How it works
Three steps from cash to crypto
No jargon and no surprises — here is exactly what happens after you enter an amount.
- 1
Enter amount & wallet
Choose how much you want to spend, pick your coin, and paste the wallet address the crypto should land in. You see the exact rate and fee before you commit.
- 2
Pay securely
Pay with your card as a guest — no account and no identity documents. The locked rate you were quoted is the rate you pay.
- 3
Receive your crypto
Once your payment clears, we send the coins to the wallet address you entered. The address you enter is the address we pay.
Why Onexa
Honest pricing, no red tape
An on-ramp should be boring in the best way: you know the price, there is no sign-up, and the coins arrive.
Your keys stay yours
Traffic is encrypted in transit (TLS), and we never ask for your wallet keys or seed phrase — your crypto goes straight to the address you control.
Transparent fee
1%
Our fee is a flat 1% of the amount you spend, shown on the quote before you pay. Network fees, when they apply, are shown too — your rate is locked while the timer runs, so the quote is the price.
No KYC or sign-up
Buy as a guest — no account and no identity documents. Enter an amount and a wallet address, and you are ready to check out.
Multiple payment methods
Pay with Visa, Mastercard, Apple Pay, or Google Pay in the currencies we support.
Clear order updates
You'll see clear status updates for your order — when it's received, while it's verified, and when your crypto is sent.
Onexa in motion
The whole flow, in the palm of your hand
The same experience on the web app and your phone: enter an amount, watch the rate lock, and send crypto to a wallet that is yours.
Buy straight to a wallet you control
Your coins land at the address you enter — no Onexa-held balance, no custody of your keys.
Live rate locked while you check out
The price you see is held for the countdown, so what you quote is what you pay.
No KYC or sign-up
Buy as a guest — no account and no identity documents needed to buy crypto.
