RWA Tokenization Reference 🏗️

ERC-3643 compliant real world asset tokenization smart contract examples on Ethereum, Polygon, Solana and Avalanche. By Blockhertz

What is RWA Tokenization?

Real world asset tokenization creates digital tokens on blockchain that represent ownership of physical or financial assets — real estate, bonds, gold, carbon credits, and more.

$52 billion in assets are already tokenized on-chain in 2026. BlackRock, JPMorgan, and Coinbase are all doing it at institutional scale.

🔐 Security Standards

All contracts follow:

• ERC-3643 / T-REX standard
• OpenZeppelin security libraries
• Checks-Effects-Interactions pattern
• Role-based access control
• Chainlink oracle integration

---

⚠️ Security First

Before deploying any RWA contract to mainnet — audit it first.

Free AI audit: blockhertz.com/tools/ai-auditor

Common RWA vulnerabilities:

• Missing access control on whitelist
• Reentrancy in yield distribution
• Oracle price manipulation
• Transfer restriction bypasses
