I wonder if there are some convenient set of tools (or a wallet application itself) to work on a cold storage.
As I can understand (correct me if I'm wrong) to work with a cold storage I only need to have abilities to:
- generate a private key of a new wallet
- get the public key and the address of the wallet from the private key
- sign transactions generated by other apps (watch-only wallets) with the private key
Is there are some apps that support all the basic tools that one need on a cold storage computer to work with an Ethereum wallet?
OS: Linux or Windows.
