Arkade

Arkade Skill

Send and receive Bitcoin over Arkade (offchain), onchain (via onboard/offboard), and Lightning Network. Swap between BTC and stablecoins (USDC/USDT) via LendaSwap.

Payment methods:

• Offchain (Arkade): Instant transactions between Arkade wallets
• Onchain: Get paid onchain via boarding address (onboard), pay onchain via offboard
• Lightning: Pay and receive via Boltz submarine swaps

Default Server: https://arkade.computer

CLI Commands

Note: Examples below use arkade directly (assumes global install). For pnpm: pnpm dlx @arkade-os/skill <command> For npx: npx -y -p @arkade-os/skill arkade <command>

Wallet Management

# Initialize wallet (auto-generates private key, default server: arkade.computer)
arkade init

# Initialize with custom server
arkade init https://custom-server.com

# Show Ark address (for receiving offchain Bitcoin)
arkade address

# Show boarding address (for onchain deposits)
arkade boarding-address

# Show balance breakdown
arkade balance

Bitcoin Transactions

# Send sats to an Ark address
arkade send <ark-address> <amount-sats>

# Example: Send 50,000 sats
arkade send ark1qxyz... 50000

# View transaction history
arkade history

Onchain Payments (Onboard/Offboard)

# Get paid onchain: Receive BTC to your boarding address, then onboard to Arkade
# Step 1: Get your boarding address
arkade boarding-address

# Step 2: Have someone send BTC to your boarding address

# Step 3: Onboard the received BTC to make it available offchain
arkade onboard

# Pay onchain: Send offchain BTC to any onchain Bitcoin address
arkade offboard <btc-address>

# Example: Pay someone at bc1 address
arkade offboard bc1qxyz...

Lightning Network

# Create a Lightning invoice to receive payment
arkade ln-invoice <amount-sats> [description]

# Example: Create invoice for 25,000 sats
arkade ln-invoice 25000 "Coffee payment"

# Pay a Lightning invoice
arkade ln-pay <bolt11-invoice>

# Show swap fees
arkade ln-fees

# Show swap limits
arkade ln-limits

# Show pending swaps
arkade ln-pending

Stablecoin Swaps (LendaSwap)

# Get quote for BTC to stablecoin swap
arkade swap-quote <amount-sats> <from> <to>

# Example: Quote 100,000 sats to USDC on Polygon
arkade swap-quote 100000 btc_arkade usdc_pol

# Show available trading pairs
arkade swap-pairs

SDK Usage

import { Wallet, SingleKey } from "@arkade-os/sdk";
import {
  ArkadeBitcoinSkill,
  ArkaLightningSkill,
  LendaSwapSkill,
} from "@arkade-os/skill";

// Create wallet (default server: arkade.computer)
const wallet = await Wallet.create({
  identity: SingleKey.fromHex(privateKeyHex),
  arkServerUrl: "https://arkade.computer",
});

// === Bitcoin Operations ===
const bitcoin = new ArkadeBitcoinSkill(wallet);

// Get addresses
const arkAddress = await bitcoin.getArkAddress();
const boardingAddress = await bitcoin.getBoardingAddress();

// Check balance
const balance = await bitcoin.getBalance();
console.log("Total:", balance.total, "sats");
console.log("Offchain available:", balance.offchain.available, "sats");
console.log("Onchain pending:", balance.onchain.total, "sats");

// Send Bitcoin
const result = await bitcoin.send({
  address: recipientArkAddress,
  amount: 50000,
});
console.log("Sent! TX:", result.txid);

// === Lightning Operations ===
const lightning = new ArkaLightningSkill({
  wallet,
  network: "bitcoin",
});

// Create invoice
const invoice = await lightning.createInvoice({
  amount: 25000,
  description: "Coffee payment",
});
console.log("Invoice:", invoice.bolt11);

// Pay invoice
const payment = await lightning.payInvoice({
  bolt11: "lnbc...",
});
console.log("Paid! Preimage:", payment.preimage);

// === Stablecoin Swaps ===
const lendaswap = new LendaSwapSkill({ wallet });

// Get quote
const quote = await lendaswap.getQuoteBtcToStablecoin(100000, "usdc_pol");
console.log("You'll receive:", quote.targetAmount, "USDC");

// Execute swap
const swap = await lendaswap.swapBtcToStablecoin({
  targetAddress: "0x...", // EVM address
  targetToken: "usdc_pol",
  targetChain: "polygon",
  sourceAmount: 100000,
});
console.log("Swap ID:", swap.swapId);

Configuration

Data Storage: ~/.arkade-wallet/config.json

Private keys are auto-generated on first use and stored locally. They are never exposed via CLI arguments or stdout. No environment variables required. The LendaSwap API is publicly accessible.
