Generate a BIP39 Seed Phrase with Dice

1. Gather Materials

• Dice (D20 + D10 or multiple D6 + coin)
• BIP39 Word List (2048 words, official GitHub repo)
• Paper & Pencil (destroy when done)
• Offline Computer (air-gapped or live USB)

2. Pick Your Dice Method

• Method A: Roll 2×D20 + 2×D10 → map to word index
• Method B: Roll D6 + coin flips → use lookup table

3. Roll & Record

Each roll combination yields a number 0–2047. Note it down in sequence until you have 23 entries.

4. Lookup Words

Use your 23 numbers to pull words from the BIP39 list. Write them down in order.

5. Compute Checksum Word

On your offline computer, run a BIP39 tool/script to derive the 24th (checksum) word from your first 23.

6. Verify Seed Phrase

Import all 24 words into an offline‐capable wallet to confirm correct address derivation.

Security Considerations

• Use fair dice & randomized rolls
• Stay offline (air-gap) throughout key generation
• Store backups in metal/paper safes
• Never share your phrase
