Clicking Sign In does nothing, running Chrome here.

Make sure your having Javascript turned on in your browser.
Cause in the Chrome browser at my end its working flawlessly.

Javascript is turned on, no errors in the console

EDIT: In privacy mode is does work so I'm guessing one of my Chrome add-ons is messing up your site and it looks like LastPass is causing it.

The sign-in pops up for me just fine, using Chrome.

What extensions do you have?  Ad-Block or anything?  It's got to be an extension that is blocking the javascript.

Here's a nodejs script I use to check my balance.  Could be useful for those that are concerned about the having wallet info online.  Install nodejs (nodejs.org) and run:

Code:

$ node walletmon.js

The script (just substitute your wallet's address...these are just a few random ones):

Code:

var http = require('http');
var currency = 'USD';
var addresses = [
    '17xxoEVft19Rg2V4vqop92Az7Hp7vbtttV',
    '13kEG7RopYCSqgG1T1YsULpTQx5sW1PLTy',
    '1MWYjCaMunK2rERswXxiNTV641y23k38BS',
    '1GaLzoNQbuJB4hDgY4YBgvjxzPqHkCebgj',
];

function getReceived(address, callback) {
    getData(address, 'received', callback);
}

function getSent(address, callback) {
    getData(address, 'sent', callback);
}

function getData(address, method, callback) {
    var options = {
      host: 'blockexplorer.com',
      port: 80,
      path: '/q/get'+method+'byaddress/'+address,
    };
    http.get(options, function(res) {
        var answer = '';
        res.on('data', function (chunk) {
            answer += chunk;
        });
        res.on('end', function (chunk) {
            if(chunk) answer += chunk;
            callback(answer);
        });
    });
}

function getWeightedPrices(callback) {
    var options = {
      host: 'bitcoincharts.com',
      port: 80,
      path: '/t/weighted_prices.json',
    };

    http.get(options, function(res) {
    var answer = '';
            res.on('data', function (chunk) {
            answer += chunk;
        });
        res.on('end', function (chunk) {
            if(chunk) answer += chunk;
            callback(JSON.parse(answer));
        });
    });
}

function fetch(index, callback) {
    getReceived(addresses[index], function(received) {
        var bal = Math.round(received * 1e8);
        getSent(addresses[index], function(sent) {
            bal -= Math.round(sent * 1e8);
            console.log(addresses[index]+' received: '+received+', sent: '+sent+', bal: '+(bal/1e8));
            callback(bal);
        });
    });
}

function main() {
    var total=0;
    var count=addresses.length;
    for(i=0; i<addresses.length; i++) {
        (function(index) {
            fetch(index, function(bal) {
                total += bal;
                count--;
                if(count == 0) {
                    getWeightedPrices(function(prices) {
                        var p24h = Math.round(total * prices[currency]['24h'] / 1e6) / 1e2;
                        var p7d = Math.round(total * prices[currency]['7d'] / 1e6) / 1e2;
                        var p30d = Math.round(total * prices[currency]['30d'] / 1e6) /1e2;
                        console.log('');
                        console.log('Total: '+ (total / 1e8) + ' BTC ('+addresses.length+' addresses)');
                        console.log('USD: '+p24h+'(24h), '+p7d+'(7d) '+p30d+'(30d)');
                    })
                }
            });
        })(i);
    }
}

main();

One feature I'd like to see is the ability to be notified by email if your balance changes.

[reubgr]

It would be nice to be able to add optional labels for accounts.

[Grouver (BtcBalance)]

stuff

Wallet info is online anyway. Thats the point.

Nice one, added to the feature list.

This one is already planned in.
Working on it.

[Grouver (BtcBalance)]

UPDATE v1.0 -> v1.1

Added

• Total balance viewer
• Address labeling

Fixed

• Some minor grammar mistakes

I hope you guys like it.

[willphase]

Interesting tool.

You should consider using the http://blockexplorer.com/q/mytransactions api instead of querying each address individually - this will reduce the load on blockexplorer.  With the limited number of addresses you support you should be able to query the balance in one HTTP request - I am doing 50 addresses at a time using this API with my Android wallet balance app (see my signature) - which is doing I believe the same thing as yours but running on an android phone rather than someone else's server.

