Please add sing-box to CachyOS repos. Yes, it’s available in AUR, but many packages have been compromised. It’d be great to have a popular VLESS and Hysteria 2 client in CachyOS repo
AUR is fine. You just have to know what you are doing. You could clone it and build it yourself too.
AUR is fine, but it’d be better having this client in official Cachyos repo
