Using a VPN isn't really going to help you that much in terms of security though. VPNs are mostly for privacy purposes; though I'm not sure with SurfShark. I'd personally recommend Mullvad.
one thing to keep in mind: any one of them could be a honeypot. that's the danger of centralized, opaque services.
i used to swear by PIA because their no-logging policy was tested twice in court, but then they got bought by kape technologies, who is known for collecting and selling user data.

another option is to route your traffic over tor. wasabi wallet does this by default.
