Часта задаваныя пытанні
-
Does this store my private keys?
-
No. This plugin uses KPUB (Extended Public Key) only. Private keys and mnemonics are never stored or required.
-
Can I spend from addresses generated by this plugin?
-
Yes, but not through WordPress. This plugin is watch-only. To spend funds, use your wallet software (Kaspium) where you control the private keys.
-
How does payment detection work?
-
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.
-
What happens if the exchange rate changes?
-
Payment amounts update in real-time based on current exchange rates. Customers see the latest KAS amount on the checkout page.
-
Will addresses appear in my Kaspium wallet?
-
Yes. Addresses are generated sequentially starting from index 0, so they automatically appear in Kaspium wallets.
