Title:
Unable to initiate a smart contract (BUSD) on Android Chromeu using web3js and Walletconnect
Introduction
As a web developer, I have met several challenges when building decentralized applications (DAPPS) that rely on blockchain technology. One of the usual problems is to start smart contracts using Web3Js and Walletconnect on mobile devices like Android Chrome. In this article, we will explore the reasons behind this restriction and provide a bypass solution to launch and start our Buss (Binance Smart chain) method on Android Chrome.
Why can’t I start smart contract methods
There are several reasons why smart contract methods may not work as expected while using web3Js and Walletconnect on Android Chrome:
- Web3.JS library compatibility : Web3js Library is designed to work with Ethereum blockchain seams, which is a different network from a smart chain (BSC) binance. As a result, some of the features and functionality available on the web3.Js may not be compatible or functional on BSC.
- WalletConnect Integration **: WalletConnect is an open code protocol that allows users to connect their wallets to DAPPS. However, integrating with web3js can be complex, especially when dealing with different blockchain networks.
bypass solution: Using Localhost wallet and web3.js
To get our Busd transfer method that works on Android Chrome, we will use a combination of the following tools:
- Localhost wallet : We will make a local wallet that imitates the behavior of the Binnish cash wallet. This will allow us to communicate with BSC Blockchain from the browser.
- ** web
A guide for step by step
Here’s a detailed guide to make our BUSD transfer method work on Android Chrome:
- Make a local wallet : Create a local BSC wallet supporting the chain
Ethernaut
(Equivalent Ethereum -a Binance Smart Chain). You can find pre -configured wallets online or use a tool such as a metamic to make.
- Install web3.JS : Install Web3.JS on your Localhost using NPM:
NPM install web3
.
- Create a new javascript file : Create a new file (eg,
BSSC-TRANFER.JS
) and introduce the necessary libraries:Import of Web3 from 'Web3'; Import WalletConnect of 'WalletConnect';
- Set Localhost Wallet : Replace the following holdings with your actual URL -Localhost wallet:
Javascript
Const W3 = New Web3 (new web3providers.httpprovider (‘http: // Localhost: 8545’);
`
- Create a smart contract method : Create a new javascript file (eg,BSSC-TRANFER.JS
) and define the methods of a smart contract you want to execute.
- Use WalletConnect : Use an instanceWalletconnect
to connect your Localhost wallet and start a smart contract method.
Example Code
Here's an example of a code clip to start:
Javascript
Const W3 = New Web3 (new web3providers.httpprovider (‘http: // Localhost: 8545’);
// Set up a local wallet connection
Constalletrol = ‘https: // Localhost: 8545’;
ConstalletPrivatekey = ‘Your-Wallet-Private-Chey’;
// Create a smart contract methods
Async Function Transferbusd (amount) {{
Wait W3.esth.send transaction ({{
From: process.env.
to: ‘0x … yourRecipientaddress’,
Value: amount * 10 // 100 Busd by transaction
});
Iche
// Use an instance of Walletconnect to start a smart contract method
Const wallet = new Walletconnect ({{
Providerurl: Waleturl,
Chainid: 42, // BSC Mainnet
Accounts: [… Yourwalletaddress’]
});
Wallet.on (‘Connect’, (Lank) => {
console.
