Our verdict on xSui
6.0/10xSUI suits Sui holders who want staking rewards without locking their SUI and who are comfortable using a newer protocol. Its main strength is a simple liquid staking model tied into Momentum's wider DeFi suite. The main caveat is the lack of listed audits, unpublished fee details and a small TVL of around $199,000, which raises smart-contract and liquidity risk. Read the documentation first and size positions cautiously.

What is xSui?
xSUI is the liquid staking token from Momentum Finance, a DeFi platform on Sui. Users stake SUI and receive xSUI, which keeps accruing staking rewards and can still be used across DeFi.
Momentum describes itself as a Move-based central liquidity engine, with xSUI sitting next to a DEX, Vaults, veMMT, a portfolio dashboard and a bridge. Third-party write-ups also mention MSafe multi-signature wallets and token launch tools as part of the wider ecosystem.
The tracked listing shows about $199,000 in TVL, listed since July 2025, with no audits recorded and no separate token for xSUI.
How xSui works
When you stake SUI through Momentum, the protocol issues xSUI in return. xSUI represents your staked SUI and the rewards it earns, so its value is tied to the underlying staking position rather than staying a fixed 1:1 count.
Because xSUI is a normal token on Sui, it can be held, traded or deposited in other DeFi protocols while the underlying SUI keeps earning. This is the standard liquid staking idea: you avoid locking capital while still receiving staking yield.
Momentum positions xSUI as one part of a broader suite that also includes a trading and liquidity engine, Vaults, veMMT and a bridge. How validators are chosen and how redemption works are not detailed.

Pros and cons
What we like
- Keeps staked SUI liquid, so capital is not locked while earning rewards.
- Rewards accrue to the token, which is simple to hold.
- Integrated with Momentum's other products such as Vaults and trading.
- Usable across other DeFi protocols on Sui.
- Operates on a single chain, which keeps the model easy to follow.
Watch out for
- Small TVL of roughly $199,000 on the tracked listing, so liquidity for xSUI may be thin.
- No audits are listed for xSUI in the tracked data.
- Exposure to smart-contract risk on top of the base staking risk on Sui.
- Fee levels, validator selection and unstaking terms are not stated.
- Reliant on the wider Momentum platform, so xSUI risk is tied to that protocol's contracts and governance.
- Rewards are variable and depend on Sui network staking returns.
xSui fees
Public sources do not publish xSUI fee details, such as any share of staking rewards taken by the protocol or unstaking charges. Users would see these in the Momentum app's xSUI section and in the project documentation before staking.
Standard Sui network gas fees apply to any transaction. Swapping xSUI on a DEX would also involve that venue's trading fees and possible slippage.
Is xSui safe?
No audits are listed for xSUI in the tracked data, and public sources do not name audit firms or publish a bug bounty. Treat the contracts as unverified until you have read the project's own security documentation.
Liquid staking adds smart-contract risk on top of the base staking risk, and xSUI can trade at a discount to SUI if liquidity is thin. The small TVL makes that discount risk more relevant. Only stake amounts you can afford to lose.
