Third-party marketplaces often request a "hash list", more appropriately called a "mint list", of NFTs in order to create a collection for listing. This is due to the fact that there is currently no on-chain Collection standard on Mainnet Beta (Coming soon!). The "hash list" is a list of the mint accounts of all the NFTs in your collection and allows the marketplace to determine which NFTs belong in your collection and which do not.
The typical method to create the mint list is to a use a tool that finds all NFTs with a specific creator in the first position of the creators array. If your NFTs were minted with a candy machine this will be the candy machine creator id by default. If you have multiple candy machines that are part of the collection, you can create a separate mint list for each candy machine and combine them together to create a single mint list which you provide to the marketplace(s) you are listing with.
Candy Machine v2 has a separate
candy_machine_id found in your cache file which identifies the candy machine on-chain, and a
candy_machine_creator_id that it uses to sign the NFT by placing it as a verified creator in the creators array.
If you minted through the storefront or modified your NFTs to accommodate Phantom's collection ordering requirements, you might instead need to search by your creator wallet, if it is in the first position of the creators array.
Metaplex recommends only using tools that check for a verified creator, otherwise fake NFTs could end up on your list. The tools below are the ones we know of currently that check for a verified creator. If you have a tool that supports this, contact us and we'll add it to the list.
The following third-party tools can be used to generate the mint list:
- Sol-NFT Tools A web-based tool that allows you to generate a mint list and has other useful features as well. Easiest to use for non-developers.
Usage: put in your creator or candy machine creator id into the "Get Mint IDs" tab.
- Magic Eden Hash List Finder A web-based tool that allows you to generate a mint list.
