OnyxioN B.V
OnyxioN B.V. is a Curacao-registered gambling company. It sits behind a small group of online casino and sportsbook brands aimed mainly at players outside regulated European markets. The company set up in 2019 and later changed its name. The “OnyxioN” branding you still see quoted online now trades as Santeda International B.V. This page covers who the company is, where it holds its licence, and what that means for an Australian sizing up its sites.

Who is behind the company
The company registered in Curacao in September 2019 and ran its casinos through a Cyprus subsidiary, Onyxion Development Limited. In 2022 the group renamed both arms. The Curacao parent became Santeda International B.V., and the Cyprus operator became Santeda International Limited. The newer name is the one to follow if you are researching the group today, and you can read more on our Santeda International page. The operation stays fairly compact, running a handful of casino and betting sites rather than a sprawling network.
Licensing and how the sites reach Australia
The group holds its licences in Curacao, and that regime has shifted a lot lately. The LOK reform, passed in December 2024, scrapped the old master-and-sublicence system. Every operator now needs a direct licence from the new Curacao Gaming Authority, listed on a public register. Curacao runs a lighter touch than the UK or Malta, so the checks are less strict. That is worth keeping in mind before you sign up. Australia does not license this type of site at all. The Interactive Gambling Act restricts local operators rather than players. That is why Curacao brands are how most Australians end up playing online pokies and table games.
Games and software
These sites lean towards a big, crypto-friendly casino floor rather than a curated shortlist. Libraries stretch to several thousand titles and pull from studios such as Evolution for live dealer tables, Pragmatic Play and Play’n GO for pokies, and NetEnt. A sportsbook usually shares the same account as the casino, so you do not register twice. Crypto deposits run right across the brands, which suits players who like to bank that way.
What it means for Australian players
Two things matter most here: the offshore licence and the banking. Because the sites operate from Curacao, you are betting with a company outside Australian oversight, and standard identity checks apply before a withdrawal clears. Weigh a broad game range and crypto payments against a lighter-touch regulator and no local licensing, then decide if the trade suits you. The casinos listed below are similar offshore options if you want to compare a few first.
Who is behind the OnyxioN B.V. casinos?
They are run by a company that registered in Curacao in 2019 as OnyxioN B.V. In 2022 it was renamed Santeda International B.V., and its Cyprus operating arm, Onyxion Development Limited, became Santeda International Limited.
Is OnyxioN B.V. the same company as Santeda International?
Yes. OnyxioN B.V. and its Cyprus subsidiary were both renamed to Santeda International in 2022, so the two names point to the same group.
What licence do the OnyxioN casinos hold?
The group is licensed in Curacao. Since the LOK reform of December 2024, Curacao operators need a direct licence from the Curacao Gaming Authority rather than an old-style sublicence.
Can Australians use OnyxioN B.V. casinos?
The operator is based offshore in Curacao and is not licensed in Australia. The Interactive Gambling Act restricts operators rather than players, so Australians commonly use offshore sites like these.
What games do the group's casinos offer?
Large libraries of pokies, table games and live dealer titles from studios such as Evolution, Pragmatic Play and Play'n GO, plus a sportsbook, with cryptocurrency deposits widely accepted.
