SovSats
AvailableSovSats is an npm-distributable Bitcoin/sats checkout layer: create invoice, poll status, distinguish processing from settled, and show confirmation UI. It sits on the merchant’s BTCPay instance — it is not a processor.
A developer integrates a mobile-first checkout component and webhook helpers instead of restyling BTCPay’s default customer page.
Build vs buy
Skip writing poll loops, invoice UI states, Next/Express adapters, and HMAC webhook handling for Greenfield invoices.
Differentiation
Settlement-stage machine in the UX (`onProcessing` vs `onSettled`) and framework-agnostic core with an optional React component.
Best fit
Developers, ecommerce operators, and agencies adding sats/Bitcoin checkout to stacks that already include BTCPay.

Why it matters
BTCPay is the settlement engine. SovSats is the customer-facing wait that does not lie about confirmation.
What it does
Creates an invoice, polls until the right stage, renders waiting/confirmed states, and exposes webhooks so fulfillment happens on settle.
Operational advantage
The expensive mistake is fulfilling on mempool noise. SovSats encodes the two-phase settlement model in the UX and callbacks.
Build vs buy
Skip writing poll loops, invoice UI states, Next/Express adapters, and HMAC webhook handling for Greenfield invoices.
Interface advantage
Waiting/polling and order-confirmed screens that look like commerce, plus npm/package collateral for a clean developer story.
What makes this different
Settlement-stage machine in the UX (`onProcessing` vs `onSettled`) and framework-agnostic core with an optional React component.
