What I Learned About Token Design on Solana as a Web2 Developer

Short summary

A Web2 developer shares lessons from building tokens on Solana's Token Extensions Program, where mint-level flags replace custom backend logic. Tokens can carry their own metadata, enforce transfer fees without middleware, and become non-transferable at the protocol level. The article walks through concrete CLI commands for each extension and combines them on a single mint.

• •Solana Token Extensions let mints carry metadata, transfer fees, and non-transferability as native flags
• •Transfer fees are withheld on recipient accounts and swept by authority—no payment processor needed
• •Non-transferable tokens are enforced by the program itself, not application code
