Understand the project

Practical overview

When it fits

Use the library when building Rust-based desktop or mobile wallet integration, or the CLI when you need the documented local issuer-import workflow for Bitcoin and Lightning.

Who it is for

  • Wallet developers adding RGB contract support to desktop or mobile applications.
  • Rust developers integrating RGB through the client-facing library.
  • Developers using a local CLI to initialize RGB data and import contract issuers.

Documented uses

  • Integrate RGB contract functionality into a wallet or desktop application.
  • Initialize local RGB data and import issuer files through the CLI.
  • List imported contract issuers from the command line.
Before you choose

Requirements & limits

The repository is public and identifies an Apache-2.0 license. CLI installation is documented through Cargo.

  • The library and CLI serve different development needs: application integration versus local command-line operations.
  • The CLI requires an Electrum server.
  • The documented setup requires Cargo and OS-specific developer components; the minimum Rust compiler version is listed in Cargo.toml.
  • The repository states that it supports Bitcoin and Bitcoin protocols, not other blockchains.

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

Initialize RGB data and import contract issuers

Set up the CLI data directory, import issuer files, and check that the issuers are listed.

Before you start

  • Install Cargo and the repository’s OS-specific developer components.
  • Install the RGB command-line utility with cargo install rgb-wallet.
  • Have contract issuer files available locally; the README names issuer repositories and rgbex.io as possible sources.

Steps

  1. Run rgb init to initialize the data directory.

  2. Run rgb import , replacing ` with the issuer-file path; the README also describes using a wildcard such as *.issuers`.

  3. Run rgb contracts --issuers and check that the imported issuers are present.

Expected outcome

The CLI lists the imported issuers.

Guide limitations

  • The CLI requires an Electrum server.
  • The repository describes support for Bitcoin and Bitcoin protocols, not other blockchains.
