Exchange BTC for WBTC at the best instant-exchange rate. No wallet extension, no account, WBTC settles straight to the address you choose.
BTC to WBTC moves Bitcoin into Wrapped Bitcoin in one trade. U.CASH compares live partner offers and shows the best WBTC receive amount before you commit. Send Bitcoin to the deposit address, and WBTC arrives at an Ethereum address (0x…), with no account and no extension required.
Open the pair with both sides preselected and type the amount of Bitcoin you are converting. The quote for WBTC updates with it, all-in, before anything is committed.
The instant-exchange network returns competing offers for the pair and the best net WBTC 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 WBTC settles on-chain to the address you chose, under Follows Ethereum (~12 confirmations). 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 WBTC arrives on EVM. 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.
Two costs, both on the screen before you sign: the flat 0.50% platform fee on the swap, and the networks' own gas for the movement. What you approve is what executes. The WBTC arrives at the address you picked, settles Follows Ethereum (~12 confirmations), and never touches a platform wallet at any point in the route.
The setup is short by design: one wallet capable of holding BTC, one receiving address for the WBTC, and nothing else. Read the preview before signing, since it carries the entire trade at a glance, the amounts in and out with the fee and network costs included. The wallet stays yours throughout and signs only the transaction you read on screen.
Same rails, different sides: every link opens with that pair preselected.
