# Singular: FAQ

## What is a verified collection?

A verified collection is one that has been hand-vetted by the RMRK team to be original and exclusive to RMRK. For a collection to be verified, please apply to [this form](https://forms.gle/B3j4HQbSZeJFx3ME8). Before doing so, make sure you have an identity set on your profile in [Your Space](https://singular.rmrk.app/space).

## How much are minting fees on Singular?

Around ~3 cents per mint.

## How do I get curated / featured on the home page?

The RMRK team currently democratically decides on curation. If we collectively agree by majority without veto that a collection should be curated (also known as featured), it will be chosen as such.

We base out criteria on the following parameters:

- is the collection verified? (see above)
- does the collection have a banner?
- does the artist have an identity set up in their space?
- has the artist actively participated in the RMRK protocol with purchases and/or sales?
- does the artist have a positive balance of [RMRK tokens](https://singular.rmrk.app/tokens) (at least 10 RMRK)?
- does the artist or the collection have a community existing or growing around it?

Furthermore, we judge the collections based on:

- Skill/Craftsmanship
- Originality
	- Interesting Medium
	- Interesting Project (Well thought-out concept, innovative, etc)
	- General Novelty

Note: if at any point a featured artist's RMRK balance goes below 10 RMRK, the collection will be removed from the Featured section.

## What does "Top" mean in "Top Artists" and "Top Collectors"?

These are the addresses who sold most NFTs or collected most NFTs (in KSM value) respectively.

## How do I mass-mint?

Contact us at contact@rmrk.app if you'd like to launch a big collection. We'll add mass-mint tools with RMRK 2 functionality on Singular, but until that happens, you should refrain from using third-party mass-minters due to the coming hosting fee (see next section).

## Where is NFT data stored?

We store everything on IPFS and pin it on Pinata and our own IPFS node. This is currently free. In the near future, we will add a minting fee that will depend on the file size being uploaded, bottoming out at $1 in KSM.

This means all mints will, in the future, cost around ~$1 at a minimum to recoup our hosting costs.

It will remain possible to mint via command-line, scripts, and third party tools, but due to the possibility of those pins disappearing, we will make it clear that such NFTs might be unsafe to consider permanent.

Any user - owner, issuer, or viewer - will be able to sponsor the supplement pinning fee for third-party minted NFTs, turning the NFT into a "pinned-by-RMRK" NFT.
