Docs › Privacy and network
Besides its own Tor, Biscuit can use I2P or any SOCKS5 proxy, or no network at all. Everything is in Settings › Network › Proxy.
With Let Biscuit manage this list ticked on the Node tab, Biscuit connects to a Monero node on I2P from its built-in list. Prices and the Journal aren’t fetched over I2P. Bitcoin and Litecoin go through the same proxy, and public Electrum servers usually can’t be reached that way: use your own server on your local network.
Set Proxy to socks5 and enter its host and port. A Tor you run yourself counts too: choose Tor and untick Automatic. Biscuit treats any proxy like Tor mode: exchange swaps are off.
Settings › Network › Offline › Disable all network connections (offline mode) stops every connection. Biscuit then can’t sync or send, but it can sign: that’s the mode for the offline computer in offline signing.
