About this Product

NOWPayments Crypto Gateway for WooCommerce registers a native WooCommerce payment gateway that routes checkout through the NOWPayments API, letting your store accept 300+ cryptocurrencies — including BTC, ETH and USDT — without ever touching the funds yourself. Payouts settle non-custodially, directly to your own wallet address, and NOWPayments' auto-conversion can lock the value into a stablecoin or fiat-pegged asset so you're not exposed to price swings between checkout and settlement.

This is a build-to-order plugin, not an instant marketplace download. ECOSIRE develops it against your exact WooCommerce version, installs it on your WordPress site, wires it to your NOWPayments merchant account and API keys, and supports it after go-live. You are not left to configure a generic add-on alone.

Technically, the gateway extends WC_Payment_Gateway, appears under WooCommerce → Settings → Payments, and is HPOS-compatible (it declares support for WooCommerce's high-performance custom order tables, so it works whether you run legacy post-based orders or the new order store). At checkout it creates a NOWPayments invoice/payment, redirects or embeds the pay screen, and listens on a dedicated IPN callback endpoint. Every callback is HMAC-signature-verified before any order state changes, so spoofed "paid" notifications are rejected. Order status transitions (pending → on-hold → processing/completed) are driven only by verified NOWPayments status updates, and a WP-Cron reconciliation job re-checks any payments still waiting for blockchain confirmations.

The gateway is WPML- and multisite-aware, surfaces the 0.5% NOWPayments processing fee transparently, and logs through WooCommerce → Status → Logs for clean troubleshooting. You keep custody; ECOSIRE keeps it running.

Who this is for

Volatility-averse online retailer

A WooCommerce store owner who wants to accept crypto to widen the customer base but refuses to sit on volatile coins — the auto-conversion to USDT/fiat-pegged settlement and non-custodial payout solve exactly that.

Global / cross-border merchant

A seller shipping internationally who wants a payment rail that ignores card-network geography. 300+ coins via NOWPayments lets customers pay in whatever asset they hold, with funds landing straight in the merchant's wallet.

Privacy- and custody-conscious operator

An operator who distrusts custodial processors holding their money. Non-custodial direct-to-wallet payout plus HMAC-verified IPN callbacks gives them control of funds and integrity of the paid signal without running their own node.

Frequently Asked Questions about NOWPayments Crypto Gateway for WooCommerce

Is this an instant download from WooCommerce.com or WordPress.org?

No. This is a build-to-order plugin. ECOSIRE builds it against your specific WooCommerce and WordPress versions, installs it on your site, and connects it to your NOWPayments account. There is no public marketplace download link — the deliverable is a working, configured gateway on your store.

How long does delivery take?

Typical lead time is about 5 to 10 business days from when you provide WordPress/WooCommerce admin access and your NOWPayments merchant credentials. Simple installs land at the shorter end; heavily customized checkouts, multisite, or multilingual setups take longer. ECOSIRE confirms a firm date in writing before work starts.

What ongoing support and updates do I get?

Your scope includes a post-launch support window for fixes and configuration help, plus compatibility updates so the gateway keeps working across WooCommerce and WordPress core releases. After the initial window, ongoing maintenance is available as a support retainer. The IPN signature verification and order-status logic are kept aligned with NOWPayments' current API.

Does ECOSIRE or NOWPayments ever hold my money?

No. Settlement is non-custodial — payouts go directly to the wallet address tied to your own NOWPayments merchant account. ECOSIRE never has access to your funds. The plugin only orchestrates invoice creation, callback verification and WooCommerce order updates.

Is it compatible with HPOS, WPML and multisite?

Yes. The gateway declares compatibility with WooCommerce High-Performance Order Storage (custom order tables) and also works with legacy post-based orders. Checkout labels and emails are WPML/multilingual-aware, and it runs on WordPress multisite networks. ECOSIRE confirms the exact matrix against your environment during scoping.
