APT-Casino-0g

A couple of days back, I was was on etherscan exploring some transactions and saw an advertisement of https://stake.com/ which was giving 200% bonus on first deposit, I deposited 120 USDT into stake.com they gave 360 USDT as total balance in their controlled custodial wallet and when I started playing casino games I was shocked to see that I was only able to play with $1 per game and was unable to increase the betting amount beyond $1 coz and when I tried to explore and play other games on the platform the issue was persisting, I reached the customer support and got to know that this platform has cheated him under the name of wager limits as I was using the bonus scheme of 200%.

When I asked the customer support to withdraw money they showed a rule list of wager limit, which said that if I wanted to withdraw the deposited amount, then I have to play $12,300 worth of gameplay and this was a big shock for me, as I was explained a maths logic by their live support. Thereby, In the hope of getting the deposited money back, I played the different games of stake.com like roulette, mines, spin wheel, etc, the entire night and lost all the money.

I was very annoyed of that's how APT-Casino was born, which is a combination of GameFi and DeFi all in one platform where new web3 users can play games, perform gambling, but have a safe, secure, transparent platform that does not scam any of their users. Also, I wanted to address common issues in traditional gambling platforms.

🧩 Problems

The traditional online gambling industry is plagued by several issues, including:

• Unfair Game Outcomes: 99% of platforms manipulate game results, leading to unfair play.

• High Fees: Users face exorbitant fees for deposits, withdrawals, and gameplay.

• Restrictive Withdrawal Policies: Withdrawal limits and conditions often prevent users from accessing their funds.

• Bonus Drawbacks: Misleading bonus schemes trap users with unrealistic wagering requirements.

• Lack of True Asset Ownership: Centralised platforms retain control over user assets, limiting their freedom and security.

• User Adoption of Web2 Users: Bringing users to web3 and complexity of using wallet first time is kinda difficult for web2 users.

• No Social Layer: No live streaming, no community chat, no collaborative experience.

💡 Solution

APT-Casino addresses these problems by offering:

• Provably Fair Gaming: Utilising the Pyth Entropy on-chain randomness module, my platform ensures all game outcomes are 100% transparent and verifiably fair.

• Flexible Withdrawal Policies: Providing users with unrestricted access to their funds.

• Transparent Bonus Schemes: Clear and clean bonus terms without hidden traps.

• True Asset Ownership: Decentralised asset management ensures users have full control over their assets.

• Fully Gasless and Zero Requirement of Confirming Transactions: Users do not require to pay gas fees. It's paid by our treasury address to approve a single transaction — we do it all, they can just play as if they are playing in their web2 platforms.

• Live Streaming Integration: Built with Livepeer, enabling real-time game streams, tournaments, and live dealer interaction.

• On-Chain Chat: Supabase + Socket.IO + wallet-signed messages ensure verifiable, real-time communication between players.

• ROI Share Links: Every withdrawal (profit or loss) generates a shareable proof-link that renders a dynamic card (similar to Binance Futures PnL cards) when posted on X.

⚙️ Key Features

• On-Chain Randomness: Utilizing Pyth Entropy on-chain randomness module to ensure provably fair game outcomes.

• Decentralized Asset Management: Users retain full control over their funds through secure and transparent blockchain transactions.

• User-Friendly Interface: An intuitive and secure interface for managing funds, placing bets, and interacting with games.

• Diverse Game Selection: A variety of fully on-chain games, including roulette, mines, plinko, and spin wheel. As a (POC) Proof of Concept, developed fully on-chain 4 games but similar model can be applied to introduce the new casino games to the platform.

• Fully Gasless and Zero Requirement of Confirming Transactions: Users do not require to pay gas fees. It's paid by our treasury address to approve a single transaction — we do it all, they can just play as if they are playing in their web2 platforms.

• Real-Time Updates: Live game state and balance updates.

• Event System: Comprehensive event tracking for all game actions.

• Social Layer: Live streaming, on-chain chat, and NFT-based player profiles.

• Dual 0G networks: Deposits and withdrawals use the 0G chain your wallet is connected to (Mainnet or Galileo Testnet); withdrawals are sent on the same chainId.

🧩 Architecture

• Frontend: Next.js (App Router), React 18, Tailwind, MUI, Three.js

• Wallet/Chain: wagmi + RainbowKit

• Randomness: Pyth Entropy (consumer contract + callback flow)

• State: Redux Toolkit + React Query

• Social: Livepeer for streaming, Supabase for real-time chat

• Data: PostgreSQL + Redis

• Data Availability: 0G DA (game history, audit trails) - Integration Guide

• Storage: 0G Storage (game assets, user profiles, backups) - Integration Guide

🔗 Networks

• Gaming / App Network: 0G Mainnet (chain ID 16661) and 0G Galileo Testnet (chain ID 16602) — switch in MetaMask; deposits and withdrawals follow your connected chain

• Entropy / RNG: Arbitrum Sepolia (Pyth Entropy) — treasury wallet needs Sepolia ETH for entropy fees

• Data Availability: 0G DA (for game history and audit trails)

🎮 Games

• Roulette: European layout, batch betting

• Mines: Pattern presets, variable risk

• Plinko: Physics-based ball path, auto-bet modes

• Wheel: Multiple segments with adjustable volatility
