After taking the art and gaming world by storm in million-dollar auctions, NFTs have now exploded into the mainstream with celebrities and big brands getting involved. Currently, the NFT market has over $40 billion valuation and more than $10 billion worth of NFTs are sold on a weekly basis. There are dozens of NFT marketplaces in existence, and many of them have a specific focus or niche. Here are the best apps to buy NFT.

1. Crypto.com and its wallet

Crypto.com is the number one NFT marketplace app as well as the best NFT wallet available. The app has grown to over 10 million users in recent years. While Crypto.com is mostly known due to the cryptocurrency exchange platform, the platform also hopped into the NFT bandwagon and launched the Crypto.com NFT marketplace in March 2021.

Crypto.com offers a well-designed platform and offers NFTs from categories such as music, crypto, gaming, sport, art, and much more. Even though the platform is developed on the Crypto.com blockchain, the company recently announced that it will be supporting Ethereum-based NFTs. This app doesn't charge any fees when someone purchases NFTs, which is a big plus for the users. When it comes to payments, users can fund their purchases through cryptocurrency or via credit/debit cards.

2. OpenSea and lots of sales

OpenSea is well known for NFT sales. The platform has all sorts of digital assets available and it is usually free to sign up and browse the extensive offerings. The app has an incredible asset range because the platform makes it simple to buy, sell, and mint NFTs, even for complete beginners. It also supports creators and artists and has an easy-to-use process for those that want to create their own NFTs.

This marketplace usually supports more than 150 different payment tokens, as best suits its name. You can connect the OpenSea app to your web-based account and view NFTs that you have previously purchased, and you can even create an NFT "wishlist" to keep tabs on intriguing assets.

3. Sketchar and drawing tools

Sketchar is the NFT app for anyone who finds NFT art too simple. Sketcher has its own NFT marketplace where you can buy and sell NFTs, which includes the apps on Martians 888 NFTs. The app enables you to create your own art, mint it as an NFT, and sell it on the app's marketplace. This app uses augmented reality training. If you want to create your own art, the app has a drawing tool and digital canvas to use. You can use it to learn how to draw by tracing lines. It's a method many traditional artists use to enlarge their art from doodles to sketches. The app developer will take about 5 percent of your first sale and 1 percent of all resales.

4. Axie Marketplace

The Axie Marketplace is based on Ethereum and Ronnin blockchains. The app facilitates the buying and selling of in-game tokenized characters known as Axies.  It has an innovative style of allowing gamers to be partial owners of the gaming platform, and this has given the app a remarkable acceptance as a market hub for Axie infinity. Markets on the Axie Marketplace usually trade exclusively with Axie characters, and to date, have accounted for more than 2.64 billion in Axie sales.

5. Enjin and Enjin Coin

Enjin is one of the first wallets designed for use with NFTs. While some apps were added to support NFTs after they became popular, Enjin was specifically designed with digital collectibles in mind. While apps like Trust only support Ethereum and Cardano, Enjin supports multiple blockchains.

The platform also has Enjin Coin and a cryptocurrency swap built into the app. You can therefore easily import over cryptocurrency wallets if you already have a wallet in a different place. Even though the wallet may not look modern at times, it's a very solid wallet for holding NFTs and other cryptocurrencies. If you are new to NFTs, when you sign up for Enjin you will get a free collectible deposit right into your wallet.

6. Token.art to show off

Token.art is one of the best apps for showing off NFTs. Once you have some NFTs, it is definitely important to show them off. With token.art, you can put your digital collectibles on display. To get started, you can import a wallet from a Cardano, Ethereum, or WAX address. You can then view your NFTs in card format. It becomes easy to swipe through your displays and easily show them to others who are interested in having a look at them.

7. Mintable on Ethereum and Ziliqa

Mintable is backed by Marc Benioff – owned Time Ventures and billionaire investor Mark Cuban. And it is considered one of the best apps to buy NFT. This app is a two-sided marketplace for buying and selling NFTs and usually resembles eBay. The platform is built on Ethereum and Ziliqa blockchains, and the site is integrated with MetaMask, where buyers can set up crypto wallets. Creators have the option to mint free "gasless" NFTs, short-run printable series, or traditional transaction-based items. Once you have fully set up your profile and loaded your wallet, buyers can purchase listed items or bid on auctions, with winners notified via email addresses.

8. Binance and only a 1 percent fee

Binance is widely perceived to be one of the best crypto exchange platforms in the globe, due to its colossal asset selection and massive daily trading volume. Just like Crypto.com, Binance entered the NFT market in 2021 by launching the Binance NFT Marketplace. The app offers a way for users to buy and sell NFTs without any problems.

The Binance NFT Marketplace can easily be accessed using one's standard Binance login credentials. Essentially, this means that there is no need to create a separate account.
