How is a domain name recognized and resolved?

A KNS domain name is recognized and resolved to an address through an inscription, with Each name has a unique inscription associated with it.

Once a name inscription is created or transferred, it must go through a confirmation process before it can be fully resolved to the designated address.

Why does it show “insufficient funds”?

To ensure a smooth inscription process, KNS reserves additional KAS as a transaction fee. Once the transaction is completed, any unused amount will be refunded to the original address.

If your wallet balance is exactly equal to the inscription fee, the extra transaction fee may cause an insufficient funds error. Please ensure your wallet has enough KAS to cover the required amount.

Required Wallet Balance:

Domain Inscription: Requires a 5% transaction fee Wallet Balance Required = Amount × 1.05

Text Inscription: Requires a 100% transaction fee Wallet Balance Required = Amount × 2

What if I paid for a domain but it was not verified?

If you paid for a domain but it was not verified, it is likely because two users attempted to register the same domain at the same time, and only one was able to successfully obtain the verified domain. However, both users may have initially paid the registration fee.

This situation arises due to the current limitations of Inscription technology, which processes domain registrations based on the order of blockchain confirmations. If two identical inscription transactions are included in the same block, only one will be verified, while the other may result in a payment without receiving the verified domain.

How to Refund?

1. Verification Process

• Only the first confirmed inscription will be verified.

• If two identical domain inscriptions occur at the same time, only the earliest confirmed one will be verified.

1. Refund Policy

• If you paid for the inscription but it was not verified, you will receive a full refund.

• Simply fill out the Refund Application Form, and the fees will be refunded to your original payment address.

• Refund requests must be submitted within one month after the inscription attempt. KNS will process the refund promptly.

1. Future Improvements

• This issue is due to the current inscription-based system.

• Once KNS migrates to smart contracts, domain registrations will become more efficient, and such conflicts will no longer occur.
