### Payment System

The payment system is an entry point that supports users of the PsuB platform to easily use the payment service. PsuB wallet, SuBPay, mobile app, and operation management web have been developed to connect sellers and consumers through point payment systems and applications.



### Utility System

The utility system is designed for PsuB platform users to utilize PsuB tokens. Real estate, game NFT, etc. will be issued and traded in the NFT market PsuB Box, where PsuB will be used as a payment method for payments and fees along with Ethereum and Klaytn. It will also launch virtual asset wallet insurance to meet users' needs for asset safety.



### Technical Support

The PsuB ecosystem has a multi-chain structure that utilizes multiple side chains in one blockchain for efficient operation and excellent security. This is to deal with the high cost, which is pointed out as a disadvantage of the blockchain, at a low cost through the side chain, and to ensure stable data consistency between the chains through standard protocols. All information and terms and conditions on issuance and utilization and operation of major assets such as token utilization, payment system, data collection system, user management system, merchant management, payment method management, and settlement management are distributed and stored in the blockchain. Also, administrator pages to manage it are implemented, and are designed to facilitate integrated management systems, including limiting access to each feature, so users can take advantage of them. It is also designed to facilitate cross-expansion with other services by complying with standard protocols. In addition, the multi-chain structure enables fluid blockchain operation, so it is less binding for communities and ecosystems, and it can be expected to have effects such as reduced fees and increased speed.



### Legal Review

PsuB has minimized the possibility of legal disputes that may arise when issuing SuB Points, and will fully comply with and implement the current laws during operation. In addition, we will strictly follow the personal information protection policy when operating PsuB Wallet, and we will prepare a procedure to comply with the guidelines for preventing money laundering when SuB Point is settled.
