Integration in RWA tokenization faces key challenges:

1. Interoperability: Bridging blockchain and traditional financial systems requires compatible technologies.

2. Compliance: Ensuring tokenized assets meet legal and regulatory requirements across different regions.

3. Settlement: Synchronizing fast blockchain settlements with slower, legacy financial processes.

4. Legacy Systems: Traditional infrastructure often isn't blockchain-compatible, needing costly upgrades.

5. Real-Time Data: Aligning blockchain's real-time data with traditional batch processing systems.

These hurdles make integration a complex, technical process.
