TokenForensics

Bubblemaps is the most impactful on-chain tool I have encountered. It is neither a block explorer nor a charting tool, but a 'visual investigation engine' that can directly convert token distribution, wallet interactions, and hidden relationships into bubble charts, making on-chain financial relationships impossible to hide.
For me, it's not just fun, but also useful. From the distribution of MEME coin pump addresses, the wash trading behavior of NFTs, to the concentration of funds in liquidity pools, Bubblemaps allows for a quick grasp of the structure. Especially their Intel Desk feature, which combines community analysis, on-chain search, and transaction visualization layers, is a magical tool for investigating on-chain projects or conducting investment research.
