Verified trading automation
The seller’s screenshot isn’t evidence. So we stopped accepting it.
Every bot and Expert Advisor here is checked by us before it can be listed — and the certificate says what we didn’t check, too. Every listing carries that certificate, with its date and its limits.
The problem
This market runs on the seller’s word.
The seller wrote the description. The seller ran the test. The seller picked the screenshot.
The archive lands in your inbox. That is where your reading starts.
Some tools want full trading access first. Before they do anything at all.
The cost: you carry the consequences of a product you were never allowed to open.
Same forum thread. Same claims. Same wall of doubt.
Your own numbers are not evidence. Buyers already know that.
Licence keys. DRM. Checkout. Payouts. Months of work that isn’t your product.
The cost: the work is finished and it still has nowhere to go.
I bought bots off forums for two years and read the code afterwards, when it was already running my account. Viroan is the place I wanted to buy from back then.
What the check catches
Three of the last ten submissions
didn’t make it.
Anonymised, straight from the reports:
Not one of them was visible in a screenshot, and all three would have sold. The reports are anonymised and readable — see what they were rejected for.
The check
One standard. Six steps.
Every certified listing carries a certificate from a check we ran, not a claim the seller wrote. You submit the build. We read the source, run it against data and periods you didn’t choose, break it on purpose — then seal and publish what survived.
- 01
Formal check
The submission, the creator’s identity and the declared scope.
- 02
Static scan
The source code is scanned against the declaration.
- 03
Backtest
On market data we hold, not on a period the creator picked.
- 04
Robustness and Monte-Carlo
How the result holds up when conditions change.
- 05
Scoring
Against the limits the creator declared.
- 06
A person decides
A person at Viroan makes the final decision.
Non-custodial: Viroan does not receive a buyer’s exchange or broker keys, does not hold funds, and does not place orders. You buy a licence and the software runs on your side.
Each stage in full, what the certificate states and what it never states: how the check works.
Where this stands
Viroan sp. z o.o., operating from Kraków, Poland, in the EU/EEA. Not authorised or supervised by any competent authority.
Exchange and broker credentials stay with the buyer. We hold nothing.
Verified by Viroan, independently of the product’s creator, before a certified product is listed.
The certificate
What every listing carries.
Not a badge. The record of the check itself — public, dated, and sitting next to the buy button rather than behind it. One object, and it is the whole product.

The certificate above is an illustration — the identifier, score and hash are not a real record. Every real certificate names its own limits the same way. A check that claimed to cover everything would be worth nothing — and nothing here is a forecast or advice.
The business model
We are paid on a sale, not on a verdict.
€100 list price · €85 to the creator · €115 from the buyer before VAT · €30 ours
We are paid when a licence sells and not for a verdict, which is the only arrangement under which a check is worth reading. The numbers, worked through →
How it works
Three steps, whichever side you’re on.
Open the catalogue
Every listing and every certificate is readable without an account.
Buy the licence
A licence for a term, at the price on the listing. The certificate sits next to the buy button, not behind it.
Connect it and run it
Install on your own exchange or broker account. Your keys stay with you. Stopping is your decision alone.
Submit the build
Upload the build with its manifest and declared scope. Applying is free.
Pass the check
Six steps on our side. You get the report, and the certificate publishes with the listing.
Set a price and get paid
Licensing, checkout, invoices, VAT and payouts run on our side. You set the list price and receive 85% of it per licence.
FAQ
Before you buy, or before you publish.
01Who checks the software?
We do, before publication, and the record is public. We read the source and run the build against data and periods the creator didn’t choose. The seller’s own report is not part of it.
02Do you ever hold my funds or my keys?
No. Viroan sells software licences. Exchange and broker credentials stay with you, the software runs on your side, and we place no orders on anyone’s behalf.
03What does a certificate actually cover?
The stages cleared, the data and period used, the delivery mode, the seal hash of the build and the date — plus an explicit statement of what the check did not cover.
04Can I keep my code private?
Yes. Ship the build compiled and licence-locked and the source stays with you — we read it during the check, the buyer runs the sealed build. Publishing the source is a per-version choice, not a condition.
05What does it cost a creator?
Nothing until something sells: applying, the check and the listing are free, pass or fail, and there is no monthly fee. On a sale the fee is split across both sides — 15% out of your list price and 15% added to what the buyer pays — so a €100 listing pays you €85 and costs the buyer €115, shown to them as one total with the VAT of their country included. The arithmetic, worked through →
06What happens when a product is updated?
The new version re-enters the pipeline. Until it clears, buyers keep running the build that was sealed — an update never reaches anyone unchecked.
