Icebox is a simple client side client that can view public cryptocoin wallet information and compare the holdings with several open exchange APIs. It shows a current snapshot of your cryptocoins and tokens against a quote currency.
Multiple wallets addresses are supported.
Visit https://whardier.github.io/icebox/ to get started. You will be presented an initial form that will generate a URL that you can use, or share, as you wish.
Take the following example:
https://whardier.github.io/icebox/?KiddoCollegeFund=ETH:0x29BBE4a7960fef776C9f1a8a2055Aa551D91a1B9Ð:0xc0FfEEFF79F9C1F2579F0E071b96768c75695fe9
The first query argument is a Key/Value pair where the key is your personal name for a specific address (KiddoCollegeFund) and the value is the address itself (ETH:0x29BBE4a7960fef776C9f1a8a2055Aa551D91a1B9).
You can also simply list a bare address (ETH:0x29BBE4a7960fef776C9f1a8a2055Aa551D91a1B9).
Last but not least you can list an optional url fragment which will bring focus to a specific wallet address as well as add it to the avialable wallet list if it isn't already specified (#0x29BBE4a7960fef776C9f1a8a2055Aa551D91a1B9).
Only public keys are in use.
This program only looks at publically available information and will never ask you for a private key.
