<h4>Frequently Asked Questions</h4>
<h4>Does this store my private keys?</h4>
<p>No. This plugin uses KPUB (Extended Public Key) only. Private keys and mnemonics are never stored or required.</p>
<h4>Can I spend from addresses generated by this plugin?</h4>
<p>Yes, but not through WordPress. This plugin is watch-only. To spend funds, use your wallet software (Kaspium) where you control the private keys.</p>
<h4>How does payment detection work?</h4>
<p>The plugin polls the Kaspa API to check if funds have been received at the order payment address. When the required amount is detected, the order is automatically completed.</p>
<h4>What happens if the exchange rate changes?</h4>
<p>Payment amounts update in real-time based on current exchange rates. Customers see the latest KAS amount on the checkout page.</p>
<h4>Will addresses appear in my Kaspium wallet?</h4>
<p>Yes. Addresses are generated sequentially starting from index 0, so they automatically appear in Kaspium wallets which scan low indices.</p>
