Arkade SDK Development Guide

Arkade is a programmable Bitcoin execution layer. It uses VTXOs (Virtual Transaction Outputs) to enable instant offchain Bitcoin transactions with near-zero fees, while users retain full self-custody and unilateral exit rights. No changes to Bitcoin are required.

SDK Installation & Setup

npm install @arkade-os/sdk

Requires Node.js >= 22.

import { generateMnemonic } from "@scure/bip39";
import { wordlist } from "@scure/bip39/wordlists/english";
