PickUp is a landed social metaverse system based on DID protocol multi-chain deployment. In the PickUp metaverse, the ideas of Gamefi, Socialfi, and NFTFi are integrated and combined in practice through the technology of blockchain to build their own exclusive PickUp social graph. Users can create their own DIDs in the PickUp metaverse, which represent different values through different DID digits, and thus build their own exclusive social graph network.
