Aven Smart Contract

This repository contains two Solidity smart contracts that work together to manage events, register users, and issue proof of attendance using NFTs. The contracts are:

1. Aven.sol: Manages user registration, event creation, attendance tracking, and proof of attendance minting.
2. AvenPOA.sol: An ERC-1155 token contract used to mint Proof of Attendance (POA) NFTs for event attendees.

Contract Addresses

Overview

1. Aven Contract

The Aven contract allows users to register on the platform, create events, and track attendance. It also integrates with the AvenPOA contract to issue Proof of Attendance (POA) tokens to users who attend and complete events.

Key Features:

• User Registration: Users can register on the platform by calling registerUser().
• Event Creation: Event creators can create events using createEvent() with details like title, description, start date, and duration.
• Event Sign-up: Users can sign up for events using eventSignup().
• Event Archive: Events can be archived using archiveEvent().
• Proof of Attendance (POA): Users can receive POA tokens upon successful event completion by calling proofOfAttendance().

Events:

• UserRegistered: Emitted when a user registers.
• AttendanceProof: Emitted when a POA token is minted.

2. AvenPOA Contract

The AvenPOA contract is an ERC-1155 token that serves as a Proof of Attendance (POA) for events. It allows the minting of NFTs to users who attended events.

Key Features:

• Minting: The contract owner can mint individual or batch NFTs using mint() and mintBatch().
• URI Management: The contract owner can set the metadata URI for the NFTs.
• Upgradeable: The contract uses the UUPS pattern for upgradeability.

How to Use

1. Deploy AvenPOA Contract: Deploy the AvenPOA contract, initializing the contract with the owner's address.

2. Deploy Aven Contract: Deploy the Aven contract and pass the deployed AvenPOA contract address as a parameter to the constructor.

3. Register Users: Users can register on the platform by calling registerUser().

4. Create Events: Authorized users can create events with relevant details.

5. Attend Events: Users can sign up for events using eventSignup().

6. Mint POA: After the event is completed, users who attended can receive a POA by calling proofOfAttendance().
