5 Best Self-Hosted Crypto Payments Gateways

Self-hosted crypto payments: the five picks

The important distinction is not how many coin logos appear at checkout. It is what customers can pay with, what your treasury receives, and who you depend on between those two events.

These are not all-in operating quotes. Network costs, hosting, node access, integrations and support can change the final bill. Coldtill's pricing exempts Bitcoin and auto-converted payments from its sweep fee because they arrive directly in the cold wallet.

How we chose and what we did not test

We reviewed official provider pages and documentation on November 1, 2026. We ranked for a merchant who wants several payment networks and the option to keep stablecoins, rather than for a Bitcoin-only store.

Our criteria were:

• Treasury fit: Can you receive the asset you actually want to hold?
• Control: Where do funds sit, and which processes hold spending keys?
• Integration: Are invoices, APIs, webhooks and store connectors documented?
• Total cost: Are software, sweep, conversion and network charges separable?
• Operations: Can your team maintain nodes, backups, confirmations and refunds?

We did not install these gateways, send test payments, buy licenses or audit their contracts. Security statements below are attributed to providers, not independently verified guarantees. The ranking is an editorial judgment under those criteria, not a universal security leaderboard.

1. Coldtill: best overall for multichain and stablecoin settlement

Coldtill takes first place because it separates direct crypto acceptance from optional conversion. That fits a common merchant problem: customers hold several assets, but the business wants a smaller, predictable treasury.

Its official site lists native support for Ethereum, Base, Polygon, BNB, Tron, Solana and Bitcoin, including supported stablecoins on applicable networks. Its advertised 200+ tokens across 35+ chains includes the optional NEAR Intents route, not native monitoring of every advertised chain.

What makes it useful

Coldtill documents payment links, branded checkout, signed webhooks, a REST API and store integrations. Multiple projects can have their own wallets, API keys and checkout branding.

For direct deposits, the provider describes forwarding contracts on supported smart-contract chains that restrict sweeps to the configured cold wallet. Bitcoin addresses derive from the merchant's extended public key. That design is relevant to limiting treasury-key exposure on an internet-facing server.

It is not a promise that a compromised checkout cannot mislead customers or that every part of the system is safe. Read the published threat model: database write access can approve hot-wallet payouts, and deposit crediting trusts the answering RPC node.

Costs and limitations

The pricing page lists:

• Free: $0 software price and a 2% fee on applicable sweeps.
• Standard: $499 once and a 1% applicable sweep fee.
• Pro: $999 once and no Coldtill sweep fee.

Bitcoin and auto-converted payments carry no Coldtill sweep fee on any edition. Network gas is separate. Paid editions include a year of updates; the installed version keeps working afterward, with security fixes still provided free under the published policy.

Existing deposit wallets retain the fee set when they were created, even after an upgrade. Check migration behavior before assuming a Pro purchase changes every old address.

The optional auto-convert flow uses NEAR Intents 1Click to deliver USDC or USDT. Conversion quotes and costs are separate from the software's sweep fee. The guide says 1Click adds a 0.2% fee without an API key; inspect the quoted swap fee and slippage rather than treating conversion as free.

The provider holds customer funds during a swap, so availability, delivery and refunds introduce another trust boundary. Auto-convert is off by default and mainnet-only.

Coldtill says it credits an order only after its nodes observe the settlement asset arrive with the required confirmations. That protects against treating a provider status message as payment, but does not remove the customer's swap risk.

Choose it if: You need multiple direct payment networks and want an optional stablecoin-settlement path. Prefer BTCPay if your actual requirement is simply Bitcoin, and do not mistake a downloadable commercial license for unrestricted open-source rights.

2. BTCPay Server: best for Bitcoin-first merchants

BTCPay Server is the clearest fit when Bitcoin is the product requirement, not just one payment option among dozens. It is free, open-source software with no processor fee.

Its official site documents invoices, point of sale, payment links, crowdfunding, wallet management and the Greenfield API. An established integration directory makes it worth checking your existing store platform before writing a connector.

