Bitgesell WBGLBridge SDK

This is a tiny wrapper around the WBGL bridge for use on the Nodejs backend

NB: This is highly experimental and for BGL-WBGL swaps, Recommend to use the official bridge at bglswap.com

Installation

To get started with the Bitgesell WGL Bridge SDK, you can install it using npm:

npm install wbgl-bridge-sdk

or using yarn:

yarn add wbgl-bridge-sdk

Usage

Import the SDK into your TypeScript project to start using the Bitgesell WGL Bridge functionalities:

import Web3 from 'web3'
import PrivateKeyProvider from 'truffle-privatekey-provider'
import { WBGLBridgeSDK, IBridgeConfig } from 'wbgl-bridge-sdk';

const bscProviderRpc = 'https://rpc.ankr.com/bsc'
const MNEMONIC = process.env.MNEMONIC
const bglSeedPhrase = process.env.bglSeedphrase

web3Provider = new HDWalletProvider(MNEMONIC, bscProviderRpc)

// SDK config object
const config: IBridgeConfig = {
  provider: web3Provider,
  chainName: ChainNames.BinanceSmartChain,
  chainId: ChaindIds.BinanceSmartChain,
  bridgeEndpoint: 'https://bglswap.com/app/',
  bglPrivateKey: process.env.bglPrivateKey,
  bglSeedPhrase: bglSeedPhrase
}

const accounts = await web3Instance.eth.getAccounts()
recepientBSCAddress = accounts[0] // address 0

// Instantiate the SDK with your provider
const wbglBridge = new WBGLBridgeSDK(config);


// Get bridge health:
const health = await wbglBridge.getBridgeHealth()
console.log(health) // "ok"

// Use the SDK methods to interact with the Bitgesell WBGL Bridge
const balance = await wbglBridge.getBalanceETH();
console.log(`WBGL on Ethereum balance: ${balance}`);

1. Swap WBGL Tokens for BGL

const bglAddress = '' // address to receive BGL
const amount = 200 // WBGL amount
const to = '' // BSC/ETH address to send tokens to
const res = await wbglBridge.swapWBGLforBGL(bglAddress, amount, to)

2. Swap BGL for WBGL Tokens to BSC/Ethereum address

const blgAmountToSwap = 2 // 2BGL
const bglTxFee = 0.0001 // minimum txFee of proposed 10,000 satoshis(0.0001BGL)

const bGLWBGLExchangePair: BGLWBGLExchangePair = {
  sourceWBGLAddress: recepientBSCAddress,
  bglAmount: blgAmountToSwap,
  bglFee: bglTxFee
}

const swapResult = await bGL.swapBGLforWBGL(bGLWBGLExchangePair)
console.log(swapResult)

On a sucessful swap:

{
  bglBridgeAddress: 'bgl1qsxt0ktqgxptn6qv6s4jhxe6rappvv6r342vmx3',
  currentWBGLBridgeBalance: '112020.082928590506503209',
  msg: 'You have successfully sent 1 to bgl1qsxt0ktqgxptn6qv6s4jhxe6rappvv6r342vmx3 to receive WBGL,  1 fee is charged. The currently available WBGL balance is 112020.082928590506503209. If you send more BGL than is available to complete the exchange, your BGL will be returned to your address.\n' +
  'Please note, that a fee of 1% will be automatically deducted from the transfer amount. This exchange pair is active for 7 days.',
  bglTxHash: '819eefaf783289c8220b5052ac2e4141b25948a18ee44d713d08db9dab634e0f',
  rpcResult: {
    result: '819eefaf783289c8220b5052ac2e4141b25948a18ee44d713d08db9dab634e0f',
    error: null,
    id: 'curltext'
  }
}

Roadmap

This library is in active development with implemented functions as follows:

Bridgle methods

The following methods have been implemented and tested with coverage:

• [x] getBridgeHealth()
• [x] getBridgeStatus()
• [x] getBalanceBGL()
• [x] getBalanceETH()
• [x] getBalanceBSC()
• [x] getContracts()

Swap Methods(in Development)

Swap methods for bridge functionality currently in development :

• [x] swapBGLforBGL(bGLWBGLExchangePair: BGLWBGLExchangePair)
• [x] swapWBGLforBGL(wBGLBGLExchangePair: BGLWBGLExchangePair)
