NFT marketplaces mean platforms where you can create and store tokens, as well as perform various operations with them - in particular, buy and sell for cryptocurrency. It is important to note that settlements in ordinary money are not allowed. Transactions require a crypto wallet, which either any crypto trader already has, or is easily created from scratch. A reliable wallet can be created in the ecosystem for managing the GRIN4 cryptocurrency.
The purchase and sale transactions themselves are carried out in the format of auctions - the exposed lot is taken by the one who offers the highest price. However, it should be understood that putting NFT up for sale is not at all a guarantee that there will be any demand for it at all. Therefore, it will be quite useful for novice authors to take care of the promotion of their works in advance.
All NFT marketplaces have a similar principle of operation, but nevertheless are classified according to a number of characteristics. And the first of them is the audience. For example, Axie Infinity and CryptoKitties are popular platforms among gamers, sports fans buy video clips from matches at the NBA, and Foundation, Sotheby's and Christie's are in demand from artists and collectors. However, there are also universal marketplaces where you can buy almost anything - from digital paintings by famous artists to gifs with dragons. Examples of such platforms are OpenSea, LooksRare and Raible.
Next is the so-called "gas fee", that is, reimbursement of the cost of energy needed to produce cryptocurrency. The gas fee is not fixed, it depends on the blockchain and the type of operation. For example, for the purchase of NFT, it is minimal, since this is an insignificant process in terms of the required energy. But the creation of the NFT itself is an energy-consuming matter, so the fee will be much higher. You also need to remember about the commissions of the marketplaces themselves for transactions that are also individual.
And now let's talk about marketplaces, which are often in the top of various thematic ratings:
1. OpenSea is a universal platform on the Ethereum and Solana blockchains. At the moment, it is the largest among all existing marketplaces - it accounts for more than 80% of all transactions with NFT. The fixed commission for transactions is 2.5% from the seller.
2. Raible is another large and well-proven universal marketplace running on the blockchains Ethereum, Flow, Solana, Tezos, Polygon. The commission on it is divided equally between the seller and the buyer - 1% from each.
3. Magic Eden is a cult place for gamers and authors of works based on computer games. It works on the Solana blockchain, the commission from the seller is 2%.
4. SuperRare is a specialized art marketplace for artists and collectors specializing in exclusive works, which is reflected in its very name (super rare - "very rare"). Well, the commission on the resource is also appropriate - 15% of the NFT price from the seller and 3% from the buyer.
Thus, the choice of NFT marketplaces is really impressive, but it is best for novice sellers and buyers to try their hand at universal sites. And only then switch to thematic and, if desired and necessary, to exclusive ones, where real works of digital art are treated.
