Bitcoin is the original proof-of-work blockchain and the largest cryptocurrency by market value. Payments are final, censorship-resistant, and settle peer to peer without an intermediary. On U.CASH, Bitcoin is a first-class asset: accept it, pay out to an xpub or Lightning, swap it alongside 1,500+ coins, and buy it non-custodial.

Getting started takes a wallet and an address. The wallet needs to hold Bitcoin and a little BTC 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.
The cost picture is two lines. The platform side is a flat 0.50% all-in on the swap, quoted before you sign, with no spread and no routing cut behind it. The network side is gas paid in BTC, settling with about 10 min blocks on Proof-of-Work (SHA-256), which the preview itemizes per leg. Settlement is on-chain to the address you chose: 1 confirmation (fast), 3 (standard) on this asset, after which the balance is spendable and non-custodial in the fullest sense, yours to move with no platform in the path.
Underneath, an instant integration executes the trade with all-or-nothing semantics: partial fills do not exist here, and a route unable to meet the bounds you approved reverts the whole transaction rather than settling something worse. Your exposure window between legs is therefore zero, the only cost of a failed attempt is its gas, and re-quoting is a click.
One account unlocks accept, swap, buy, and the rest of the U.CASH network across 35 networks.
