Decentralized Communities in Web3

Crab is a community-driven, open-source, decentralized network for thriving communities in Web3.

Read the presentation here.

Crab utilizes the Spling Social Protocol to interact with the Shadow Drive, a decentralized file system by GenesysGo in the Solana blockchain.

You can try the official and most recent version of crab at crab.so 🦀

Crab is open-source and you can contribute to the project by opening a pull request or an issue.

It is built with Next.js and Tailwind CSS.

• HELIUS_API_KEY and NEXT_PUBLIC_HELIUS_API_KEY are the API keys required to run the RPC, you can get one by creating an account in helius labs.

• NEXT_PUBLIC_SUPABASE_URL, NEXT_PUBLIC_SUPABASE_ANON_KEY and SUPABASE_SERVICE_ROLE_KEY can be found in your terminal right after you start the Supabase container.

Supabase starts a local inbucket SMTP server that you can use to get login emails locally at http://localhost:54324.