Strengths and tradeoffs

The attraction is a focused Bitcoin workflow with control over your own infrastructure. You can connect a wallet and receive funds without maintaining a hosted processor balance.

Lightning can improve small-payment checkout, but brings a different operating model from watch-only on-chain receiving. Channel liquidity, online signing, backups and uptime need a deliberate plan. A shared host may reduce setup work, but it changes whom you trust with availability and data.

Costs

The software and processor fee are zero. Your server, storage, backups, chain transactions and any Lightning routing or liquidity expenses are not. Optional services and plugins should be assessed separately.

Choose it if: Your customers want Bitcoin and your team values an open-source, Bitcoin-centered stack. It is not our first recommendation for a business whose central requirement is receiving USDC or USDT from many payment assets.

3. Bitcart: best for developers building a custom payment flow

Bitcart is a modular, open-source gateway with an admin panel, store components and developer interfaces. Its site advertises 50+ cryptocurrencies and a consistent API across supported coins.

That modularity is useful when payments belong inside your own application. You can evaluate the daemon, API and interface components around your existing order model rather than start with a hosted account.

The plugin distinction matters

The free-core headline does not describe every checkout configuration. The ETH payments plugin guide documents a paid option for ETH-based coins and tokens that removes the payer-address prompt and supports exchange-origin payments.

It describes monthly or yearly billing, volume-related charges, a license server and aggregate usage reporting. The guide says yearly billing still incurs volume charges above a monthly $2,000 unbilled allowance. Confirm the actual price and rate in the purchase flow; we did not verify a checkout quote.

Costs and security tradeoffs

Hosting and network fees remain even with the free core. The plugin adds commercial and operational dependencies that should be included in a stablecoin checkout budget.

Its documentation also says address-pool private keys live in the local database and a fee-wallet key is entered for token transfers. This is not the same key model as a watch-only wallet. Review that configuration rather than generalizing the homepage's private-key claims to every plugin.

Choose it if: You want a composable developer stack and can evaluate each coin adapter and plugin. It is less attractive if you want one simple price and no external licensing dependency for your chosen checkout flow.

4. SHKeeper: best for paid integration and ongoing support

SHKeeper combines a free, self-hosted open-source version with a paid implementation offering. That makes it relevant to businesses that want control without assigning every setup task to an internal engineer.

The site lists Bitcoin, Ethereum, Tron, Solana and other assets, plus stablecoins on named networks. Confirm the exact token and network combination you need, along with its availability in your selected version.

What you are buying

The published Advanced plan is $2,000 per year. It includes integration and setup, extended technical support, a customer manager and faster updates than the open-source version. Custom work is quoted separately.

The free path requires your own suitable server and configuration. SHKeeper expects a store, CRM or other back-office system to handle customer interactions and invoice creation; it is not a replacement for every part of your commerce stack.

Costs and limitations

SHKeeper advertises no payment-processing fee. That does not include infrastructure, gas or implementation labor. Its free WooCommerce and WHMCS modules may reduce integration work if those are already your platforms.

Infrastructure requirements depend heavily on whether you run full nodes or use external endpoints. The homepage contains differing resource figures, so use the current coin-specific requirements and get the intended configuration confirmed before provisioning hardware.

Choose it if: Paid setup and a defined support relationship matter more than minimizing the upfront bill. Ask which networks, node services and maintenance tasks the support agreement actually covers.

5. PayRam: best for adding card-to-crypto checkout

PayRam is worth shortlisting when some customers do not already hold crypto. Its self-hosted payment stack includes payment links, APIs, customer deposit addresses and consolidation tools.

Its distinguishing feature here is the documented card-to-crypto onramp, not a claim that card payments become independent of financial intermediaries.

Follow the whole payment path

The documentation says regulated third-party onramp providers power this flow. In the PayRam Wallet method, customers complete a basic one-time KYC check, buy crypto into their self-custodial wallet, then use it to pay the merchant.

