You can think of Sui as a developer-friendly chain that’s designed to support apps needing both speed and flexibility. In DeFi, it’s great for protocols that demand low fees and fast settlement since transactions can finalize in under a second. For NFTs, you’re not limited to static images because Sui’s object model lets tokens evolve, combine with others, or even carry their own assets, which unlocks creative designs like upgradable collectibles. Games benefit because they need real-time interactions at scale and Sui’s parallel execution model helps avoid bottlenecks when thousands of players are transacting at once. Social apps also fit well since digital assets like profiles, posts, or badges can remain dynamic and composable instead of frozen data.
