Onyx Treasury · Private Wealth Vault

A Swiss Numbered
Account, Rebuilt.

A private wealth vault for traditional currency and digital dollars. One discreet account. One metal key. No name on the account, no public register, no searchable trail. Confidential to the world, accountable to the law.

Your Treasury Opens

Balances, transfers, and history — instantly. In your browser, on any device.

Why Metal

Software leaks.
Metal endures.

No App Store

Works on any phone with a browser. Nothing to download, nothing to update.

No Digital Key

The key is physical. It cannot be phished, exfiltrated, or copied remotely.

Biometric + PIN

Two factors at minimum. You are the second key — always.

Laser-Engraved QR

A permanent backup, etched into metal. It never fades, never corrupts.

Identity Sealed

Verified once, then locked inside the vault. Never sold, never shared, never visible. Except to lawful authority, and in the annual tax report required by international law.

Premium Metal

Aerospace-grade stainless steel or tungsten. Built to outlast its owner.

The Vault

What Swiss banks
used to do.

Open an account and become a number. To counterparties and the outside world, you are a vault number and nothing more. Your identity is verified once by our licensed partner institution, then sealed — they know exactly who you are, and that is precisely what makes this lawful. Inside: both worlds of money, under one sovereign view.

Confidentiality from the world · Accountability to the law

·01

Numbered & Confidential

No name on the account. No searchable trail. Your identity is verified once, then sealed. It is never sold, never shared, never visible — except to a regulator or court with a lawful demand.

·02

Fiat + Digital Dollars

Hold euros, dollars, dirhams and USDC in one place. Deposits, withdrawals, and conversions are executed by our licensed European partner institutions.

·03

Global & Discreet

For private clients internationally, subject to our client acceptance policy and the requirements of our partner institutions. Access your treasury from anywhere.

·04

Legal Privacy

The standard Swiss private banking operated on for a century: confidentiality from the world, accountability to the law. Confidential — never anonymous: every client is fully identified before a vault is opened. Your vault is disclosed only to a competent authority acting with lawful process, and through the annual tax report required by international law.

Plain language

What Onyx Treasury
is not.

Not a bank account with WPE.

WPE Investments is not a bank or credit institution. Your account is held by our licensed partner institution.

Not a way to step outside your tax obligations.

Accounts are reported to your country of residence under CRS, and under CARF for digital assets, as international law requires. We do not advise on, or assist with, avoiding tax reporting.

Not available without identity verification.

Every client is fully identified before a vault is opened. We decline every request for anonymity, without exception.

Confidential — never anonymous. Every client is fully identified before a vault is opened.
