Security Notes
The project uses standard cryptographic practices (EIP-3009 with viem for signatures) and relies on the Cronos facilitator for secure payment settlement. No hardcoded secrets were found; sensitive information like private keys and API keys are expected via environment variables or CLI options. The proxy mechanism passes user-provided URLs; ensuring these target URLs are trusted is the user's responsibility. File system access (`/proc/1/cgroup`) is used for platform detection, which is a benign system introspection.
