BIP44 HD wallets, explained

Every payment on Bixmerchant lands in a unique address. That is not a gimmick — it is how hierarchical deterministic (HD) wallets work, and it keeps your customers' transaction history private while simplifying reconciliation on your side.

We follow BIP39 for the recovery phrase and BIP32/BIP44 for the derivation path m/44'/{coin}'/0'/0/{index}. From a single account-level extended public key (xpub), we can derive an unlimited sequence of child addresses without ever holding the corresponding private keys.

In auto mode, Bixmerchant generates a recovery phrase, shows it to you once, and stores only encrypted account-level xpubs. Addresses are then derived on demand using non-hardened child-key derivation, so the server never needs your seed to issue new payment addresses.

Because the scheme is standards-compliant, your wallet is portable. If you ever decide to leave, you can recover the full balance from your phrase using any BIP44-compatible wallet.
