RWA Tokenization

When to Use

• Tokenizing treasuries (T-bills, government bonds)
• Real estate fractional ownership
• Corporate bond issuance on-chain
• ERC-3643 (T-REX) compliant security tokens
• Yield distribution to token holders

Prerequisites

• MCP: compliance-screening-server, blockchain-rpc-server, price-feed-server
• Skills: skill-09 (mandatory for all RWA), skill-08

Workflow

1. Token Standard Selection

Standard	Use Case	Compliance
ERC-3643 (T-REX)	Regulated securities	Built-in identity/compliance
ERC-1400	Security tokens (legacy)	Partition-based
ERC-4626	Yield-bearing vaults	DeFi composability
ERC-20 + allowlist	Simple restricted tokens	Manual KYC gate

Prefer ERC-3643 for regulated offerings in EU (MiCA) and US (Reg D/Reg S).

2. Issuance Workflow

1. Legal structuring (SPV, fund vehicle)
2. KYC/AML all investors via compliance MCP
3. Deploy identity registry + compliance module
4. Mint tokens to verified investor wallets only
5. Register with applicable regulators (SEC, FCA, etc.)

3. Asset Classes

Tokenized Treasuries (e.g., Ondo OUSG, Franklin FOBXX):

• 1:1 backing with short-term US Treasuries
• Daily/monthly redemption windows
• Accrued yield reflected in token price or rebasing

Real Estate:

• SPV holds property; tokens = beneficial interest
• Distribute rental income via claim() or automatic airdrop
• Secondary trading restricted to qualified investors

Bonds:

• Coupon payments via scheduled distributeYield() calls
• Maturity redemption at par

4. Yield Distribution

function distributeYield(uint256 amount) external onlyManager {
  uint256 totalSupply = token.totalSupply();
  yieldPerToken += (amount * 1e18) / totalSupply;
}

Track tax reporting obligations per jurisdiction (1099-DA, withholding).

5. Compliance Controls

• Transfer restrictions: only between whitelisted addresses
• Force transfer for court orders (ERC-3643 agent role)
• Freeze tokens for sanctioned parties
• Cap table reporting and audit trail

Hard Rules

• All investors must pass KYC/AML before mint
• No public trading without registration exemption
• Screen every transfer via compliance MCP
• Maintain off-chain legal docs linked via hash on-chain
