HDWallet

Generate mnemonic

const phrase = TsWalletCore.HdWallet.generateMnemonic()
console.log(phrase) // control sock axis field icon jewel gown duck amateur type step save

Generate all key pairs

const phrase = 'control sock axis field icon jewel gown duck amateur type step save'
const password = ''
const wallet = new TsWalletCore.HdWallet(phrase, password)

const derivationIndex = 0;
const currencies = wallet.generateAllKeyPairs(derivationIndex)
console.log(currencies)

Transaction Example

You can find an example how to sign transactions for different blockchains here

// TsWalletCore.MnemonicDescriptor or private key
const privateKey = '04e17ebf3b33a81a98ee779e50b725e03bbbacaca689c9f02a465800dd955e7c';

// transaction parameters (specific almost for each blockchain)
const params: TsWalletCore.TransactionParams = {
  toAddress: '0x6f387b7d5FA35a874218128E778F568294069e4C',
  amount: '0.00059655',
  nonce: 342,
  gasPrice: 7200000000,
  gasLimit: 21000
};
const blockchain = TsWalletCore.Ethereum(privateKey);
const signedTx = blockchain.signTransaction(params)
  .then(console.log)
