One crypto payment gateway account now drops into WooCommerce, Magento 2, OpenCart, PrestaShop, WHMCS, Medusa v2 and Shopify. Every plugin carries a sandbox switch, and the WooCommerce crypto plugin runs on both the block checkout and the classic one.
Oxialink has released a full line of crypto gateway plugins for its crypto payment gateway, so a store owner can accept USDT, Bitcoin, Ethereum, TON and ten more assets without writing a line of code. Each plugin installs the way any other payment method installs, and the customer picks a coin at the checkout they already know.
Seven platforms, one API key
A single set of credentials covers 14 assets, including Tether on five networks, so a merchant does not manage one integration per coin.
The WooCommerce crypto plugin
Version 1.1.0 works on the block-based checkout and the classic checkout, and declares compatibility with High-Performance Order Storage, so it keeps working on stores that have moved off the legacy order tables. It requires WordPress 5.8, WooCommerce 6.0 and PHP 7.4.
Merchants control the order status applied after payment, the invoice expiry, a minimum order total, and a surcharge or discount multiplier for paying in crypto. Edge cases resolve on their own: an underpayment puts the order on hold with a note explaining the shortfall, and an expired invoice cancels the order rather than leaving it pending forever. No customer name, email or address is ever sent to Oxialink.
Magento 2, OpenCart and PrestaShop
The Magento 2 extension (2.3 and newer) invoices the order and moves it to processing when the payment settles. The OpenCart 3 extension and the PrestaShop module, which supports 1.7 and 8, install through each platform’s normal upload flow and let the merchant map their own order statuses. All three are MIT licensed, with no marketplace lock-in.
Medusa v2, for Node stores
The newest plugin is a payment provider module for Medusa v2, published to npm as @oxialink/medusa-payment and typed end to end in TypeScript. It registers once per coin, each instance pinned by its wallet API key, so customers choose from the payment options Medusa already renders.
WHMCS and Shopify
The WHMCS module (8.0 and newer) puts a coin picker and a Pay Now button on client invoices, which suits hosting and SaaS billing. The Shopify integration is built on the manual payment method plus order webhooks, the pattern Shopify permits for gateways outside its approved partner list.
A sandbox switch in every plugin
Every plugin has one checkbox that points it at sandbox.oxialink.com instead of production. It is the same build running against public test networks, with five assets chosen because their faucets hand out test coins in under two minutes.
That means a full order can be taken through a real checkout, paid, confirmed and completed before any money is at risk. A webhook signature that verifies in the sandbox verifies in production, because it is the same verifier.
What the plugins do after the customer pays
Every order gets its own never reused deposit address, so a payment is attributable with certainty rather than matched by amount. The customer pays on a hosted page carrying a QR code, wallet deeplinks and a live confirmation count.
When the chain confirms it, Oxialink calls the store back with an HMAC-SHA256 signed webhook that is verified byte-exactly, with replay protection, before the plugin touches the order. Behind that sits an hourly status poll for orders still awaiting payment, so a callback that never arrives cannot strand an order or a customer.
SDKs for stores that are not on a platform
Developers building their own checkout get official SDKs for PHP (oxialink/oxialink-php), Laravel (oxialink/oxialink-laravel, with an auto-registered webhook route that fires Laravel events) and Node.js (oxialink, shipping its own type definitions). All three are MIT licensed and cover invoice creation, webhook verification and withdrawals.
Pricing
Every plugin is free, and all plugin functionality is included with the free Oxialink plan. Processing is 0.5 percent per payment on the free plan and 0.2 percent on Premium at 24.99 US dollars a month, plus a fixed network fee per coin charged at what the chain costs. Figures are published on the fee schedule.
Frequently asked questions
How do I add a crypto payment gateway to WooCommerce?
Install the woocommerce crypto plugin, open a free Oxialink account, create a wallet for each coin you accept, then paste your API key, API secret and webhook secret into WooCommerce, Settings, Payments, Oxialink.
Do the crypto gateway plugins cost anything?
No. The plugins are free and Oxialink charges only the published processing fee per payment.
Which store currencies are supported?
Ten: US dollar, euro, pound sterling, yen, rupiah, rupee, Singapore dollar, ringgit, Australian dollar and Canadian dollar. A store priced outside that list is refused at checkout by name rather than quoted a wrong amount.
Can I test before going live?
Yes. Turn on sandbox mode in any plugin and the same code runs against public test networks with free faucet coins.
Where does the money go?
To an Oxialink wallet the merchant withdraws to their own address at any time, or automatically with auto-withdraw. Balances earn no interest and are not lent out.
Are there chargebacks?
No. A confirmed blockchain payment cannot be reversed by the sender, so there are no disputes, no rolling reserves and no underwriting.
