Cryptopia

Cryptopia is a cross-chain web3 social platform. Only verified project owner can post here, so there are less spams. Users can only comment or participate in an event or airdrop. Project owners can post announcements, airdrops, events and jobs. Users can follow the projects they are interested in.

Users can also join project's own group chat, but they have to hold that project's tokens to be able to enter or talk.

First of all, Cryptopia use @Filecoin web3.storage to store all the posts and projects' information. After a post is created, the cid returned by web3.storage is stored in contract and an event is emitted.

@The Graph Subgraph will collect the post or follow events, and frontend use graphql to query these data.

@Sismo helps Cryptopia to verify project owner. We created a group and only if the project owner fits the criteria, the project can be verified.

Cryptopia uses @Axelar and @Wormhole to send cross-chain messages to broadcast these projects are verified. so projects only need to be verified on one network.

Cryptopia is deployed on testnets of Scroll, Mantle, Arbitrum and Polygon
