libcurl

libcurl ships as a system framework within macOS itself, not as a standalone downloadable component. The version you have is determined entirely by which version of macOS your Mac is running. Since a native Apple Silicon build has been confirmed in the wild, Apple has already shipped native libcurl as part of recent macOS releases. If you are developing against libcurl, or if a third-party application uses the system libcurl and was previously running under Rosetta, the path forward is straightforward: update your Mac to the latest macOS your hardware supports via System Settings → General → Software Update. This will bring you to a native Apple Silicon version of libcurl automatically as part of the macOS update. If you are a developer who compiles or links against libcurl directly and need to ensure you are using the native build, verify that your Xcode toolchain is current (Xcode → Check for Updates) and that your project's build settings target Apple Silicon (Architecture: arm64 or Universal Binary). For applications that embed their own copy of libcurl rather than using the system version, check with the app vendor for a native build — the same principle applies: updating the host application will bring the embedded native libcurl.
