The "Pay with Crypto (USDT / USDC / BTC)" option at WooCommerce checkout.
Let your WooCommerce customers pay in stablecoins and Bitcoin — and get paid straight to your own wallet.
Buyers pay on a secure StableDeliver checkout and return to your WooCommerce order-received page. You need a free StableDeliver account (https://stabledeliver.com) to get an API key.
Under the hood: the gateway works on both the classic and WooCommerce Blocks checkout, is compatible with High-Performance Order Storage (HPOS), and is confirmed to your site by a webhook signed with HMAC-SHA256 (with anti-replay and de-duplication) — a forged, stale or duplicated webhook can never complete an order. Before an order completes, the plugin also checks the paid total against the WooCommerce order total and holds any mismatch for review rather than completing it.
This plugin connects to StableDeliver (https://stabledeliver.com), an external service, to create payment orders and verify cryptocurrency payments on-chain. StableDeliver performs the substantive work of this gateway: it confirms the exact on-chain transfer to the seller’s own wallet (non-custodial settlement) and, once verified, triggers fulfilment on your site via a signed webhook.
What is sent, and when: when a buyer chooses crypto at checkout, the plugin sends the order total, currency and an order reference (your WooCommerce order ID) to the StableDeliver API to create a checkout. It then receives a signed webhook when the payment is verified. No customer payment credentials, card numbers, private keys or seed phrases are handled by this plugin.
