As a Web2 developer, I always thought tokens were just digital assets you could send and receive. After exploring Solana’s Token-2022 Program, I realized tokens can have rules built directly into them.
Over the past few days, I learned how to:
- Create and mint my own SPL token
- Add metadata like a token name and symbol
- Configure transfer fees that are enforced on-chain
- Build Soulbound (non-transferable) tokens
The most interesting part was Soulbound tokens. Once minted, they can’t be transferred—only burned. That makes them perfect for things like certificates, membership badges, identity verification, and achievement tokens.
One thing that really stood out was how Solana lets you enforce token behavior at the protocol level instead of relying on backend code. It completely changed how I think about token design.
There were definitely a few setup issues and confusing concepts along the way, especially understanding the difference between the original SPL Token Program and Token-2022, but building everything from scratch made those concepts much clearer.
Next, I’m looking forward to learning Anchor and building complete Solana dApps.
If you’re starting with Solana, I’d definitely recommend experimenting with Token Extensions—they’re a great way to understand what’s possible beyond basic token creation.
