Bitcoin Wallet Generation Script
|
|
|
|
This script generates a Bitcoin wallet and stores it in a KeePassXC database file (KDBX format).
|
|
The wallet includes a BIP-0039 mnemonic seed phrase, Bitcoin address, and a QR code representation
|
|
of the seed phrase. The database file is password protected to ensure the security of the wallet.
|
|
|
|
Usage: ./generate_btc_wallet.py
