What we could not verify

Not verified: Italy onboarding/OAM, PoR, fees, products, other licenses. Incident search found no hack in sources read (CoinDesk profile lists none), results were limited.

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 If something here is wrong or out of date, send a correction with a source: corrections policy. Education only, not investment advice.
