Looking for software to monitor bitcoin addresses

[Nathan047]

Over a little while I've accumulated a number of addresses. I don't check most of them regularly because I don't have a need for them nor do I expect payments to them. I was hoping that there would be some software that would allow me to enter the bitcoin addresses (not the private keys, as some are paper wallets) and "mass watch" the entered wallets, giving me a notification of any transaction that happened between the present and the last time I synced. Does any software like this exist?

Electrum allows that.

Electrum allows that.

If I remember correctly (and I hope I do because Electrum is my main wallet) I could add a watch address, but I'd have to open each address in a seperate window manually and I wouldn't get a notification if I did have a new transaction (it would show up in the history, but I'd have to manually check that and take note of the last transaction).

I'm really looking for a way to watch a large number of addresses (something like 10-30) and with 1 sync get be able to tell if any had a new transaction since the last time I synced it.

There is Watch only Bitcoin Wallet[1] which is an open source software that should allow you to watch multiple addresses at the same time , I don't think It sends any kind of notification though.
Another tool to really consider using is blockonomics.co[2] which is an online service that does the watches the address + notify you through your email address .

I think the "merchant" example script bundled with Electrum (the source) does exactly what you want. It monitors a number of wallet and notifies an application via the API when there are changes.

(However when I tried it I think some notifications got lost. Instead it was easier to iterate over all addresses and poll for changes. But that might have been user error. Try it yourself and ask for help in the Electrum part of the forum.)

Thanks guys, I'll have to check them out.

You will get more features using Electrum, such as being able to make a transaction (unsigned) and signing it with your cold storage,...
Also blockchain.info used to let you add watch only addresses, and sending you a free SMS message when you received/sent a transaction.

I would be glad to hear what you thought about my little project, and whether you wanted any specific feature that I could add as improvement.

Just flipping through the https://bitcoin.org/en/developer-reference#bitcoin-core-apis Remote Procedure Calls, remembering bitcoin-cli allowed simple requests about adresses or transfers send / recieved.

However the existance of some watchonly wallet on GitHub should have told me it isn't that easy.

Can someone confirm if running a bitcoin core client, empty wallet, can enable access to some blockchain explorer alike data? Just things like requesting current ballances associated with any given address (self owned or foreign) or last coin movements required.

Have you tried ImportAddress?

Have you tried ImportAddress?

I just downloaded it from GitHub on the other day (I thought it would be a lot bigger that it was, so I waited until I could get to public wifi). I have absolutely no idea how to compile the program from the source code, so (and I know this is probably just me not knowing anything about coding) I'm not sure if I just don't know how to compile the program or I didn't download the right thing. Nevertheless, if you could point me in the right direction that'd be nice.
