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

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)

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',

}
This library is in active development(currently in Beta!) with implemented functions as follows:
The following methods have been implemented and tested with coverage on Ethereum
and BNBSmartChain
:
getBalanceBGL()
getBalanceEthereum)
getBalanceBNBChain()
getBalanceArbitrumChain()
getBalanceOptimismChain()
swapBGLforBGL(bGLWBGLExchangePair: BGLWBGLExchangePair)
swapWBGLToBGL(wBGLBGLExchangePair: BGLWBGLExchangePair)
[] getContracts()
[] getBridgeHealth()
[] getBridgeStatus()
For more in-depth information on the SDK's methods, classes, and usage, refer to the official documentation.
Note: For a complete example see /examples/
Note: Provider appropriate EVM Node RPC and PrivatKey for respective networks eg: Ethereum RPC node and Ethereum private key
