recurring monitor.
5 · RECEIPTS
Receipts
Every finding gets a timestamped, hashable receipt that can be anchored onchain.
Explore
Explorer access allows 5 analyses per week and 1 active watchtower; guests get 3 free analyses (tracked per cookie and per IP) with no wallet at all. Each analysis runs the real Sentinel-2 pipeline and returns hectare-measured change polygons, the scenes and datasets used, a confidence score and a SHA-256 report hash that commits to the exact scene IDs. A Compare imagery toggle overlays two dated snapshots from the Esri Wayback archive with a blend slider, and the place-search box (Nominatim) flies the map anywhere by name.
Watchtowers
A Watchtower is a recurring monitoring job: a polygon, a set of detection rules, a check frequency and a duration. Creation sends a real createWatchtower transaction; the polygon and rules stay private, and only their keccak256 hashes go to WatchtowerRegistry with ownership and expiry. A background runner sweeps every five minutes, executes due monitors, and records sightings: a one-line summary, findings, confidence and a report hash, each of which also lands in your receipts.
Receipts
Anchoring a receipt writes its report hash to Robinhood Chain through commitAnalysis or commitStandalone, proving the finding existed at that time and was not rewritten later. The public /verify page checks any hash against the chain directly — paste a hash, get the anchoring transaction, block and timestamp, no account needed.
GeoSignals
The Signals tab links physical-world events to the entities behind them and, where one exists, to the canonical Robinhood Stock Token for an exposed company (with Blockscout links). Each signal can be dropped straight onto the map for investigation. It is informational only and deliberately contains no prices or calls to action.
