import the mnemonic seed to fuel official wallet , get result

if you export private key from wallet, you will get same result

last but important!

  1. test the result and compare it with main web wallet app(such as: metamask, mathwallet, trustwallet...) before you deposit crypto assets to the address
  2. some wallet may get diffrent result, because it may use diffrent derive path to generate wallet
  3. learn about hd-wallet principle by your self
