# HD wallet

## Definition

An HD wallet, or hierarchical deterministic wallet, derives a structured family of keys and addresses from root seed material instead of requiring an unrelated backup for every new key.

## What it means in practice

The model makes backup and account generation more manageable, but exact restoration still depends on derivation paths, account indexes and address conventions.

## How this concept appears in Terenval Wallet

Terenval's create/import model follows the practical HD-wallet idea that one recovery basis can recreate supported wallet accounts, subject to compatibility rules.

**Important:** Back up the recovery material, not just screenshots of current receiving addresses.
