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(); const wallet = await Wallet.create({ identity, arkServerUrl: "https://arkade.computer", }); const address = await wallet.getAddress(); console.log("Ark Address:", address); For production, always use a secure key management solution rather than hardcoded keys.
Addresses
// Offchain Ark address (ark1.../tark1...) — for instant payments const arkAddress = await wallet.getAddress(); // Boarding address — for receiving onchain BTC to be onboarded later const boardingAddress = await wallet.getBoardingAddress();
Balances
const balance = await wallet.getBalance(); console.log("Available:", balance.available, "sats"); // spendable now console.log("Total:", balance.total, "sats"); // includes recoverable console.log("Settled:", balance.settled, "sats"); // Bitcoin-anchored console.log("Preconfirmed:", balance.preconfirmed, "sats"); // cosigned // Pending onchain deposits console.log("Boarding:", balance.boarding.total, "sats");
Sending Payments
// Send to an Ark address — instant, near-zero fees const txid = await wallet.sendBitcoin({ address: "ark1...", amount: 50000, // satoshis }); For onchain destinations (bc1.../tb1...), use the Ramps offboard flow below. For Lightning invoices, use @arkade-os/boltz-swap.
Receiving Payments
const address = await wallet.getAddress(); // Share this address with the sender // Monitor for incoming funds const stop = wallet.notifyIncomingFunds(async (notification) => { if (notification.type === "vtxo") { for (const vtxo of notification.vtxos) { console.log(`Received ${vtxo.amount} sats`); } } }); // Call stop() when done listening
VTXOs
const vtxos = await wallet.getVtxos(); for (const vtxo of vtxos) { console.log(vtxo.txid, vtxo.amount, vtxo.status); }
Onchain Ramps (Onboard / Offboard)
Convert between onchain Bitcoin UTXOs and offchain Arkade VTXOs. Best for large transfers; for everyday amounts, Lightning swaps have lower overhead. import { Ramps } from "@arkade-os/sdk"; const ramps = new Ramps(wallet); // Get fee info from the Ark server const info = await wallet.arkProvider.getInfo(); // Onboard: convert boarding UTXOs to VTXOs const commitmentTxid = await ramps.onboard(info.fees); // Offboard: convert VTXOs to onchain BTC const exitTxid = await ramps.offboard( "bc1q...", // destination onchain address info.fees, // amount, // optional — defaults to all available );
Lightning Network
npm install @arkade-os/boltz-swap Lightning integration uses Boltz submarine swaps to bridge between Arkade and the Lightning Network. import { ArkadeLightning, BoltzSwapProvider } from "@arkade-os/boltz-swap"; const swapProvider = new BoltzSwapProvider({ apiUrl: "https://api.ark.boltz.exchange", network: "bitcoin", }); const lightning = new ArkadeLightning({ wallet, swapProvider, }); // Receive via Lightning (reverse swap) const { invoice, paymentHash } = await lightning.createLightningInvoice({ amount: 25000, }); console.log("Pay this:", invoice); // Send via Lightning (submarine swap) const result = await lightning.sendLightningPayment({ invoice: "lnbc...", }); console.log("Preimage:", result.preimage);

Skill Classes (this package)
This package (@arkade-os/skill) provides higher-level wrapper classes over the SDK: npm install @arkade-os/skill import { Wallet, SingleKey } from "@arkade-os/sdk"; import { ArkadeBitcoinSkill, ArkaLightningSkill, LendaSwapSkill, } from "@arkade-os/skill"; const wallet = await Wallet.create({ identity: SingleKey.fromHex(privateKeyHex), arkServerUrl: "https://arkade.computer", }); // Bitcoin: addresses, balances, send/receive, onboard/offboard const bitcoin = new ArkadeBitcoinSkill(wallet); const balance = await bitcoin.getBalance(); await bitcoin.send({ address: "ark1...", amount: 50000 }); // Lightning: invoices, payments via Boltz const lightning = new ArkaLightningSkill({ wallet, network: "bitcoin" }); const inv = await lightning.createInvoice({ amount: 25000 }); // Stablecoin swaps: BTC <-> USDC/USDT const lendaswap = new LendaSwapSkill({ wallet }); const quote = await lendaswap.getQuoteBtcToStablecoin(100000, "usdc_pol");
