DiceVault Core

Offline dice → BIP39 recovery phrase tool.

What this is

• Physical dice (or secure system random) entropy
• Unbiased rejection sampling
• Offline checks before entropy and before phrase creation
• Backup verification, then session destroy
• No seed storage, no vaults, no multisig, no audit platform

What this is not

• Not a hardware wallet
• Not a vault manager
• Not a multisig coordinator

Run

python -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install -r requirements.txt
python -m pytest tests -q
python main.py

Flow

1. Security notice
2. Phrase length (12 / 24)
3. Entropy source
4. Dice profile
5. Offline verification
6. Enter / accept dice groups
7. Silent offline recheck → create phrase
8. Word review → full review → confirm
9. Destroy session

Honest limit

This is desktop software. Windows swap, malware, and screen capture are outside its control. Dedicated offline hardware remains stronger for high-value keys.
