The token protocol of existing online casinos is centralized, making it difficult to transparently prove users' asset ownership. Additionally, due to the nature of casinos and the instability and risks associated with services, it becomes challenging to recover users' assets properly if the site becomes unstable or difficult to operate. To address these issues, we have implemented a hybrid decentralized approach called the S2K L2 (Split Security Key Layer2) system. The S2K L2 system checks the user's cryptocurrency holdings within the wallet daily. In case of issues with the casino service, users can recover their wallets through the 'WALLET RECOVERY' service using the security key provided at the time of registration. This ensures that users can securely retrieve their deposited cryptocurrencies at any time, even if the casino server experiences downtime. By addressing the risks associated with centralized exchanges like FTX, we aim to provide users with transparency and stability, differentiating our service from others in the market. Through this initiative, we aspire to create new opportunities in a market expected to see significant growth and establish a notable presence in the global fiat (token) based casino market.
