Ethereum: Notify when new transaction is arrive in a bitcoin address [duplicate]

Ethereum and Bitcoin are two different cryptocurrencies, but I will give you an answer related to your question about receiving a notification when a new Ethereum transaction arrives at a Bitcoin address.

Notification of Incoming Ethereum Transactions to Bitcoin Address

To do this, we need to use the Interplanetary File System (IPFS) or similar decentralized data storage solution. IPFS allows us to store files and exchange them on different nodes without relying on central servers.

Here are two possible approaches:

Approach 1: Using IPFS for Ethereum Transactions

You can use the ethers.js library, which provides an interface to interact with the Ethereum blockchain. You can create a function that listens for incoming Ethereum transaction notifications and updates your Bitcoin address when a new transaction arrives.

First, install ethers.js and import it into your code:

const ethers = require('ethers');

const ipfs = require('ipfs');


// Create a new IPFS client

const ipfsClient = new ipfs.Client();


async function notifyNewTransaction() {

  // Get the Bitcoin address from the Ethereum transaction data

  const bitcoinAddress = transaction.data.address;


  // Update your bitcoin address on the server when a new transaction arrives

  ipfsClient.add(bitcoinAddress).then((hash) => {

    console.log(Updated new bitcoin address: ${hash});

  });

}

Then you must call this function every time you receive an Ethereum transaction. You can do this by using the web3 library or by periodically polling the IPFS server.

Approach 2: Using a Decentralized Notification Service

Another approach is to use a decentralized notification service such as Bitmessage or Matrix. These services allow users to send notifications to specific addresses, including bitcoin addresses.

You can create a new user in one of these services and add your Ethereum address as a notification endpoint. Then, when you receive incoming Ethereum transaction data, you can use the service’s API to notify your Bitcoin address.

For example, with Bitmessage:

const bitmessage = require('bitmessage');


// Create a new Bitmessage user

const user = await bitmessage.createUser({

  name: 'Your name',

  email: "your.email@example.com"

});


// Add your Ethereum address as a notification endpoint

user.endpoint = '

Then, whenever you receive incoming Ethereum transaction data, you can use the “bitmessage” API to notify your Bitcoin address:

const bitcoinAddress = transaction.data.address;

bitmessage.send(user.endpoint, {message: bitcoinAddress});

Remember to replace example.com with the actual Bitmessage server URL.

Note. Both approaches require full access to the IPFS node or server. If you don’t have either, you may have to use the second solution. Also, keep in mind that decentralized notification services can be slow and unreliable, so it’s extremely important to thoroughly test your implementation before deploying it to production.
