Hierarchical Deterministic (HD) Wallet

This library is still under development and not ready for production use.

A complete Hierarchical Deterministic (HD) Wallet generator for 200+ cryptocurrencies, built with TypeScript.

This library offers a flexible and scalable solution for developers integrating multi-currency wallet functionality. It adheres to standard protocols for compatibility with other wallets and services, and provides features like secure seed generation, robust key management, and streamlined account control. By simplifying blockchain interactions, it enhances the developer experience and strengthens end-user security.
For Python support, explore python-hdwallet, the original implementation of this library. Try it live at https://hdwallet.online, our interactive web playground.
