Hi, title is a quote from the F-Droid description, however I don't see the same claim in the Readme.

Can you please clarify? Original Delta Chat was not in any way safe against MITM attacks.

hi @xandro0777 the e2ee in Delta Chat (and any app/client that uses Delta Chat core like ArcaneChat) is safe against MITM attacks thanks to the "protected chats" feature, that is, the green checkmark you see in any chat with a contact you performed a QR/link verification which ensures there is no MITM

you can read more about it offline in the FAQ inside the app or at: https://delta.chat/en/help

Some fragments:

Chat titles with green checkmarks green checkmark mean that all messages in the chat will be end-to-end encrypted and can not be read or altered by compromised e-mail servers or Internet providers.

[...] Guaranteed end-to-end encrypted chats protect against MITM attacks [...]
