The Secure Lightweight Bitcoin Wallet in your Browser

Image from store SpareCoins
Description from store Why use SpareCoins? === **Convenience** === Using a Desktop Wallet sucks if you’re sending a small amount of Bitcoins. Opening them in another window feels clunky, and syncing with the Blockchain can take a day. SpareCoins is in your browser and can be opened with one click, or Ctrl+Shift+K. This makes sending Bitcoins around the web much easier. === **Security** === Every week, another online Bitcoin Wallet gets hacked. SpareCoins, however, does not have a central point for attackers to target. Your private keys are encrypted and stored inside your browser, rather than an unsafe remote server. Your private keys can be backed up at anytime, and clearing your cache won’t delete your keys. === **Open Source** === SpareCoins is an Open Source project and holds true to the philosophy of Bitcoin through decentralizing online wallets whilst maintaining convenience. The ultimate vision is to facilitate transactions that were previously impossible, such as the ANYONECANPAY and MULTISIG protocols. We welcome developers to fork the repo on Github. The app is built on top of AngularJS and Bitcoinjs-lib.

    In the top righthand corner on the APP, there is a SPANNER, clicking this will bring up 3 options. Select BACKUP WALLET and download. ... Go to DOWNLOAD FOLDER (You might want to move or rename the file, but anyway ...) Right click and select OPEN WITH Choose NOTEPAD .... VOILA .. it will show you 3 lines .. Encrypted Privated Keys (AES) Use a SHA256 digest of your password as the encryption key "the encryption code" I hope this FINALLY helps .. Regards, Stephen Sartain
  • (2021-08-21, v:1.0.13) alex: But does not allow you to get back to your login properly ...
    The main problems are it stopped allowing send and the coins are just sat there and using it on a different google chrome on a new laptop ( they tend to get broke or old) does not bring up your old account, as you only have a password to login to the extention you added to chrome.
