Independent Fair Draw
Verification for Every Competition
Give your players cryptographic proof that every draw you run is fair, transparent, and tamper-free. Trusted by operators who take fairness seriously.
Why Operators Choose CAAS
Compliance isn't just a checkbox. It's your competitive advantage.
Fairness Your Players Can See
Every draw produces a public audit page backed by cryptographic hash chaining. It proves your result wasn’t manipulated, altered, or generated after the fact.
Tamper-Evident Integrity Chain
Each draw is immutably linked to the previous one. If anything changes — even a single field — the entire chain breaks, making tampering instantly detectable.
Aligned with DCMS Principles
Built around fairness, auditability, and open verification — helping operators stay ahead of regulatory direction and demonstrate best practice.
How It Works
Four simple steps to absolute transparency. Integrate once, run forever.
Register Your Competition
Send basic competition data via API or seamless platform integration.
Submit Entries
Paid and free entries are logged securely with full integrity tracking.
Trigger the Draw
CAAS generates a secure seed, randomises the entry pool, and selects a winner.
Share the Public Audit Page
Your customers verify fairness instantly — no explanations required.
Tamper-Proof Transparency,
Secured by Cryptography
Every draw event becomes part of the CAAS Fairness Chain — a global, append-only timeline of competition results.
Each event contains the hash of the previous event, forming an unbreakable chain of trust. This ensures:
- Operators cannot alter past draws
- Mistakes cannot be hidden
- All draw data remains verifiable forever

If your customers ever question fairness, CAAS protects your reputation and increases trust instantly.
