Arkham Intelligence has developed an app that uses a Twitter handle to search for anyone's activity across various blockchains, including Ethereum, Polygon, and BNB Chain.
The app can:
find wallet addresses that the user has interacted with;
filter the user's recent transactions;
visualize their actions on the blockchain.
Anyone who wants to join this impressive initiative can sign up for the waitlist.
The first entities on the waitlist are probably the IRS and the FRS.
