What we could not verify

Incident and legal web searches NOT run (search budget exhausted): incidents_searched=false, legal_searched=false; empty legal list means NOT CHECKED. Not verified: OAM, other licences, proof of reserves, exchange (pro) maker/taker fees, futures. Three Arrows item: FinanceFeeds (2022-07-09) says USD 270M relates to loans to 3AC and says nothing about customer funds. Outcome of Cardiff case not verified; no SEC/NYDFS/FCA enforcement found in results.

Facts are as of 9 Oct 2026. We ran a limited number of searches per exchange, so an empty list is not proof that nothing happened. We did not check the Italian OAM register. Items from press or third parties are reports, not findings by an authority. If something here is wrong or out of date, send a correction with a source: corrections policy.
