GrineoPay Crypto Gateway with Instant Payouts

FAQ

Do I need a GrineoPay account before using this plugin?

Yes. You must create or access a GrineoPay merchant account before using the plugin.

Login here:
https://grineopay.com/login

You will need your merchant crypto credentials and active wallet configuration from GrineoPay in order to complete setup.

What are the available payment methods?

This plugin is a crypto-only payment gateway.

Customers pay directly using supported cryptocurrencies from their own wallet. The plugin does not process card payments, debit cards, Apple Pay, or Google Pay.

What cryptocurrencies are supported?

Supported options include:
* BTC
* ETH
* SOL
* LTC
* XMR
* DOGE
* ADA
* TRX
* USDT on supported networks
* USDC on supported networks

The exact list shown at checkout depends on:
1. the gateway settings, and
2. the merchant’s active wallets configured on GrineoPay

If only Bitcoin is visible, check:
* the merchant has saved all desired wallets in the GrineoPay dashboard
* the selected enabled assets include those coins/networks
* the GrineoPay remote API is returning those wallets

How quickly do wallet changes reflect on checkout?

This plugin is configured to fetch wallet-backed assets fresh from GrineoPay with no persistent transient caching by default, so wallet additions or removals should reflect on the next checkout reload.

Because the WooCommerce store is separate from the GrineoPay platform, checkout visibility depends on the latest wallet-backed asset response from the remote GrineoPay API.

What is the minimum order amount?

The minimum order amount is configurable by the merchant in the WooCommerce payment gateway settings.

If the cart total is below that configured minimum, GrineoPay will be hidden at checkout.

Set the minimum to 0 if you want GrineoPay to always be visible regardless of cart total.

What is the maximum order amount?

There is no single universal fixed maximum in the plugin itself.

Practical limits may depend on:
* blockchain conditions
* wallet capabilities
* supported assets
* remote payment provider constraints
* risk and operational controls

How does settlement work?

GrineoPay settles in the original cryptocurrency paid by the customer.

If a customer pays in BTC, the merchant receives BTC.
If a customer pays in ETH, the merchant receives ETH.

This is designed for merchants who want original-coin settlement rather than automatic fiat conversion.

What payout wallet do I need?

You need a wallet that supports the cryptocurrencies and blockchain networks you want to accept through GrineoPay.

Because the merchant receives the original coin paid by the customer, the merchant must configure wallet addresses that match the enabled crypto asset/network combinations. We support payouts in BTC, ETH, SOL, LTC, XMR, DOGE, ADA, TRX, USDT on supported networks, USDC on supported networks

What are the processing fees?

Processing fee is 0.5% per transaction. No subscriptions. No hidden fees.

Which countries are supported?

GrineoPay supports merchants and customers in most countries worldwide, excluding restricted jurisdictions.

Is GrineoPay custodial?

The checkout flow is designed to be non-custodial in customer experience terms, with wallet-based payment handling and direct merchant payout routing based on configured wallets.

Do users need KYB or KYC?

Because GrineoPay’s crypto checkout flow is 100% non-custodial, we do not require KYB or KYC.

How quickly can I access my funds?

Timing depends on:
* the blockchain network
* confirmation timing
* transaction conditions
* the GrineoPay payment routing flow

The plugin itself is designed for instant payout routing logic, but practical timing always depends on actual network confirmation and remote platform processing.

How secure is GrineoPay’s payment system?

This plugin is built around:
* webhook signature verification
* remote wallet-backed asset validation
* checkout-level crypto selection validation
* secure remote API communication
* credential sanitization
* WooCommerce-safe order state handling

How do I integrate GrineoPay with my store?

Install and activate the plugin, create your GrineoPay account, configure your wallets, add your API credentials in WooCommerce, and connect the webhook URL shown in the settings.

Then test checkout using a supported cryptocurrency.

What happens if a customer’s payment fails?

If the remote payment does not complete successfully, the WooCommerce order remains unpaid or is marked failed depending on the webhook status returned by GrineoPay.

What businesses does GrineoPay support?

GrineoPay supports a range of merchant categories depending on its current policies, supported countries, and risk criteria.
