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 { SingleKey, Wallet } from "@arkade-os/sdk";

// Create an identity (private key)
const identity = SingleKey.fromHex("your-private-key-hex");
// Or generate a new one:
// const identity = SingleKey.fromRandomBytes();
