REQUIREMENTS
Application Requirements — Card Trading App (Web2-Friendly Web3 Integration)
- User Authentication and Onboarding
- Users must be able to sign up using an email and password or Social signup
- Users must be able to log in using their email and password or Social login
- All authentication should be handled securely, adhering to modern security best practices (e.g., hashed passwords, secure sessions, rate limiting).
- Payment and Checkout
- The app must support fiat-based payments, including:
- Credit/debit cards
- PayPal
- (Optional: local payment gateways per region)
- Fiat payments must be usable for minting NFTs, enabling seamless checkout without needing crypto wallets or tokens (or the wallets/tokens are in the background not visible to the user)
- NFT Minting and Card Generation
- Each fiat payment for minting must result in the creation of an NFT on an EVM-compatible chain.
- Each NFT corresponds to a unique digital card, which the user can view, trade, or showcase.
- The card should be generated and linked to the NFT upon successful minting.
- Wallet Abstraction and Ownership
- Users must retain full ownership of their NFTs, even if they never interact directly with private keys.
- The app must abstract away blockchain complexity via one or more of the following methods:
- Custodial wallets or smart account/wallet abstraction (e.g., account abstraction via ERC-4337)
- Secure, recoverable key management (e.g., MPC, email-based recovery)
