cd stellar-asset-tokenization-suite

# Install dependencies
npm install

# Build the SDK
npm run build:sdk

npm run build:ui

Soroban Contract Setup

# Install Soroban CLI
cargo install soroban-cli

# Build contracts
cd src
cargo build --target wasm32-unknown-unknown --release

# Deploy contracts (testnet)
soroban contract deploy --wasm target/wasm32-unknown-unknown/release/rwa_token.wasm --network testnet

SDK Usage

import { createStellarRWASDK, AssetType, Currency } from './sdk/src';

// Initialize SDK for testnet
const sdk = createStellarRWASDK('testnet', {
  assetFactory: 'GC...',
  complianceRegistry: 'GD...',
  dividendDistributor: 'GE...',
  secondaryMarket: 'GF...',
  custodyValidator: 'GH...'
});

// Deploy a new RWA token
const token = await sdk.assetFactory.deployRWAToken(deployer, {
  name: 'Manhattan Office Tower',
  symbol: 'MOT',
  totalSupply: '1000000',
  decimals: 18,
  assetType: AssetType.REAL_ESTATE,
  metadata: {
    property_address: '350 Fifth Avenue, New York, NY',
    square_footage: '500000',
    appraisal_value: '10000000'
  },
  complianceRegistry: sdk.getConfig().contracts.complianceRegistry,
  dividendDistributor: sdk.getConfig().contracts.dividendDistributor
});

React UI Integration

import AssetDeployer from './components/AssetDeployer';
import OwnershipDashboard from './components/OwnershipDashboard';

function App() {
  const handleDeploy = async (options) => {
    // Deploy asset using SDK
    return await sdk.assetFactory.deployRWAToken(deployer, options);
  };

  return (
    <div>
      <AssetDeployer onDeploy={handleDeploy} />
      <OwnershipDashboard userAddress={userAddress} portfolio={portfolio} />
    </div>
  );
}

Architecture Overview

The Stellar RWA Tokenization Suite follows a modular architecture:

Smart Contracts Layer: Soroban contracts on Stellar blockchain
SDK Layer: TypeScript client for contract interaction
UI Layer: React components for user interface
Examples Layer: Real-world use case implementations

Smart Contracts

Asset Factory Contract

Deploys new RWA token contracts
Manages token registry and metadata
Supports different asset types (real estate, commodities, securities)

RWA Token Contract

ERC-20 compatible token functionality
Fractional ownership with 18 decimal precision
Built-in compliance checks and transfer restrictions
Voting rights and token locking for governance

Compliance Registry Contract

KYC/AML status management
Whitelist/blacklist functionality
SEC compliance (Rule 144, Reg D, Reg S)
Transfer limits and geographic restrictions

Dividend Distributor Contract

Multi-currency dividend distribution
Support for XLM, USDC, EURC, and custom tokens
Fee calculation and collection
Claim deadline management

Secondary Market Contract

Order book with price discovery
Buy/sell order matching
Trading fees and settlement
Market statistics and history

Custody Validator Contract

Off-chain asset verification
Oracle integration for price feeds
Audit report storage
Insurance coverage verification

SDK Architecture

The TypeScript SDK provides a clean, type-safe interface for interacting with the RWA contracts:

// Main SDK class
class StellarRWASDK {
  assetFactory: AssetFactory;
  tokenClient: TokenClient;
  dividendClient: DividendClient;
  marketClient: MarketClient;
  complianceClient: ComplianceClient;
}

// Individual client classes
class AssetFactory {
  deployRWAToken(options: DeploymentOptions): Promise<DeploymentResult>;
  getAssetInfo(symbol: string): Promise<AssetInfo>;
  listAssets(): Promise<AssetInfo[]>;
}

class TokenClient {
  transfer(from: Address, to: Address, amount: string): Promise<string>;
  mint(to: Address, amount: string): Promise<string>;
  lockTokens(owner: Address, amount: string, period: number): Promise<string>;
}

Compliance Framework

The suite includes comprehensive compliance features:

SEC Compliance

Rule 144: Restricted securities resale limitations
Regulation D: Private placement exemptions (506(c))
Regulation S: Non-US offerings
Accredited Investor Verification: Net worth and income checks

KYC/AML

Multi-level verification (Basic, Enhanced, Institutional)
Risk scoring and AML flagging
Geographic restrictions and sanctions screening
Transfer limits and monitoring

International Compliance

MiFID II (EU) compliance
Tax treaty optimization
Cross-border transfer validation
Multi-currency support with tax withholding