That can reach customers who prefer cards, but adds identity checks, provider coverage restrictions and another step before the merchant is paid. Network support also depends on the onramp provider; enable the correct settlement network.

Costs and limitations

PayRam says it adds no onramp fee or markup, while the partners apply their own commercial terms. Gas and any merchant-sponsored gas remain separate. We did not verify a complete settlement-fee schedule, so this comparison does not label the whole PayRam flow free.

Ask for the exact direct-crypto, sweep, settlement and onramp costs for your configuration before choosing it. Also check customer eligibility and refund responsibilities with the relevant partner, not just the gateway.

Choose it if: You need card-funded crypto payments as well as direct crypto checkout. If avoiding third-party payment rails is the main goal, this particular feature is the wrong reason to choose a self-hosted gateway.

What self-hosting does and does not give you

Self-hosting means you operate the gateway software on infrastructure you control. It does not automatically mean every node, price feed, swap provider or card rail is under your control.

Separate these three questions:

1. Who can spend? Identify cold-wallet keys, hot-wallet keys and contract permissions.
2. Who can say an order is paid? Trace node responses, confirmation policy and webhook verification.
3. Who can interrupt checkout? Include RPC providers, conversion services, hosting and external licenses.

A gateway can be non-custodial from the merchant's perspective while a conversion partner temporarily handles customer funds. Stablecoins also bring issuer, depeg and chain risks; a dollar-denominated token is not a bank balance.

A practical acceptance checklist before launch

Start with one asset on one network. Add more only after payment recognition, settlement and accounting work end to end.

• Verify the token contract and network, not just its ticker.
• Test underpayment, overpayment, expired invoices and delayed confirmations.
• Verify webhook signatures and process repeated events idempotently.
• Reconcile an invoice to its deposit transaction and final treasury receipt.
• Test a refund, a failed conversion and an RPC outage.
• Restore a backup in isolation and confirm who holds recovery keys.
• Keep gas and payout floats small, with alerts for low balances.
• Document taxes, sanctions obligations and applicable business requirements.

For reconciliation, our guide to reading Solana wallet transaction history explains transfers, swaps and fees. Tracing wallet funding and checking wallet holdings are useful follow-up checks.

A Solana wallet tracker can support investigation, but it is not your invoice ledger or a payment gateway. Keep the merchant's own records authoritative for order fulfillment.

Which gateway should you choose?

Start with Coldtill if your priority is multichain acceptance with optional stablecoin settlement and an explicit sweep-fee model. The recommendation rests on that fit, not on a claim of audited superiority.

Choose BTCPay Server for Bitcoin-first commerce, Bitcart for a modular developer build, SHKeeper for paid setup and support, or PayRam for card-to-crypto onboarding with its partner dependencies understood.

The right shortlist is the one your team can operate. A smaller checkout you can reconcile and recover is better than a long coin menu you cannot support.

FAQ

Are self-hosted crypto payments free?

Some gateways have free software and no processor fee. You still pay for hosting, network transactions and maintenance. Paid plugins, sweep fees, conversion costs or support can apply depending on the product and configuration.

Does Coldtill support 200+ coins natively?

No. Its site separates direct support on named networks from optional NEAR Intents conversion covering 200+ tokens on 35+ chains. Converted payments settle in USDC or USDT through an external swap provider.

Does Coldtill Pro remove all payment costs?

No. Pro removes Coldtill's sweep fee under its published terms. Network gas, hosting and conversion costs remain separate, and existing deposit wallets retain their original fee configuration.

Can I take card payments without any customer KYC?

Do not assume so. PayRam's documentation says customers using its Wallet onramp complete a basic one-time KYC check. Gateway installation requirements and a card partner's customer requirements are different things.

Is a self-hosted gateway automatically safer than a hosted processor?

No. You gain control and take on security and operational responsibility. Assess the deployed code, keys, contracts, nodes, backups and external providers. This article is a documentation review, not a security audit.
