Towns Protocol is a protocol for building decentralized real-time messaging apps. It consists of an EVM-compatible L2 chain, decentralized off-chain stream nodes, and smart contracts that are deployed on Base. Towns Protocol allows people to create programmable communication use cases, referred to as “Spaces,” in a permissionless manner. These Spaces are ownable, feature on-chain subscriptions (”Memberships”), extendable reputation system, and end-to-end message encryption.

XMTP is a fundamental new building block for the next iteration of the web—a permissionless, crypto-native communication protocol that connects communities, creators, protocols, applications, and users. XMTP will enable communication between existing crypto wallets through its own independent protocol and decentralized network.

Converse is a Web3 messaging app built with XMTP that allows user connect with any wallet and Encrypted end to end & decentralized converse.

dm3 protocol is a web3 messaging protocol that utilizes a general registry for public keys (for encryption and signature verification) and delivery information based on ENS (e.g., ENS text record eth.dm3.profile). It also uses decentralized delivery service nodes. Intended to work as an interoperability layer, DM3 enables various dApps, protocols, and services to exchange messages in a standardized way.

Boto is creating a platform for creating no-code bots in the crypto space. Users can use Boto to track specific NFTs, governance proposals, portfolios, and wallet and on-chain activity.

DMTP is a protocol that allows users to exchange messages on a wallet address basis. Users can send and receive messages to each other, and Dapps can send notifications and messages to users. The great thing is that DMTP can support all chains, so for example user can send messages to friends in different chains. Furthermore, the implementation of Communication Rewards and Chat Sticker NFT, which allow users to obtain unique tokens issued by DMTP based on the activity, will improve the user experience (UX) and enable users to enjoy communicating with each other.

Metawork is a communication and collaboration OS for Web3. It focuses on messaging and community collaboration, and provides unified Web3 tooling by leveraging interoperability between protocols and dApps.
