Vitalik Buterin at EthCC stressed the need for real user protections in crypto.  
He suggested practical tests like exit and internal attack checks to ensure safety.  
He warned of hidden risks in layer 2 networks and pushed for default privacy.  
Three key tests: exit (asset safety if project fails), internal attack (resisting insider threats), and trusted code (minimizing trust needed).

Vitalik's focus on user safety is awesome, showing how crypto can be both secure and private with smart checks like exit and attack tests
