Swap Sui (SUI)

Swap Sui through the instant-exchange network: SUI against BTC, ETH, USDT and 1,500+ assets, or any asset into SUI, settled to the wallet address you provide.

How Sui swaps on U.CASH

Sui swaps on the U.CASH instant-exchange network, which reaches assets the EVM DEXs can't. The output settles to the wallet address you provide. For EVM and Solana assets, the same screen routes through the non-custodial DEX instead.

Before you start

Getting started takes a wallet and an address. The wallet needs to hold Sui and a little SUI for gas on its chain; the address is where the output lands, raw hex or a resolvable web3 name both work. From there the flow is preview-first: what leaves, what arrives, the fee, and the network cost all sit on one screen before a signature happens. Keys never leave your side at any point, and the only thing the wallet ever signs is the exact transaction you read.

Fees and settlement

Count the costs on one hand. On the platform side a flat 0.50% covers the swap, all-in, stated in the quote with no spread or routing cut behind the number. On the network side, gas in SUI, settling with about 1 s finality blocks on Mysticeti delegated proof-of-stake, shown per leg before signature. Settlement runs on-chain to your chosen address at this asset's policy, Near-instant single-slot finality, and from confirmation onward the balance answers to your keys alone, spendable, sendable, and settled with no platform anywhere in the path.

The route runs on an instant integration, and atomicity is the property that matters: the approved number either happens in full or the transaction reverts with nothing moved but the attempt's gas. There is no resting state between legs where value sits in someone else's hands, and a route that misses your bounds simply fails clean, ready for a fresh quote. Cheap and loud beats silent and expensive as failure modes go.

Swapping Sui: FAQ

How do I swap SUI?
Open swap.u.cash/sui and the pair arrives prefilled. Pick what you want to receive, confirm the route, and the output settles to the wallet address you provide.
Is a SUI swap non-custodial?
The instant-exchange partners handle the trade leg and the output settles on-chain to the address you provide. U.CASH never holds your output.
What does swapping Sui cost?
A flat 0.50% all-in on the swap plus the network gas, both shown in the quote before you sign. No spread, no routing cut, no settlement surprise.
How fast does a Sui swap settle?
At the chain's pace: ~1 s finality blocks on Mysticeti delegated proof-of-stake, with the platform acting on the stated confirmation policy. The preview shows the expectation with the quote.
Can I swap Sui cross-chain?
Yes: routes that cross networks are quoted alongside same-chain ones, and where Sui exists on several chains the engine moves between its native forms through liquidity rather than pooled custody.
