Key Derivation BIP-44 HD key derivation paths
The Lux wallet uses hierarchical deterministic (HD) key derivation following BIP-32/BIP-44 standards. A single BIP-39 mnemonic generates all keys across all chain types.

Index 0 is the default key
On P-Chain, index 0 may be locked if listed in initialStakedFunds in genesis
Use index 1+ for unlocked operational keys
