The "Pay with Crypto (USDT / USDC / BTC)" option at EDD checkout.
Let your Easy Digital Downloads 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 EDD success page. You need a free StableDeliver account (https://stabledeliver.com) to get an API key.
Under the hood: payments are 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 a payment. Before a payment completes, the plugin also checks the paid total against the EDD 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 EDD payment 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.
