Where entries come from — and why nothing is marked "rejected" (as of 2026-10-19)
arc.io publishes an official ecosystem list. Entries beyond that list come from Circle's press releases, Arc's blog, hackathon showcases, or the teams' own announcements. Each card shows which, and the Builders Fund status is never marked rejected because Circle publishes no recipient list. arc.io/ecosystem lists partners; being listed is not an endorsement of any product's status. X handles are verified independently and are not published by Arc.

Found by the daily research bot on 2026-09-16 and reviewed by a person on 2026-09-17: the evidence post is from @MaestroBots, whose profile links only linktr.ee (still so on 2026-10-19), so the account could not be tied to the project and no handle is published. The post is therefore not treated as the project's own announcement.
