Campaign Management

Campaigns are the heart of Oak Network. This section covers how campaigns work, their lifecycle, and how to manage them effectively.

Campaign Structure

CampaignData

Every campaign is defined by a CampaignData struct:

struct CampaignData {
    uint256 launchTime;    // When the campaign becomes active
    uint256 deadline;      // When the campaign ends
    uint256 goalAmount;    // Target amount to raise
}

Campaign States

Campaigns can exist in several states:

Created: Campaign created but not yet active
Active: Campaign is live and accepting contributions
Paused: Campaign temporarily suspended
Cancelled: Campaign permanently cancelled
Successful: Campaign reached its goal
Failed: Campaign deadline passed without reaching goal

Campaign Creation

Prerequisites

Before creating a campaign, ensure you have:

Valid Creator Address: Must be a valid Ethereum address
Unique Identifier: Each campaign needs a unique bytes32 identifier
Selected Platforms: At least one platform must be selected
Valid Parameters: Launch time, deadline, and goal amount must be valid

Creation Process

// 1. Prepare campaign data
CampaignData memory campaignData = CampaignData({
    launchTime: block.timestamp + 1 days,    // Launch in 1 day
    deadline: block.timestamp + 30 days,     // 30-day campaign
    goalAmount: 10000 * 10**18               // $10,000 goal
});

// 2. Select platforms
bytes32[] memory platforms = new bytes32[](2);
platforms[0] = keccak256("platform1");
platforms[1] = keccak256("platform2");

// 3. Create campaign
factory.createCampaign(
    creator,
    identifierHash,
    platforms,
    platformDataKeys,
    platformDataValues,
    campaignData
);

Validation Rules

The protocol enforces several validation rules:

Launch Time: Must be in the future
Deadline: Must be after launch time
Goal Amount: Must be greater than zero
Platforms: Must be listed and valid
Identifier: Must be unique across all campaigns

Parameter Updates

Campaign owners can update certain parameters before the campaign launches:

Launch Time Update

function updateLaunchTime(uint256 newLaunchTime) external onlyOwner {
    // Can only update before current launch time
    require(block.timestamp < getLaunchTime(), "Campaign already launched");
    require(newLaunchTime > block.timestamp, "Invalid launch time");
    require(newLaunchTime < getDeadline(), "Launch time must be before deadline");
    
    s_campaignData.launchTime = newLaunchTime;
    emit CampaignInfoLaunchTimeUpdated(newLaunchTime);
}

Deadline Update

function updateDeadline(uint256 newDeadline) external onlyOwner {
    // Can only update before launch
    require(block.timestamp < getLaunchTime(), "Campaign already launched");
    require(newDeadline > getLaunchTime(), "Deadline must be after launch");
    
    s_campaignData.deadline = newDeadline;
    emit CampaignInfoDeadlineUpdated(newDeadline);
}

Goal Amount Update

function updateGoalAmount(uint256 newGoalAmount) external onlyOwner {
    // Can only update before launch
    require(block.timestamp < getLaunchTime(), "Campaign already launched");
    require(newGoalAmount > 0, "Goal amount must be positive");
    
    s_campaignData.goalAmount = newGoalAmount;
    emit CampaignInfoGoalAmountUpdated(newGoalAmount);
}

Platform Management

Adding Platforms

function updateSelectedPlatform(
    bytes32 platformHash,
    bool selection
) external onlyOwner {
    // Can only update before launch
    require(block.timestamp < getLaunchTime(), "Campaign already launched");
    
    // Platform must be listed
    require(
        GLOBAL_PARAMS.checkIfPlatformIsListed(platformHash),
        "Platform not listed"
    );
    
    // Cannot deselect approved platforms
    if (!selection && checkIfPlatformApproved(platformHash)) {
        revert("Cannot deselect approved platform");
    }
    
    s_isSelectedPlatform[platformHash] = selection;
    emit CampaignInfoSelectedPlatformUpdated(platformHash, selection);
}

Campaign Lifecycle Events

Key Events

// Campaign created
event CampaignInfoFactoryCampaignCreated(
    bytes32 indexed identifierHash,
    address indexed campaignAddress
);

// Parameter updates
event CampaignInfoLaunchTimeUpdated(uint256 newLaunchTime);
event CampaignInfoDeadlineUpdated(uint256 newDeadline);
event CampaignInfoGoalAmountUpdated(uint256 newGoalAmount);

// Platform management
event CampaignInfoSelectedPlatformUpdated(
    bytes32 indexed platformHash,
    bool selection
);

event CampaignInfoPlatformInfoUpdated(
    bytes32 indexed platformHash,
    address indexed platformTreasury
);

State Transitions

Access Control

Owner Functions

Only the campaign owner can:

Update campaign parameters (before launch)
Transfer ownership
Cancel the campaign

Admin Functions

Protocol and platform admins can:

Pause/unpause campaigns
Cancel campaigns (in emergencies)
Access campaign data

Public Functions

Anyone can:

View campaign information
Contribute to active campaigns
Claim refunds (when applicable)

Best Practices

Campaign Design

Realistic Goals: Set achievable funding targets
Appropriate Timeline: Balance urgency with feasibility
Clear Communication: Provide detailed campaign information
Platform Selection: Choose platforms that align with your audience

Security Considerations

Parameter Validation: Always validate user inputs
Access Control: Implement proper permission checks
Emergency Procedures: Have plans for pausing/cancelling
Regular Monitoring: Monitor campaign progress and health

Gas Optimization

Batch Operations: Group related operations when possible
Efficient Storage: Use appropriate data types
Event Optimization: Emit only necessary events
Function Optimization: Minimize external calls

Common Patterns

Campaign Factory Pattern

contract MyCampaignFactory {
    ICampaignInfoFactory public oakFactory;
    
    function createMyCampaign(
        address creator,
        string memory name,
        uint256 goal,
        uint256 duration
    ) external {
        // Custom validation
        require(bytes(name).length > 0, "Name required");
        require(goal > 0, "Invalid goal");
        
        // Create campaign
        bytes32 identifier = keccak256(abi.encodePacked(name, creator, block.timestamp));
        CampaignData memory data = CampaignData({
            launchTime: block.timestamp,
            deadline: block.timestamp + duration,
            goalAmount: goal
        });
        
        oakFactory.createCampaign(creator, identifier, platforms, keys, values, data);
    }
}

Campaign Monitoring

contract CampaignMonitor {
    function checkCampaignHealth(address campaign) external view returns (bool) {
        ICampaignInfo info = ICampaignInfo(campaign);
        
        // Check if campaign is active
        if (info.paused() || info.cancelled()) {
            return false;
        }
        
        // Check if campaign is within time bounds
        uint256 now = block.timestamp;
        if (now < info.getLaunchTime() || now > info.getDeadline()) {
            return false;
        }
        
        // Check if campaign has reasonable progress
        uint256 raised = info.getTotalRaisedAmount();
        uint256 goal = info.getGoalAmount();
        uint256 progress = (raised * 100) / goal;
        
        // Consider campaign healthy if it has some progress or is early
        return progress > 5 || (now - info.getLaunchTime()) < 7 days;
    }
}
