I spent two weeks building with Solana's Token-2022 program. I created fungible tokens, attached transfer fees, stacked interest on top, built
soulbound credentials, and minted NFTs with on-chain metadata. Every one of those features worked — eventually. But before "eventually," each one had a moment where my output was wrong, my transaction failed, or my wallet balance moved in a direction I didn't expect.
This post is about those moments. Not the happy path. The five mistakes
that cost me the most time, and exactly what I had to understand to fix
them.
