Ethereum is the leading smart-contract blockchain and the settlement layer for the largest ecosystem of tokens, DeFi, and on-chain apps. Its native asset ETH pays for computation and is the gas for every ERC-20 transfer. On U.CASH, Ethereum is first-class: accept ETH and ERC-20s, swap on the non-custodial DEX, and buy ETH, all non-custodial.

Two things and you are ready. A wallet that can hold Ethereum and a little ETH for gas on its chain, and the receiving address you want the output delivered to, which can be a raw address or a web3 name where the wallet resolves one. The preview shows the full picture before anything is signed: what leaves, what arrives, the fee, and the network cost. Nothing in the flow asks you to hand over keys; the wallet stays yours and signs only what you approved on screen.
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 ETH, settling with about 12 sec blocks on Proof-of-Stake, shown per leg before signature. Settlement runs on-chain to your chosen address at this asset's policy, 12 confirmations (standard), and from confirmation onward the balance answers to your keys alone, spendable, sendable, and settled with no platform anywhere in the path.
Execution runs through the aggregated DEX route, which means the number you approved is the number that happens or the transaction reverts: swaps are atomic, with no half-settled state to unwind and no exposure window between legs. If a route cannot fill at your approved bounds it fails cleanly and you re-quote, which is the failure mode you want, cheap and loud rather than silent and expensive.
One account unlocks accept, swap, buy, and the rest of the U.CASH network across 35 networks.
