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/Mostly 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: 13nwZVh9RsKuZGegVn5KWHM51dA98Mho5f. ---- 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 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. What do you think about 2FA? It's silly to think that it's a nuisance. First of all, the web wallet supports you, it will help you facilitate the execution of the transaction, you can do it anywhere. 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. |

Both BTC and BCC versions now support uncompressed private keys (those that start with 5).

The Simplest Bitcoin Wallet got its own domain: https://tsbw.ioAlso I'm using Let's Encrypt for the first time, so let me know if there are any issues with HTTPS connection. |

Fees are now displayed in the wallet (if not, clear browser's cache and refresh the page). For BTC the fee is set to 0.0009 and it might still not be enough  |

safety and security is the first thing comes in my mind simple codes for a wallet is more phrone to attackers... system should be in critical algorithms and special codes server for them to run perfect and not to cause any malfunction any problems can result in youir wallet to report and close down.. I've see a lot of sites been shut down because of like these |

The wallet is really simple to use. But can we trust the wallet? I will try with a little amount because I like it simple.

For BTC the fee is set to 0.0009 and it might still not be enough It seems that 0.0009 btc is still a small fee in btc, however, with the current bitcoin value, we are paying a high fee for each transaction. Too expensive if using bitcoin for small transactions. |
