- Ensure transparency and accountability for fund usage.
- Reduce the reliance on third-party platforms.
- Provide a global platform for equitable funding opportunities.
3. Key Components
3.1 Blockchain Platform
- Choose platforms like Ethereum, Binance Smart Chain, or Solana.
- Prioritize scalability, low transaction fees, and security.
3.2 Smart Contracts
- Automate funding, milestone payments, and refunds.
- Ensure accountability with predefined conditions for fund release.
3.3 Wallet Integration
- Support wallets like MetaMask or WalletConnect for contributions.
- Enable seamless fund management for users.
3.4 User Interface
- Design portals for project creation, funding, and progress tracking.
- Provide dashboards for backers and creators.
3.5 Payment Gateways
- Enable support for cryptocurrencies and stablecoins for transactions.
