This greatly simplifies the user's operation process while ensuring the security of assets.

The concept and principle of hierarchical deterministic wallets can be succinctly summarized in two sentences: first, the master private key is generated through random numbers, the same way other wallets generate private keys; then, using deterministic, The irreversible algorithm generates multiple sub-private keys based on the master private key.

When you create an HD wallet for the first time through Tron Link App, a set of mnemonic words will be generated. A mnemonic is a sequence of English words that can be used to create a seed from which all private keys can be derived. Therefore, the wallet can be backed up and restored through the mnemonic phrase.
