How FanHub Was Built

FanHub combines the power of Oasis Sapphire's privacy features with user-friendly authentication through Privy. Here's how we built it:

Core Authentication & Wallet Integration

We prioritized accessibility while maintaining security by implementing multiple login options:

User Authentication (Privy)

We integrated Privy to provide flexible authentication options:

• Wallet-based login (primary method)
• Email authentication
• SMS verification
• Embedded wallet creation for new Web3 users

The system automatically creates wallets for users who don't have them, making the platform accessible to crypto newcomers while maintaining security with password protection.

Blockchain Integration (Wagmi + Sapphire)

We built on Oasis Sapphire's privacy-focused blockchain infrastructure:

• Support for multiple Sapphire networks (mainnet, testnet, localnet)
• Custom HTTP transport layer for Sapphire-specific interactions
• Integrated wallet connectors optimized for Sapphire's privacy features
