I have been working on a side project for the past couple of months. Mainly, my goal was to have a platform where I can login to all my crypto exchanges but not have to go through the login / 2FA steps and have a unified interface. I also didn't want to upload my API keys to a 3rd party server like it's the case with coinigy.

That's how I came up with Silex, the API keys are stored encrypted on your laptop and you only need a PIN code. The PIN code is just guaranteeing that someone who steals your laptop cannot access your funds before you have time to realize it and cancel your API keys.

How does the encryption work? The PIN code is sent to my server and is hashed with salt, the hash is checked against a hash stored in my database. If the hash is wrong a pin retry count is decreased. After 5 wrong pin, the account is cancelled. Their is no PIN reset available. If successful, the hash is sent back to the client and is used as encryption key for the local storage of account information. So the attacker would have to attack my database and steal / hack my laptop to gain access to my fund. This sounds safe enough for me, but I'm open to suggestions.

Not all exchanges are created equal and at this stage of development, not all exchanges allow all operations. That being said, in its current version, 7 different exchanges have been integrated: Binance, GDAX, Bittrex, Kraken, Kucoin, Poloniex, Cryptopia. Let me know who should be next.

Now you can give a try, just go to http://silexapp.com and click download.
