Why?
Because we already have more than 2000 labels in our open-source ton-labels collection. And 8M custodial wallets for CEX, apps and even some trading bots.
These tables are available on Dune:
dune.ton_foundation.dataset_labels
dune.ton_foundation.result_custodial_wallets
That means we know the source or the destination of 70%+ jetton transfers. No other chain is transparent like this.
