Hello! I’ve been working on a project which attempts to trace confidential tokens. What this means practically is decrypting balances and transfer amounts.
Here’s the first iteration on github. Unfortunately since i’m a new user i can’t add links, but you can fill in the gaps 
github (.) com / ericDeCourcy / confidential-token-scanner
It needs a lot of polishing still, but i’m open to discussion and contributions. Right now, the form it takes is a script which allows you to input an address, and the script returns all confidential token transactions involving that address. After each transaction, the script shows a minimum and maximum balance for that address.
The github repo also contains databases of token transactions. These are visible on ethereum, but i save you the time of having to scrape them 
Anyone is free to do whatever they want with the data and to open pull requests on the github.
There’s a link to the writeup on medium if you go to the github “About” section.
