Pearl conducts custom classification and management of information at the receiving end and sending end respectively, which greatly solves the problem of message overload question. The platform mainly consists of three core parts, a mobile information receiving application, so that users can accurately control the type of notification; information sending Dashboard, where community managers can set and send message notifications after verifying their identities on the chain; Centralized inter-wallet communication protocol YAMP (Yet Another Message Protocol) to ensure the security and verifiability of information transmission.

The first is the mobile app. After binding the wallet, we can see the NFT community we are in. Click on any NFT community to enter the message management page, where users can choose the type of messages they want to receive. For each NFT item, users can make individual personalized receiving settings.

Next is the information sending page. After connecting the wallet, the community administrator can edit the message name, type and content, and send the secure message through the YAMP protocol after completing the wallet signature. Users receive outgoing messages on Pearl mobile's "Inbox" page.
