Description
Let your WooCommerce customers pay in stablecoins and Bitcoin — and get paid straight to your own wallet.
- You keep full control of your funds (non-custodial). Every payment goes directly from the buyer to your own wallet address. StableDeliver never holds your money and never has your keys.
- Charges your exact order total. The buyer pays what WooCommerce calculated — quantity, coupons, tax and shipping included. There is no fixed per-product price and no surprises, and multi-item carts are fully supported.
- No percentage of your sales. StableDeliver never takes a cut of the payment itself — the crypto lands in your wallet in full.
- The order completes itself. Once the payment is confirmed on-chain, WooCommerce completes the order and releases the product through its own flow. Your fulfilment, emails and downloads work exactly as they do today.
- Try it with no money. Test mode lets you run real end-to-end orders using a test key — no chain calls, no funds — while you set everything up.
- Stablecoins and Bitcoin, on the network you choose. Accept USDT / USDC on Ethereum, Polygon, BNB Smart Chain, Arbitrum and Tron, or BTC on Bitcoin. You choose which network and asset you receive in from your StableDeliver dashboard; buyers pay in the network you configure.
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.
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 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.

Installation
- Install the plugin (upload the ZIP from Plugins → Add New → Upload, or drop it in
/wp-content/plugins/) and activate it. - In your StableDeliver dashboard, add the wallet(s) you want to receive in and choose your default receiving asset + network (Dashboard → Wallets). That is the network buyers will pay you in.
- In the StableDeliver dashboard → Settings → Developers, create an API key (start with a test key) and add this site as a webhook endpoint using the URL shown in the plugin settings. Copy the signing secret.
- In WordPress: WooCommerce → Settings → Payments, enable Pay with Crypto (USDT / USDC / BTC), click Manage, and paste your API key and webhook signing secret.
- Place a test order to confirm everything works. With a test key you can complete the order from your StableDeliver dashboard / the API
simulate_paymentcall — WooCommerce will complete the order.
Your store currency must be one StableDeliver supports (currently USD). On an unsupported currency the gateway stays hidden at checkout and shows an admin notice explaining why. Tagging a WooCommerce product with a StableDeliver product ID is optional (fulfilment linkage for your own records) and never affects the amount charged.
FAQ
-
How much is the buyer charged?
-
Your exact WooCommerce order total — quantity, coupons, tax and shipping are all included. The amount is converted to the crypto asset at the live rate when the order is created and frozen for that order.
-
Is this custodial? Do you hold my money?
-
No. Payments go straight from the buyer to your own wallet address. StableDeliver only verifies the on-chain payment and notifies your site.
-
Which coins and chains can I accept?
-
USDT and USDC on Ethereum, Polygon, BNB Smart Chain, Arbitrum and Tron; BTC on Bitcoin. You choose which network and asset you receive in from your StableDeliver dashboard.
-
Which store currencies are supported?
-
StableDeliver currently prices orders in USD. If your store uses another currency the gateway hides itself at checkout and tells you why in the admin, so a buyer is never charged the wrong amount.
-
Does it work with the Blocks checkout?
-
Yes. The gateway registers on both the classic checkout and the WooCommerce Blocks checkout.
-
Is it compatible with High-Performance Order Storage (HPOS)?
-
Yes. The plugin declares HPOS compatibility and reads/writes orders through the WooCommerce order API.
-
What happens if StableDeliver is unreachable at checkout?
-
The buyer gets a clear error and no payment is taken. The order is never silently completed.
-
How is the webhook secured?
-
Every webhook is signed with HMAC-SHA256 over the raw body and a timestamp. The plugin rejects any request with an invalid signature or an out-of-window timestamp, and de-duplicates repeated events so a retried webhook can never complete an order twice. It also confirms the paid total matches the order total before completing.

Changelog
1.1.0
- Charge the WooCommerce order total. The gateway now charges the exact order total — quantity, coupons, tax and shipping included — instead of a fixed per-product price. This corrects earlier behaviour where the charge came from a mapped product’s fixed price and could differ from the cart total.
- Multi-item carts are now supported (the previous one-item-per-order limit is removed).
- The StableDeliver product mapping is now optional (fulfilment linkage only) and never sets the price.
- The gateway hides itself at checkout when the store currency isn’t supported, with an admin notice explaining why — never a mischarge.
- Before completing an order, the plugin verifies the paid total matches the WooCommerce order total; a mismatch is held for review and never completed.
1.0.1
- Fix: align the plugin text domain with the approved plugin slug (stabledeliver-crypto-payments) so translations load correctly. No functional changes.
1.0.0
- Initial release: WooCommerce gateway (classic + Blocks checkout), HPOS compatibility, hosted checkout redirect, signed-webhook fulfilment, test mode, per-product mapping, on-chain details on the order screen.
