Fair Play Guarantee
Transparency, Integrity, and Provably Fair Gaming
At cromafun, fairness isn't just a promise—it's a guarantee backed by cryptographic proof and blockchain transparency. Every game outcome is verifiable, ensuring that neither the platform nor players can manipulate results. This page explains our commitment to fair play and how you can verify it yourself.
1. Our Fair Play Commitment
cromafun operates on three core principles of fairness:
Cryptographic Security
All random outcomes use industry-standard cryptographic algorithms that cannot be predicted or manipulated.
Complete Transparency
Every game round's outcome can be independently verified using publicly available data and tools.
Blockchain Integrity
All transactions are recorded on the Solana blockchain, providing an immutable audit trail.
2. How Our Games Ensure Fairness
cromafun uses a hybrid approach to ensure both performance and verifiability:
Off-Chain Games (Provably Fair)
Games: Color Clash, Color Predict, Color Wheel, Color Tower
Cryptographically Secure Random Number Generation (CSPRNG)
We use crypto.randomBytes, a cryptographically secure pseudo-random number generator that produces unpredictable outcomes based on:
- Server Seed: A secret value known only to our secure server
- Client Seed: Your wallet address contributes to randomness
- Nonce: A unique counter that increments with each game
Verification Process
Before each round, a hash of the server seed is published
After the round, the actual server seed is revealed
You can verify the hash matches the revealed seed
Combine server seed + client seed + nonce to reproduce the exact outcome
On-Chain Games (Fully Transparent)
Game: Crypto Race
Real-Time External Data
Crypto Race uses live cryptocurrency price data from CoinGecko API, ensuring outcomes are based on real market movements that cannot be manipulated by cromafun.
How It Works
Starting prices for BTC, ETH, and SOL are fetched and recorded at round start
After 20 seconds, ending prices are fetched from the same source
Percentage gain is calculated: (End Price - Start Price) / Start Price × 100
The cryptocurrency with the highest gain wins
You can verify the prices independently on CoinGecko
3. Platform Fees & House Edge
We believe in transparent pricing. Here's exactly what we charge:
Platform Fee: 2.5%
This is significantly lower than traditional casinos (5-10%) and most crypto platforms (3-5%).
Example:
Total pot: 100 CT
Platform fee: 2.5 CT
Player winnings: 97.5 CT
Fee Distribution
Our 2.5% fee is distributed to benefit the entire ecosystem:

5. How to Verify Game Outcomes
We encourage all players to verify game fairness. Here's how:
Step 1: Access Your Game History
Navigate to your profile dashboard and click on "Game History" to view all past rounds.
Step 2: View Round Details
Click on any round to see detailed information including server seed hash, client seed, nonce, and final outcome.
Step 3: Verify the Hash
Use our built-in verification tool or any SHA-256 calculator to confirm the server seed matches the pre-published hash.
Step 4: Reproduce the Outcome
Use our verification script (available on GitHub) to combine the seeds and nonce to independently calculate the outcome.
GitHub Repository: All verification scripts are open-source and available at github.com/cromafun/verification-tools
6. Security Audits & Third-Party Verification
cromafun undergoes regular security audits to ensure platform integrity:
Smart Contract Audits
All smart contracts are audited by reputable firms (CertiK, Halborn) before deployment
RNG Certification
Our random number generation is certified to meet industry standards
Penetration Testing
Regular security testing to identify and fix vulnerabilities
Blockchain Transparency
All transactions are permanently recorded on Solana and publicly viewable
7. Anti-Cheating Measures
We employ multiple systems to detect and prevent unfair play:
- Automated monitoring for suspicious betting patterns
- Multi-account detection and prevention
- Bot detection and rate limiting
- Collusion detection algorithms
- Manual review of high-value transactions
- IP address and device fingerprinting
- Wallet address blacklisting for known bad actors
⚠️ Cheating Consequences
Accounts found to be cheating, colluding, or using bots will be immediately banned. All winnings will be forfeited and returned to affected players.
8. Dispute Resolution
If you believe a game outcome was unfair:
Verify the outcome yourself using our verification tools
If you still have concerns, contact support with the specific Round ID
Our team will investigate and respond within 24 hours
