## What it actually says

Luxembourg carries weight here because of what is domiciled in it rather than because of any national rule on confidentiality. It is one of Europe's main fund jurisdictions, so the questions that arise are institutional: what a regulated fund may hold, through which custodian, and what diligence the manager must do on the assets themselves. Those duties tend to bite on provenance and on who controls the keys rather than on whether amounts are public. On the narrower question this section asks, we located no Luxembourg instrument restricting anonymity-enhancing assets or self-hosted wallets, so the European baseline governs.

## The instruments that matter

- **The CSSF is the competent authority**: for authorising and supervising crypto-asset service providers
- **Why it matters disproportionately**: Luxembourg is one of Europe's principal fund domiciles, so the practical questions here are about what regulated funds may hold and through whom, rather than about retail transfers
- **The binding rules are European**: the travel rule applies with no minimum value, and from 10 July 2027 regulated firms may not keep accounts that anonymise the holder
- **No national divergence located**: we found no Luxembourg instrument restricting anonymity-enhancing assets or self-hosted wallets
