Bars inside a result compare the listings on this page only. “Last called” is that listing's own observation date — the sweep is rolling, so these dates differ between rows. An em dash means the archive holds no such fact; it is never rendered as zero.

observed USDC

No listing on this page declares a wallet with observed inbound USDC.
