Smart Contracts
Real estate is the largest asset class in the world at $326 trillion. Less than 1% of it is tokenized. The gap between where the market is and where it is going represents one of the biggest opportunities in blockchain — and one of the most technically complex builds to get right.
Blockchain
$3.4 billion stolen from blockchain projects in 2025. Access control failures cost $953 million. Audited contracts have 98% fewer hacks. Complete blockchain security statistics for 2026 — updated monthly by the Blockhertz team.

Polygon has become the default chain for institutional RWA tokenization — low fees, EVM compatibility, and established relationships with BlackRock, JPMorgan, and Coinbase. This is the complete developer guide to building a production-ready RWA tokenization platform on Polygon from architecture to mainnet launch.

$3.4 billion was stolen from blockchain projects in 2025. RWA tokenization platforms are high-value targets — real assets, real legal obligations, real money. These are the 10 smart contract vulnerabilities that destroy tokenization projects, and how to fix every one of them before you launch.
Development
Real world asset tokenization is turning $52 billion in physical and financial assets into programmable blockchain tokens — and institutions like BlackRock, JPMorgan, and Coinbase are already doing it at scale. Here is the plain-English guide to how it works, what it takes to build, and why 2026 is the year it went mainstream.
