[1] is the console Consol make_seed(xxx) the same fuction and security as going through the GUI when makeing a new wallet to generate a seed?
Yes.
Reference:
github.com/spesmilo/electrum/blob/master/electrum/wallet.py#L3978-L3986[2] does make_seed(256) for a 24 words seed, is that as robust and safe as the defualt GUI 12 word at the begining gui for a new wallet
Of course, higher entropy means better security. But that doesn't mean that 12 words isn't safe.
However, given how Electrum generate its mnemonic, the correct entropy for 12 word mnemonic is 132 bits.
So a 24-word mnemonic should be
make_seed(264)Reference:
github.com/spesmilo/electrum/blob/master/electrum/mnemonic.py#L205-L206[3] could you use a make_seed(512) for a 48 word seed if you wanted? what are the risks
Yes, but longer mnemonics are more prone to human error.
