What it is

The fastest way into UCASH

U.CASH Buy is two rails into UCASH. The fiat ramp turns card, bank transfer, Apple Pay, or Google Pay into crypto in 40+ fiat currencies, and the UCASH-locked Buy DEX delivers UCASH at the live market rate. It is non-custodial: every payout lands directly in your own wallet.

How it works

Card or bank into crypto

Pick currency and crypto

Choose your fiat and what you buy: UCASH, BTC, ETH, and more, across 40+ fiat currencies.

Enter your payout address

Crypto pays out directly to your own wallet. U.CASH never holds it.

Pay by card or bank

Card, bank transfer, Apple Pay, or Google Pay. KYC, where required, is handled at checkout.

Your crypto lands

The purchase settles and the payout arrives at the address you provided, on the chain you chose.

Paying with crypto instead?

The UCASH-locked Buy DEX swaps crypto you already hold into UCASH at market price; the any-token input flow lives at get.u.cash.

Capabilities

What U.CASH Buy can do

Non-custodial, wallet-to-wallet

U.CASH never holds your funds. DEX trades are signed and sent from your own wallet, and ramp payouts go straight to the address you provide.

One-step Permit2 approvals

ERC-20 sells on the DEX use Permit2: you sign a gasless off-chain EIP-712 message that authorizes the settler, collapsing the usual approve-plus-swap into a single on-chain transaction.

Card, bank, Apple Pay, Google Pay

The fiat ramp takes 40+ fiat currencies into crypto, with KYC handled at checkout where required. Payouts go straight to your wallet.

Best-route aggregation

Same-chain quotes scan the DEX aggregator liquidity across venues and show the split route; cross-chain routes are ordered cheapest-first through cross-chain bridges to deliver the most UCASH for your input.

Full transparency before confirm

The route panel shows the UCASH you receive, the minimum after slippage, the live rate, routed venues, estimated network fee, and the 0.30% swap fee in UCASH.

WalletConnect v2 and mobile

Connect MetaMask, Rabby, or Brave directly when an injected wallet is present, or scan a WalletConnect v2 QR code to trade from any mobile or external wallet.

Buy and bridge in one tx

Buying on Ethereum can deliver UCASH on Base or Polygon directly through the bridge router, so one transaction both swaps and bridges to the chain you want.

How it fits in U.CASH

Buy and the rest of the network

Buy is the fiat front door to UCASH; it shares the Swap rails and the U Account.

What can I pay with?
Card, bank transfer, Apple Pay, or Google Pay in 40+ fiat currencies on the fiat ramp, or crypto you already hold on the UCASH-locked Buy DEX. KYC, where required, is handled at checkout.
What is the fee?
Ramp quotes show the full rate before you pay. DEX buys take the same 0.50% all-in swap fee as swap.u.cash (0.35% U.CASH plus a 0.15% partner routing fee), shown on the route panel before you confirm, alongside the estimated network gas fee.
Paying with crypto instead?
The UCASH-with-any-token flow lives at get.u.cash: pay from 20 chains with Permit2 one-step delivery. buy.u.cash keeps the fiat ramp and the UCASH-locked Buy DEX.
Which chains does UCASH live on?
UCASH is native to Ethereum, Polygon, and Base. Ramp payouts arrive on the chain you choose, and a DEX buy can deliver UCASH on Base or Polygon directly by bridging in the same transaction.
