Someone made a compilation of academic reviews and blogposts here: https://community.signalusers.org/t/wiki-overview-of-third-party-security-audits/13243 but none of them seem to be real security audit reports, ex. compare with real security audits to Delta Chat: https://delta.chat/en/help#security-audits
As I seen in other comment I think that the protocol is audited not really the app and servers In comparison SimpleX is audited pretty regularly
could you provide some source/link to the SimpleX security audits? I would like to look into it, thanks in advance!
