Arc 6 Catch-Up: Designing Tokens That Enforce Rules

Arc 6 of 100 Days of Solana focused on designing tokens that enforce rules using Token-2022 on devnet. It explored interest-bearing tokens, multi-extension mints, and frozen accounts, allowing asset behavior composition without custom on-chain programs. Arc 7 transitioned these concepts into NFTs, stripping the model back to token primitives like supply, decimals, and provenance. This demonstrated that Solana NFTs are built from the same underlying token mechanics as programmable objects, simplifying the process for Web2 developers.
