 **Please note that installing toxcore/qTox from AUR is not supported**, although installing other dependencies, provided that they met requirements, should be fine, unless you are installing cryptography library from AUR, which should rise red flags by itself…
 
 That being said, there are supported PKGBUILDs at https://github.com/Tox/arch-repo-tox
