Auth & Signers

Any time Amethyst produces a signed Nostr event, it goes through a NostrSigner. There are three kinds; all three implement the same abstract contract so feature code doesn't care which one the user has configured.

When to Use This Skill

• Adding a new flow that publishes an event (follow, post, react, zap, profile edit).
• Reviewing whether a feature works when the user has a remote bunker signer or an external Android signer.
• Debugging "Sign request approved but nothing happens" / timeouts on sign operations.
• Onboarding a new signer kind (hardware signer, browser extension, etc.).
• Understanding the NIP-46 bunker request/response taxonomy.