ArkadeBitcoinSkill
getArkAddress() / getBoardingAddress() — get addresses getBalance() — balance breakdown (offchain + onchain) send({ address, amount }) — send sats offchain getTransactionHistory() — transaction list onboard(params) / offboard(params) — onchain ramps waitForIncomingFunds(timeout?) — wait for incoming payment
ArkaLightningSkill
createInvoice({ amount, description? }) — Lightning invoice (reverse swap) payInvoice({ bolt11 }) — pay Lightning invoice (submarine swap) getFees() / getLimits() — swap fees and limits getPendingSwaps() / getSwapHistory() — swap tracking
LendaSwapSkill
getQuoteBtcToStablecoin(amount, token) / getQuoteStablecoinToBtc(amount, token) swapBtcToStablecoin(params) / swapStablecoinToBtc(params) getSwapStatus(swapId) / getPendingSwaps() / getSwapHistory() claimSwap(swapId) / refundSwap(swapId) getAvailablePairs()
Stablecoin Swaps (LendaSwap)
Non-custodial BTC/stablecoin atomic swaps via HTLCs. Supported tokens: usdc_pol, usdc_eth, usdc_arb, usdt0_pol, usdt_eth, usdt_arb Supported chains: polygon, ethereum, arbitrum 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 (BTC -> USDC) const swap = await lendaswap.swapBtcToStablecoin({ targetAddress: "0x...", // EVM address targetToken: "usdc_pol", targetChain: "polygon", sourceAmount: 100000, }); console.log("Swap ID:", swap.swapId); // Check status const status = await lendaswap.getSwapStatus(swap.swapId); // Claim completed swap const claim = await lendaswap.claimSwap(swap.swapId);
Smart Contracts
Arkade supports any valid Tapscript as VTXO locking conditions, enabling programmable offchain Bitcoin. npm install @arkade-os/sdk @scure/base import { RestArkProvider, RestIndexerProvider, SingleKey, VtxoScript, MultisigTapscript, CSVMultisigTapscript, } from "@arkade-os/sdk"; import { hex } from "@scure/base"; const arkProvider = new RestArkProvider("https://mutinynet.arkade.sh"); const indexerProvider = new RestIndexerProvider("https://mutinynet.arkade.sh"); const info = await arkProvider.getInfo(); const serverPubkey = hex.decode(info.signerPubkey).slice(1); Available contract primitives: MultisigTapscript — N-of-N multisig CLTVMultisigTapscript — Multisig with absolute timelocks CSVMultisigTapscript — Multisig with relative timelocks VtxoScript — Combine spending paths into Taproot trees Contract patterns in docs: HTLC/Hashlock, Escrow (3-path), Spilman channels, Dryja-Poon channels, Lightning channels, chain swaps, Oracle DLC. Use @scure/base for encoding, NOT bitcoinjs-lib. See: https://docs.arkadeos.com/contracts/overview

Key Concepts
VTXOs: Virtual Transaction Outputs — self-custodial offchain Bitcoin coins. States: preconfirmed, settled, recoverable, spent. Batch Swaps: How VTXOs achieve Bitcoin finality — multiple transactions batched into a single onchain settlement. Preconfirmation: Instant confirmation cosigned by the operator, before onchain settlement. Virtual Mempool: DAG-based offchain execution engine that processes Arkade transactions. Unilateral Exit: Users can always withdraw their funds onchain without operator cooperation. Ark Addresses: ark1... (mainnet) / tark1... (testnet) — bech32m-encoded addresses containing server + user keys.
