One private key corresponds always to one public key and one address. HD wallets are just a way or organizing your private keys in an easier-to-manage way.

In the end a HD wallet is just a collection of different private keys and therefore a collection of different public addresses. In order to transfer tokens (or Ethers) between different addresses you need Ethers to pay for the gas costs.


If you want to transfer ERC20 token from child to parent of hd wallet, then gas used in ETH from you child wallet.
