answers 402
Did this token's contract change under you? Compare a Base contract against Tereno's previous observation and catch a silent proxy upgrade, an admin swap, a bytecode change or a contract that just got paused: the moves that turn a token you can sell into one you cannot. Every answer names the block it stops being valid at, so a bot knows when to re-check. Priced for the moment a launch is screened
