Sui: Swaps, Lending, Payments and Data Storage

Sui is an independent blockchain with Move smart contracts. Its applications offer swaps, liquidity, lending and payments. SUI pays for standard transactions and participates in validator staking. A sponsor can also cover gas, while an eligible stablecoin transfer can execute without a network payment in SUI.

SUI, coin types and application objects

Sui represents assets and application state through Move. A coin has a full type, while an object has an identifier and ownership rules.

SUI

Network payment and delegation

SUI is the network’s native coin. Standard transactions spend SUI on computation and storage. Holders can delegate part of their balance to a selected validator.

COIN

A specific token issue

A coin type includes its package address, module and type name. It distinguishes assets sharing a ticker. Circle’s USDC has its own Sui type; moving an asset with that name from another network requires a separate route.

OBJECT

Who can use the state

An object can be address-owned, shared by application participants or immutable. A shared object lets multiple users access the same state, such as a trading market. Its Move program determines permitted actions.

Transaction payment

Your SUI, a sponsor’s SUI or a gasless transfer

A standard transaction uses the payer’s SUI. Sponsorship assigns that cost to another participant. Gasless transfers are a separate protocol feature for eligible stablecoins and supported balance operations.

Pay with my SUI

  1. WalletAction and spending cap

    The user signs a transfer or application call with a gas budget limiting network expenditure.

  2. SUIPayment from the user

    The wallet provides SUI for fees. Actual cost accounts for computation, storage and rebates for deleted data.

  3. NetworkState update

    Sui executes the action and records the transfer, swap or application position change.

This route handles standard SUI transfers and application calls. The gas budget caps payment; the executed transaction determines the final fee.

A sponsor covers gas

  1. ActionThe user selects an operation

    The application prepares a supported action involving the user’s assets or data.

  2. SponsorAnother payer provides SUI

    The sponsor supplies SUI and payment terms. The user and sponsor sign the same transaction.

  3. NetworkExecution with sponsored payment

    Sui verifies both signatures and charges the designated sponsor’s gas payment.

An application can cover selected user actions without SUI in the user’s wallet. The paying service determines sponsorship availability and permitted operations.

Transfer a stablecoin without gas

  1. AssetA protocol-allowlisted stablecoin

    The sender uses an eligible stablecoin type and transfers at least 0.01 units.

  2. TransferA permitted balance operation

    The wallet constructs a supported transfer without writing objects. Its gas price and gas budget are zero.

  3. RecipientStablecoin in the receiving balance

    The transfer executes without the sender’s SUI and without a sponsor payment.

The feature covers eligible stablecoin transfers, including the supported USDC type. Swaps, NFT creation and SUI transfers use standard payment or separate sponsorship. During congestion, the network prioritizes transactions that pay gas.

Swaps, lending, trading markets and data

Swap pools, lending markets and order books use assets in different ways. Walrus serves a separate purpose: its nodes store files, while Sui coordinates payments and storage records.

Swaps and range-based liquidity

Cetus

Cetus uses concentrated-liquidity pools: suppliers choose a price range for each position. One pool can contain several positions with independent ranges, and swaps use the liquidity available within them.

Open application ↗ Documentation ↗

Deposits and borrowing

NAVI

Assets supplied to NAVI enter lending pools and earn interest under their terms. Borrowing uses collateral; the available amount and parameters belong to the selected asset market.

Open application ↗ Documentation ↗

Spot and derivatives

Bluefin

Bluefin combines spot trading and derivatives on a platform built on Sui. The platform is unavailable to US residents.

An onchain order book

DeepBook

DeepBook stores and matches orders in Sui contracts. Trading interfaces can use its markets and balance management to execute trades; opposing orders determine price and available size.

Open application ↗ Documentation ↗

File storage

Walrus

Walrus stores files as immutable blobs across distributed storage nodes. Sui objects link them to payments, metadata and storage duration. Changing a file produces a new content identifier.

Open application ↗ Documentation ↗

Receive the asset on Sui

An exchange withdrawal selects the destination network. SUI and application tokens need a Sui-compatible wallet; standard actions also require SUI for network fees.

01

Select the Sui network

Open the receiving address in a Sui wallet and select Sui at the sending service. Other networks also use addresses beginning with 0x; the withdrawal network determines where the asset arrives.

02

Fund the required asset

Receive SUI or the token accepted by the selected application. A stablecoin deposit needs the correct full coin type. Keep separate SUI for a standard swap or lending action.

03

Select how the action is paid

The wallet displays the operation, payer and gas budget. A supported application can sponsor gas; an eligible stablecoin transfer can use the separate zero-gas-payment route.

Delegate SUI to a validator

Native staking selects a validator and allocates SUI to its stake. The network accounts for stake and distributes rewards by epoch, the period for which a validator committee operates.

01

Select and delegate

A wallet or explorer shows validator details and commission. Staking creates an object you own that records the chosen pool and activation epoch.

02

Accrue epoch rewards

Rewards accrue for epochs in which the stake is active for the entire period. Validator performance and commission affect the amount. Pool accounting determines the SUI and rewards available on withdrawal.

03

Withdraw the coins

Unstaking redeems the stake object and returns the original SUI together with accumulated rewards. Changing validators requires withdrawing the previous stake and delegating again.

Computation, storage and partial rebates

Standard network fees pay for execution and data storage. Deleting previously stored objects returns part of their storage charge. A user’s gas budget, a sponsor’s expenditure and an application’s trading fee refer to different payments.

Practical questions

1Why is the gas budget larger than the final fee?

The budget caps permitted spending. The actual fee follows computation and data writes, while rebates for deleted objects reduce the net charge. The unused part of the budget does not become a fee.

2Is a coin type a wallet address?

A wallet address identifies the recipient. A coin type identifies the specific asset and includes a Move package, module and type name. One address can hold several coin types.

3Does unstaked SUI in a wallet earn staking rewards?

Rewards accrue to SUI allocated to a validator’s stake and active for a full epoch. A freely available wallet balance can fund transfers and applications; holding it alone does not create a staking position.
