Problem Statement
🧩 1. RWA Tokenization Is Fragmented
The current state of tokenized real-world assets (RWAs) is siloed:
Treasuries on Ethereum
Carbon credits on Solana
Real estate on Polygon
Equity shares on private subnets
This chain fragmentation breaks liquidity, interoperability, and legal continuity.
🔍 There is no unified protocol to legally and technically transfer regulated RWAs across ecosystems.
🔓 2. Bridges Aren’t Built for Compliance
Most cross-chain protocols:
Treat tokens as generic fungibles
Can’t handle jurisdictional rules
Don’t enforce whitelists, caps, or legal terms
🔐 You can’t bridge a tokenized security the same way you bridge a meme coin.
Without compliance:
Institutions can’t use the rails
Regulated assets can't scale
Transfers become legally void across jurisdictions
⚠️ 3. Traditional Cryptography Is Becoming Obsolete
RSA
Broken by Shor’s algorithm
ECDSA
Vulnerable to quantum attack
AES-128
At risk from Grover’s speedup
🧬 Bridges using today’s cryptographic standards are vulnerable to tomorrow’s quantum threats.
QBridge is built using NIST-approved post-quantum cryptography from the ground up — not as a patch.

🛠 QBridge is built to solve this:
✅ Unifies fragmented RWA ecosystems
✅ Enforces legal compliance programmatically
✅ Uses quantum-resistant infrastructure
