LNP/BP Library

LNP/BP Library is a collection of Rust crates implementing selected LNP/BP specifications for Bitcoin and Lightning Network development. Its components provide Bech32 encoding for client-side-validated data, chain parameters for Bitcoin-related blockchains, and Secp256k1-based ElGamal encryption.

Practical overview

When it fits

Use it when developing Rust software for Bitcoin or Lightning that needs one or more of the repository’s specified encoding, chain-parameter or encryption components.

Who it is for

  • Rust developers building Bitcoin or Lightning Network protocols and applications.
  • Developers who need the documented LNPBP-14 encoding, Bitcoin-related chain parameters or LNPBP-31 ElGamal implementation.

Documented uses

  • Encode client-side-validated data with the LNPBP-14 Bech32 implementation.
  • Use supplied chain parameters in Bitcoin-related applications.
  • Apply the LNPBP-31 ElGamal implementation using Secp256k1.
  • Build Bitcoin and Lightning layer 2 or layer 3 software from library components.
Before you choose

Requirements & limits

The public repository identifies the project as MIT-licensed.

  • This is a library collection for software development, rather than a ready-made node or end-user application.
  • The repository documents Rust 1.59.0 as its minimum supported compiler version for the local build instructions.
  • The stated scope is Bitcoin and Bitcoin protocols; the README says altcoins and other blockchains are not supported or planned.
  • Other client-side-validation, Bitcoin, Lightning, RGB and invoicing libraries are listed as separate projects, not included in this crate.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Add LNP/BP crates to a Rust project

Declare the documented LNP/BP crates as Cargo dependencies.

Before you start

  • A Rust project using Cargo.

Steps

  1. Add the desired lnpbp crate entries to the [dependencies] section of Cargo.toml.

  2. Use the documented ~0.5.0 version requirement for each selected crate.

Expected outcome

The project manifest declares the selected LNP/BP crates as dependencies.

Guide limitations

  • This covers dependency declaration only; the README does not provide an implementation example or verify a consuming project build.
  • The documented dependency versions are ~0.5.0.

Clone and build the library workspace

Compile the LNP/BP library workspace locally using the repository’s documented build command.

Before you start

  • Rust compiler version 1.59.0 or later.
  • Git and Cargo, as required by the documented clone and build commands.

Steps

  1. Clone https://github.com/lnp-bp/rust-lnpbp.

  2. Change into the rust-lnpbp directory.

  3. Run the command below.

    Documented command
    cargo build --release --all-features

Expected outcome

The README says the built library can be found in `target/release`.

Guide limitations

  • The instructions describe a build procedure, not a verified build result.
  • The README separately documents cargo test --workspace --all-features for running the full test suite; this guide does not cover test execution.
