What Is Sui (SUI)?

Sui is one of the most talked-about Layer 1 blockchains in crypto right now — and for good reason. Built for speed, scalability, and developer-friendly infrastructure, Sui has quickly positioned itself as a serious contender in the smart contract space. Whether you’ve seen SUI price surging on the charts, heard about its growing DeFi ecosystem, or spotted it on Cwallet, here’s everything you need to know.

What Is Sui Network?

Sui is a Layer 1 blockchain designed for high-speed, low-cost transactions. Unlike traditional blockchains that process transactions one at a time, Sui handles multiple transactions simultaneously — think of it as a multi-lane highway versus a single-lane road. The result is faster confirmations, lower fees, and a smoother experience for users and developers alike.

Sui was built by Mysten Labs, a team of former Meta engineers who previously worked on Meta’s Diem blockchain project. The mainnet launched in May 2023, and the network has grown rapidly since, attracting developers across DeFi, gaming, and NFTs.

What Makes Sui Different?

Two things set Sui apart from most other blockchains: how it processes transactions and how it keeps them secure.

Speed through parallel processing. Most blockchains handle transactions one at a time, like a single checkout lane at a supermarket. Sui works more like a supermarket with dozens of lanes open at once — transactions that don’t affect each other are processed at the same time rather than queued up one behind another. For everyday users, this means near-instant confirmations and very low fees even when the network is busy. In testing, Sui has demonstrated the ability to handle hundreds of thousands of transactions per second.

Security by design. Sui uses a programming language called Move, originally developed by engineers at Meta. Without getting into the technical weeds, what matters for users is the outcome: Move makes it significantly harder for developers to make the kinds of coding mistakes that have led to major hacks and hundreds of millions in lost funds on other blockchains. When you interact with apps built on Sui, there’s a higher baseline of security underneath.

What Is the SUI Token?

SUI is the native cryptocurrency of the Sui network and serves four core purposes.

Gas fees — every transaction on the Sui blockchain requires a small amount of SUI to cover processing costs. The network is designed to keep these fees low and predictable.

Staking — SUI uses a Delegated Proof of Stake (DPoS) system, where token holders can stake SUI with validators to help secure the network and earn staking rewards in return.

Governance — SUI holders can vote on protocol upgrades and key decisions that shape the network’s future. Ecosystem utility — SUI serves as the base asset across DeFi protocols, NFT marketplaces, and dApps built within the Sui ecosystem.

SUI Tokenomics

The total supply of SUI is capped at 10 billion tokens — a fixed maximum supply designed to create long-term scarcity. As of early 2025, approximately 2.9 billion SUI are in circulation, representing around 29% of the total supply.

Token distribution is structured across four main groups:

• Early contributors & investors — funding the initial development and growth of the network
• Mysten Labs treasury — supporting ongoing protocol development and operations
• Sui Foundation community reserve — allocated to developer grants, ecosystem programs, and research
• Validator rewards — distributed to validators and delegators who help secure the network

Notably, there was no SUI airdrop at mainnet launch. This was a deliberate choice to avoid the volatility that typically follows large airdrop events. A one-year cliff was also applied to all initial investor token allocations, ending in May 2024, to reduce the risk of large early sell-offs destabilizing the market.

The Sui Ecosystem

Since its mainnet launch, Sui has built out a growing ecosystem across multiple sectors. On the DeFi side, Cetus Protocol serves as the network’s leading decentralized exchange, offering concentrated liquidity pools and swap functionality. Native USDC has also been introduced on Sui, making on-chain finance more accessible. For NFTs, platforms like Hyperspace and Tradeport provide access to Sui-native digital assets. SuiNS, the network’s name service, lets users replace long wallet addresses with readable identifiers like alice.sui — a small but meaningful improvement for day-to-day usability.

Gaming is another area where Sui is gaining traction, with its high speed and low fees making it a practical foundation for on-chain game mechanics that would be too slow or expensive on other networks.

How to Buy, Swap, and Trade SUI on Cwallet

If you’re looking to get exposure to SUI, Cwallet makes it accessible at every level.
