Step 02

Fund with anything

Pick any held coin or token as the paying side of the trade.

Step 03

Step 04

Confirm, then hold

One confirmation of route and price, and settlement runs to your wallet, final and non-custodial from the first confirmation.

Why buy Unichain on U.CASH

Price first

The router shops every connected venue before you sign, so the quote you approve already won the comparison.

Signature economy

One approval and one swap on ERC-20 assets: no approval treadmill, no repeated prompts.

Chains are not walls

ETH moves between networks through cross-chain routes quoted with the swap itself.

Fee you can read

One flat fee on the output, stated in the quote. Nothing rides behind the number.

Your wallet is the destination

Settlement lands at addresses you control, and the keys never leave your side.

Depth on depth

Thousands of pairs reachable from ETH, from the majors down the long tail.

Before you start

Getting started takes a wallet and an address. The wallet needs to hold Unichain and a little ETH 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.

Fees and settlement

Two costs, both visible up front. The platform charges a flat 0.50% all-in on the swap and nothing hidden behind it, no spread and no routing cut. The network charges its gas in ETH, settling with about 1 sec blocks on Optimistic Rollup (OP Stack, Superchain), itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of Credited after L2 confirmation; deeper finality once the optimistic batch settles on Ethereum., and once confirmed the balance is entirely yours to move 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.

Buying Unichain: FAQ

Can I buy ETH for Unichain?
Yes. Buy ETH non-custodial and it is delivered straight to your Unichain wallet.
What can I buy Unichain with?
Any asset you already hold: the swap leg converts what you spend into ETH in one signed transaction, quoted all-in before you confirm.
Where does the ETH I buy go?
Straight to the wallet address or web3 name you provide. U.CASH never holds it; settlement is on-chain and non-custodial from the first confirmation.
Is there a minimum or maximum purchase?
No platform minimum: tokens are divisible, so any amount the network can economically settle works. Very small amounts show their network fee honestly in the preview before you decide.
