hd-key-deriver

A simple Node.js utility that derives hierarchical deterministic (HD) keys from a 12-word or 24-word mnemonic using Ethers.js v6.

🚀 Features

• Uses Ethers.js v6 for HD wallet derivation.
• Supports 12-word and 24-word mnemonics.
• Derives the first 10 Ethereum addresses and private keys.
• Uses the standard BIP44 Ethereum derivation path (m/44'/60'/0'/0/i).

📦 Installation

Ensure you have Node.js installed, then run:

npm install

🔧 Usage

Run the script by passing a 12-word or 24-word mnemonic:

npm start -- test test test test test test test test test test test junk

📜 Example Output

0 | 0xAbC123... | 0x1234abcd...
1 | 0xDef456... | 0x5678efgh...
2 | 0xGhi789... | 0x9101ijkl...
...

📌 Notes

• Never share your mnemonic or private keys!
• Modify deriveChild(i) if you need a different range of addresses.
• This utility is intended for development and learning purposes.
