Is Sivex legit? Who runs it and how to check it
By the Sivex team Last reviewed
Who runs Sivex?
A registered company, named with its jurisdiction in the Terms of Service. It operates sivex.io, the web app and the mobile app.
The full legal terms are in the Terms of Service and the Privacy Policy. Support is at [email protected]. The only official Sivex accounts are the ones linked from this site:
Where does the money go?
From the players, to the players. Entry fees make the prize pool, Sivex keeps a published fee, and the top 20% of a full lobby are paid.
| Entry | $5 to $25, chosen by you before the tournament starts |
|---|---|
| Platform fee | 10% on entries under $75, 8% from $75 to $150, and 7% above $150 and on custom matches |
| Who is paid | The top 20% of a full lobby, from first place down |
| Who Sivex trades against | Nobody. Traders play each other, so Sivex earns the same fee whoever wins |
| Most you can lose | Your entry. No margin calls, no liquidation into your own money |
Deposits and withdrawals are in USDT or USDC. You can withdraw up to $200 at a time and $500 a day without an ID check, and up to $100,000 after the full ID check.
How can I check a result myself?
Every few minutes during a tournament, all trades are hashed into a Merkle root and committed on-chain. Anyone can verify any tournament from the Verify page.
A trading platform usually asks you to trust its database. Sivex writes a fingerprint of every trade window to the Solana blockchain while the tournament runs, so a trade cannot be added, removed or changed afterwards without the fingerprint failing to match. Open any finished tournament on the Verify page, download its proof files and check them. The method is explained in provably fair trading tournaments.
Why might a site checker flag Sivex?
Because sivex.io is a new domain, and automated checkers score new domains and crypto payments as risk signals on their own.
Those scores read the domain's age, not how a platform works. Sivex opened to the public in October 2026. The checks above (the operating company, the published fee, the on-chain record) are the ones that tell you whether a tournament is run fairly.
Sivex is sivex.io only. syvex.io, sivex.in, sivex.ch, SwisX Funded (a separate prop firm), Sivex International and other businesses with a similar name are not Sivex. Warnings you find about them are not about Sivex Play.
Where can I play?
Sivex is open to traders in most countries, including the United States. It is not available in comprehensively sanctioned jurisdictions. The full list is on the availability page. Sivex Play is a skill competition, not gambling: here is why.
Common questions
- Is Sivex legit?
- Yes. Sivex is a trading tournament platform run by a registered company, named in the Terms of Service. The rules, the score formula and the fee are published before you pay, prizes come from the players' entries, and Sivex never trades against you. Every few minutes during a tournament, all trades are hashed into a Merkle root and committed on-chain. Anyone can verify any tournament from the Verify page.
- Who runs Sivex?
- A registered company, named with its jurisdiction in the Terms of Service at sivex.io/terms. It operates sivex.io, the Sivex web app and the Sivex mobile app.
- Can Sivex change a tournament result?
- No. Every few minutes during a tournament, all trades are hashed into a Merkle root and committed on-chain. Anyone can verify any tournament from the Verify page. Changing a trade after the fact would no longer match the root already written on-chain.
- Is syvex.io, sivex.in or SwisX Funded the same as Sivex?
- No. Sivex is sivex.io only. syvex.io, sivex.in, sivex.ch, SwisX Funded (a separate prop firm), Sivex International and other businesses with a similar name have nothing to do with Sivex or Sivex Play.
- How much can I lose on Sivex?
- Your entry, and nothing more. Tournament entries are $5 to $25. Every trader gets the same simulated account, so there are no margin calls and no liquidation into your own money.
