These institutions may use your internet for things like checking how certain websites appear in different regions.

We checked
Testing was inconclusive because no client could be run and no live traffic destinations could be observed.
To settle it Run a Grass client and examine its connection activity and network-use documentation; validate any traffic and destination claims independently.
Skeptic: plausible Grass describes a technically coherent bandwidth-sharing and public-web-data service, with use cases such as checking how websites appear in different regions. The pages explain the intended model, but do not independently establish customer demand or the claimed institutions’ identities.
We used it: inconclusive Documentation supports the project's stated model, not independent confirmation of actual live traffic. No SOL/token transaction was relevant to this bandwidth-sharing claim, and no wallet request was presented. The needed executable client and traffic observation were unavailable.
