The plugin depends on the API of the payment provider SecPay (https://www.secpay.io). After the onboarding you’ll be able to accept Bitcoin payments in your store, while the payout will be automated in EUR to your SEPA bank account. To use this plugin you need a secpay.io account. For testing purposes you can request that for free at email@example.com. For production please contact firstname.lastname@example.org to provide you the terms and credentials.
