Fledge - Secure Crowdfunding on Flare Network

Fledge is a decentralized crowdfunding platform built on the Flare Network that provides built-in price protection for contributors. Our platform ensures that your investments are safe even if token prices drop before the funding goal is reached.

🌟 Key Features

• Price Protection: Rebalance funds and option for contributors to withdraw funds if token price falls
• Secure Campaigns: Built-in price protection for all contributors
• Real-time Tracking: Monitor campaign progress and price movements
• User-Friendly Interface: Intuitive design for both campaign creators and contributors

🔬 Technical Architecture

Smart Contract System

The platform consists of two main smart contracts:

1. CrowdfundingFactory

   • Creates and manages individual campaign contracts
   • Maintains a registry of all campaigns
   • Handles campaign creation and contribution routing
   • Provides pagination and filtering for campaign discovery

2. CrowdfundingCampaign

   • Manages individual campaign logic
   • Integrates with Flare's FTSO (Flare Time Series Oracle) for real-time price feeds
   • Implements price protection mechanism
   • Handles contributions and fund distribution

FTSO Integration

The platform leverages Flare's FTSO system for reliable price feeds:

function getFlrUsdPrice() public returns (uint256 price, int8 decimals, uint64 timestamp) {
    FtsoV2Interface ftsoV2 = ContractRegistry.getFtsoV2();
    return ftsoV2.getFeedById(FLR_USD_ID);
}

Key features of the FTSO integration:

• Real-time FLR/USD price updates
• High accuracy through Flare's decentralized oracle network
• Automatic price protection checks
• Transparent price verification

Price Protection Mechanism

The system implements price protection through:

1. Continuous monitoring of FLR/USD price via FTSO
2. Automatic goal achievement checks based on current price
3. Secure fund distribution only when price conditions are met
4. Transparent campaign finalization process
