Library for building descriptor-based bitcoin wallets. Everything a modern read-only bitcoin wallet needs, but which is not (yet) a part of rust-bitcoin library.
NB: The library does not work with private keys; it is advised that wallets will be designed in a way assuming zero private key access for all of their operations aside from transaction signing; this part must be separated into other repository/library and be strictly controlled.
This library previously was a part of LNP/BP Core Library.
Library components: - More efficient manipulations with BIP-32 derivation paths - Universal miniscript/classical bitcoin descriptors - Script templates allowing embedding extended pubkeys into bitcoin script assembly - Lexicographic ordering of transaction & PSBT inputs & oututs - Script type system - Helper types for working with hash-lock contracts - PSBT utility functions (retrieving previous output, computing fee)
Includes separate crate for SLIP-132 functionality in /slip132
subdirectory.
