Any puzzle, any collection. Right here, in the page.
The page imports @agntn/puzzles and runs it in your browser. Balances go through the worker to the chain's explorer. Every state is a link you can send to someone.
Verified means a published key derives the stored address. It doesn't mean the address still holds anything. The balance line is what the explorer said, five minutes ago at most.
