Token Extensions

Token Extensions add optional functionality to Token-2022 mints. Some extensions are supported on Orca, while others may require additional review or are not supported.

Token Extensions overview

Token Extensions are optional Token-2022 features that can change how a token behaves, including how transfers, metadata, account states, fees, or permissions work. Because some extensions can affect token transfers or pool interactions, not all Token Extensions are supported by Orca Whirlpools. Some supported extensions require a Token Badge before they can be used with Orca. Token Badges are reviewed by Orca on a case-by-case basis. A Token Badge is not an endorsement of a token, project, team, or community, and does not guarantee liquidity, trading activity, route availability, or third-party platform support. If your project uses Token Extensions and needs Token Badge review, contact Orca through the Support function in the wallet menu, or through Discord or Telegram. For a deeper technical overview of Token Extensions, see the Solana Foundation Token Extensions white paper.

Token Badge review

Some extensions require Token Badge review before they can be used with Orca Whirlpools. A Token Badge may be required where a token feature can affect transfers, account permissions, pool interactions, or other behavior that Orca needs to evaluate before supporting the token in Whirlpools. Token Badge review is handled case by case. Review timing and outcomes may vary based on the token configuration, extension behavior, and any follow-up information required. To request Token Badge review, contact Orca through one of these channels:
