# Token Extensions WNS offloads as much functionality to the Solana Token Extensions program as possible: * **Metadata** - Asset metadata leverages the Metadata Token Extension * **GroupPointer** - For collection data, point the collection Mint to a Group account to define a collection with the group pointer * **MemberPointer** - For individual NFTs, point the NFT Mint to a Member account to attach it to a collection with the member pointer * **Group\*** - The account that represents a collection of NFTs. * **Member\*** - The account that gives on-chain direction for what Group an NFT is apart of. * **ImmutableOwner** - Owners token accounts cannot be transfered to evade transfer hooks. * **TransferHook** - Each NFT has a Transfer Hook attached to it that validates the proper accounts were generated by the Marketplaces who paid royalties. \*Currently this is represented by a WNS account as the Solana Token Extensions program doesn't support these extensions on mainnet. Once these go live, there will be a migration for all outstanding collections. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
