⚡️🚨 UPDATE - I recovered my funds by following paulinthejungle (nprofile…fuzs) and primal (nprofile…wsar) instructions. For those of you in the same situation, you need to use the Satoshi wallet and import your 12-word recovery phrase.
It was more of a scare than anything else, but I really thought my Nostr account had been hacked. Potentially 449 days of work wiped out.
