Minimum Supported Rust Version: 1.29.0

This crate uses "2015" edition and won't be ported over "2018" edition in the near future as this will change the MSRV to 1.31.


Library for handling Miniscript, which is a subset of Bitcoin Script designed to support simple and general tooling. Miniscripts represent threshold circuits of spending conditions, and can therefore be easily visualized or serialized as human-readable strings.

High-Level Features

This library supports

  • Output descriptors including embedded Miniscripts
  • Parsing and serializing descriptors to a human-readable string format
  • Compilation of abstract spending policies to Miniscript (enabled by the compiler flag)
  • Semantic analysis of Miniscripts and spending policies, with user-defined public key types
  • Encoding and decoding Miniscript as Bitcoin Script, given key types that are convertible to bitcoin::PublicKey
  • Determining satisfiability, and optimal witnesses, for a given descriptor; completing an unsigned bitcoin::TxIn with appropriate data
  • Determining the specific keys, hash preimages and timelocks used to spend coins in a given Bitcoin transaction

More information can be found in the documentation or in the examples/ directory
