How to Check Which Token-2022 Extensions a Token Uses
Token-2022 extensions don't show up on any price chart — here's exactly where to look, and what a block explorer's raw data actually tells you.
Knowing that Token-2022 extensions exist is one thing — actually finding out which ones a specific token has enabled requires looking in the right place, since this information doesn't appear on a typical price chart or trading interface.
Why Standard Trading Interfaces Don't Show This
Most exchanges, price trackers, and trading interfaces display a token's price, volume, and chart — none of which reflect its underlying Token-2022 configuration. A token can look completely ordinary on every trading platform while having several extensions enabled that only become visible through a different kind of lookup entirely.
Using a Solana Block Explorer Directly
A Solana-specific block explorer like Solscan or Solana Explorer can display a token mint's account data directly, including whether it uses the standard Token Program or Token-2022, and — for Token-2022 tokens — the specific extensions configured on that mint account.
What the Raw Account Data Typically Looks Like
Token-2022 extension data is stored in a structured format within the mint account, which a block explorer may present as raw, technical data rather than a clean, labeled summary — readable with some familiarity with how the standard is structured, but not always immediately intuitive for someone checking a token for the first time.
Why a Dedicated Scanning Tool Can Simplify This
Because raw extension data isn't always presented in plain language by a general-purpose block explorer, a tool built specifically to parse and explain Token-2022 configurations can translate that same underlying data into a more direct answer — which extensions are enabled, and what each one actually permits for that specific token.
What to Specifically Look For Once You Can See the Extensions
Whether Transfer Fee is enabled, and if so, the configured rate and whether it can still be changed. Whether Permanent Delegate is set, and to which address. Whether Default Account State is set to frozen. Each of these carries meaningfully different implications, and a token can have any combination of them enabled simultaneously.
Why Checking This Should Happen Before Buying, Not After
Because these extensions affect fundamental things like whether tokens can be transferred at all, or whether a percentage is taken on every transfer, discovering this after already buying in means encountering the consequence directly rather than making an informed decision beforehand.
Building This Into a Regular Habit
For any new Solana token — particularly ones without an established, well-known history — checking the underlying token standard and its specific extension configuration is worth treating as a standard step, alongside the other checks that already apply to any new token regardless of chain.
Check a Solana token's Token-2022 extensions directly, translated into plain language, rather than relying on raw block explorer data or a project's own description of its token.
