The numbered vault,
reborn.
A confidential digital vault for money and digital assets — built on the century-old discipline of Swiss private banking, rebuilt for the digital age.
One identity check. Once.
Verification is performed by our licensed partner institution when your vault is opened. Your identity then becomes a sealed, encrypted file.
From then on, you are a number.
Every statement, transfer, and conversation references your vault number only. Staff see numbers, not names.
Money moves on regulated rails.
Deposits, withdrawals, cards, and digital-asset custody are provided by licensed European institutions. Your funds never sit with WPE.
Engraved, not advertised.
Invisible to the public.
No register, no search, no data ever sold.
Invisible to counterparties.
Whoever you pay sees one transaction — never your balance, never your history.
Sealed identity.
Disclosed only to lawful authority with lawful process — a court order or the automatic tax report required by international law. Nothing less opens the file.
Confidential — never anonymous.
We know who you are. We would sooner close than tell anyone who doesn't hold a warrant.
What Onyx Treasury
is not.
