NFTs are Non-Fungible Tokens like ERC-721 (a smart contract standard) tokens, which are hosted on Ethereum’s own blockchain. NFTs are unique digital assets such as collectables, artworks or gaming items. As an artist, by tokenizing your work, you can brand it as your own to make it unique. The actual ownership is blockchain-managed.

Minting is the process of tokenizing your work and creating an NFT.

Yes, you can. And you can choose to sell it later.

Absolutely! There are zero transaction costs applicable for any price changes. Just remember to sign the request via your wallet.

You can. Just visit the details page of the collectable you own, open the ‘...’ menu and select ‘Transfer token’.

The ERC-721 standard allows the creation of NFTs and includes a possibility to terminate them - i.e., burning the token.

Whenever you create a collectable, you can set a certain percentage as royalty for secondary sales.
For example: You create a digital painting and sell it for 0.2 ETH and set the royalty at 10 percent. A buyer then sells your painting at a higher price point of 0.5 ETH. Here, the royalty system kicks in; as the original content creator, you receive 10 percent of that sale, (0.05 ETH).
Note: Presently, royalties set on Yunometa are not applicable on yunometa.com. However, the team is working on a cross-platform royalties implementation.

Yes, visit the details page of the token you want to report, click on the ‘...’ button and select ‘Report’.

Verified badges are granted to creators and collectors who show proof of authenticity and actively contribute to the marketplace. We consider multiple factors such as active social media presence and number of followers, engagements with community members, the number of minted and sold items, etc.

The only way to get verified is to fill out this form.
Here are some tips:
  • Submit a completed profile on Yunometa including a user picture, cover and a custom link. Provide at least two active social media profiles. These profiles should showcase examples of sharing artwork and participating within the community. A large organic follower base is a plus.
  • Document the creation process with behind the scenes/work in progress content. As a creator, share the backstory of your work. If you’re a collector, we will consider your purchase history.
  • We’d like to know your journey as a creator/collector. Tell us about yourself! Why are you on Yunometa? What are you selling/collecting? What is the concept of your art?

If it has been more than a week since you applied, it is likely that we received an incomplete profile or there is insufficient activity on your Yunometa account.
Complete profiles still require some time for validation as we receive numerous requests on a daily basis.
However, don't let that discourage you! A verified badge is not the key to success on the marketplace. Complete your profile, make more sales or purchases and try again later.

Polygon is a blockchain that provides scalable, secure and instant transactions with Ethereum currencies like ETH, USDC and DAI. Currencies must first be "bridged" from Ethereum's main net to Polygon. Think of Polygon as a sibling to Ethereum; the currencies are similar, but the two blockchains have slight differences.

The Yunometa team often requires a "transaction hash" from Etherscan or Polygonscan to troubleshoot support issues.
Transaction hashes are unique IDs that record each transaction on the blockchain. This includes NFT purchases, sales or even order cancelations. All gas fees paid will generate a transaction hash.

Floor price is the lowest price for collection items. Unlike the average item price, it is updated in real time. Dutch auctions are not included in floor price calculations.

Gas fees are like transaction fees on the Ethereum blockchain. When you make any transactions, such as transferring cryptocurrency to another wallet or purchasing an NFT on Yunometa, you'll need enough ETH in your wallet for the initial transaction and the associated gas fees.
The guide below explains the different fees chargedwhen you use the Ethereum blockchain on Yunometa. There are three types of gas fees:
  • One-time fees
  • Recurring fees
  • Actions that are gas-free

Users can use Polygon to create, buy and sell NFTs without paying any gas fees.

One-Time Fees
  1. Account Registration Fees

    If this is your first ever sale on Yunometa, you’ll need to pay an account initialization fee before you can list on Ethereum. This allows trading between your wallet and Yunometa and enables Yunometa to access the transfer items in the event of a sale.

  2. Token or Contract Approval (WETH, USDC, etc.)

    If the item you are listing was not minted on Yunometa but via a custom NFT contract, you will need to pay a one-time approval fee authorizing transactions. If this is your first time listing an auction, you will also need to approve WETH for trading.

You will need to repeat this approval every time you use a cryptocurrency for the first time.This includes other currencies like USDC and DAI.

Recurring Fees
You will pay gas fees on Ethereum when you execute the following:
  • Accept an offer
  • Transfer (or gift) an NFT to someone
  • Purchase an NFT
  • Cancel a listed NFT
  • Cancel a bid
  • Convert WETH back to ETH and vice versa
  • Freeze your metadata
  • Bridge ETH or withdraw ETH to and from Polygon
Gas-free actions
  • Mint a new NFT aka “Lazy Minting”
  • Create a collection
  • List an NFT as a fixed price
  • List an NFT as an auction
  • Reduce the price of an NFT you've listed* (WETH is only needed when you accept or create an offer)
as prices fluctuate due to network congestion; therefore, it's important to check websites like ETH Gas Station before confirming a transaction. If the gas prices are high, one possible solution is to try the transaction again later when prices are lower.

Polygon is a blockchain that provides scalable, secure and instant transactions with Ethereum currencies like ETH, USDC and DAI. In order to spend your Ethereum currencies on Polygon, you must first "bridge" them across to the Polygon blockchain.
This guide explains how you can transfer currencies from the Ethereum network to the Polygon (PoS) network.

WETH (Wrapped ETH) is a currency that allows users to make pre-authorized bids that can be fulfilled at a later date without any further action from the bidder. WETH is used to buy and sell with auctions on Yunometa. ETH and WETH are worth exactly the same amount and can be exchanged directly on your Yunometa profile.
