- Ensure secure and transparent loan agreements.
- Enable global access to financial services for unbanked populations.
- Minimize costs and improve efficiency through smart contracts.
3. Key Components
3.1 Blockchain Platform
- Use Ethereum, Binance Smart Chain, or Solana for secure transactions.
- Focus on scalability, low fees, and interoperability.
3.2 Smart Contracts
- Automate loan agreements, repayments, and collateral management.
- Ensure compliance with predefined terms.
3.3 Collateral Management
- Enable collateral deposits in crypto tokens.
- Implement liquidation processes for defaults.
3.4 User Interface
- Design portals for loan applications, approvals, and tracking.
- Provide dashboards for both lenders and borrowers.
3.5 Wallet Integration
- Allow users to connect wallets like MetaMask or Trust Wallet for transactions.
- Support crypto payments and tokenized collateral.
4. System Architecture
4.1 User Roles
1. Lenders: Provide funds for microloans.
2. Borrowers: Apply for and repay loans.
