Wallet age in days, first & last activity timestamps, and outgoing transaction count for any Base address — read straight from the Base archive, not a 30-day feed, so it dates wallets of any age. Counts and last-activity cover what the wallet SENT; inbound transfers don't raise the nonce and aren't counted. Built for sybil screening and counterparty trust checks.
