What is Sui?

How does Sui work?
Sui represents assets as objects with identifiers, ownership and versions, rather than only account balances. Validators selected through delegated proof of stake agree on accepted transactions and execute their effects. Move programs define asset rules, but using Move does not make every application or transaction safe.

Who created Sui?
Sui originated with the team at Mysten Labs, whose official founders page names people including Evan Cheng and Adeniyi Abiodun. It is maintained through a wider network of developers and validators. SUI is a blockchain asset, not equity in Mysten Labs or a guaranteed claim on its products.

What is Sui used for?
SUI pays for computation and storage when users transfer assets or interact with Sui applications. It also supports delegated staking and network governance. Sui's object model enables programmable assets such as game items, but holding SUI does not guarantee benefits from any particular game or application.
Where can you buy Sui?
Check the chosen platform's official website for current SUI availability and your account's eligibility. For self-custody, verify support for withdrawals of native SUI to Sui mainnet. A SUI symbol on another blockchain can represent a different or bridged asset, not an interchangeable native balance.

How to buy Sui
Plan your purchaseHow much Sui?
How can you buy Sui safely?
Verify the platform and wallet through their official websites, then confirm the asset is native SUI and the withdrawal network is Sui mainnet. Review minimums and charges before testing a small transfer. Never disclose a wallet recovery phrase to a seller, support account or purported token-claim page.
Can you buy a fraction of Sui?
Yes, SUI is divisible into one billion mist per coin, so a whole SUI is not required. Purchase platforms can still impose minimum order or withdrawal amounts. Keep an appropriate spendable SUI balance for gas; the wallet's quoted budget can differ from the final net charge.
How much does it cost to buy Sui?
The minimum practical SUI purchase depends on the platform's order size, spread, payment costs and withdrawal minimum. Native Sui transactions also charge for computation and storage, with potential storage rebates. Review the total cost of obtaining usable SUI in your own wallet rather than only the trade price.
How much is one Sui worth?
SUI is denominated in MIST, with one billion MIST per SUI. A transaction gas budget is a spending limit for execution, not a market quote for those coins; computation, storage charges and eligible storage rebates affect the final network cost. For a purchase, use a recent SUI quote as context and verify the provider's coin quantity and total charge. Do not equate an application's maximum gas budget with the price of acquiring SUI.
Is Sui a good investment?
SUI is a volatile asset, and neither its supply cap nor native staking makes it a safe investment. Unlock schedules, validator behavior, application exploits and custody failures remain relevant. No purchase size, including $500, universally limits those risks. This is not financial advice.
Compare two order previews
Use SUI credited after buying fees and spread. Extra USD charges must exclude fees already included in the total. Enter 0 only when confirmed.
Which quote delivers more SUI?
Enter your order-preview numbers or use the labeled example. Unknown charges are never treated as zero.
Sui wallets & storage
How do you get a Sui wallet?
Use a wallet that explicitly supports Sui mainnet and decide which recovery model you understand. For example, Slush documents both passphrase and social-login account creation, which require different access safeguards. Confirm the network and receiving address before funding the wallet, and keep recovery credentials private.
How can you store Sui securely?
Secure the access method actually controlling your Sui address, whether recovery phrase, hardware device or supported social login. For phrase accounts, anyone obtaining the phrase can spend the assets; social-login access depends on the relevant credentials and recovery flow. Review transaction requests, not just wallet-connection prompts.
Sending & cashing out Sui
Match your networks
For SUI, copy the exact network names shown in your apps. This compares your entries, not a verified list of supported networks.
Enter both network names
Copy the exact network name shown for this asset in each app. No supported-network catalogue is assumed here.
How do you send Sui to another wallet?
In a Sui-compatible wallet, select native SUI, verify the recipient's Sui mainnet address and review the transaction's gas budget. Do not confuse an application's token with the SUI gas coin. After sending, inspect the successful transaction effects and confirm that the recipient can see the intended balance.
How long does a Sui transfer take?
Sui finalizes accepted transactions through its validator protocol, but wallet submission and an exchange's account credit are separate events. A rejected or aborted transaction is not a completed payment. Network conditions, client connectivity and platform processing can affect availability, so there is no universal guaranteed arrival time.

How much does it cost to send Sui?
Sui charges gas in SUI for computation and storage, with a network reference computation price set by epoch. Deleting eligible stored objects can return part of a storage charge. Use the wallet's current estimate for the exact transaction; a gas budget is a spending limit, not necessarily the amount ultimately charged.
Can you cash out Sui for real money?
Confirm that a platform legally available to you currently accepts native SUI deposits on Sui mainnet and offers the fiat payout you need. Follow its deposit instructions and test the route before a larger transfer. Staked SUI or liquid-staking tokens may require additional actions before becoming an accepted liquid deposit.
Is Sui traceable?
Sui's object history records identifiers, owners, versions and transaction references, so standard activity is not inherently anonymous. Observers can follow asset changes and link addresses using outside information. A social-login wallet changes authentication, not the default visibility of its on-chain transfers or objects.
Supply, mining & staking
What is the maximum supply of Sui?
SUI has a maximum supply of 10 billion coins under the documented mainnet design. That maximum is not the same as circulating supply: allocations become available through unlock schedules, while staking and storage funds also affect availability. Protocol staking subsidies are drawn within that supply design, not unlimited mining.
Can you mine Sui?
SUI is not a proof-of-work mining coin. Its network uses delegated proof of stake, with validators processing transactions and earning protocol rewards. An ordinary full node or a website advertising cloud mining does not itself provide native SUI issuance rights.
Can you stake Sui?
Yes, native SUI staking delegates coins to a validator and represents the position with a self-custodial stake object. Activation, eligible reward periods and withdrawals depend on epoch rules. Validator commission and performance affect rewards; a separate liquid-staking application adds its own contract and token risks.
