Before you start

The setup is deliberately short. One wallet capable of holding Ink and a little ETH for gas on its chain, one receiving address for the output, and you have everything: a web3 name resolves to the address just as well as the raw string. Read the preview before signing, since it carries the whole trade at a glance, the amounts in and out, the fee, and the network cost. The wallet remains yours throughout and signs nothing you have not seen on screen, which is the whole security posture in one sentence.

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 2 sec blocks on Optimistic Rollup (OP Stack), itemized per leg in the preview. What settles is on-chain to the address you chose, under this asset's policy of Credited with a confirmation policy tuned to the optimistic rollup's fast block production., and once confirmed the balance is entirely yours to move with no platform anywhere in the path.

Underneath, the aggregated DEX route 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.

Buying Ink: FAQ

How do I buy ETH on Ink?
Choose ETH, pay with any asset you already hold, and complete it in one step. Your ETH is delivered non-custodial to your Ink wallet.
What can I buy Ink 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.
