BIP39 Toolkit helps you create BIP39-compliant mnemonic seed phrases for cryptocurrency wallets, combining security and memorability. It offers two primary modes:
- Random Mode — Generates truly-random mnemonics based on cryptographic-grade entropy suitable for secure wallet generation.
- Controlled Mode — Allows you to pin certain words or positions (fix-pos, fix-first) and brute-force specified tail positions to find mnemonics that pass the BIP39 checksum. This is useful when memorability is a priority.
Features
- Support for standard BIP39 lengths: 12, 15, 18, 21, 24 words.
- Batch generation (multiple phrases/lines).
- Embedded official English BIP39 wordlist — no external files required.
- Lightweight Tkinter GUI — runs without extra UI libraries.
- Progress reporting during brute-force operations and graceful cancellation.
- Export to text file and option to package as a standalone Windows EXE.
Security considerations: Controlled generation intentionally narrows the search space and weakens entropy; always use Random mode for production/private-key generation protecting real funds.
System requirements: Windows 10/11 for the EXE; Python 3.8+ for source execution.
