“The Streamr Network offers an ideal opportunity to build decentralized communication andsocialmediaapplications.FortheWeb3communitytomigratefromusingWeb2messagingplatforms, they need a protocol that’s fast and serverless. We hope thechat.app provides atangible inspiration for builders to explore the possibilities of truly permissionless real-timecommunicationswithStreamr.” Chat rooms come in three types—public, private and token gated. Token gated rooms allowusers to configure an access control policy to check users hold a chosen token, or a certainamountoftokensintheirwallet,beforegrantingthemaccess.Privateroomsrestrictaccesstochosen users. Public rooms are viewable by anyone. Messages in all room types are securedby end to end encryption and allow users to communicate without any intermediaries.

The Beta version of thechat.app is built to work best as a desktop browser application withusers connecting via their wallets, including MetaMask, Coinbase Wallet, or WalletConnect.Creating rooms and invites are on-chain transactions, while messages in chats arecryptographically signed and delivered over the Streamr Network.
