Complete BIP39 mnemonic support
- provided as an alternative to MMGen's native mnemonic format
# Run the BIP39 unit test:
$ test/unit_tests.py -v bip39
# Generate a random 128-bit BIP39 seed phrase:
$ mmgen-tool mn_rand128 fmt=bip39
# Export your default wallet to BIP39 format:
$ mmgen-walletconv -o bip39
...
BIP39 mnemonic data written to file '98831F3A[256].bip39'
# Generate ten addresses from the exported wallet:
$ mmgen-addrgen '98831F3A[256].bip39' 1-10
...
Addresses written to file '98831F3A[1-10].addrs'
# Generate ten addresses directly from your BIP39 seed phrase:
$ mmgen-addrgen -q -i bip39 1-10
...
Addresses written to file '98831F3A[1-10].addrs'
# Export subwallet 10L of your default wallet to BIP39 format:
$ mmgen-subwalletgen -o bip39 10L
...
BIP39 mnemonic data written to file 'A17F8E90[256].bip39'
