Understanding the Cycle of Your Smart Contract (NFTFlex)

Your NFTFlex contract allows NFT owners to list their NFTs for rent, enabling renters to borrow them for a specified time. Here’s how the cycle works:

1. Creating a Rental (By NFT Owner - Account 1)

   • The owner of an NFT calls createRental() to list their NFT for rent.
   • They specify the NFT contract address, token ID, price per hour, whether the rental is fractional, collateral token address, and collateral amount.
   • This creates a rental entry in s_rentals and emits an event NFTFlex__RentalCreated.

2. Renting an NFT (By Renter - Account 2)

   • A user who wants to rent the NFT calls rentNFT() with the rentalId and duration (in hours).
   • They must send enough ETH (or ERC20 tokens) to cover both the rental fee and collateral.
   • If successful:
     • The renter field is updated to the caller’s address.
     • The rental start and end times are set.
     • The event NFTFlex__RentalStarted is emitted.
   • If anything is wrong (e.g., incorrect payment, already rented NFT, etc.), the function reverts with an error, which we can capture in the frontend.

3. Ending the Rental (By Renter - Account 2)

   • When the rental period is over, the renter calls endRental().
   • The function checks:
     • The caller is the correct renter.
     • The rental period has ended.
   • If successful:
     • The renter’s collateral is refunded.
     • The rental is marked as available.
     • The event NFTFlex__RentalEnded is emitted.

4. Withdrawing Earnings (By NFT Owner - Account 1)

   • After a rental ends, the owner can call withdrawEarnings().
   • The function checks:
     • The caller is the owner.
     • The rental has ended.
   • The contract transfers the rental fee (excluding collateral) to the owner.
   • The event NFTFlex__EarningTransferFailed is emitted if it fails.

Summary

• Account 1 (NFT Owner): Calls createRental() to list an NFT, later calls withdrawEarnings() to collect rent.
• Account 2 (Renter): Calls rentNFT() to borrow an NFT, later calls endRental() to return it.
• Account 3 (Another User): Can rent NFTs, interact with events, and observe state changes.

Frontend Features

• Error Handling: Catches errors and displays them in Vue.js.
• Event Listeners: Listens for contract events to update UI in real-time.
• Metamask Integration: Allows users to interact with the contract via Metamask.
