​
Overview

Autopilot uses a single BIP-39 seed phrase to derive both:
  • a Nostr identity (NIP-06 keypair)
  • a Spark wallet identity (Spark keyset)
This keeps identity and wallet recovery unified: one seed phrase restores both. Note: The seed phrase and nsec are secrets. Treat them like a password.

​
The Keys You See in Autopilot

  • Nostr public key (npub...): your public Nostr identity. Safe to share.
  • Nostr secret key (nsec...): private signing key for Nostr events. Never share.
  • Spark public key (hex): public identity for your Spark wallet. Safe to share.
  • Seed phrase (12 words): root secret that regenerates all of the above. Never share.

​
How They Relate

  • The seed phrase is the root.
  • The Nostr keypair is derived via NIP-06 from the seed phrase.
  • The Spark wallet keys are derived from the same seed phrase using Spark’s keyset derivation path.
  • The nsec is only one derived key; if you have the seed phrase, you can re-derive the same nsec.

​
Recovery Requirements

To recover both Nostr and Spark identities later, keep:
  • the seed phrase (12 words)
  • the passphrase, if one was used (optional)
  • the network (mainnet/testnet/regtest)
  • the Spark keyset + account number (derivation path)
If any of those change, you may derive different wallet keys.

​
Default Behavior in Autopilot

  • Generates a 12-word BIP-39 seed phrase.
  • Uses that seed to derive:
    • NIP-06 Nostr keys
    • Spark keys with the default keyset

​
CLI Equivalents

You can reproduce the same flows with the CLI: 
# Nostr: new seed + keypair
oa nostr new --words 12

# Spark: derive wallet keys from a mnemonic
oa spark derive --mnemonic "word1 ... word12" --json

​
Security Tips

  • Do not paste nsec or the seed phrase into chat or logs.
  • Prefer a secure offline backup of the seed phrase.
  • Treat any screenshot showing the seed phrase as sensitive.
