about electrum, i am newbie, i have two questions.
First, i have a webshop, i want to generate 10k addresses and use on my webshop, after the addresses were generated, how to export them?
**generate by command wallet.storage.put( 'gap_limit', 10000 )
Go to wallet>Private Keys>Export and choose either json or CSV format. You can then view the private keys in which ever format you chose. Both can be opened with a text editor.
Second, what is the max 'gap_limit' , after i input "wallet.storage.put( 'gap_limit', 75000 )", i close and reopen electrum, but it doesn't work.
There's no max gap_limit AFAIK. Use wallet.storage.write() and reopen your Electrum. Just be aware that having these many addresses can cause your Electrum to run slowly.
