Ethereum and Bitcoin are two different cryptocurrencies, but I will give you an answer that will address your question about being notified when a new Ethereum transaction is received at a Bitcoin address.

Notifying incoming Ethereum transactions at a Bitcoin address

To achieve this, we need to use the InterPlanetary File System (IPFS) or a similar decentralized storage solution. IPFS allows us to store and share files across multiple 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 is received.

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 Bitcoin address from Ethereum transaction data
const bitcoinAddress = transaction.data.address;
// Update your Bitcoin address on the server when a new transaction is received
ipfsClient.add(bitcoinAddress).then((hash) => {
console.log (New Bitcoin address updated: ${hash});
});
}

Then this function should be called every time an Ethereum transaction is received. This can be done 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 on one of these services and add your Ethereum address as a notification endpoint. Then, whenever 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 your actual Bitmessage server URL.

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