Lexe Documentation

Lexe runs self-custodial Lightning nodes in secure hardware: always online, hosted for free, and only the owner holds the keys. Lexe Wallet is the app for a personal node. The Lexe SDK creates nodes for businesses, their users, and their agents.

Wallet

Lexe Wallet is a self-custodial Bitcoin and Lightning wallet for iOS and Android. Getting Started covers setup, backup, and the first payments, and the FAQ answers common questions.

SDK

The Lexe SDK creates and controls Lexe nodes from application code. It comes in four forms:

  • Lexe CLI: create and control wallets from the command line.
  • Rust SDK: the most advanced SDK, for secure, high-performance applications.
  • Python SDK: a simple interface for any Python application, or a wallet at a Python REPL.
  • Sidecar SDK: a local REST server, for any language.

Showcase

Projects built on Lexe, from mining pools and invoicing tools to AI agents and vending machines.
