Keep in mind Foundation Money from the above listing of beforehand failed stablecoins? A number of days after the Terra collapse, information broke that Kwon was one of many two nameless founders of Foundation Money. Not solely ought to Kwon have seen it coming, however he had completed it earlier than.

So, Kwon and his main traders weren’t oblivious to the dangers of algorithmic stablecoins — they had been simply cocky sufficient to suppose they might outrun them. The plan was for Terra to turn out to be so massive and interwoven with the remainder of the financial system that it was actually too massive to fail.

This was formidable however not essentially insane. The free-floating fiat currencies of the world (just like the U.S. greenback) keep their worth as a result of they’re tethered to a big, functioning financial system the place that cash is beneficial.

As soon as you might be prepared, use the “Injected Web3” setting and deploy the sensible contract:

After your occasion of the above sensible contract is deployed, you’ll have the ability to copy its deal with into the “GameManager” script (35:45).

Minting NFTs

If you happen to keep in mind our demo, that to purchase NFTs in-game, gamers mint them by clicking on the “purchase” button. In addition they want to substantiate the minting transaction with their Web3 wallets. So, how will we set this up inside Unity? We use the “ShopItem” script (36:45).
The latter triggers the corresponding occasion, dealt with by the “PurchaseItemManager” script. The precise occasion handler (“ActivateItemPanel”) is triggered when gamers choose any explicit merchandise from the store.

One listener for detecting when a new offer is placed (selling) and another one to detect when an offer is closed (buying):

Furthermore, Moralis also provides you with a complete database containing live details regarding your users, which is available within your Moralis dashboard. These include token balances, transaction history, pending transactions, NFTs, and much more. This is also where the data regarding our listeners (underlined with green lines) is available:

Now that we’ve got the on-chain data at our disposal, we only need code snippets to use that data correctly.

There are two main aspects to the code required to create an NFT marketplace.

NFT dApp ideas are driving the adoption of blockchain across all demographics. So, if you’re looking for inspiration for your own NFT app ideas, you’re in the right place!

In this article, we’re going to show you three NFT app ideas that you can create quickly and easily. Furthermore, we’ll explore some of the next-generation tools that you can use to turn your NFT app ideas into exciting games and NFT marketplaces!

Also, if you want to learn the basics of coding, or if you just want to brush up on your JavaScript skills to get the most out of your NFT app ideas, check out the JavaScript Programming for Blockchain Developers course at Moralis Academy!

NFT App Ideas – How to Create NFTs

So, for our first NFT app idea, we will show you how to mint NFTs using Moralis.

GameFi represents a paradigm shift whereby players take ownership (or at least part ownership) of their favorite game(s).

GameFi in the Metaverse

What GameFi does is blend games and finance. Furthermore, it merges fun entertainment and games with the financialization of in-game economies. Blockchain technology enables players to show verifiable ownership of their assets and allows marketplaces for trading in-game items.

On the blockchain, tokens represent game objects.
The players can own their weapons, armor, and plots of land in blockchain-based games. So, in these games, players become participants and owners. Games may differ, but the recurring theme is striving to accumulate resources.
Playing well allows gamers to earn more in-game assets, fungible tokens, and NFTs.

Works only with networks that have already been added to Injected Wallet. You can find a guide on how to programmatically add a new network here. Easily customizable, you can add other networks

Options:

  • props (optional): networks to display.
    Added by default: polygon, eth, bsc and avalanche

<Chainspolygonethbscavalanche/

<CoinPrice /

💵 <CoinPrice / : displays the price of the token specified in the settings. Uses Moralis Web3API (does not require an active web3 provider).

Options:

  • address (required): Token contract address
  • chain (optional): The network to which the token is deployed.

Launch an NFT Marketplace with Moralis

To launch an NFT marketplace with Moralis, we need to keep certain backend functionalities in mind. As implied in the demo, these components are:

  1. A user authentication functionality that allows you to sign in to the dApp. For most dApps, the simplest way is to authenticate with MetaMask.
  2. Real-time tracking of user balances.
  3. The ability to track smart contract events as they occur in the dApp.

Remember that smart contracts form the logic of the NFT marketplace and are foundational to its design.

Smart contracts are the operational backbone of the marketplace. Moreover, the NFT marketplace dApp needs to interact with numerous other contracts to manage the NFTs, depending on their origin.

Implementing the above backend functionalities using RPC nodes, as mentioned, is meticulous and time-consuming.

In conventional finance, the time period for that’s “Ponzi scheme.”

Terra’s actual innovation on the standard Ponzi was splitting its targets into two symbiotic teams: a conservative group that wished to reduce draw back (UST) and an aggressive group that wished to maximise upside (LUNA). Pairing Ponzi-like economics with a stablecoin let Terra market itself to a a lot wider vary of traders, permitting it to develop a lot bigger than earlier crypto Ponzis.

The notorious Bitconnect Ponzi reached round $2.4 billion earlier than imploding. PlusToken and OneCoin grew to about $3 billion and $4 billion, respectively, earlier than their collapse. The Terra ecosystem peaked with LUNA at a $40 billion market cap and UST at $18 billion. By comparability, Bernie Madoff’s decades-long Ponzi “solely” price traders someplace between $12 billion and $20 billion.

populate

Balances()

Finally, we have the last function that triggers once the users authenticate, which is ”populateBalance()”. This function simply queries the balances of the users’ wallets and then displays the information in the dApp. As such, this is what the function looks like:

async function populateBalance(){ const presentBalance = await getBalance(ethereum.selectedAddress); const formatedBalance = “Your Market Place Balance is ” + Moralis.Units.FromWei(presentBalance) + ” ETH” document.getElementById(“balance”).innerHTML = formatedBalance; }

Selecting NFTs

We use the previous functions to populate data and display it to the users once they authenticate with MetaMask.

However, we also need some functions for performing the actions of the website.

By clicking on that, you can see the various functions and execute them, but we will interact with this smart contract directly through our Next.js app.

Make sure you keep note of the contract address, as we need it in the frontend to interact with the contract. We also need to keep note of the contract ABI, which indicates details of the various functions available in the smart contract.

To get the ABI, go to the Compile tab, and you should see this in the lower part:

Click on the ABI button to copy the ABI. Keep a note of it as we will need it later as well.

Creating a Moralis server

Now we need to set up a Moralis server. Head over to the Moralis website and create a new account if you don’t already have one. In the dashboard, click on Create a new server at the top.
