What I Learned About Solana Token Extensions

Short summary

A Web2 developer shares lessons from exploring Solana's Token-2022 Program, covering SPL token creation, metadata, on-chain transfer fees, and Soulbound tokens. The most interesting finding was Solana's ability to enforce token behavior at the protocol level rather than relying on backend code. The article is a personal learning summary without deep technical detail or code examples.

  • •Solana Token-2022 enables rules built directly into tokens at the protocol level
  • •Soulbound tokens can't be transferred, only burned — useful for certificates and identity
  • •Author plans to learn Anchor next for building complete Solana dApps
