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);
