How does crab work?

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

Getting the environment variables

• 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.

Getting login emails locally

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