- [BIP 32 Explained: Hierarchical Deterministic Wallets](/bip-32/)  
BIP 32 defines HD wallets: one seed derives a tree of keys via chain codes and hardened or normal steps, and an xpub makes addresses without private keys.
- [BIP 44 – Multi-Account Hierarchy for Deterministic Wallets](/bip-44-multi-account-hierarchy-for-deterministic-wallets/)  
BIP-44 defines the m/purpose'/coin\_type'/account'/change/index path, letting a seed phrase manage accounts across coins like Bitcoin and Ethereum.
- [BIP 157 Client-Side Block Filtering: Compact Filters Explained](/bip-157-client-side-block-filtering/)  
BIP 157 lets light wallets fetch compact block filters (BIP 158) from full nodes and test them locally, finding their payments without revealing addresses.