Also - how are you expecting people to export their hidden change/pool addresses?  I had to write a tool for my users to do this until the mainline client gets the import/export key patch hopefully coming in 0.4

Thanks for your reply.

I am actually using this command to get the last received ammount.
But to actually get the send and received amounts of an address using this command you need to add two addresses to check what transactions happend between those two given, right?
So currently I am using the: getsendbyaddress and the: getrecceivedbyaddress command and I simply subtract them of each other to get the current balance of an address.
At the first I was trying to dig into the technique wich blockexplorer uses, since I don't like to be dependent of there speed and uptime.
They use a patch on there Bitcoin client to parse info about addreses out of the network.
To bad it didn't work out for me to get this patch working correctly.
I also asked theymos if it was okay to use there API for stuff like this.
Luckly he kindly agreed.

Not sure what your trying to say with your last sentence.

okay cool - you can parse all the info required using just the mytransactions API - you need to cache the transactions you get back from the GET request then do two passes (in memory, only one GET required)- the first pass you go through all the out blocks and look for payments to any of your addresses while storing the transactions, for each in block you see you remember the prev_out since you need to know how much was paid from the previous out transaction (otherwise you end up with inconsistent values due to transaction fees). The second pass you just loop through all your prev_outs you've previously cached, and find the out transactions that you cached on your first pass through of the in parts - and subtract these from the balance...  You can check how I did it for my app here if you find reading code easier than my rather wordy explanation

Because the mytransactions API allows you to ask for transactions related to multiple bitcoin addresses (separate with a dot) it's the most efficient way I found of doing it, especially for large keyrings (e.g. 1000+ public keys).

My last comment was referring to the fact that 'change' transactions (e.g. I have 2 BTC, I send you 1 BTC, so it's 1 BTC to your address, and 1 BTC to a new hidden address that bitcoin client generates) go to addresses so I was wondering how you export these from the bitcoin client.

Will's reply

Thanks for your reply.
I will take your advise into record.
Gonna research this a bit if this is an option to replace the current system.

Currently..... we are already at 45 accounts, whooo!

[Grouver (BtcBalance)]

And we are at 55 accounts now.

Working on a total balance exchange converter.
Stay tuned.

[goodlord666]

cool site!

unfortunately with bitcoin sending amounts back to invisible addresses in your wallet it won't show the accurate sum of btc in my wallet. just tested it and of approx. 1btc total it showed only a total of 0.1btc even with all addresses entered (the ones known to me and listed in my client).

had to do some research on block explorer to find out about hidden addresses. it summed up nicely when I had entered those.

I wish the Bitcoin client would make all of your addresses visible to you, even the ones you havent (knowingly) used yet. there's work to do.

other than that your site seems to work nicely :)

[Grouver (BtcBalance)]

Got my first donation.
Thank you very much to the person who donated!

[Grouver (BtcBalance)]

UPDATE v1.1 -> v1.2

Added

• Total balance viewer converted into USD (based on Tradehill)

Fixed

• Some IE bugs

I hope you guys like it.

Rather than checking blockexplorer for your wallet data, have you considered running your own block data software? There's an open source version in development on this thread: http://forum.bitcoin.org/index.php?topic=22785.0.

yup I would certainly like to do this if I can find an efficient/inexpensive/free way of hosting this- if only that I could use google cloud notifications to send messages to android phones about when someone pays money into their wallet so my wallet viewer could update automatically - hate having to poll

Will

[Grouver (BtcBalance)]

Added a print screen of the interface to the start post.

Working on the following things right now:

• Label help (not alot of labels seem changed yet, maybe cause people don't know yet you can click your label to change it)
• Nickname register option
• Euro display of total balance

[Grouver (BtcBalance)]

UPDATE v1.2 -> v1.3

Added

• Total balance viewer converted into EUR (based on Tradehill)
• You can now use a additional nicnkame in order to login
• First address has an standard label wich notifies the user about the fact the label can be adjusted

Let me know if you guys still like it.

Yes of course.
I tried this, but for some reason I could not get it to work.
So for now I decided to go via the easy way.
Right now its okay to parse the information via blockexplorer.
If this thing grows big, I of course need to get this to work without parsing from the blockexplorer API.

Maybe add caching of the blockexplorer data every 30 minutes?
At least until you can setup your own.
