Crazd

Overview

CRAZD is a high-performance, on-chain multiplayer betting platform deployed on Mantle Network. The platform delivers sub-second game state synchronization, cryptographically verifiable outcomes, and instant settlement through smart contract integration.

Two flagship game modes are currently live:

• Crash: Real-time multiplier game with continuous rounds

• Candleflip: 8-second binary prediction markets

Problem Statement

Traditional online betting platforms suffer from fundamental trust and transparency issues:

• Centralized outcome generation with no external verifiability

• Delayed withdrawals requiring manual approval processes

• Opaque server-side logic susceptible to post-bet manipulation

• KYC requirements creating friction and privacy concerns

• Custodial fund management introducing counterparty risk

Solution

CRAZD implements a trustless betting infrastructure with the following properties:

• Pre-committed Outcomes - Game results are cryptographically locked via SHA-256 hashing before any bets are accepted

• On-chain Settlement - All payouts execute atomically through verified smart contracts

• Non-custodial Architecture - Player funds remain in user wallets until bet placement; winnings are returned directly

• Permissionless Access - Wallet-based authentication only; no registration, KYC, or personal data collection

• Public Verifiability - Server seeds are revealed post-game, enabling independent outcome reconstruction

Technical Architecture

Real-time Infrastructure

• WebSocket-based state synchronization at 60fps

• Sub-200ms latency for game state updates

• Horizontal scaling support for concurrent game rooms

• Persistent connection management with automatic reconnection

Blockchain Integration

• Smart contract deployment on Mantle Sepolia Testnet

• Contract Address: 0x80Fc067cDDCDE4a78199a7A6751F2f629654b93A

• Gasless meta-transactions for improved UX (planned)

• Direct contract calls for bet placement and payout settlement

Provably Fair System

• Server seed generation using cryptographically secure randomness

• SHA-256 hash commitment published before betting window opens

• Seed revelation upon game completion for public verification

• Deterministic outcome derivation from seed + game parameters

Game Modes

Crash

• Multiplier begins at 1.00x and increases exponentially

• Players cash out at any point to lock in current multiplier

• Game terminates at predetermined crash point (unknown to players)

• Round duration: 10 seconds to 2 minutes

• Real-time visibility of all active player positions

• Live cashout and rug notifications broadcast to all participants

  

Candleflip

• Binary outcome prediction (Bullish/Bearish)

• 40-tick price simulation over 8-second duration

• 2x payout on correct prediction, full loss on incorrect

• Parallel room support for simultaneous position management

• Independent seed per room ensuring outcome isolation

  

Platform Features

• Multiplayer Experience - Live player activity feeds, real-time bet tracking

• Social Layer - Integrated chat system with message persistence

• Competitive Rankings - Global leaderboard sorted by cumulative profit

• Responsive Design - Full mobile and desktop compatibility

• Wallet Integration - Privy-powered authentication supporting MetaMask, WalletConnect, and embedded wallets

Constraints & Limitations

• Currently deployed on Mantle Sepolia Testnet only

• Maximum bet limits enforced per round

• Rate limiting on consecutive bet placement

• WebSocket connection required for real-time features

• Smart contract balance constraints affect maximum payout capacity

Roadmap

• Public verification API for programmatic game auditing

• Mainnet deployment following security audit completion

• Additional game modes under development

• Enhanced analytics and player statistics dashboard

• Tournament and multiplayer competition features
