Bitgesell WBGLBridge SDK

This is a wrapper around the WBGL bridge for use on the Nodejs backend and Browsers written in TypeScript.

NB: To access the Bridge, we recommend visiting 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:

Initialization

import { ethers } from 'ethers'

import {
  ChaindIds,
  ChainNames,
  IBridgeConfig,
  WBGLBridgeSDK
  BGLWBGLExchangePair,
  WBGLBGLExchangePair,
} from 'wbgl-bridge-sdk'

  const bscProvider = 'https://rpc.ankr.com/bsc'
  const provider = new ethers.providers.JsonRpcProvider(bscProvider)
  const evmPrivateKey = process.env.EVM_PRIVATE_KEY
  const signer = new ethers.Wallet(evmPrivateKey, provider)
  const bnbAddress = await signer.getAddress()

const config: IBridgeConfig = {
  evmPrivateKey: evmPrivateKey, // Arbitrum, BNB chain, Ethereum privateKey etc
    provider: provider,
    chainName: ChainNames.Ethereum,
    chainId: ChaindIds.Ethereum,
    bridgeEndpoint: 'https://bglswap.com/app/',
    bglPrivateKeyOrSeed: process.env.BGL_PRIVATEKEY_OR_SEED
}

const WBGLBridgeSDKInstance = new WBGLBridgeSDK(config)

Using commonjs require:

const {
  ChainNames,
  WBGLBridgeSDK,
  ChaindIds
} = require('wbgl-bridge-sdk')

const { ethers } = require('ethers')
// for env secrets:
const dotenv = require('dotenv')
  const bscProvider = 'https://rpc.ankr.com/bsc'
  const provider = new ethers.providers.JsonRpcProvider(bscProvider)

  const evmPrivateKey = process.env.EVM_PRIVATE_KEY
  console.log(evmPrivateKey)
  const signer = new ethers.Wallet(evmPrivateKey, provider)
  const bnbAddress = await signer.getAddress()

  const config = {
    evmPrivateKey: evmPrivateKey, // Arbitrum, BNB chain, Ethereum privateKey etc
    provider: provider,
    chainName: ChainNames.Ethereum,
    chainId: ChaindIds.Ethereum,
    bridgeEndpoint: 'https://bglswap.com/app/',
    bglPrivateKeyOrSeed: process.env.BGL_PRIVATEKEY_OR_SEED
  }
  const wbglBridgesdkInstance = new WBGLBridgeSDK(config)

Swap methods

1. Swap WBGL Tokens for BGL

// address to receieve bgl from

const bglAddress = 'bgl1qh3tsz3a7l3m49xaq4xcdx8aefthchuqagmspcn' 

const wbglPair: WBGLBGLExchangePair = {
  bglAddress: bglAddress,
  wbglAmount: 5
}
const swapResult = await WBGLBridgeSDKInstance.swapWBGLforBGL(wbglPair)
console.log(swapResult)

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

const blgAmountToSwap = 1 // 1BGL
const bglTxFee = 0.0001 // A minimum txFee of proposed 10,000 satoshis(0.0001BGL)

const recepientBNBAddress = '0x309C7057d20EC9EB67b21005972fF19965483Fbf'

const bGLWBGLExchangePair: BGLWBGLExchangePair = {
  recepientWBGLAddress: recepientBNBAddress,
  bglAmount: blgAmountToSwap,
  bglFee: bglTxFee
}

const swapResult = await BGLInstance.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(currently in Beta!) with implemented functions as follows:

API

The following methods have been implemented and tested with coverage on Ethereum and BNBSmartChain:

• [x] getBalanceBGL()

• [x] getBalanceEthereum)

• [x] getBalanceBNBChain()

• [x] getBalanceArbitrumChain()

• [x] getBalanceOptimismChain()

• [x] swapBGLforBGL(bGLWBGLExchangePair: BGLWBGLExchangePair)

• [x] swapWBGLToBGL(wBGLBGLExchangePair: BGLWBGLExchangePair)

• [] getContracts()

• [] getBridgeHealth()

• [] getBridgeStatus()
