cosmos-atom-hdwallet

cosmos-atom-hdwallet is a Node.js package that provides a DirectSecp256k1HdWallet implementation for Cosmos-SDK-based blockchains. It allows you to generate and manage hierarchical deterministic (HD) wallets.

Installation

The package can be installed using npm:

npm install cosmos-atom-hdwallet

Usage

To use cosmos-atom-hdwallet, import DirectSecp256k1HdWallet from the package, and create an instance of the wallet using a mnemonic phrase and a derivation path. You can then use the wallet to sign transactions and retrieve the account address and private key.

const { DirectSecp256k1HdWallet } = require('cosmos-atom-hdwallet')

async function atom() {
  const derivationPath = "m/0'/0"
  const mnemonic = "profit oppose submit bunker faculty load alpha innocent umbrella boil cargo stomach";
  const wallet = await DirectSecp256k1HdWallet.fromMnemonicToWallet(mnemonic, derivationPath)
  const [account] = await wallet.getAccountsWithPrivkeys();
  const address = account.address
  const wif = Buffer.from(account.privkey).toString('hex')
  console.log({ address: address, privateKey: wif })
}
