Use the Sign Message feature from your Scash wallet to verify ownership of a wallet address that belongs to you.
Enter the following data into the wallet software:
Address: scash1qh6m392ja4qwa302h5m469rs8nrahqtzd5h4zx8
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.
