SHKeeper is a self-hosted, open-source cryptocurrency payment processor that combines gateway and merchant functionality. It lets merchants accept direct crypto payments to their own wallets using an invoice-based API and callback system.

Key Features

  • Non-custodial architecture: merchants control their private keys and wallets with optional wallet encryption.
  • Multi-currency support: supports many coins and tokens (BTC, ETH, LTC, DOGE, XMR, XRP, TRX, BNB, SOL, MATIC, AVAX, USDT, USDC and others across multiple networks).
  • Invoice-based workflow: unique invoice per order maps to a generated address; supports UNPAID, PARTIAL, PAID, and OVERPAID statuses.
  • REST API and API key authentication for creating invoices, querying balances, and managing payouts.
  • Webhook/callback notifications for transaction and invoice status updates.
  • Payout and multipayout capabilities, with options for auto-withdrawal to cold wallets.
  • Integrations and ready-made modules for common platforms (examples include WooCommerce and WHMCS) and embeddable payment buttons/QR codes.
  • Static address mode pattern for reusable deposit addresses per customer.
  • Admin UI and dashboard for wallet management, metrics, and configuration.
  • Kubernetes/Helm and container-friendly deployment; supports running with external public nodes to reduce local resource needs.

Use Cases

  • Accept cryptocurrency payments in an e-commerce checkout or CMS plugin using invoice creation and callbacks.
  • Operate a merchant-facing gateway to receive direct deposits and manage payouts to cold wallets.
  • Run a private crypto payment processor for hosting providers, marketplaces, or subscription services that require multi-coin support.

Limitations and Considerations

  • Full node requirements: some networks (notably Ethereum, BNB, Tron and others) may require full nodes with significant CPU, RAM and disk resources unless external/public nodes are used.
  • Operational complexity: production deployment requires secure key management, node operation or reliance on external nodes, and attention to backup and monitoring.

SHKeeper is aimed at teams that need direct control over crypto payment processing and are able to manage node infrastructure or accept the operational trade-offs of using external nodes. It provides a feature-rich, API-driven gateway and admin UI for merchants who want non-custodial, multi-coin payment acceptance.

DePay is a JavaScript SDK and set of embeddable widgets that let websites and apps accept crypto payments directly into merchant wallets. It handles wallet selection, token routing and on-the-fly conversions so a single integration can accept many tokens across multiple blockchains.

Key Features

  • Client-side embeddable payment widget and SDK for web apps, installable via npm or CDN
  • Multi-blockchain support (EVM-compatible chains and Solana) and broad wallet compatibility
  • Managed integrations (integration ID) and unmanaged configurations for direct accept lists
  • Real-time token conversion and swap routing so payers can use many tokens while receivers get specified assets
  • Fee configuration (multiple fees and protocol fee), fixed-currency amounts, and customizable UI styling
  • Options for passing connected wallet instances and custom RPC providers

Use Cases

  • Accept crypto checkout payments on ecommerce sites and dApps
  • Collect donations or fixed-price payments in stablecoins or tokens
  • Integrate wallet-to-wallet payments for subscriptions, paywalls, or on-chain purchases

Limitations and Considerations

  • Widgets are client-side; server-side rendering requires loading only on the client to avoid SSR issues
  • Unmanaged configurations do not provide server-side callbacks; managed integrations rely on hosted configuration
  • Transactions depend on user wallets and blockchain network conditions (gas fees, latency)

DePay is focused on simplifying Web3 payment integration with a lightweight developer experience and configurable widget options, suitable for sites that need fast, wallet-native crypto checkout capabilities.
