Authentication

Beforehand uses Privy for wallet-based authentication.

How It Works​

Sign Up​

  1. User provides phone number
  2. Privy creates embedded wallet
  3. Wallet address linked to phone number
  4. User profile created in database

Sign In​

  1. User enters phone number
  2. Privy verifies (SMS code)
  3. Wallet unlocked
  4. User authenticated

Wallet Model​

  • Non-custodial: User owns private keys
  • Embedded: Created automatically, no seed phrase needed
  • Recoverable: Can be recovered via phone number
  • Exportable: User can export wallet if needed

Integration​

  • Frontend: Privy React hooks for auth state
  • Database: Links Privy user ID to profile
  • Contracts: Wallet address used for transactions
  • Security: Row-level security based on user ID

Benefits​

  • Simple UX: No complex wallet setup
  • Recovery: Phone-based recovery
  • Security: Non-custodial, user controls funds
  • Flexibility: Can add social login later
