Challenges we ran into

Implementing On-Chain Randomness
Ensuring fair play in the casino games was critical, and implementing on-chain randomness was a significant challenge. We utilized Aptos randomness module: aptos_framework::randomness to achieve provably fair outcomes for our games. This required a deep understanding of the randomness mechanisms and careful integration into our smart contracts. All though the docs provided by the Aptos were super useful.

Wallet Integration and User Experience
Integrating Pedra and Okto's embedded wallet technology presented its own set of challenges. We had to ensure that the wallet packages and versions were compatible to our needs. We worked closely with couple of friends who were previously part of Aptos Winter School IIT Bombay for Pedra integration and aptos github to resolve integration issues and optimize the wallet's functionality for our needs.

Ensuring Cross-Chain Compatibility
One of the major challenges we faced was ensuring smooth cross-chain compatibility. Integrating multiple blockchains and facilitating seamless asset transfers between them required meticulous planning and extensive testing.

Security and Testing
Ensuring the security of our platform was a top priority, but it also posed significant challenges. We conducted extensive smart contract testing via test scripts and code reviews to identify and fix potential vulnerabilities. Implementing robust security measures for user funds and encryption of on-chain data was crucial.

User Onboarding
Simplifying the onboarding process for new users was another challenge. Many users are not familiar with blockchain technology and can find it intimidating. We focused on creating a user-friendly interface and streamlined the onboarding process with Aptos Pedra and Okto easy-to-use wallet solution. This involved iterative design and testing to ensure a smoother user experience.
