Quick Usage

bytom wallet

#!/usr/bin/env python3

from pybytom.wallet import Wallet
from pybytom.utils import generate_entropy

import json

# 128 strength entropy
ENTROPY = generate_entropy(strength=128)
# Secret passphrase
PASSPHRASE = None  # str("meherett")
# Choose language english, french, italian, spanish, chinese_simplified, chinese_traditional, japanese & korean
LANGUAGE = "chinese_traditional"  # default is english

# Initialize wallet
wallet = Wallet()
# Get Bytom wallet from entropy
wallet.from_entropy(entropy=ENTROPY, passphrase=PASSPHRASE, language=LANGUAGE)

# Derivation from path
# wallet.from_path("m/44/153/47/61/89")
# Or derivation from index
wallet.from_index(44)
wallet.from_index(153)
wallet.from_index(47)
wallet.from_index(61)
wallet.from_index(89)
# Or derivation from indexes
# wallet.from_indexes(["2c000000", "99000000", "2f000000", "3d000000", "59000000"])

# Print all wallet information's
print(json.dumps(wallet.dumps(), indent=4, ensure_ascii=False))
