OnyxCard fails to provide ownership or executive information on its website.

In fact as I write this, OnyxCard’s website is nothing more than a sign-in form:

OnyxCard’s website domain (“onyxcard.pro”), was privately registered on December 27th, 2025.

On the subdomain “info.onyxcard.pro”, OnyxCard provides a Terms and Conditions page. On this page we learn “OnyxCard is operated by Vault27 Limited”:

Vault27 is a “staking” model MLM crypto Ponzi run by Bruce John Curnick.

Why Curnick’s ownership isn’t disclosed on OnyxCard’s website is unclear.

As always, if an MLM company is not openly upfront about who is running or owns it, think long and hard about joining and/or handing over any money.

OnyxCard’s Products

OnyxCard has no retailable products or services.

Promoters are only able to market OnyxCard promoter membership itself.

With a minimum 100 USDT deposit, OnyxCard provides access to a VISA debit card;

OnyxCard connects your crypto to the real world. Spend USDT anywhere Visa is accepted – online, in-store, or on the go – with a $100k daily spending limit and zero monthly fees.

OnyxCard charges a 5% balance top-up fee and 5% withdrawal fee.

Replacement cards are 25 USDT and OnyxCard drains balances of “inactive” accounts by 5 USDT a month after 12 months of inactivity (inactivity is assumed to refer to transactions).

OnyxCard’s Compensation Plan

OnyxCard promoters sign up and pay 100 USDT for access to a VISA debit card.

OnyxCard uses this fee to pay referral commissions via a unilevel compensation structure.

A unilevel compensation structure places a promoter at the top of a unilevel team, with every personally recruited promoter placed directly under them (level 1):

If any level 1 promoters recruit new promoters, they are placed on level 2 of the original promoter’s unilevel team.

If any level 2 promoters recruit new promoters, they are placed on level 3 and so on and so forth down a theoretical infinite number of levels.

OnyxCard caps payable unilevel team levels at nine. Referral commissions are paid on 100 USDT promoter fees paid across these nine levels as follows:

  • level 1 (personally recruited promoters) – $25
  • level 2 – $12
  • level 3 – $9
  • level 4 – $5
  • levels 5 to 7 – $3
  • levels 8 and 9 – $2

OnyxCard also shares 2% of the 5% it charges on card top-ups. This 2% is split across the same nine unilevel team levels:

  • level 1 – 1%
  • level 2 – 0.3%
  • level 3 – 0.2%
  • levels 4 to 7 – 0.1%
  • levels 8 and 9 – 0.05%

Joining OnyxCard

OnyxCard promoter membership is free.

Full participation in the attached income opportunity requires a 100 USDT fee payment.

OnyxCard Conclusion

OnyxCard is likely the result of Vault27 being unable to sign up with a legitimate payment processor.

Obviously VISA doesn’t touch cryptocurrency. The typical set up with “crypto cards” is a dodgy VISA merchant is created, purchased or partnered with.

This dodgy merchant presents a “clean” face to VISA. On the backend you have companies like OnyxCard and Vault27, who handle crypto currency conversions.

VISA transactions are protected by their security system. The dodgy in-house conversion OnyxCard and Vault27 do is not:

SERVICE PROVIDED ‘AS IS’. We are not liable for indirect damages, lost profits, crypto volatility, or blockchain failures.

It’s unclear whether Vault27’s Costa Rica shell company, Vault27 Limited, or another company is tied to the dodgy merchant supplying VISA cards.

If anyone calls up VISA and asks for assistance with OnyxCard’s VISA cards, they’re unlikely to know anything about OnyxCard or Vault27.

This presents an ongoing risk for OnyxCard’s promoters, with VISA able to disable cards on detection of fraud at any time.

All that aside, the MLM side of OnyxCard operates as a pyramid scheme. Nothing is marketed or sold to retail customers, with 100% of commissions paid out sourced from recruited promoters.

As with all MLM pyramid schemes, once promoter recruitment dries up so too will commissions.

This will see those at the bottom of OnyxCard’s MLM opportunity eventually take a loss. That’ s on top of Vault27 losses if OnyxCard promoters also sign up for the “staking” Ponzi scheme.

Math guarantees that when a pyramid scheme or Ponzi scheme collapses, the majority of participants lose money.
