Counterparty Graph

Sweeps Transfer logs twice — once with the address as sender, once as recipient, because topic filters are positional and cannot express "either" — then groups by counterparty. Classifies each as send-only, receive-only or two-way, which is usually more revealing than raw volume. Flags when one address dominates, since that is normally an exchange or router rather than a single counterparty, and notes that native transfers emit no logs at all. Only ERC-20 Transfer events are counted. Native coin transfers emit no log at all, so a wallet that mainly moves the chain’s own currency will look far quieter here than it really is. One address dominating the count is usually an exchange or router rather than a single counterparty.
