Ethereum: How to View All Addresses in HD Wallet
As an Ethereum developer, you are probably interested in monitoring your HD wallet activity, especially when it comes to receiving Bitcoin (BTC). While the Bitcoind wallet notification service only supports traditional HD wallets, such as Electrum or MetaMask, there are alternative solutions that allow you to receive notifications for addresses under HD wallets. In this article, we will look at how to achieve this.
Why do I need to view all addresses in HD Wallet?
HD wallets use hardware security modules (HSMs) to securely store your private Ethereum keys on the device. These HSMs are designed to protect sensitive data and can only use the key corresponding to a specific address. Using an address to receive BTC does not automatically notify your HD wallet or any other service of your actions.
How to see all addresses in HD Wallet?
While Bitcoind’s wallet notification service (walletnotify) supports traditional HD wallets, there are alternative solutions available:
- Etherscan
: Etherscan is a popular platform for Ethereum developers to monitor their accounts and receive notifications when certain addresses are used to receive BTC.
- HD Wallet Notification Service
: There is an unofficial HD Wallet notification service called “Wallet Notify” (also known as “walletnotify”) that supports HD wallets like Electrum, MetaMask, and others. However, it is important to note that this service only works with traditional HD wallets, not the original HD wallets.
- Ethereum Smart Contracts: You can also create a custom notification system for your HD wallet using Ethereum smart contracts.
Introducing the HD Wallet Notification Service
To enable the HD Wallet Notification Service using Etherscan, you need to do the following:
- Install Etherscan on your device or server.
- Create an account and obtain an API key from Etherscan.
- Use the Etherscan API to retrieve information about your Ethereum accounts, including HD wallet addresses.
Here is a simple example of how you can use the Etherscan API to receive notifications when certain addresses are used to receive BTC:
const etherscanApi = request('etherscan-api');
// Replace the Etherscan API key with the wallet address
const apiKey = 'YOUR_API_KEY';
const walletAddress = 'YOUR_WALLET ADDRESS';
// Get information about Ethereum accounts, including HD wallet addresses
etherscanApi.getAccounts(wallet address)
.then(accounts => {
accounts.forEach(account => {
if (account.address.includes('HD Wallet')) {
console.log(Notification received for address: ${account.address});
}
});
})
.catch(err => {
console error (err);
});
Conclusion
While traditional HD wallets such as Electrum and MetaMask only support Bitcoind’s wallet notification service, there are alternative solutions that allow you to receive notifications when HD wallet addresses are used to receive BTC. By enabling the HD Wallet Notification Service with Etherscan or creating your own custom solution, you can keep track of your Ethereum accounts and receive timely notifications about activities.
