# What’s the change address

Bitcoin's wallet is built on the Hierarchical Deterministic framework, which supports generating different addresses and managing addresses.

The change address is also a subaddress generated by the mnemonic and the specific path, which is essentially a subaddress. Using subaddresses can provide users with better anonymity and privacy.
