In case you wondered how to actually access your BTC zap: Disambiguated steps: 1 Take your nsec string. 2 Decode Bech32 with HRP=“nsec” → get exactly 32 raw bytes. These bytes are your private key. 3 Make 34-byte data: 0x80 + 32-byte privkey + 0x01. 4 Compute double SHA256 of those 34 bytes → get 32-byte hash. 5 Take the first 4 bytes of that hash (bytes 0-3). This is checksum. 6 Append checksum to the 34 bytes → now 38 bytes total. 7 Convert those 38 bytes to Base58 using Bitcoin alphabet (no 0OIl). Result: WIF string starting with K or L.

Then you can use that to add to your wallet and do whatever.
