The Blockchain network processes Bitcoin (BTC) payments, which may charge a networking fee. This also applies to Wallet providers, as they also could charge their own fee. 

Please ensure that you include these fees in the price of the challenge.

If we receive a payment that is below the required amount, we will contact you on the email registered on file to settle the remaining amount. 

Kindly check the Spam and Junk folders in your email account for our email if you have not received your Evaluation Stage Credentials.

Your credentials will be sent to you once the full amount required has been paid.
