OxaPay alternative with a fiat side for USDT and USDC
OxaPay keeps the balance in crypto. If users top up USDT or USDC at fixed addresses and the money must end up in fiat, Unigox crypto processing is an OxaPay alternative. Stay with OxaPay for plugins and bitcoin.
When to stay with OxaPay
You bill through WHMCS, WooCommerce or a payment link
OxaPay has plugins for hosting and store software such as WHMCS, Blesta, WISECP and WooCommerce, plus payment and donation links, and buyers can pay in bitcoin, dogecoin, XRP or Monero. Unigox takes USDT and USDC only, on a top-up screen your own developers connect.
You want a self-serve account and a fee table
OxaPay says merchants use it without ID documents, KYC or KYB. Its pricing page publishes every fee: 1.5% to 2% per payment, plus a fixed fee on some static-address payments. OxaPay says its fees can drop to 0.4% for some businesses. Unigox crypto processing starts with a call, and its company accounts, OTC deals and Payments API need company verification.
Payments should sweep to your own wallet as they land
With auto-withdrawal on, OxaPay forwards each payment to the wallet addresses saved in your settings, and it can turn every coin into USDT first. Its payout API then sends crypto to any address within the daily limit you set, and its swap API changes one coin for another. Unigox credits your Unigox balance, and you move funds to your wallet when you choose.
From static address to balance: OxaPay and Unigox
| Topic | OxaPay | Unigox |
|---|---|---|
| Fixed address for a user | A static address per user for each coin and network, created with one API call that can carry your order ID and callback URL. Addresses with no payments for six months are revoked. | One reusable address per customer, labelled with your customer reference. The customer sends from any wallet or exchange and opens no Unigox account. |
| Coins and networks | USDT on Ethereum, Tron, BNB Smart Chain, Solana, Polygon and TON; USDC on Ethereum, BNB Smart Chain, Solana, Polygon and Base. | Crypto processing takes stablecoin payments on the major EVM networks (Ethereum, Base, Arbitrum, Polygon, Optimism, BNB Smart Chain, Avalanche, Unichain and HyperEVM), Robinhood Chain, Tron, TON and Solana. Which stablecoins a business accepts on each network is agreed during setup. |
| Fee per static-address payment | 2% plus a fixed fee: 0.46 USDT on Tron and nothing extra on its other stablecoin networks. OxaPay says its fees can come down to 0.4% depending on the business. | No public price list; priced for your company. |
| Notice to your server | A JSON callback when a payment is paying and again when paid, HMAC-signed with your merchant API key and sent up to five times until your server answers. | A notification with your customer reference and the amount that actually arrived, short or over, for your own rules to handle. |
| Euros or pounds from deposits | Not offered. OxaPay calls itself fully crypto-based and tells merchants to move funds to an exchange when they need fiat. | Deposits stay in the stablecoin sent, in your Unigox balance. Send them to your wallet, or convert them to EUR or GBP for company expenses through Unigox withdrawal services. |
| Regulation | None named. OxaPay's terms say it does not operate as a bank or financial institution, and businesses registered in the United States and several other countries may not use it. | Unigox works through two companies: UNIGOX NETWORK CORP. in Canada handles the local-money side and is registered with FINTRAC as a money services business and with the Bank of Canada as a payment service provider; UNIGOX NETWORK CORP. in Panama handles the crypto side, including wallets and escrow. |

Count your OxaPay static addresses
Bring the coins and networks your users send to OxaPay static addresses, how many addresses are active and your monthly volume. Networks, pricing and integration access are settled before launch.
Keep your order IDs
If you sent an order ID when you created each OxaPay static address, request the Unigox address for that user under the same ID. If not, use your own user ID. Show it on the top-up screen with its network and token.
Swap the callback handler
Drop the HMAC check on OxaPay's paying and paid callbacks. Handle the Unigox payment notification instead, and credit the amount it reports to the balance behind that order ID.
Questions about OxaPay alternatives
What is OxaPay, and when does Unigox fit instead?
OxaPay is a crypto payment gateway with invoices, payment links, static addresses, payouts and swaps, run with no business verification and no fiat side. Unigox fits a platform that takes USDT or USDC top-ups and needs the money in fiat.
What does the OxaPay API offer platforms with many users?
Merchant calls for invoices, white-label payments and static addresses, a payout API to crypto addresses with daily and per-payout limits, and a swap API. A static address with no payments for six months is revoked. Unigox gives each customer a reusable stablecoin address and credits your balance, which Unigox withdrawal services can turn into EUR or GBP.
What fees does OxaPay charge merchants?
1.5% on invoices and payment links, 2% on white-label payments and 2% plus a fixed fee on static addresses, which OxaPay says can drop to 0.4% depending on the business. Sending funds out on chain costs a network fee too, such as 1 USDT on Tron. Unigox prices crypto processing per company.
Can OxaPay plugins and Unigox addresses run side by side?
Yes. A WHMCS or WooCommerce checkout can keep OxaPay for bitcoin and other coins, while the USDT and USDC top-ups in your app use Unigox addresses. Your server then runs two handlers: one for OxaPay's HMAC-signed callbacks and one for Unigox notifications.
