CryptoPay for WHMCS

CryptoPay for WHMCS provides a complete cryptocurrency payment solution for WHMCS, allowing your customers to pay invoices using supported stablecoins directly through your existing WHMCS billing system.

The module currently supports USDC and USDT across multiple EVM-compatible blockchain networks, with an architecture designed to support additional digital assets and networks in future releases.

Payments are sent directly to your configured wallet or exchange deposit address. CryptoPay automatically monitors blockchain transactions, verifies incoming payments, tracks confirmations, and credits the corresponding WHMCS invoice when the required conditions are met.

Key Features

• USDC and USDT Payments
  Accept supported stablecoin payments directly from the WHMCS invoice and checkout process.

• Multi-Network Support
  Supports multiple EVM-compatible networks including Ethereum, Base, Polygon PoS, Arbitrum One, OP Mainnet, BNB Smart Chain, Avalanche C-Chain, and other configured supported networks.

• Direct Settlement
  Customer payments are sent directly to your configured wallet or exchange deposit address without requiring an intermediate custodial wallet.

• Automatic Blockchain Verification
  CryptoPay continuously scans supported blockchain networks and automatically detects matching transactions.

• Automatic Invoice Payment
  Once a valid blockchain transaction is detected and the required confirmations are reached, the associated WHMCS invoice can be automatically marked as paid.

• Exact Payment Amounts
  Each payment session generates an exact crypto amount to help accurately match incoming blockchain transactions with the correct WHMCS invoice.

• Real-Time Payment Status
  Customers can follow the payment process while the module checks for the blockchain transaction and required confirmations.

• Embedded Payment Experience
  The payment interface can be displayed directly inside WHMCS using a clean modal and iframe-based checkout experience without sending the customer through an unnecessarily complicated payment flow.

• Automatic Paid Confirmation
  When payment is confirmed, the payment interface can immediately display a successful payment state and update the customer experience automatically.

• Blockchain Scanner
  Administrators can manually run a blockchain scan when required in addition to automatic scheduled scanning.

• Deep Recovery Scan
  A separate recovery scan is available for locating older blockchain transactions that may require a wider historical search.

• RPC Failover
  The scanner can use fallback RPC endpoints when a blockchain provider is temporarily unavailable, rate-limited, or unable to process a request.

• Confirmation Tracking
  Configure and monitor the required blockchain confirmations before a transaction is considered complete.

• Transaction Management
  View detected blockchain transactions together with the asset, network, invoice, transaction hash, amount, confirmations, status, and date.

• Payment Session Management
  Administrators can review generated payment sessions, invoice amounts, exact crypto amounts, selected payment network, payment status, and creation date.

• Detailed Module Logs
  Built-in logs provide visibility into payment detection, blockchain scanning, RPC activity, session creation, warnings, and processing errors.

• Configurable Data Retention
  Payments, transactions, and module logs each have independent retention settings, allowing administrators to control how long historical module data is retained.

• Configurable Pagination
  Independently define how many records should be displayed per page for Payments, Transactions, and Logs.

• Network Diagnostics
  The System section provides network information, configured assets, contract details, confirmation requirements, RPC endpoints, and tools for testing RPC connectivity and token contracts.

• Checkout Branding
  Configure your own checkout logo to keep the crypto payment experience consistent with your company branding.

• Multi-Language Support
  CryptoPay includes extensive language support for international WHMCS installations.

• RTL Support
  Arabic, Persian, and other RTL interfaces are displayed with the correct text direction while blockchain addresses, transaction hashes, numerical values, and technical data remain properly formatted.

Designed for Direct Crypto Payments

CryptoPay does not require the module to hold customer funds before settlement. Payments are sent directly to the destination address configured for the selected network and asset.

The module focuses on payment detection, blockchain confirmation tracking, invoice matching, and WHMCS automation while keeping the settlement process straightforward.

Professional WHMCS Integration

CryptoPay integrates directly with the WHMCS billing workflow and provides dedicated administration pages for:

Dashboard · Payments · Transactions · Settings · Logs · System

The administration dashboard gives you a clear overview of received payments, paid invoices, pending payment sessions, recent activity, and blockchain processing status.

Future-Ready Multi-Asset Architecture

Although the current release focuses on USDC and USDT, CryptoPay is designed around a multi-asset architecture so additional supported tokens and blockchain networks can be introduced without changing the core identity or workflow of the product.

CryptoPay for WHMCS is ideal for hosting companies, SaaS providers, digital service businesses, and other WHMCS users that want to offer customers a modern cryptocurrency payment option while retaining the familiar WHMCS invoicing and automation workflow.
