What Is Sui (SUI)? How It Works, Tokenomics and Risks

Sui is a layer 1 blockchain developed by Mysten Labs, a company founded by former senior engineers from Meta's blockchain research division. The network is designed to process digital transactions quickly and securely using the Move programming language, while keeping fees stable even as usage grows. Its native token, SUI, is used for gas fees, staking, and governance voting.

As of October 25, 2026, SUI trades around $0.91882 according to CoinGecko, with a market cap of $3.78 billion that puts it at rank 30 by market capitalization. The price is down 63% over the past year and 19.5% over the past 30 days, well below its all-time high of $5.35 set on January 4, 2025.

The problem Sui is trying to solve

Many older layer 1 blockchains struggle to process transactions in parallel because they rely on a single account-based ledger that handles transactions one after another. When the network gets busy, fees spike and throughput drops, a scalability problem familiar to anyone who has used blockchains during peak congestion.

Sui approaches this by organizing data into independent objects rather than one shared ledger. That design lets unrelated transactions get processed at the same time instead of queuing up sequentially. Sui also targets the clunky user experience common in Web3 apps, through tools such as zkLogin, which simplifies account access, and sponsored transactions, which let people use apps without first setting up a complex wallet or covering fees themselves.

How Sui works

Instead of recording everything in one account ledger like most blockchains, Sui organizes data into separate objects. Because assets live as discrete objects rather than entries in one shared ledger, unrelated transactions can be validated at the same time instead of being processed strictly one after another. The architecture is built for rapid transaction finalization, aiming for near-instant results.

A portion of transaction fees feeds into a dedicated storage fund, which compensates validators on an ongoing basis for the cost of storing network data over time. This mechanism is meant to keep data storage costs sustainable as the network scales.

Sui is built using Move, a programming language originally developed for Meta's blockchain project (formerly known as Diem/Libra) and designed to make digital assets harder to misuse through smart contract bugs. Developers can also design custom object types that work network-wide, a feature the official description credits with encouraging deeper composability between applications.

What SUI token is used for

SUI is the primary asset for paying transaction fees and powering on-chain utility across the ecosystem, including use in decentralized exchanges and lending platforms. Holders can stake SUI to support validators and help secure the network through proof-of-stake, earning rewards in return.

SUI also carries governance rights. Token holders can vote on network rules and future protocol upgrades. Value flows through the system via a combination of staking rewards and transaction fees, which according to the official description is meant to let the platform scale sustainably.

SUI tokenomics

SUI's maximum supply is capped at 10 billion tokens, identical to its total supply, meaning there's no mechanism for minting new tokens beyond that cap. As of October 25, 2026, circulating supply stands at 4.12 billion tokens, or roughly 41% of the maximum.

The gap between SUI's market cap of $3.78 billion and its fully diluted valuation (FDV) of $9.19 billion shows about 59% of total supply is not yet in circulation. The sources we checked, including CoinGecko and the official sui.io site, don't break down token allocation across team, investors, or ecosystem funds, nor do they specify an unlock schedule. So how much of the remaining supply belongs to the team versus the community, and when it will enter the market, is not disclosed in the sources we reviewed.

Team, funding and brief history

Sui was built by Mysten Labs, a company founded by former senior engineers from Meta's blockchain research division. CoinGecko's official description cites significant institutional backing from major venture capital firms, including Andreessen Horowitz (a16z), Coinbase Ventures, Circle Ventures, and YZi Labs.

The sources we checked don't list a specific genesis date or name individual founders, so we're flagging those details as not disclosed. Sui's codebase is publicly available on GitHub under the MystenLabs organization, and the project's official account on X operates under the handle @SuiNetwork.

Market and on-chain data

As of October 25, 2026, SUI trades at $0.91882 on CoinGecko with 24-hour trading volume of $324.16 million. Its market cap of $3.78 billion ranks it 30th among all cryptocurrencies by market capitalization.

On price performance, SUI is down 19.5% over the past 30 days and 63% over the past year, well off its all-time high of $5.35 reached on January 4, 2025. On Binance Futures, the SUIUSDT contract trades at $0.91960, down 2.92% over 24 hours, with 24-hour futures trading volume of $190.2 million. Notably, the 90-day change on Binance Futures shows a 32.8% gain, contrasting with the 30-day drop of 20.9%, suggesting a rebound occurred mid-period before the recent pullback.

Funding rate on SUIUSDT is currently negative at -0.0022% per period. Funding rate is a periodic payment exchanged between long and short traders on perpetual futures contracts to keep the contract price anchored near spot price. A negative funding rate means shorts are paying longs, typically signaling selling pressure or cautious sentiment in the derivatives market.

Despite the negative funding, long account share on Binance Futures sits at 66%, meaning the majority of traders by account count are positioned long. This mismatch between bullish retail positioning and bearish funding pressure is the kind of divergence experienced traders tend to watch closely.

Open interest, the total value of futures contracts still open, stands at $100.5 million, down 40.3% over the past 30 days. A sharp drop in open interest usually signals leveraged positions being closed out or liquidated, consistent with the price correction over the same period.

Competitors

SUI risks

Only about 41% of SUI's maximum supply is currently circulating, and the sources we checked don't specify an unlock schedule for the remaining 59%. That lack of clarity is itself a risk, since large token releases down the line could add selling pressure, especially if a meaningful share sits with the team and early backers like a16z, Coinbase Ventures, Circle Ventures, and YZi Labs named in the official description.

SUI's price volatility is also notable. A 63% drop over the past year and a 19.5% drop over the past month reflect sharp swings rather than a stable, one-directional trend. In derivatives markets, open interest falling 40.3% over 30 days shows leveraged positions can shift quickly and are prone to sudden liquidations when prices move sharply.

Other general risks that apply to any layer 1 token also apply here: intense competition from rival layer 1 chains like Solana and Aptos targeting similar users, reliance on developer adoption building on Move, and regulatory risk given that crypto's legal status still varies widely across jurisdictions.

How to buy and trade SUI in Indonesia

SUI can be traded on spot markets and on futures contracts like SUIUSDT on Binance. In Indonesia, crypto asset trading is overseen by Bappebti and OJK, so transactions are best done through locally registered exchanges or global platforms with clear compliance for the Indonesian market.

For futures trading on contracts like SUIUSDT, leverage magnifies both potential gains and potential losses. With open interest having dropped sharply and funding rate in negative territory, SUI's derivatives market currently looks sensitive to sudden price swings, making risk management worth taking seriously before opening a leveraged position.

What it means for traders

A level worth watching is the $0.92 zone on the SUIUSDT contract as the current reference price, along with the persistently negative funding rate even as 66% of accounts hold long positions. That imbalance is worth tracking, since it could point to large short positions outweighing the sheer number of long accounts.

The 40.3% drop in open interest over 30 days also deserves attention. If open interest starts climbing again alongside a price rebound, that could signal fresh trading interest coming back in. If open interest keeps falling while price also weakens, that typically points to fading market interest in SUI.

Traders should also watch for official announcements from the Sui Foundation or Mysten Labs regarding token unlock schedules, since the sources reviewed here don't specify when the remaining 59% of supply will enter the market. Any such announcement, if it surfaces, could add short-term price volatility.
