 - **Pros**: the most recent type, with greater privacy and flexibility (supports complex scripts hidden behind a single address). Low fees, more efficient Schnorr signatures, signature aggregation
 - **Cons**: still relatively new, not supported by all services, higher implementation complexity
 
+### 6. HD Wallet (BIP-32/39/44/49/84/86)
+- **Standards**: BIP-32 (hierarchical deterministic wallets), BIP-39 (mnemonic phrases), BIP-44/49/84/86 (derivation paths)
+- **Networks**: mainnet, testnet
+- **Derivation paths**:
+  - BIP-44 → P2PKH: `m/44'/0'/account'/0/index` — addresses start with `1` (mainnet)
+  - BIP-49 → P2SH-P2WPKH: `m/49'/0'/account'/0/index` — addresses start with `3` (mainnet)
+  - BIP-84 → P2WPKH: `m/84'/0'/account'/0/index` — addresses start with `bc1q` (mainnet)
+  - BIP-86 → P2TR: `m/86'/0'/account'/0/index` — addresses start with `bc1p` (mainnet)
+- **Extended key prefixes**: `xpub`/`xprv` (BIP-44/86), `ypub`/`yprv` (BIP-49), `zpub`/`zprv` (BIP-84)
+- **JSON output**: compatible with Electrum wallet format (`keystore`, `xpub`, `xprv`, `derivation`, `root_fingerprint`, `seed_version: 17`)
+- **Pros**: deterministic key derivation from a single mnemonic, interoperable with Electrum and other BIP-39 compatible wallets
+- **Cons**: requires securely backing up the mnemonic phrase
+
+**Available options:**
+- Generate a new 12-word mnemonic or import an existing one
+- Optional BIP-39 passphrase
+- Account index selection
+- Configurable number of receiving addresses to derive

 ### In development
 - **P2WSH (Pay-to-Witness-Script-Hash)**: SegWit version of P2SH, more efficient and secure.
