Publish a deep dive on token extensions to DEV

Over the past several days you have moved from minting basic SPL tokens into the deeper waters of token extensions. You have layered on transfer fees, metadata, default frozen accounts, non-transferable flags, and permanent delegates. You have read configuration accounts to understand what others have built. You have thought carefully about which combinations make sense for which use cases. Today you are going to slow down, look back at what you have learned, and turn it into a public artifact. You will publish a technical post on DEV that explains token extensions to a developer who is in the same place you were a week ago. This is a Document day. The win is the published URL.

The Challenge

What you’ll need

• A DEV account (free, sign up with GitHub if you do not already have one)
• Your notes, screenshots, and code snippets from the previous token extensions days
• A text editor for drafting (your IDE works, or write directly in the dev.to editor)
• Access to the official Token Extensions documentation for fact-checking

Steps

1. Open the DEV new post editor at https://dev.to/new. If you are not signed in, you will be prompted to log in or create a free account first.

2. Choose your angle. A good Document post does not try to cover everything. Pick one of these focuses, or invent your own:

   • “What Token Extensions are and why a Web2 developer should care”
   • “Three token extension combinations I tried this week, and what each is good for”
   • “Reading a token mint: how I learned to inspect on-chain configuration”
   • “Soulbound credentials on Solana: combining non-transferable and permanent delegate”

3. Write a strong title and a one-sentence subtitle. The dev.to editor exposes both. Titles that mention a concrete outcome (“I built a compliance-gated token in 40 lines”) consistently outperform vague titles (“My Solana journey, week 6”).

4. Draft the post with this skeleton, adapted to your angle:

   • A short hook that frames the problem in Web2 terms (a gift card that expires, a license that can be revoked, a stock that has compliance gates)
   • A plain-English explanation of the relevant extension or extensions
   • One code snippet you actually ran this week, with comments explaining what each piece does
   • What surprised you, what confused you, and what clicked
   • A closing paragraph pointing readers to the official Token-2022 extensions guide if they want to go deeper

5. Add at least one code block. Use triple backticks with a language hint so the dev.to renderer applies syntax highlighting. Rust and TypeScript both work. Example:

   // Your snippet here
   

6. Tag the post. In the DEV editor sidebar, add the tags solana, web3, learning, and 100daysofsolana. Tags are how readers in the DEV community discover your work.

7. Add a cover image if you have one (a screenshot of your terminal output works). Posts with cover images get noticeably more clicks on the DEV feed.

8. Read the post out loud once before publishing. Reading aloud catches sentences that sound clean on the page but trip a real reader. Fix anything that makes you pause.

9. Click Publish. Copy the URL of the published post.
