some of the info i have written down:
electrum wallet info.
Electrum is initially a Bitcoin wallet.
Later some altcoin projects have their Electrum wallets too but I don't know in your post, what is the Electrum wallet?
Is it a Bitcoin wallet or a XRB/ NANO Electrum wallet?
At
https://hub.nano.org/wallets, there is no Electrum wallet for NANO.
