Tier classification follows the same scale as the retail register: tier-1 = FCA/ASIC/CFTC-class supervision, tier-2 = CySEC/FSC-Mauritius/MFSA-class, tier-3 = offshore registration. A tier-2 licence is genuine supervision without an investor compensation scheme — never misread it as tier-1 protection.

What the firm commits to

Claims specific enough to be falsified — and the ones that remain the venue's own measurement.

A firm that publishes its own negative space — who it refuses, where it is not licensed — is materially easier to diligence than one that doesn't. The refusal list is treated here as a disclosure, not a defect.
