# Token-2022 support

[Token-2022](https://spl.solana.com/token-2022) is Solana's extended token standard, [enabling features like transfer fees, metadata, and programmable restrictions](https://spl.solana.com/token-2022/extensions). Raydium's CLMM and CPMM pools support Token-2022 assets.

## Using Token-2022 on Raydium

Token-2022 is treated as an advanced feature:

* Enter the mint address manually to find the token (no search by name/ticker)
* Token logos and names may not display unless manually added
* You'll be prompted to acknowledge risks before interacting
* Once confirmed, swaps can route through Token-2022 pools

Users who haven't confirmed a Token-2022 token will only route through standard SPL pools.

## Transfer fee extension

Some Token-2022 tokens have a **transfer fee** — a percentage taken on every transfer, set by the token creator.

| What to know    | Details                                                     |
| --------------- | ----------------------------------------------------------- |
| When it applies | Swaps, adding/removing liquidity, any token transfer        |
| Who controls it | The token creator (not Raydium)                             |
| Is it fixed?    | No — issuers can change the fee at any time without warning |

Raydium displays transfer fees in the UI when possible, but cannot guarantee accuracy if the issuer updates them.

## Unsupported extensions

The following Token-2022 extensions **cannot** be used to create permissionless CLMM pools:

| Extension                  | Why it's blocked                                                   |
| -------------------------- | ------------------------------------------------------------------ |
| **Permanent delegate**     | Allows unlimited burn/transfer authority over any holder's tokens  |
| **Non-transferable**       | "Soulbound" tokens that can't be moved — incompatible with trading |
| **Default account state**  | Forces all new token accounts to be frozen by default              |
| **Confidential transfers** | ZK-encrypted balances are incompatible with AMM price discovery    |
| **Transfer hook**          | Custom transfer logic could interfere with pool operations         |

## Integration guidance

* test the exact extension set your token uses in a full wallet flow
* treat issuer-controlled transfer fees as mutable risk
* verify routing, add liquidity, and remove liquidity separately
