MetaSleuth is a crypto-tracking and investigation platform. It can help monitor market movements, track the flow of funds from criminal activities, and DYOR to avoid scams. MetaSleuth is built by blockchain security company BlockSec, and the platform is now in beta and is currently free to use. MetaSleuth leverages BlockSec's large and constantly evolving address labeling system, but users can customize their own labels and add notes to addresses and transactions. The platform is based on intelligent analysis (screening the most valuable connections by default), enables cross-chain analysis, and allows users to share, save, or download their own analysis.
