Exchange BTC for SUI at the best instant-exchange rate. No wallet extension, no account, SUI settles straight to the address you choose.
BTC to SUI moves Bitcoin into Sui in one trade. U.CASH compares live partner offers and shows the best SUI receive amount before you commit. Send Bitcoin to the deposit address, and SUI arrives at the Sui address you specify, with no account and no extension required.
Two things and the pair is ready. A wallet holding your BTC, and the SUI address you want the output delivered to, raw string or web3 name where your wallet resolves one. The preview shows the whole trade before anything is signed: what leaves, what arrives, the fee, and the network costs. Keys never leave your side at any point in the flow.
Open the pair with both sides preselected and type the amount of Bitcoin you are converting. The quote for SUI updates with it, all-in, before anything is committed.
The instant-exchange network returns competing offers for the pair and the best net SUI amount is shown. The number you approve is the number that executes; there is no spread behind it.
Approve the quote and send your BTC to the displayed address. One confirmation on the way in is all the flow asks; nothing is custodial anywhere in the path.
The SUI settles on-chain to the address you chose, under Near-instant single-slot finality. From confirmation it is an ordinary balance: spend it, hold it, or route it on.
This pair crosses networks: the BTC leaves on Bitcoin (UTXO) and the SUI arrives on Layer 1. The instant-exchange network handles both legs as one quoted trade, so the crossing is priced into the offer you approve rather than added after the fact.
Count it on one hand: 0.50% flat to the platform, stated in the quote with nothing behind it, plus each chain's gas for its leg of the trip. The route runs non-custodial end to end, so when the SUI settles Near-instant single-slot finality at your address, it is yours in the fullest sense: no custodian, no withdrawal queue, no platform in the path.
Same rails, different sides: every link opens with that pair preselected.
