About Sui (SUI)

Layer-1 blockchain

Sui (SUI) is a Layer-1 blockchain — a base network with its own consensus, validators, and native coin (SUI) used to pay fees and secure the chain. Developers build applications directly on it, and SUI is the asset that powers the whole ecosystem.

How does Sui work?

The Sui network is maintained by a distributed set of participants who validate transactions and add them to the blockchain. SUI is required to pay for transactions and, on many networks, to stake and help secure the chain in exchange for rewards.

What is SUI used for?

SUI pays network fees, can often be staked for yield, and serves as the core unit of value across apps built on Sui. Demand for SUI tends to track activity and adoption on the network itself.

How a SUI swap works

Enter the amount you want to exchange, pick the asset on the other side, and SwapRocket queries every connected exchange partner at once. You choose an offer, paste the wallet address that should receive the funds, and send SUI to the deposit address shown. The partner executes the trade and pays out to your address — SwapRocket never holds your coins, and there is no account to create before you start.

Choosing a rate for SUI

Three offers are presented for every SUI exchange. The best rate returns the largest amount for the size you entered. The fastest route favours the partner with the shortest expected settlement time, which matters when the market is moving. The fixed rate locks the quoted amount for the duration of the order, so what you are shown is what arrives, at the cost of a slightly smaller payout. Floating offers can move with the market between deposit and settlement.

Networks and addresses for SUI

Sui settles on Sui. Always send from and to an address on that network: a deposit sent over a different chain cannot be recovered by the exchange partner. When an asset exists on several chains, pick the matching network in the widget before copying the deposit address, and send a small test amount first if you are unsure.

What is SUI? · Sourced guide · Updated 2026-09-23 · 11 sources cited

Sui replaced the account- and transaction-log model used by Bitcoin and Ethereum with an object-centric ledger, where every asset is an addressable, versioned object. Why did that specific choice, rather than a faster virtual machine or bigger blocks, become Sui's core bet, and what does it cost?

Most blockchains store state as a single ledger of account balances or a shared key-value map, updated one transaction at a time in a strict global order. Sui instead treats its entire state as a collection of discrete objects, each with its own owner and version number. That reframing lets Sui skip full network-wide consensus for transactions that only touch objects owned by one address, while still routing anything shared between multiple parties through a dedicated consensus protocol. The split is the mechanical source of Sui's low-latency claims, and it is also the reason developers cannot treat every asset on Sui the same way.

An object for every asset

In Sui's data model, global state is not one ledger keyed by account address but a set of objects, each carrying a unique ID, an explicit owner, and a version number that increments every time the object is mutated. A coin, an NFT, or a piece of application data is represented the same way: as an object that can be owned by a single address, owned by another object, or marked shared so multiple transactions can touch it.

This differs from Ethereum's model, where a contract's storage is an opaque key-value map nested inside the contract's account, and from Bitcoin's UTXO set, where individual coins are not addressable, versioned application data. Sui's documentation describes the object model as the foundation the rest of the system, including its execution and consensus design, is built on top of.^[1]

Move, extended for objects

Sui's smart contracts are written in Move, a language originally developed for Meta's Diem project. Move's original design keeps program state in global storage keyed by account, similar to other blockchain languages. Sui's variant of Move instead lets a struct become a first-class, ownable object: any struct with the `key` ability and a first field of type `UID` is treated by the runtime as a Sui object with its own identity and version.

That extension is what makes the object model programmable rather than just a storage layout. Developers reason about ownership and mutation of specific objects directly in their Move code, and the Sui documentation presents this object-centric variant of Move as a deliberate divergence from the language's original account-based semantics, made specifically to support Sui's parallel execution and ownership rules.^{[2], [3]}

Two paths to finality: owned versus shared objects

Because every object records its own owner, Sui can tell, before executing a transaction, whether it touches only objects owned by a single address. The original Sui whitepaper describes such transactions as eligible for a fast path: since no other transaction can concurrently claim the same owned objects, validators can certify the transaction without ordering it through full Byzantine fault-tolerant consensus. Transactions that touch one or more shared objects, where concurrent access is possible, are instead ordered through Sui's consensus protocol.

Sui's own consensus documentation still describes this as the structural reason simple transfers can reach sub-second finality while shared-object transactions cannot skip full consensus. The distinction is not a temporary implementation detail; it is presented as a permanent architectural feature of how Sui separates parallelizable, single-owner activity from state that genuinely requires network-wide agreement on ordering.^{[3], [4]}

Consensus evolution: Narwhal-Bullshark to Mysticeti

Sui launched using Narwhal, a DAG-based mempool, paired with Bullshark, a BFT consensus protocol built on top of it, to order shared-object transactions while the owned-object fast path bypassed that pipeline entirely. In April 2024, Sui announced Mysticeti, a DAG-based consensus protocol designed specifically for Sui, which reached mainnet in July 2024 and was reported to cut consensus commit latency to roughly 500 milliseconds in the team's own testing, with single-owner fast-path transactions measured faster still.

In November 2025, Sui published details of Mysticeti v2, which folds transaction validation directly into the consensus layer and introduces a client-side 'Transaction Driver' mechanism. Sui's blog frames this as a further step toward closing the latency and throughput gap between the fast path and full-consensus path, rather than a claim that the gap has been eliminated.^{[5], [6]}

The trade-off developers still design around

The same owned/shared split that lets Sui advertise sub-second finality for simple transfers requires application and wallet developers to think explicitly about object ownership at design time. Anything that multiple independent parties must interact with, such as an on-chain order book or shared game state, has to be modeled as a shared object, and shared objects forgo the fast path by construction, paying the latency and coordination cost of full consensus.

Sui's own consensus documentation and its Mysticeti and Mysticeti v2 posts describe narrowing that gap as ongoing engineering work rather than a solved problem. Mysticeti v2's stated goal is explicitly to make consensus-path transactions faster and lighter, which is an acknowledgment that shared-object transactions have historically lagged the fast path, not evidence that the underlying architectural split will disappear. Developers building on Sui today still have to choose, object by object, which model to accept.^{[4], [6]}

What this means when you swap SUI

A straightforward SUI transfer between two addresses is typically an owned-object transaction, and Sui's architecture documentation describes such transactions as eligible to reach finality in well under a second under normal network conditions. Even so, a swap platform crediting a deposit has reason to wait for the transaction's checkpoint, the durable, auditable commitment point described in Sui's consensus documentation, rather than relying on fast-path certification alone.

Gas on Sui is paid in SUI itself, priced by the network's computation and storage cost model rather than a fixed per-byte auction, so a wallet sending SUI onward after a swap needs to retain a small SUI balance for gas. Sui also runs in epochs of roughly 24 hours, the interval at which validator sets and staking rewards are reconciled; this does not change how fast an individual swap settles, but it explains the periodic network-wide reconfiguration events referenced on Sui status and validator pages.
