Why this conversation
Network-exposure English: the one question to ask before opening anything, and how to offer the safer path without a security lecture.
Dialogue
Priya: Can we open 8545 on the router so I can hit your Anvil from my phone?
Jay: Before we open anything: who can reach that port afterwards?
Priya: Anyone on the internet, I suppose. It's just a test chain.
Jay: A test chain with anvil_setBalance and no auth. Someone finds it, mints themselves a million test ETH, and we spend a morning confused. Not a disaster, just a waste.
Priya: So what instead?
Jay: Tailscale. Your phone joins the tailnet, Anvil listens on all interfaces, and the RPC is http://100.111.162.0:8545 for you and nobody else. I need to restart Anvil with --host 0.0.0.0 for that.
Priya: Does restarting lose the state?
Jay: No, it's on a state file. Only the listener changes. I'll do it after the current test finishes, not during.
