# Use Cases & Integrations

### Let's Start

With Web3 social on the rise, Web3 communication remains one of the last undiscovered frontiers. Until now, there was no permissionless infrastructure to enable out-of-the-box on-chain communication application development. With that out of the way, the developer community can now focus on building communication applications with Crypto-specific features and use cases.
