The original title is "5 Token-2022 Mistakes I Made So You Don't Have To"

Short summary

Solana Token-2022 developer shares five critical mistakes: decimal unit confusion in fee calculations, wrong extension initialization order, inability to add extensions post-creation, interest as display formula not ledger state, and off-chain metadata caching delays. Each includes practical Web2 analogies and fixes.

• •Always multiply fee caps by 10**decimals; base units ≠ whole tokens
• •Initialize extensions before createInitializeMintInstruction, or get cryptic errors
• •Design token schema at creation; extensions can't be added or removed later
