In the common centralized platform, digital and online games were prone to hacking and cyber-attacks from the beginning of time. Storing digital gaming assets on a blockchain would enhance the security for a player who has worked hard to collect them. The in-game purchases are recorded thoroughly on the digital ledger. We significantly increase transparency, maintain the game balance, and prevent the theft of ownership. Since the digital gaming assets are on-chain, the in-game assets cannot be replicated or destroyed as it is unique. For a users on-chain transaction, the smart contract design guarantees the atomicity of transaction settlement, that is, either the transaction conditions are met to complete the settlement, or the transaction fails, and the users assets are always kept in the wallet, under the users control. We support all major Web3 wallets, which will bring not only convenience but also security. It was identified as a huge challenge to store all large data on the blockchain and not efficient. We keep those off-chain data secured by indexing them with a hash function and storing the blockchains indexed hash value that cannot be modified. In many projects, security-related tasks were only tackled at the very end of the software development lifecycle. Right before its going to be deployed, a security team, or an auditing team, sometimes even externally hired only for a short period of time, would step in, do some review, and generate some reports and improvement plans. Instead of a security audit as a silo at the end, we do it on the fly. By shifting left, security practices and testing are performed earlier in the development lifecycle, rather than at the end, which allows us to discover security issues earlier and fix them immediately. ...
