Tatum supports BIP44 HD wallets. Because they can generate 2^31 addresses from 1 mnemonic phrase, they are very convenient and secure. A mnemonic phrase consists of 24 special words in a defined order and can restore access to all generated addresses and private keys.  
Each address is identified by 3 main values:

*   Private Key - your secret value, which should never be revealed
*   Public Key - public address to be published
*   Derivation index - index of generated address

Tatum follows BIP44 specification and generates for Bitcoin wallet with derivation path m'/44'/0'/0'/0. More about BIP44 HD wallets can be found here - [https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki](https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki).
