The BCH Admin code is open source so you can verify what the code is doing. The website itself is serverless (zero backend code) and only uses HTML, CSS &
clearly written, albeit a bit sloppy, client-side JavaScript: utilizing the
mainnet-js library/scripts to interact with the Bitcoin Cash blockchain and store the private keys within the Browser's IndexDB Storage. There is no malicious code that I am aware of within the index.html, or included JavaScript assets. Everyone is welcome to review the source code to confirm that.
BCH Admin uses an SSL certificate to encrypt communications on the website and mainnetjs essentially opens a websocket to a Bitcoin Cash node within your browser (whereas Electron Cash does this within the electron desktop application). You can also easily download the source code and host the wallet locally. The code still reaches out to third party nodes to verify tx data and broadcast transactions. The private keys used to sign transactions do not ever leave your browser's local storage and are not saved anywhere else.
* Please note that this software is offered AS IS with NO GAURANTEE that your funds will be safe. WE (https://KeepBitcoinFree.org) DOES NOT EVER HOLD YOUR PRIVATE KEYS; WE CANNOT, AND DO NOT WISH TO, STEAL YOUR Bitcoin Cash, BCH. This application is serverless, all keys are stored in your browser. Back up your seed phrase and derivation to restore your coins on any other Bitcoin Cash wallet.
