Authentication System:
- Implements JWT-based session management.
- Sessions expire within 1 hour and are deleted upon logout.
- Sessions store the wallet address and user level based on NFT assets.
-
User Levels:
- 🥈 Silver Member: Browse the marketplace.
- 🥇 Gold Member: Buy items and validate delivery.
- 💎 Platinum Member: Full access, including withdrawing funds.
-
Transaction Management:
- Currency stored in smart contracts when buying items.
- Users can validate delivery and mark transactions as "done."
-
Smart Contract Constructors:
- Validate withdrawals.
- Update delivery status in the datum (pending → done).
- Users connect their wallet to create a session.
- Sessions are stored in cookies, securely maintaining:
- Wallet Address.
- User Level (determined by NFT ownership).
- Session validity is checked on every page load, allowing seamless navigation while ensuring security.
- Ownership Validation: Transactions are bound to their respective owners.
- Withdrawals: Platinum members can withdraw funds collected from sales.
- State Updates: Delivery status can be updated from "pending" to "done" only by the transaction owner.
- Notifications:
- Added authentication notifications for a smoother user experience.
- Parent Layout:
- Simplified wallet connection to one-time per session.
- Easier navigation between pages.
- Refresh Button:
- Allows users to load new transactions without refreshing the entire page.
- Modularity:
- Grouping auth and service on api, utilizations, and smart contract script and transaction builder in their own folder, to reduce redundancy and improve maintainability.
