Payment Kernel
AvailablePayment Kernel is self-hostable payment infrastructure: a router, adapters (BTCPay, Lightning, P2P/email confirmation), unified payment objects, settlement proofs, and a one-command installer. The merchant owns the stack.
A developer-led buyer can stand up multi-rail accept/settle on their own machines — rails they can replace — rather than renting a gateway that can disappear.
Build vs buy
Start with a functioning kernel (API, router, adapters, CLI installer, Compose) instead of designing payment orchestration from zero.
Differentiation
Self-hosted kernel with replaceable adapters and cryptographic settlement proofs — not a hosted gateway and not a card processor.
Best fit
Developer-led payment infrastructure buyers, high-risk operators building owned rails, and SaaS platforms adding alternative accept.

Why it matters
If your payment vendor can turn you off, you do not own checkout. The kernel is the opposite bet: host the orchestration, swap the adapters.
What it does
Applications create a payment; the kernel routes across configured rails, waits for settlement, and emits proofs and webhooks.
Operational advantage
The scarce asset is orchestration: first-to-settle, proofs, webhooks, and adapters that do not all die when one vendor revokes access.
Build vs buy
Start with a functioning kernel (API, router, adapters, CLI installer, Compose) instead of designing payment orchestration from zero.
Interface advantage
Developer-facing docs and an installer flow (`create-sovereign-kernel`) plus operator/marketing surfaces that make self-hosting feel like a product, not a gist.
What makes this different
Self-hosted kernel with replaceable adapters and cryptographic settlement proofs — not a hosted gateway and not a card processor.
Where this gets used
- Applications that need BTC / LN / P2P without a custodial processor
- A platform that wants replaceable Docker adapters
- High-scrutiny merchants who will operate their own settlement path
Commercial paths
- Commercial source license for platforms adding sovereign rails
- Agency install-and-support retainer
- Exclusive acquisition of the kernel IP
Best buyer fit
Developer-led payment infrastructure buyers, high-risk operators building owned rails, and SaaS platforms adding alternative accept.
Current status
Available for commercial source license or exclusive acquisition. Docs and installer are part of the package.
Notes
v1 is single-merchant oriented. The buyer operates BTCPay/LND/IMAP (or equivalent) rails. This is not a card-acquiring product.
Key capabilities
- Multi-rail payment orchestration (first healthy/settling rail)
- Adapters for BTCPay, Lightning, and P2P/email confirmation
- Signed settlement proofs and HMAC webhooks
- Unified payment object for applications
- create-sovereign-kernel installer and Docker Compose
