Use the Sign Message feature from your Altecoin wallet to verify ownership of a wallet address that belongs to you.
Enter the following data into the wallet software:
Address: an8R56CCxbabufJM8wE5KuSohmmh8TET1x
Message: <display name from the form below>
Click the Sign Message button in the wallet, and copy/paste the resulting Signature at the bottom of this form.
Finally, click the Claim button below to claim your address, which will display your custom display name instead of the default wallet address on this site.
NOTE: You can update your claimed address at any time, as often as you wish. To remove a previously claimed display name, simply sign a blank message to return the address back to its original value.
