Can we store our .sol domain on a hardware wallet instead of keeping it on a hot wallet like Solfare?
you can transfer it to any Solana address.
@solanageek Is right you can transfer it to any Solana address, so you should be able to send it to any hardware wallet that supports Solana
I can confirm it is possible to store and transfer domains with a ledger nano for 2FA.
But, the ledger UX is so bad, in many or most cases you cannot read transactions sufficiently to know what you are signing. This problem has nothing to do with Bonfida though, I guess we just have to wait for ledger to properly implement Solana.
