Syscoin aliases replace long complicated coin address with an easy-to-remember string of characters. These aliases can be used across all of Syscoin’s services and make it much easier to send and receive Syscoin.

 
Aliases are lower-case just like email addresses so make sure to double check your entries!
Syscoin aliases are also unique like domain names, and only one user can own a unique alias at a time. If you do not renew your alias by updating it then after a year it will be returned to the network for others to purchase.
