There is a known bug with Ledger (through Metamask) that will currently not let our users sign management transactions. We are aware of the issue and working on a solution. For the time being please use a different method to claim the domains. It will be possible to transfer the domains to Ledger later.
What does claiming mean?
Claiming is the process of pushing your domains from our database on to the blockchain, and into your cryptocurrency wallet. Once a domain is claimed, the user has full custody over their domain. If you wish to use, sell or gift a domain - you must first claim it .
