Our Process

How We Built Bera Royal

A transparent, methodical approach that took Bera Royal from concept to a fully functional blockchain gaming platform in just 8 weeks.

Our Approach

“Building blockchain applications isn’t just about writing smart contracts—it’s about creating secure, scalable systems that users trust with their money. Our process combines rigorous security practices with agile development, ensuring every line of code is audited and every feature is battle-tested before launch.”

Discovery & Planning

1 Week • Foundation Phase

We started with deep-dive sessions to understand the vision, define user flows, and map out technical requirements for the prediction gaming platform.

  • Requirement analysis and user story mapping
  • System architecture and database schema design
  • Tech stack selection (Berachain, Deno, Next.js)
  • Security threat modeling and risk assessment

Smart Contract Development

3 Weeks • Core Infrastructure

Built bulletproof smart contracts on Berachain with optimized gas usage, secure bet handling, and automated winner distribution logic.

  • Solidity contracts with OpenZeppelin libraries
  • $HONEY token integration and approval flows
  • Oracle integration for BERA/BTC price feeds
  • Gas optimization and contract testing on testnet

Full-Stack Integration

2 Weeks • Frontend & Backend

Developed the complete application layer connecting the blockchain with an intuitive user interface and real-time game state management.

  • Deno backend with WebSocket for live updates
  • Next.js frontend with MetaMask integration
  • Real-time price tracking and bet management
  • Responsive UI with TailwindCSS styling

Testing & Security Audits

1 Week • Quality Assurance

Comprehensive testing phase including smart contract audits, penetration testing, and stress testing to ensure rock-solid security and performance.

  • Smart contract security audit with automated tools
  • Load testing with simulated 1000+ concurrent users
  • Penetration testing for anti-cheat mechanisms
  • Cross-browser and mobile compatibility testing

Overcoming Obstacles

Complex Challenges, Elegant Solutions

Building a decentralized prediction platform required solving unique technical challenges. Here’s how CodeHazel’s expertise turned obstacles into competitive advantages.

Challenge #1

Ensuring Fair Gameplay On-Chain

Blockchain transparency creates a unique problem: all data is public. Users could potentially monitor pending transactions to gain unfair advantages before price predictions are locked.

  • Mempool visibility allows malicious actors to see bets before confirmation
  • Front-running attacks could manipulate bet timing for unfair advantage
  • Price oracle manipulation could influence game outcomes
  • Multiple accounts from single user could skew prize distribution
Our Solution

Multi-Layer Anti-Cheat System

Implemented a comprehensive security architecture combining time-locked commitments, decentralized price oracles, and cryptographic verification to eliminate manipulation vectors.

  • Commit-reveal scheme: users submit encrypted predictions that can’t be changed after timestamp
  • Multiple oracle integration with consensus mechanism prevents single-source manipulation
  • Bet cutoff window enforced at smart contract level before price resolution
  • On-chain transaction fingerprinting to detect and flag suspicious betting patterns

Challenge #2

High Gas Costs for Multi-User Games

With multiple users placing bets and automatic winner distribution, gas costs could quickly become prohibitive, making the game economically unviable for smaller bets.

  • Individual winner payouts in loops caused excessive gas consumption
  • Storage operations for bet history and user stats inflated transaction costs
  • Redundant oracle calls and price checks wasted blockchain resources
  • Complex winner calculation logic increased computational overhead
Our Solution

Advanced Gas Optimization Techniques

Refactored smart contracts using assembly optimizations, batch processing, and efficient data structures to reduce gas costs by 60% while maintaining functionality.

  • Batch winner payouts using merkle tree distribution instead of individual loops
  • Packed storage structs to fit multiple variables in single slots (uint256 optimization)
  • Cached oracle prices with time-based refresh to minimize external calls
  • Assembly-level optimizations for critical calculation paths
Gas Optimization Example
Solidity
// Before: ~280k gas
for (uint i = 0; i < winners.length; i++) {
  payable(winners[i]).transfer(prize);
}

// After: ~95k gas (66% reduction)
bytes32 merkleRoot = calculateRoot(winners);
// Users claim via merkle proof
60%

Challenge #3

Real-Time State Synchronization

Blockchain confirmation times (2-12 seconds) created UX challenges. Users needed instant feedback while maintaining accuracy with on-chain state.

  • Block confirmation delays caused perceived lag in bet placement and results
  • Price feed updates and blockchain state often out of sync causing confusion
  • Multiple users betting simultaneously needed real-time pool updates
  • Chain reorganizations could invalidate pending transactions creating inconsistent UI state
Our Solution

Hybrid State Management Architecture

Built a sophisticated hybrid system combining optimistic UI updates, WebSocket event streaming, and blockchain event monitoring to deliver instant UX without sacrificing accuracy.

  • Optimistic UI updates show instant feedback, then reconcile with blockchain confirmation
  • WebSocket server pushes real-time events to all connected clients for live prize pool updates
  • Event listeners on smart contracts emit updates that backend relays to frontend instantly
  • Fallback polling mechanism ensures state consistency even with WebSocket failures

  reconcileState();
});
