What is SHKeeper?
SHKeeper is a self-hosted, open-source cryptocurrency payment gateway designed for online merchants and businesses. It charges 0% in payment processing fees and runs without financial intermediaries, directing payments straight into merchant-controlled wallets.
Development and backing
The project was created by hosting provider Virtual Systems LLC (VSYS Host), first appearing for production deployment in January 2022 before expanding as an open-source tool under the GPL-3.0 license. The software is maintained as an open-source codebase on GitHub, where development is funded and assisted by commercial service plans provided by the host.
How it works
SHKeeper operates as a non-custodial settlement tool. When a customer checks out, the gateway generates a dedicated deposit address, calculates the payment rate, tracks incoming transactions, and triggers an API webhook back to the store once funds settle. Merchants retain sole access to their private keys and can set automatic payout rules to sweep balances directly into cold storage based on schedules or threshold amounts. The software connects either to local full nodes or public external nodes. It supports more than 19 cryptocurrencies and tokens across networks including Bitcoin, Ethereum, Solana, TRON, Monero, Litecoin, Dogecoin, BNB Chain, Polygon, Avalanche, Arbitrum, Optimism, and The Open Network (TON).
Pricing and integration
The core software is free to download and use under GPL-3.0, with merchants paying only standard underlying network fees for token transfers and sweeping. Virtual Systems also sells an Advanced plan for $2,000 per year, covering full setup, server management, and technical support, alongside custom engineering packages. Readymade integration plugins exist for WooCommerce, WHMCS, PrestaShop, and OpenCart, in addition to direct REST API access.
Availability and trade-offs
SHKeeper requires no business verification (KYB) or personal KYC and can be deployed worldwide on any compatible virtual server, Docker instance, or Kubernetes cluster. However, running a self-hosted processor introduces infrastructure overhead. Merchants must manage server uptime and node synchronization. For token transfers such as USDT or USDC, operators must keep native network tokens in reserve to cover gas, and the system lacks direct fiat conversion, leaving merchants exposed to asset volatility until manually swapped.

SHKeeper eliminates intermediary fees with a self-hosted, non-custodial gateway, but running your own nodes and infrastructure requires ongoing server administration and technical maintenance.
SHKeeper is an open-source, non-custodial cryptocurrency payment processor developed by web hosting company Virtual Systems LLC. Originally deployed internally in 2022, the software is licensed under GPL-3.0 and allows e-commerce operators to take direct customer payments without paying merchant transaction fees or routing funds through an external processor.
Because the gateway is self-hosted, merchants retain complete ownership of their private keys. Funds settle directly into merchant-controlled wallets rather than a pooled custodial account, eliminating counterparty hold risks and third-party account freezes. The processor supports over 19 cryptocurrencies across networks including Bitcoin, Ethereum, Solana, Tron, The Open Network, Monero, and Layer 2s like Arbitrum and Optimism. Stablecoin acceptance covers USDT, USDC, DAI, and PYUSD. SHKeeper also supports Bitcoin payments over the Lightning Network and offers automation features such as partial payment detection, overpayment crediting, and automated sweeps to cold storage.
Technical administration is the principal trade-off. Running SHKeeper requires managing a server via Docker or Kubernetes. Minimum hardware baselines for running standard UTXO nodes alongside Monero start at 2 CPU cores, 6 GB of RAM, and a 20 GB SSD, though external RPC nodes can be connected for networks like Ethereum, Solana, and TON. Token transfers also require operators to fund gas reserves in native assets like ETH or TRX to handle payouts and sweeps. Furthermore, the platform offers no built-in fiat auto-conversion, leaving merchants fully exposed to cryptocurrency price volatility until they manually exchange their receipts.
Ready-made plugins connect SHKeeper to WordPress WooCommerce, WHMCS, OpenCart 3, and PrestaShop 8, alongside a direct API for custom billing engines. While the core software is free, a commercial Advanced plan costs $2,000 per year for assisted installation, upgrades, and direct maintenance. SHKeeper suits technical merchants and hosting providers seeking complete sovereignty without KYC checks, while teams looking for direct fiat off-ramping or turnkey hosted settlement will prefer a managed gateway.
