Solana Loan Platform

A decentralized lending platform built on Solana that enables peer-to-peer loans with customizable terms.

🏗 Project Structure

The project consists of three main components: # LoanMe

LoanMe is a decentralized lending platform built on Solana, enabling users to create, manage, and repay loans in a trustless environment. The platform leverages Anchor for Solana smart contracts, Flask for backend APIs, and SQLite for lightweight data storage.

Features

• Loan Management: Borrowers can request loans, and lenders can fund them.
• Solana Smart Contracts: Powered by Anchor to ensure security and transparency.
• Wallet Integration: Users can generate and manage Solana wallets.
• Payment Processing: Borrowers can make repayments via smart contracts.
• API-Driven: Exposes RESTful APIs for frontend integration.

Installation

1. Clone the Repository

git clone https://github.com/robertwbattle/LoanMe.git
cd LoanMe

2. Install Dependencies

Backend Requirements

pip install -r requirements.txt

Solana & Anchor (For Smart Contracts)

Ensure you have Anchor & Solana CLI installed:

sh -c "$(curl -sSfL https://release.solana.com/stable/install)"
npm install -g @coral-xyz/anchor-cli

Verify installation:

solana --version
anchor --version

Configuration

1. Set Up Environment Variables

Create a .env file inside the backend/ directory and configure:

SOLANA_RPC_URL="https://api.devnet.solana.com"
WALLET_PRIVATE_KEY="[YOUR_SOLANA_PRIVATE_KEY]"
PROGRAM_ID="[YOUR_DEPLOYED_PROGRAM_ID]"
TATUM_API_KEY="[YOUR_TATUM_API_KEY]"
TATUM_API_URL="[TATUM_API_ENDPOINT]"

2. Set Up SQLite Database

cd backend
python setup_db.py  # Initializes the database

Running the Project

1. Start the Flask Backend

cd backend
python app.py

The API will be available at http://127.0.0.1:5000

2. Deploy the Smart Contract

cd anchor
anchor build
anchor deploy
