Sui Price Tracker (SUI) & Whale Tracker

What is Sui

Sui is a layer-1 blockchain built by Mysten Labs, a company founded in 2021 by five engineers who had led the Diem and Novi crypto projects at Meta: Evan Cheng, Sam Blackshear, Adeniyi Abiodun, George Danezis and Kostas Chalkias. The mainnet launched in May 2023. Its design goal is to make blockchain apps feel like ordinary apps: instant confirmation, cheap fees, logins with a Google account, and no gas prompts for the user.

SUI is the native token. It pays transaction fees and storage costs, is staked to secure the network and votes on governance. Price, market cap and supply figures at the top of this page refresh automatically.

Sui is often paired with Aptos because both grew out of the same Meta project and both use the Move programming language. Sui's version of Move is its own, built around objects rather than accounts, which is the main technical difference between the two chains.

How Sui works

Everything on Sui is an object with an owner. A coin, an NFT, a game item and a smart contract are all objects, and a transaction declares which objects it touches. When a transaction involves only objects owned by one address, such as sending coins, the network skips full consensus and confirms it in a fraction of a second. Only transactions that touch shared objects, such as a decentralised exchange pool, go through the consensus engine.

That engine is Mysticeti, introduced in 2024, which finalises transactions in well under half a second and lets validators process many in parallel. Sui's throughput in testing runs to tens of thousands of transactions per second, far beyond what any application has needed so far.

User-facing features set Sui apart. zkLogin lets someone create and control a wallet with a Google, Apple or Facebook login, with zero-knowledge proofs keeping the link private. Sponsored transactions let an app pay gas on behalf of its users. Programmable transaction blocks bundle many actions into one atomic call. The Walrus protocol, launched in 2025, adds decentralised storage for large files.

Supply and tokenomics

SUI has a fixed maximum supply of ten billion tokens. About half was allocated to a community reserve for grants, rewards and ecosystem programmes, with the remainder split among early investors, Mysten Labs and its staff, and a community access programme that sold tokens to the public at launch. Those allocations unlock on schedules that run for several years, and unlock dates are watched closely because they add supply.

Transaction fees are paid to validators and their delegators as staking rewards, and a storage fund collects a deposit for every byte stored on-chain, refundable when data is deleted, to pay validators for keeping history. Staking requires no minimum beyond one SUI, tokens can be unstaked at the next epoch, and there is no slashing. Around three quarters of circulating SUI is staked.

History and milestones

Mysten Labs raised more than 300 million dollars before launch, including a round led by FTX Ventures whose stake the bankrupt FTX estate later sold back. The mainnet opened in May 2023 and early growth came from games and NFT projects attracted by the object model. DeFi followed: the DeepBook on-chain order book, the Cetus and Bluefin exchanges, the Scallop and Navi lending markets, and Bitcoin-backed assets through partners such as Babylon.

May 2025 brought the chain's hardest moment. An exploit of Cetus drained more than 200 million dollars, and validators coordinated to freeze the attacker's funds and later return most of them through a community vote. The recovery protected users but set off a debate about decentralisation. Grayscale launched a Sui trust in 2024, and US asset managers filed for spot SUI exchange-traded funds in 2025. Sui also shipped a handheld gaming device, the SuiPlay 0X1, and signed consumer partnerships with payment and gaming companies.

What people use Sui for

Trading and DeFi lead by volume: Cetus, Bluefin and Momentum handle spot and perpetual markets, DeepBook supplies order-book liquidity to other apps, and lending protocols hold most of the chain's locked value. Stablecoins from Circle and others are issued natively, which makes Sui a cheap rail for dollar transfers.

Games and consumer apps are the second pillar and the one the founders talk about most. Titles built on Sui use object ownership for in-game items, zkLogin so players never see a seed phrase, and sponsored gas so they never buy tokens to start. Walrus storage and the SuiNS naming service round out the stack for developers.

Where to buy and trade Sui

SUI is listed on Coinbase, Binance, Kraken, OKX, Bybit, Upbit and most other large exchanges, with deep pairs against the dollar, the Korean won and major stablecoins. Exchange-traded products tracking SUI exist in Europe, and spot ETF applications progressed in the United States during 2025.

On-chain, the Sui Wallet from Mysten, Suiet and Phantom all support the network, and Ledger hardware wallets work with them. Cetus and Bluefin are the main venues for swaps. Keep a small SUI balance for gas, and when withdrawing from an exchange make sure you choose the Sui network rather than a bridged version on another chain.

Risks to understand

Sui is young, competes directly with Solana, Aptos and the Ethereum rollups, and much of its activity is still incentive-driven. Token unlocks for investors and the team add supply through 2030. The Cetus freeze showed that validators can and will intervene, which some see as protection and others as a centralisation risk.

SUI is volatile and has moved more than 50 percent in a month in both directions. Smart contract exploits, bridge failures and wallet phishing affect Sui as they do every chain. This guide is a reference for the data above, not investment advice.
