Keysat is the licensing server you run on your own Start9. Buyers pay in Bitcoin via your own BTCPay. Your software verifies signed keys offline. You own the signing key, the customer list, and the payment rails — no SaaS, no middleman, no platform risk.

<h3>Bitcoin payments, your store</h3>
|
|
<p>BTCPay Server on your own Start9 takes the payment. Lightning settles in seconds. Funds go straight to your wallet — no intermediary holds them.</p>
|
|
</div>
|
|
<div class="item">
|
|
<span class="icon">🔐</span>
|
|
<h3>You own the signing key</h3>
|
|
<p>The Ed25519 keypair lives on your hardware. Every license you issue is signed by it. There's no third party who could mint or revoke licenses.</p>
|
|
</div>
|
|
<div class="item">

<h3>Offline verification</h3>
|
|
<p>Your software verifies licenses against an embedded public key. No network call. Your customers' apps work even if your Keysat goes offline.</p>
|
|
</div>
|
|
<div class="item">
|
|
<span class="icon">🎫</span>

<h3>Trials, expiries, seats, entitlements</h3>

<p>Per-product policies for time-limited licenses, multi-seat caps, trial flags, feature entitlements baked into the key.</p>

<div class="item">
|
|
<span class="icon">🏷️</span>
|

<h3>Discount & referral codes</h3>

<p>Percent-off, fixed-sats-off, or free-license codes (no payment). Run launch promos, comp keys for press, track partner campaigns.</p>

<h2>How it works</h2>
|
|
<p class="subtitle">Five steps, end to end.</p>
|
|
<ol class="flow">
|
|
<li>
|
|
<h3>Install Keysat on your Start9</h3>
|
|
<p>Sideload the <code class="inline">.s9pk</code>, or install from <a href="https://registry.keysat.xyz">registry.keysat.xyz</a>. Keysat declares BTCPay Server as a dependency, so you'll have BTCPay running too.</p>
|
|
</li>
|
|
<li>
|
|
<h3>Connect BTCPay in one click</h3>
|
|
<p>Click "Connect BTCPay" in the StartOS Actions tab. You authorize once on your BTCPay's consent page; Keysat auto-detects your store and registers a webhook. No API keys to copy.</p>
|
|
</li>
|
|
<li>
|
|
<h3>Define your products + policies</h3>
|
|
<p>In the Keysat web UI: declare your product, set its price in sats, define a policy (duration, seat cap, trial flag, entitlements). The policy slugged <code class="inline">default</code> drives your public purchase flow.</p>
|
|
</li>
|
|
<li>
|
|
<h3>Embed your public key in your software</h3>
|
|
<p>Copy your Keysat public key into your app's source. Add the SDK (<code class="inline">pip install</code>, <code class="inline">cargo add</code>, <code class="inline">npm install</code>). Five lines of integration code verifies a license at startup.</p>
|
|
</li>
|
|
<li>
|
|
<h3>Share your purchase URL</h3>
|
|
<p>Your buyers hit your public Keysat URL, pay in Bitcoin, get a signed license key delivered. Their copy of your software boots up licensed. You see the sale in your audit log.</p>
|

<h3>Other languages</h3>

<p>Any language with Ed25519 + base32 (Go, Java, Swift, C#, C++, …) can verify Keysat keys. The wire format is fully documented; thin SDKs can be ported in a few hours. Go and Java/Swift SDKs are on the roadmap.</p>
