Buy ETH and tokens on Base non-custodial, with proceeds delivered straight to your wallet.

How to buy Base

Step 01

Open the flow

Start from the Base buy page.

Step 02

Choose how you pay

Any asset you already hold can fund the purchase.

Step 03

Give the destination

An address or a web3 name for receiving the ETH.

Step 04

Sign once

Approve route and price, and the ETH settles to that destination, final on confirmation with no platform in the path.

Why buy Base 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

The setup is deliberately short. One wallet capable of holding Base 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 seconds 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 after a few L2 confirmations, typically under a minute; deeper finality on Ethereum L1., 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 Base: FAQ

How do I buy ETH on Base?
Buy ETH on Base non-custodial and the tokens are delivered straight to your wallet. No exchange custody is involved.
What can I buy Base 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.
