GrineoPay Crypto Gateway with Instant Payouts

GrineoPay Crypto Gateway with Instant Payouts lets merchants accept cryptocurrency payments directly on their store using supported crypto assets and networks routed through GrineoPay.

This plugin is built for merchants who want a crypto-only payment solution with a non-custodial checkout experience, wallet-based payments, and instant payout routing logic through the GrineoPay ecosystem.

With this plugin, customers can select supported cryptocurrencies during checkout and complete payment using their own wallet, while merchants receive the original cryptocurrency paid by the customer based on their configured GrineoPay wallet setup.

Wallet-Based Crypto Visibility

This plugin only shows crypto methods at checkout when they are actually payout-ready.

A crypto option appears only if:

1. it is enabled in the WooCommerce gateway settings, and

2. the merchant has an active matching wallet configured in GrineoPay for that exact crypto/network combination

This helps prevent customers from choosing unavailable crypto methods and ensures checkout stays synchronized with the merchant’s GrineoPay wallet configuration.

• Fast reflection of merchant wallet changes on checkout

• Support for WooCommerce subscriptions compatibility flags

• Admin order crypto metadata display

• Debug panel for wallet visibility, credentials, and minimum order diagnostics

* Secure webhook signature verification

* Crypto checkout backed by merchant wallet validation

* Server-side validation for crypto asset availability

* Automatic sanitization of stored API credentials to prevent silent authentication failures caused by hidden or invisible characters

* Non-custodial customer payment flow

* Fully GPL-compatible and WooCommerce-friendly
