StableDeliver Crypto Payments for WooCommerce

StableDeliver adds a Pay with Crypto (USDT / USDC / BTC) gateway to WooCommerce.

• Non-custodial. Payments go directly to your own wallet. StableDeliver never holds funds and never has your keys.
• Verified on-chain. Each payment is confirmed on the blockchain before the order is completed.
• WooCommerce completes the order. Once the payment is verified, the plugin calls WooCommerce’s own payment_complete() — WooCommerce then completes the order and releases the product exactly as it always does. Your fulfilment workflow is unchanged.
• Classic and Blocks checkout. The gateway renders on both the classic (shortcode) checkout and the newer WooCommerce Blocks checkout.
• HPOS-ready. Compatible with WooCommerce High-Performance Order Storage (custom order tables).
• Test mode. Use a sd_test_ API key to complete real end-to-end orders with no chain calls and no money while you set things up.
• Multi-chain. USDT / USDC on Ethereum, Polygon, BNB Smart Chain, Arbitrum and Tron; BTC on Bitcoin.

The buyer pays on a hosted StableDeliver checkout, then returns to your WooCommerce order-received page. A signed webhook (HMAC-SHA256, with a 5-minute replay window) confirms the payment to your site — a forged or stale webhook can never complete an order.

You need a free StableDeliver account (https://stabledeliver.com) to get an API key.

External service

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 amount, 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.
