Build vs buy

Why not just build it yourself?

Because payment code is where small mistakes cost real money — and getting it right takes months you could spend selling.

Build it yourself

  • Three to six months of engineering before the first live payment.
  • You own every money-handling bug — a rounding error or a missed chain reorg can mark an unpaid invoice paid, or lose funds.
  • Ongoing maintenance as chains, tokens and RPC providers change.
  • No test suite, no audit trail, no one to call.

Buy Kovarra

  • Live in 30 minutes with a one-command installer.
  • The money logic is already correct — 82 automated checks cover every payment path.
  • Underpayments, overpayments, expiries and chain reorgs are handled and tested out of the box.
  • Full source code you can read, extend, and keep — plus 12 months of updates.

Security

Non-custodial by architecture — not by promise

The difference that matters: your money is never in a place anyone else can touch.

The server never holds a private key or a seed phrase, and contains no code that can sign a transaction. It derives receiving addresses from the public keys you provide, so funds land straight in your own wallet. This isn't a policy you have to trust — it's enforced in the code. An automated non-custody check scans the entire codebase on every build and fails it if any key material or signing capability ever appears:

✓ non-custody check passed: no key material or signing code in source.

You receive the full source, so your own developer or any auditor can confirm it in minutes. The admin dashboard even derives and shows your first receiving addresses so you can match them against your own wallet before going live.  Read the wallet-setup guide →

FAQ

Questions merchants ask

How is it non-custodial? Prove it.

The server is built so it physically cannot spend: it stores only your public keys or plain receiving addresses — never a private key, never a seed phrase — and contains no transaction-signing code at all. An automated check in the codebase fails the build if any is ever introduced. You receive the full source, so your own developer (or any auditor) can confirm this in minutes. The dashboard even shows you the derived addresses so you can match them against your own wallet.

What exactly do I receive?

The complete source code (server, checkout, dashboard, blockchain watchers, WooCommerce plugin), a one-command installer, full documentation (install, API, wallet setup), and a signed license key issued to you. Managed deployment additionally includes us installing it on your VPS and domain and walking you through your first live payment.

How fast is delivery?

Within 7 days of your payment confirming on-chain — usually much faster. You'll receive the repository, your license key, and setup instructions at the email you enter at checkout.

What about updates?

12 months of updates are included (new chains and features as they ship, fixes, security patches). Your license — and the software — never expires; after 12 months you can renew updates or simply keep running the version you have. It's yours.

What is the refund policy?

If we fail to deliver within 7 days, you get a full refund. Because the product is delivered as complete source code, all sales are otherwise final once delivered — that's exactly why the live demo exists: test everything before you buy.

Who is behind this?

The team is private, deliberately — for the same reason our customers value this product. You are not asked to trust us: you receive the full source code, the software runs on your own server, settles to your own wallet, and every claim on this page can be verified in the code itself.
