VibeFactory Contract

The VibeFactory contract is the core factory for creating Real-Time Asset (RTA) NFTs and managing their delegation system. It extends ERC-721 functionality with integrated delegation management.

Contract Overview

Address: 0x49B2E60fF51B107624be84363B718cfF292A0517
Standard: ERC-721 (NFT) with custom extensions
Features: RTA creation, delegation management, cross-contract integration

Core Functions

Creating RTAs

Basic RTA Creation

function createVibestream(
    string calldata mode,
    bool storeToFilecoin,
    uint256 distance,
    string calldata metadataURI,
    uint256 ticketsAmount,
    uint256 ticketPrice,
    bool payPerStream,
    uint256 streamPrice
) external returns (uint256 vibeId)

Creates a new RTA NFT with the specified parameters. Parameters:

mode: Stream mode identifier
storeToFilecoin: Whether to store content on Filecoin
distance: Geographic constraint in meters
metadataURI: IPFS URI for metadata
ticketsAmount: Number of tickets available (0 for no tickets)
ticketPrice: Price per ticket in wei
payPerStream: Enable real-time payments via PPM
streamPrice: Payment rate per minute in wei

Returns: The newly created RTA’s unique identifier

RTA Creation with Delegation

function createVibestreamWithDelegate(
    string calldata mode,
    bool storeToFilecoin,
    uint256 distance,
    string calldata metadataURI,
    uint256 ticketsAmount,
    uint256 ticketPrice,
    bool payPerStream,
    uint256 streamPrice,
    address delegatee
) external returns (uint256 vibeId)

Creates an RTA and sets up delegation in a single transaction.

Delegation System

The VibeFactory implements a ProxyAdmin-based delegation system that allows RTA creators to authorize others to manage their vibestreams.

Setting Delegates

function setDelegate(uint256 vibeId, address delegatee) external

Sets a delegate for a specific RTA. Can only be called by:

ProxyAdmin
ProxyAdmin owner
RTA creator (through authorized addresses)

Removing Delegates

function removeDelegate(uint256 vibeId) external

Removes the delegate for an RTA.

Authorization Management

function addAuthorizedAddress(address _address) external
function removeAuthorizedAddress(address _address) external

Manages the global whitelist of authorized addresses that can perform delegation operations.

Access Control

Permission Hierarchy

Contract Owner: Full administrative control
ProxyAdmin: Delegation management across all RTAs
Authorized Addresses: Global permissions for delegation
RTA Creator: Permissions for their specific RTAs
Delegates: Permissions for delegated RTAs

Modifier: `canModifyVibestream`

modifier canModifyVibestream(uint256 vibeId) {
    bool isCreator = vibestreams[vibeId].creator == msg.sender;
    bool isAuthorizedAddress = authorizedAddresses[msg.sender];
    bool isProxyAdmin = msg.sender == proxyAdmin;
    bool isDelegated = vibeDelegates[vibeId] == msg.sender;
    
    require(isCreator || isAuthorizedAddress || isProxyAdmin || isDelegated, 
            "Not authorized to modify vibestream");
    _;
}

RTA Management

Metadata Updates

function setMetadataURI(uint256 vibeId, string calldata newMetadataURI) external

Updates the metadata URI for an RTA. Requires canModifyVibestream permission.

Finalization

function setFinalized(uint256 vibeId) external

Marks an RTA as finalized. This is a one-way operation that cannot be reversed.

Cross-Contract Integration

PPM Integration

When creating RTAs with payPerStream = true, the contract automatically registers the vibestream with the PPM contract:

if (payPerStream && streamPrice > 0 && ppmContract != address(0)) {
    IPPM(ppmContract).registerVibestream(vibeId, msg.sender, streamPrice);
}

VibeKiosk Integration

RTAs with ticketsAmount > 0 are registered with the VibeKiosk for ticket sales:

if (ticketsAmount > 0 && vibeKiosk != address(0)) {
    IVibeKiosk(vibeKiosk).registerVibestream(
        vibeId, 
        msg.sender, 
        ticketsAmount, 
        ticketPrice, 
        distance
    );
}

View Functions

RTA Data Retrieval

function getVibestream(uint256 vibeId) external view returns (VibeData memory)

Returns complete RTA data structure.

function getDelegate(uint256 vibeId) external view returns (address)

Returns the current delegate for an RTA.

function isAuthorized(address _address) external view returns (bool)

Checks if an address is globally authorized.

Events

RTA Creation

event VibestreamCreated(
    uint256 indexed vibeId,
    address indexed creator,
    uint256 timestamp,
    string mode,
    uint256 ticketsAmount,
    uint256 ticketPrice,
    address requestedDelegatee
);

Delegation Events

event DelegateSet(uint256 indexed vibeId, address indexed delegatee);
event AuthorizedAddressAdded(address indexed newAddress);
event AuthorizedAddressRemoved(address indexed removedAddress);

Gas Optimization

Gas Buffer

The contract implements a gas buffer mechanism to prevent operations from failing due to insufficient gas:

uint256 private constant MIN_GAS_BUFFER = 50000; // 50k gas buffer

modifier hasEnoughGas() {
    require(gasleft() > MIN_GAS_BUFFER, "Insufficient gas for operation");
    _;
}

Security Features

Reentrancy Protection

All state-changing functions use OpenZeppelin’s ReentrancyGuard:

contract VibeFactory is ERC721URIStorage, Ownable, ReentrancyGuard

Input Validation

Comprehensive validation on all parameters:

require(_treasuryReceiver != address(0), "Invalid treasury receiver");
require(bytes(mode).length > 0, "Mode cannot be empty");
require(bytes(metadataURI).length > 0, "Metadata URI cannot be empty");

Usage Examples

Creating a Basic RTA

uint256 vibeId = vibeFactory.createVibestream(
    "live",              // Live streaming mode
    true,                // Store on Filecoin
    1000,                // 1km radius
    "ipfs://metadata",   // Metadata URI
    0,                   // No tickets
    0,                   // No ticket price
    true,                // Enable PPM
    0.01 ether          // 0.01 tMETIS per minute
);

Creating RTA with Tickets and Delegation

uint256 vibeId = vibeFactory.createVibestreamWithDelegate(
    "event",             // Event mode
    false,               // No Filecoin storage
    500,                 // 500m radius
    "ipfs://event-meta", // Event metadata
    100,                 // 100 tickets
    0.1 ether,          // 0.1 tMETIS per ticket
    false,               // No PPM
    0,                   // No streaming price
    delegateAddress      // Delegate address
);
