$SUI (SUI) is a high-performance Layer 1 blockchain and smart contract platform that uses a unique object-centric data model and the Move programming language to enable parallel transaction execution and sub-second finality. Developed by Mysten Labs—a team of former Meta engineers—$SUI is designed for massive scalability, supporting high-throughput applications like DeFi, Web3 gaming, and real-world assets without the typical trade-offs of sequential processing. As of late March 2026, the #SUI token is ranked approximately #17–#18 by market capitalization (around $6.8 billion), with a circulating supply of roughly 3.8 billion out of a fixed maximum of 10 billion tokens. The token serves as the network's native asset for paying gas fees, participating in delegated proof-of-stake (DPoS) for security rewards, and engaging in on-chain governance.
