longbridge-pro
The PKGBUILD downloads a prebuilt x86_64 binary (.deb) from assets.lbctrl.com, which is a CDN/asset host associated with Longbridge (lbctrl.com appears to be Longbridge's infrastructure domain, and lbkrs.com is also a Longbridge-related domain). This is a proprietary trading platform distributed as a prebuilt binary — not compiled from source — which is a common pattern for commercial desktop apps in the AUR. The sha256sums are present and pin the download. The host (assets.lbctrl.com) is not GitHub releases or a well-known official mirror, but it appears to be the vendor's own CDN infrastructure rather than a random personal host. The main concern is that this is an executed prebuilt binary from a host that cannot be independently verified as the canonical upstream, and if the CDN were compromised or the URL repointed, the checksum would be the only protection. This is a standard medium-risk pattern for proprietary binary repacks in the AUR: not clearly malicious, but not source-built either. No obfuscation, no exfiltration indicators, no piracy concerns (it's the vendor's own software with their EULA bundled).
