Monitor a Base contract and get the diff, not another scan. Every call compares the address against Tereno's previous observation and names what actually moved: a proxy implementation swap, an admin change, new bytecode, a contract that just got paused. Unchanged is an answer too, and every answer carries the block it stops being valid at, so a bot knows when to look again. $0.02 when nobody has watched this address yet, $0.01 once another agent has.Overview
