Understand the project

Practical overview

When it fits

Use Libauth when implementing Bitcoin-family functionality in a JavaScript or TypeScript application that can use its functions in Node.js, Deno, or a browser.

Who it is for

  • JavaScript and TypeScript developers building Bitcoin Cash, Bitcoin, or Bitauth applications.
  • Developers who need library functions for cryptography, keys, addresses, transaction verification, or wallet and transaction creation.

Documented uses

  • Add cryptographic operations such as secp256k1 signature verification to an application.
  • Work with Bitcoin-family keys and address formats.
  • Verify transactions or create wallet transactions using library functionality.
Before you choose

Requirements & limits

  • The library has no dependencies of its own and documents support for Node.js, Deno, and browsers.
  • Its functional design exposes lower-level functions that can be combined into higher-level behavior.
  • The repository links to installation documentation and an API reference, with separate guides for cryptography, keys, addresses, transaction verification, and wallet and transaction creation.
  • The repository specifies the MIT license.

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

Install Libauth and import a function

Add the library to a JavaScript or TypeScript project and import selected functionality.

Before you start

  • A JavaScript or TypeScript project using npm or Yarn.

Steps

  1. Install the package with the command below or yarn add @bitauth/libauth.

    Documented command
    npm install @bitauth/libauth

  2. Import the required functionality from @bitauth/libauth; the README demonstrates importing secp256k1.

Expected outcome

The project has Libauth installed and can import its selected functions.

Guide limitations

  • This setup guide does not cover a complete application workflow or provide a transaction, key, or wallet implementation.
