Before reading this post, it’s suggested you read Part One focused on the OpenSea.io NFT Marketplace
Mintable.com – The Basics
Select “Mint an Item” from the main menu on the page header. Mintable allows you to share your existing NFTs already minted from another NFT marketplace, or mint a new item. Note: not all NFTs already minted are compatible. For example, OpenSea minted items are not compatible. Select “Create a new item”.
Before proceeding to mint a new item, there are relatively new minting options. “Gasless” or “Traditional Minting”. From what I understand, “Traditional Minting” requires a Gas (Fee) upon minting of the digital asset / NFT transaction, and the new “Gasless” option puts the Gas/Fee on the acquisition/purchase of the digital asset.
Another option before the minting process is “Which Blockchain do you want to mint on?” , and the choices are “Ethereum Mainnet”, the traditional blockchain , or “Immutable X”.
Immutable X uses a validity-based proof. Validity-based proof means that your assets can never be traded without your permission, which is the same security measure as the Ethereum mainchain, and your items can never be taken from you either. Nov 5, 2021

Select the classic options, Ethereum Mainnet, and Traditional [Mint], then “Proceed to Mint”.
Create and List an item for sale
Another difference between minting an NFT on Mintable.com and OpenSea.io is that when minting on OpenSea, the collector/user is allowed to mint an item without selling the digital asset. On Mintable.com, you mint and post the item for sale at the same time. On OpenSea, the user can mint new NFTs to collections of digital assets without needing to sell them.
The first step in the Mintable.com “Mint an Item”, or “Create and List an item for sale”, is to categorize and subcategorize the digital asset. The user is required to add this metadata about their digital asset. You can see why this would be a benefit, such as searching the marketplace for particular items to purchase. On the negative side, users minting assets are cornered into slots to categorize their work..
“What kind of item are you making?”
- Art
- Music
- Videos
- Collectibles
- Sports
- Utility
“Select Sub-category” has lots and lots of choices for each kind of digital asset.
“Mint in the Mintable Store” option to place your Digital Assets in the “generic” store verse a user defined store. A user defined store, similar to a collection from the OpenSea perspective, allows you to place your digital assets in a collection/store and popularize your assets based on the store front. Its a selling tool as well as a method to collect your works.
Once you select the Store option, a Token Address and Token ID is generated automatically for the digital asset / NFT.
“Token name” – This is the name of the NFT on the blockchain that will be displayed everywhere.
“Listing Title” – This is the name of the listing on Mintable. Can be the same as the Token name.
“Listing Subtitle” – This is the listing subtitle
“Listing Tags” – Use a comma, tab, or enter to separate your tags. Tags help your item become more searchable.
“Add Files” – Images, Videos, and GIFs. The digital assets being declared as unique, and ownership by the person creating the NFT.
“Other Metadata” – Add extra data on your token (maximum of 20 data allowed). Key / Value pairs of metadata for the Digital Asset.
“Item description” – allows the user minting the digital asset to provide a long description for this NFT.
“Transfer Copyright when purchased?” Yes/No Checkbox
“Allow buyer to resell?” Yes/No Checkbox
“Price and Type” – Fixed, Auction, Auction with Buy Now
“Fixed price – in USD or ETH“
Auction “Starting Bid Price“
“Auction Length” – from 12 hours up to 7 days
“List this Item” button
Comparison Summary
The Sniff Test
Mintable.com has an interesting feature that “scans” the user’s digital asset attributes using some type of object recognition then scans the internet to see if, in fact, the proposed digital asset is unique. So far that feature is exclusive to Mintable.com . This process takes place when the user goes to mint the proposed NFT.
Collections and Stores
OpenSea.io provides their marketplace users the ability to create Collections to group their NFTs as they see fit, and as of this writing, that is a free feature. Mintable.com provides their NFT Marketplace sellers the ability put up a storefront, which a user may use to sell similarly designed NFTs. There appears to be a significant cost to using one’s own store, or a user may use the generic Mintable.com store.
Interoperability / Portability
Both platforms, OpenSea.io and Mintable.com have the ability to add metadata to the NFT being minted using key/value pairs allowing for compatibility cross platforms, I.e. other NFT marketplaces or multiplayer online gaming, for example. As standards for cross platform NFTs develop, these key/value pairs may contain JavaScript or HTML.
