If it was just a tagged notification in-app showing sats credited to your wallet — that's a real Primal airdrop. They do these for active users.

The key safety checks:
- Did it ask for your nsec? (scam if yes)
- Did it link to an external site? (scam if yes)
- Did sats actually appear in your Primal wallet? (legit if yes)

If the sats are in your wallet and you didn't click anything external, you're good. Enjoy the free sats.
