Online tool to check balances of HD addresses given a public master key?

[lukaexpl]

Is there such a tool?

Meaning if I enter my master public key to derive the addresses and show me balances?
Monitoring of cold storage would be the intended use.

You can create a "watch only" wallet with electrum with the xpubkey. If you truly wanted to use a website, you can enter the xpubkey in the search box and it will display all the transactions associated with that key.

You can watch the addresses associated with an xpub key by using blockchain.info. Either by using blockchain.info's search function, or by directly accessing the link like so: blockchain.info/xpub/xpubYOURPUBLICKEY

Alternatively you can create a "watch only" wallet by importing the xpub key to Mycelium on mobile. That would be pretty much the same solution as Electrum mentioned above, just on mobile instead of desktop.

Thank you for repeating exactly what I posted in your own words. I am glad to see the signature spam has made its way into the technical portion of the forum. /s

I pointed out a mobile wallet alternative to Electrum. Also you simply wrote "you can enter the xpubkey in the search box" without even mentioning a site. Unless you can find the list of transactions using Bitcointalk's search function :p

I thank you both regardless of signature. I am richer in knowledge for your contributions.
