Online Bitcoin wallets often have one or two annoying idiosyncrasies, like demanding mandatory 2-FA, and there's nothing you can do about it. It's also not clear what information they collect. Besides, sometimes you just need a simple wallet. So I made The Simplest Bitcoin Wallet https://simcoin.info/tsbw/https://tsbw.ioMostly for myself, but maybe somebody will find it useful too. Main discussion is here. Please help test it, if you have a spare minute. If you like it, send some love here: 19BryCNdGs5F48J6yvw41pVSd5RDiA4j1x. ---- The code is based on coinb.in: I removed 3/4 of it, fixed a few bugs and rewrote the rest. It is now easier to read and verify. It's also a good start if you are interested to learn about Bitcoin and JS wallets since it's a lot simpler than the original. Usage example: var tx = btc.new_tx();
tx.add_input ('01020304abcdef', 0, '76a9141d8f0476ea05d9459e004fd0ff10588dd3979e6788ac'); // txid, no, script tx.add_output('13nwZVh9RsKuZGegVn5KWHM51dA98Mho5f', 1234); // address, amount
var keys = btc.get_keys('123'); // 123 = passphrase
var signed = tx.sign(keys);
console.log(signed);
Nothing is sent to my server, everything is done in the browser. It gets utxo and sends signed txs via external API's. All API access is wrapped in a "backend" object, which can be easily swapped. I wrote two: for blochchain.info and blockexplorer.com. You can enter a compressed or uncompressed WIF key as your passphrase; this means you can use the same wallets you have at https://coinb.in or any other wallet that allows exporting in this format.

Bitcoin mining is now a specialized and very risky industry, just like gold mining. Amateur miners are unlikely to make much money, and may even lose money. Bitcoin is much more than just mining, though!

Your "Simple Project" as sir here refers it to.

If the logical addressing is not taking part on the server side.Don't you think your wallet is prone to many attacks? I'm talking about simple injection of Java Scripts which simply run smoothly in any browser ? Where are the paraphrases stored anyway ?On the browser or as a session cookie ?

Your passphrase is not stored anywhere, it's your key, so make it strong. The address is generated directly from your passphrase (after some key stretching with two different hash functions). The security model here is no different than the coinb.in. A trusted browser should not allow javascript injection, especially into HTTPS connections. Not sure about browser extensions... It's probably best to use the wallet in the incognito mode and don't allow extensions to work there.

This is the simplest and easy to use wallet.
BTW There is one line on the site that states :
You can download it from github and use it locally.
There is no use of running it locally as there can't be any bitcoin transactions without internet !

If you run it locally, you can: a) check the source code only once and then avoid the risk that I inject something into it, b) make sure it's still available, even if my site goes down, c) use a different API for your transactions or modify anything else.

This is perfect solution for non-smartphone users since most online wallets are too complex so they can't work with mobile browser like Opera Mini. But, when I test it with "Responsive design view" in Firefox, the Send button don't appear in small resolution. Sorry for bad English EDIT: Correction, I wrong, the Send button appears. Anyway, good job!

If you can tweak CSS in index.html to make it appear I will happily merge your edits. If not - I've added it to my to-do list, so hopefully it will be fixed one day EDIT: Glad to hear it works now.

While "blockchain.info" really tries to "sell" the "2-FA" feature, it is not mandatory. I never use "2-FA" myself. What if my cell phone is stolen and I can't recover my account?! Better safe than sorry!

Ever tried logging in from a different geographical location? Or even a different browser? If you have an email set in your profile, you will be asked to authenticate using a link. And as far as I know, once you set that email, you can only replace it with a different one, never remove it. Anyway, I was talking in general about other services, not blockchain.info in particular.

Added Bitcoin Cash version: http://simcoin.info/tsbw/bcc/(You can use private keys as passphrase too). Please test with small amounts first, I just implemented it. Report any issues on github or here. Also, if anyone knows who runs blockdozer.com, please either tell them to add HTTPS or send me their contact info.

For BCC version the fee is set to 0.0001, it should be enough with bigger blocks.
Let me know if you experience any delays (or you can edit the fee yourself in index.html and run it locally).

And 2FA is just a way to ensure the safety of your money.

And simple code tends to be more secure and reliable.

So basically what you're looking for people to do, is to allow your website to create their private and public key pair. That information could easily be stored by you, in fact depending on the use of the wallet it would almost be expected. So with pretty much no business background that the public sees, you are expecting them to trust you with access to every single wallet that your site creates?

Why would you expect that? No, it is not easy to store it as the client sends zero information to my site. The whole point of deriving keys and signing the tx in JS is so the keys never leave your browser. If you are extra paranoid, you can run it from your local machine. The wallet is open-source and much simpler than coinb.in, you can verify everything even if you are not an expert.

I've see a lot of sites been shut down because of like these

Too expensive if using bitcoin for small transactions.
