The problem Path to Vitalik solves

There are many cases, where finding wallets connections might be applied:

• HR: find what your potential employee is doing on blockchain, and who they interact with
• Compliance check: see if the address is associated with some funky activity (recent case: Tornado Cash)
• Do your own investigation: we will get you the tools

Challenges I ran into

Within this limited timeframe, one have to cut corners. Thus, the code is not as stable and elegant as we would like it to be.
The contract and backend are relatively straightforward. Creating a frontend was most challenging thing for us.
