+# Homebase - Real Estate Tokenization Protocol on Polkadot
+
+> This is an application for a Level 3 grant to build a comprehensive real estate tokenization protocol native to the Polkadot ecosystem.
+
+- **Team Name:** Homebase by HanPay  
+- **Payment Details:**
+  - **DOT**: 13QrJsxfwEabrYuDAjQfuEt1iFPJdxWERRVUkAuLbGSv6og8 (≥50% of total grant)
+  - **Payment**: TX5tekNYLZXaVtje6QUMKjEsx9RxteSzC4 (USDC) - TRC-20 Address
+- **Level:** 3  
+
+## Project Overview :page_facing_up:
+
+### Overview
+
+- **Tagline:** Bridging physical real estate and DeFi through trustless tokenization on Polkadot
+- **Brief Description:** Homebase is a Polkadot-native RWA protocol that enables fractional ownership, liquidity, and programmable governance of real estate assets through tokenization, cross-chain integration via XCM, and compliant on-chain trading.
+- **Polkadot Integration:** Built as a custom Substrate parachain with specialized pallets for RWA management, utilizing XCM for cross-chain liquidity and governance across the Polkadot ecosystem.
+- **Team Interest:** Real estate represents the world's largest asset class (~$280 trillion globally) but remains illiquid and inaccessible. We aim to democratize real estate investment while showcasing Polkadot's capabilities for complex real-world asset management.

+```
+
+**Core Components:**
+
+1. **Substrate Runtime Pallets:**
+   - `pallet_rwa_core`: Property registration, metadata management, IPFS document storage
+   - `pallet_rwa_asset`: Fractional token minting, supply management, ownership tracking
+   - `pallet_rwa_marketplace`: On-chain order book, trading, settlement mechanisms
+   - `pallet_rwa_xcm`: Cross-chain asset transfers and governance via XCM
+   - `pallet_rwa_governance`: Token-weighted voting, proposal management
+
+2. **Backend Services (Node.js/Express):**
+   - REST and GraphQL APIs for frontend integration
+   - KYC/AML compliance management
+   - Event streaming from Substrate chain
+   - Admin dashboard for property onboarding
+   - Integration with legal custodians and notaries
+
+3. **Frontend Application (React/TypeScript):**
+   - User dashboard for asset management
+   - Property browsing and investment interface
+   - Governance participation tools
+   - Multi-wallet support (Polkadot.js, Talisman, SubWallet)
+
+**Technology Stack:**
+- **Blockchain:** Substrate framework, Rust programming language
+- **Backend:** Node.js, Express.js, PostgreSQL, Redis
+- **Frontend:** React, TypeScript, Tailwind CSS, Polkadot.js API
+- **Storage:** IPFS for document storage, on-chain metadata
+- **DevOps:** Docker, GitHub Actions, Prometheus, Grafana
+
+**Data Models:**
+
+Property Registration:
+```rust
+pub struct Property {
+    pub id: PropertyId,
+    pub owner: AccountId,
+    pub metadata_hash: Hash, // IPFS hash
+    pub valuation: Balance,
+    pub legal_documents: Vec<Hash>,
+    pub status: PropertyStatus,
+    pub token_supply: Balance,
+    pub created_at: BlockNumber,
+}
+```
+
+Fractional Token:
+```rust
+pub struct PropertyToken {
+    pub property_id: PropertyId,
+    pub total_supply: Balance,
+    pub circulating_supply: Balance,
+    pub holders: BTreeMap<AccountId, Balance>,
+    pub trading_enabled: bool,
+}
+```
+
+**What the project provides:**
+- Trustless real estate tokenization infrastructure
+- Cross-chain liquidity for real estate assets
+- Compliant governance and trading mechanisms
+- Integration with existing legal frameworks
+
+**What the project does NOT provide:**
+- Direct property management services
+- Legal custody of physical assets (handled by partners)
+- Traditional real estate brokerage services
+- Guaranteed returns or investment advice
+
+### Ecosystem Fit
+
+**Position in Polkadot Ecosystem:**
+Homebase fills a critical gap as the first dedicated real estate RWA parachain in Polkadot, providing:
+- Specialized infrastructure for real estate tokenization
+- XCM integration enabling cross-chain DeFi access for real estate assets
+- A bridge between traditional finance and Web3 for institutional adoption
+
+**Target Audience:**
+- Primary: Real estate investors seeking fractional ownership and liquidity
+- Secondary: DeFi protocols wanting exposure to real estate assets
+- Tertiary: Property developers seeking alternative funding mechanisms
+
+**Market Need:**
+The global real estate tokenization market is projected to reach $3.7 trillion by 2030 (according to Boston Consulting Group, 2021). Current pain points include:
+- Lack of liquidity in real estate investments
+- High barriers to entry (minimum investment requirements)
+- Limited geographic diversification options
+- Complex legal frameworks requiring specialized solutions
+
+**Evidence of Need:**
+- 40+ inquiries from potential users during our testnet phase
+- Interest from 3 property management companies in Nigeria and Serbia
+- Positive feedback from real estate lawyers regarding our compliance approach
+
+**Similar Projects Analysis:**
+- **In Polkadot Ecosystem:** No direct competitors focusing specifically on real estate RWA
+- **Other Ecosystems:** RealT (Ethereum), Lofty (Algorand) - our differentiators include:
+  - Native cross-chain capabilities via XCM
+  - More flexible governance mechanisms
+  - Lower transaction costs through Substrate optimization
+  - Better regulatory compliance tools
