Getting started

yarn add @synonymdev/blocktank-client
#or
npm i -S @synonymdev/blocktank-client

Usage

import bt from '@synonymdev/blocktank-client';

// Choose network
bt.setNetwork('mainnet'); // Options are 'mainnet' and 'regtest'

// Get all node info and available services
const info = await bt.getInfo();

const service = info.services[0];

// 1. Place order
const buyRes = await bt.buyChannel({
    product_id: service.product_id,
    channel_expiry: 4,
    remote_balance: 0,
    local_balance: 20000,
});

// 2. Make payment using one of below methods
const {btc_address, ln_invoice} = buyRes;

// 3. Get order details for current state
const order = await bt.getOrder(buy.order_id);

// 4. Make an onchain transaction using the below min fee with RBF disabled to instantly be able to claim your channel
const {zero_conf_satvbyte, zero_conf_satvbyte_expiry} = order;

// Once order state === 100 a channel can be claimed
const {state, stateMessage} = order;

// For all order states see: https://github.com/synonymdev/blocktank-client/blob/f8a20c35a4953435cecf8f718ee555e311e1db9b/src/services/client.ts#L15

// 5. Claim lnurl-channel
const {lnurl_string} = order;

// Or claim manually with an additional method
try {
  await bt.finalizeChannel({
    order_id: order._id,
    node_uri: '0296b2db342fcf87ea94d981757fdf4d3e545bd5cef4919f58b5d38dfdd73bf5c9@34.79.58.84:9735',
    private: true // For mobile nodes that won't be routing transactions
  });
} catch (e) {
  console.error(e);
