Sui strengthens security by combining multiple layers of protection. The Move language enforces strict rules that stop assets from being duplicated or accidentally lost, while formal verification tools allow you to mathematically check critical contracts before they go live. On top of that, Sui’s object-centric ownership model makes asset management more transparent and less prone to common vulnerabilities seen in account-based blockchains. Together, these features make it much harder for bugs or exploits to compromise the network.
