Crypto wallet generator CLI tool

• Generate brand new crypto wallet address (offline)
• Generate wallet address with prefix (string at the start): [-p] (case-insensitive) or [-P] (case-sensitive)
• Generate wallet address with suffix (string at the end): [-s] (case-insensitive) or [-S] (case-sensitive)
• Generate wallet with different formats (for Bitcoin: Legacy, SegWit, Bech32; for BNB: BEP2, BEP20): [-f]
• Generate wallet from your desired mnemonic string: [-m]
• Generate mnemonic string: [-m] or [-m 12] or [-m 15] or [-m 18] or [-m 21] or [-m 24]
• Generate a lot of wallets at once: [-n]
• Save result into a CSV file: [--csv]
• Copy the generated mnemonic to the clipboard: [-C or --copy]

• -b or -c or --chain: Specify the blockchain ticker to generate a wallet for
• -C or --copy: Copy the generated mnemonic to the clipboard
• -D or --csv: Save output into CSV file with custom or default name ("cw-output.csv") - this is a shorthand for -o csv -F filename
• -f or --format: Specify the blockchain wallet format (for BTC: legacy, segwit, bech32)
• -g or --geek: Display some additional "geeky" info
• -l or --list: List all supported blockchains
• -m or --mnemonic [value]: If used without a value or with 12, 18, or 24, it generates a mnemonic string of that length. If a mnemonic string is provided, it generates a wallet from the given mnemonic. For example:
  • $ cw -m: Generates a default 12-word mnemonic string.
  • $ cw -m 12: Generates a 12-word mnemonic string.
  • $ cw -m 15: Generates a 15-word mnemonic string.
  • $ cw -m 18: Generates an 18-word mnemonic string.
  • $ cw -m 21: Generates a 21-word mnemonic string.
  • $ cw -m 24: Generates a 24-word mnemonic string.
  • $ cw -m "your mnemonic phrase here": Generates a wallet from the provided mnemonic string.
• -n or --number: Specify number of wallets to display (works for HD wallets only, like BTC/LTC/DOGE)
• -p or --prefix: Specify desired prefix for the wallet address (case-insensitive)

We're always looking to support more blockchains! If you'd like to add support for a new chain, please follow these steps:

1. Create a Chain JSON File: Create a new .json file in the src/chains directory. The name of the file should be the ticker symbol of the blockchain (e.g., SOL.json for Solana).

2. Define the Chain Properties: Fill the JSON file with the necessary properties of the blockchain. Here's the structure you should follow:

{
    "title": "Readable Title of Blockchain",
    "network": "Network Type (EVM, Bitcoin-like, etc.)",
    "startsWith": "Starting Characters of Wallet Address",
    "prefixTest": "Regex Pattern to Test Valid Characters in Prefix",
    "apps": ["Array", "of", "Supported", "Wallet", "Apps"],
    "flags": ["Array", "of", "Supported", "Features", "like", "m", "n", "p", "s"]
}

3. Add Formats (if applicable): If the blockchain supports multiple wallet formats (like Bitcoin with Legacy, SegWit, Bech32), you can define them under the formats key:

"formats": {
    "formatName": {
    "format": "formatName",
    "startsWith": "Starting Characters of Wallet Address",
    "prefixTest": "Regex Pattern to Test Valid Characters in Prefix",
    "rareSymbols": "Regex Pattern for Rarely Used Symbols",
    "path": "Derivation Path (if applicable)",
    "purpose": "BIP Purpose (if applicable)",
    "apps": ["Array", "of", "Supported", "Wallet", "Apps"],
    "flags": ["Array", "of", "Supported", "Features", "like", "m", "n", "p", "s"]
    }
    // ... other formats
}

4. Submit a Pull Request: Once you've added the new chain file, please submit a pull request to the main repository. Make sure to provide a clear description of the blockchain and the properties you've set.

5. Wait for Review: The maintainers will review your submission. They might ask for changes or additional information. Once everything is set, your contribution will be merged, and the new chain will be supported!

Your contributions are greatly appreciated and help make this tool more versatile and useful for everyone!

Each chain JSON file is structured to provide essential information about the blockchain and how the wallet addresses are generated and formatted. Here's a detailed explanation of each field:

• title: The full, readable title of the blockchain.
• network: The type of network or protocol the blockchain follows (e.g., EVM for Ethereum-compatible chains).
• startsWith: The set of characters that the wallet address typically starts with.
• prefixTest: A regular expression pattern that tests for valid characters that can appear in the prefix of a wallet address.
• apps: An array of supported wallet applications that can be used with the generated addresses.
• flags: An array of supported features for the wallet generation. Common flags include m for mnemonic support, n for generating multiple wallets, p for prefix support, and s for suffix support.
• formats: (Optional) An object defining multiple wallet formats if the blockchain supports more than one format. Each format should specify its unique properties.

By following this structure, the cryptowallet-cli tool can understand and support wallet generation for a wide array of blockchains.

Feel free to contribute by adding support for more chains, and help in making cryptowallet-cli a more comprehensive tool for the crypto community!
