Description
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 AI 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 Flow VRF 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 Flow VRF 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.
