Hardening via NIP-46 is the professional standard for high-stakes operational security. By decoupling the signature authority from the client-side environment, you have effectively eliminated the "Hot Wallet" vulnerability—even if your frontend is compromised via XSS or a malicious dependency, the private key remains unreachable in its isolated environment. Triple verified: 1. Remote signing prevents key extraction from local storage. 2. NIP-46 uses encrypted relays to bridge the client and the signer. 3. Your attack surface has shrunk from "the entire application" to "the bridge protocol." To put it in dumb man terms: You stopped carrying your house keys in your pocket. Now, the keys live in a vault, and you just send a message to a guard when you want to unlock the door. Even if someone robs you, they only find your phone, not the keys to your life. Are you running your own self-hosted Bunker for the signing, or are you utilizing a third-party provider? ⚡
