Tajiri - Blockchain-Based Stock Trading Platform

Tajiri is a cutting-edge, blockchain-based financial platform designed to tokenize and trade stocks from the Nairobi Securities Exchange (NSE), with a mission to democratize wealth creation in Africa. Deployed on the Hedera blockchain, this app leverages stablecoins for transactions, incorporates account abstraction for user-friendliness, and features a modern Next.js frontend.

Features

• Hedera Blockchain: Built on Hedera Hashgraph for high throughput, low fees, and enterprise-grade reliability
• Stablecoin Trading: Purchase and trade tokenized NSE stocks using stablecoins (USDC, USDT)
• Account Abstraction: Simplified blockchain interactions, making the app intuitive for all users
• Advanced Trading Tools: Interactive charts, technical analysis, and market data
• Lending Protocol: Borrow against tokenized stocks or lend stablecoins for interest
• Educational Resources: Comprehensive learning tools for investors of all experience levels

Account Abstraction Implementation

Tajiri uses advanced account abstraction features to simplify user interaction with blockchain technology:

1. Smart Contract Wallets: Users interact with the blockchain through their personal smart contract wallet that handles transaction complexity and gas fees.

2. Social Recovery: Our smart wallets include guardian-based recovery, allowing users to regain access to their accounts if they lose their private keys.

3. Gasless Transactions: Tajiri can sponsor gas fees for certain transactions, removing the need for users to hold HBAR just for transaction fees.

4. Batched Transactions: Multiple actions (e.g., approve and swap) can be executed in a single transaction, reducing fees and improving UX.

5. Enhanced Security: Transaction authorization is more flexible, with options for multi-signature approvals and guardian-based recovery.

To deploy the smart contracts that power these features:

# In the frontend directory
npm run deploy-contracts

Tech Stack

• Frontend: Next.js with TypeScript, Tailwind CSS
• Blockchain: Hedera Hashgraph with Hedera Token Service (HTS) and Smart Contract Service (HSCS)
• Smart Contracts: Solidity for trading and lending logic
• Libraries: @hashgraph/sdk, react-chartjs-2

Getting Started

Prerequisites

• Node.js 18.x or higher
• npm or yarn
• Hedera Testnet account (for development)

Installation

1. Clone the repository:

   git clone https://github.com/oumaoumag/tajiri-v2.git
   cd tajiri-v2

2. Install dependencies:

   # Install frontend dependencies
