+Chataverse is an NFT-gated messaging app that enables NFT holders and creators to communicate, socialize, and govern transparently and crypto-natively. Aside from NFT's financial incentive, another main reason for a person to purchase an NFT is to access and engage in its community. While most of these communities are built on Discord, the platform itself has problems such as high vulnerability to being hacked and spammed, bombarded channels that can be irrelevant, and countless bots/plug-ins that are complicated. In order to tackle these problems, Chataverse provides the following solutions: - NFT-gated group chats to prevent scams and spam (100% holders). - Freedom to create and join topic-based messaging groups within an NFT community. (ex. Azuki @ San Francisco, Bored Ape Basketball Club). - Forum-style groups for large communities that allow NFT holders to post, comment, and react. - Built-in NFT community management tools that include voting, airdrops, and event proposals. - On-chain "Chataccount" that can aggregate a user's multiple wallets across multiple chains to avoid the inconvenience of switching between wallets.
