Subtitle: Token-2022 showed me that tokens can have rules, not just balances. This week I moved past basic SPL tokens and started using Token Extensions. At first, I thought a token was mostly just: a mint token accounts balances transfers But Token-2022 adds something more interesting: behavior. A token can charge transfer fees. A token can display interest over time. A token can start every account frozen. A token can be non-transferable. A token can have a permanent delegate for revocation. T
