How to Mint your Space

  • The first step is to upload your Space toโ€‹
  • Once you've uploaded your Space, (including your playground files and mintable files), be sure to select at least one theme for your space. Your Space will then enter our QA process.
  • As soon as your space passes QA, you will be notified, and the mint button on your Space Draft page will be enabled.
  • Click the mint button to begin the process.
  • *You will need either ETH or Matic in your wallet for the gas fees. See below for more on this.
  • Once you mint your space, you will see a link in your Space Drafts page to view your Space NFT on Opensea, where you can sell it to a collector!
    • Note: it may take 10-15 mins for your Space NFT to populate on OpenSea after minting
  • You will have a choice between minting on either Ethereum or Polygon
  • There are several things to consider when choosing between Ethereum and Polygon.
Here is a great article where you can learn more about the differences between each.


  • โ€‹Ethereum is where most NFTs (including high-end art and collectibles) are currently minted. Ethereum is more popular than Polygon, and NFTs minted on Ethereum are easier to sell and re-sell. With that popularity comes more network traffic and higher gas prices.
  • Ethereum has high gas fees. This means that in order to mint your space on Ethereum, you will be prompted to pay a fee in order to do so. Currently, we're seeing gas fees of around $200. Unfortunately, this is the norm for minting on Ethereum, for any platform right now. The gas fees fluctuate wildly throughout the day, so if you're seeing high fees now, you can check back an hour later or even in another few minutes and you might see them a bit lower (or higher).
  • While the gas fees are high, the financial upside for an artist minting on Ethereum is significantly higher than minting on Polygon.


  • โ€‹Polygon (previously known as Matic) is a proof-of-stake chain, which is built on top of Ethereum. While not as popular as Ethereum, Polygon has gained a lot of traction in the community. NFT artists seeking a cheaper, more environmentally friendly solution have been turning to Polygon to mint their work.
  • Polygon has significatly lower gas fees when compared to minting directly on Ethereum. Fees are typically less than $1.
  • โ€‹Follow this guide to add the Matic network to your MetaMask Wallet.

If you are planning to mint on Polygon and need to add Matic to your wallet, please reach out to the Mona Team in the Discord.


Please Note

  • While Polygon is cheaper and more accessible for those who are less familiar with crypto, keep in mind that saving money upfront on minting fees may end up costing you in the long-run. There is a chance that these initial Spaces become wildly popular with major collectors who typically pay high amounts to collect and trade NFTs minted on Ethereum.

What about other chains?

  • Currently, we only support minting on Ethereum and Polygon. We are working on supporting other chains, especially those that are carbon negative, such as Algorand. If you'd like to recommend a certain chain, please send us a message in our Discord.

How do I sell my Space?

  • Once you mint your space, it will automatically generate a listing for it on OpenSea. Here, you will be able to set a price or enable an auction, and sell your space to a collector.
  • It can take 10-15 mins after you mint for your Space to show up on OpenSea.
