Exchange ETH on Base for native BTC at the best instant-exchange rate. No extension, no account, BTC settles straight to the address you choose.
ETH held on Base converts to native Bitcoin in one instant-rail trade. U.CASH compares live partner offers and shows the best BTC receive amount before you commit. Send ETH from your Base address, and Bitcoin lands at the BTC address you specify, with no bridging step and no account required.
Open the pair with both sides preselected and type the amount of Ethereum you are converting. The quote for BTC updates with it, all-in, before anything is committed.
The instant-exchange network returns competing offers for the pair and the best net BTC amount is shown. The number you approve is the number that executes; there is no spread behind it.
Approve the quote and send your ETH to the displayed address. One confirmation on the way in is all the flow asks; nothing is custodial anywhere in the path.
The BTC settles on-chain to the address you chose, under 1 confirmation (fast), 3 (standard). From confirmation it is an ordinary balance: spend it, hold it, or route it on.
This pair crosses networks: the ETH leaves on EVM and the BTC arrives on Bitcoin (UTXO). 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 BTC arrives at the address you picked, settles 1 confirmation (fast), 3 (standard), and never touches a platform wallet at any point in the route.
Two things and the pair is ready. A wallet holding your ETH, and the BTC 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.
Same rails, different sides: every link opens with that pair preselected.
