Tari Marketplace MVP

This is a minimal viable product (MVP) for a decentralized marketplace built on the Tari network. It mimics the core functionality of platforms like Etsy, but for digital assets represented as Tari Digital Assets (TDAs) and transacted in XTR.

🛠️ Setup Instructions

1. Smart Contract

Build and deploy to Tari Layer 2 (DAN)

Requires:

• Tari template SDK
• Rust toolchain

cd smart_contract
# Build & deploy instructions based on Tari SDK documentation

2. Indexing Service

Rust backend with PostgreSQL

Requirements

• Rust
• PostgreSQL

Setup

cargo run

3. Frontend

Requirements

• Node.js + npm

Setup

cd frontend
npm install
npm start

🧪 Mock Components

• Wallet: Uses mockWallet for demo
• Event Listener: Polling stub for future Tari DAN integration

---

📌 Limitations (MVP Scope)

• No minting (assumed external)
• No advanced search/filtering
• XTR only, fixed price sales
• No physical goods support
• Centralized read indexing
