It's difficult and expensive to code and implements NFT smart contracts. However, you may now avoid all of that.
NFTs are a trendy issue right now, and so many developers are eager to incorporate them into their programs. However, if you want to permit your app's users to mint NFTs, you'll have to overcome a few challenges:
● Buying and holding cryptocurrency to cover gas costs is a hassle.
● Using private keys can lead to a slew of security vulnerabilities.
● Smart contract coding and deployment are extremely tough and costly.
Taking a closer glance at each of the following-
Implementing an ERC-721 smart contract may cost anywhere from $400 - $2,000 USD, depending on the prevailing gas cost on Ethereum. Imagine investing so much money just to discover that you made an error inside this smart contract and therefore must redeploy. For the vast majority of developers, such costs are simply unaffordable.
Of course, you can always develop NFTs on less expensive blockchains such as Binance Smart Chain (BSC), Celo, Harmony, or Polygon. Nonetheless, you must learn how to code smart contracts. As you'll soon discover, this is a demanding task that might take several weeks or months to master. Even if you utilize a tutorial and deploy a basic NFT smart contract, even the tiniest error can render your app unusable or endanger its security. Not to add that each blockchain has its own smart contract, therefore minting on many chains is nearly impossible.
So you'd like to pay for gas?
You'll also have to pay for gas in order to mint NFTs. If you're only printing a handful, this shouldn't be a problem. However, suppose you want to develop an app serving hundreds or even thousands of users across many blockchains. In that case, you'll need to buy crypto through exchanges and ensure you continuously have enough on each blockchain to cover their gas fees.
You'll now have to comply with cryptocurrency rules, and good luck if the bank objects to you accessing your account to purchase cryptocurrency. If they do, some banks will even put a hold on your account. To summarize, paying gas fees using crypto brings a host of possible concerns that could cause your NFT app to crash.
To compensate for the gas expenses, you must utilize private keys from inside the app to mint NFTs. However, if someone obtains your private keys, they will have immediate access to all of your assets. So, how does one go around doing this safely?
It is certainly doable, but it would be a major undertaking. Don't even think about allowing your users to generate NFTs through mobile apps. It's a whole new can of worms, plus one that will stymie your project until you have a comprehensive system in place. It could take months to create one on your own, and perhaps even then, you might encounter flaws.
To be honest, there is no way to avoid or reduce Ethereum's gas fees. And there's no way to make smart contract development any easier. But what if a person had the option of skipping all of that?
You can see now.
Few sites have developed NFT Express, new functionality that eliminates the need to deploy or code smart contracts. You can quickly and simply mint as many NFTs as any developer can desire on five blockchains.
The gas fees needed minting each NFT are basically taken from the monthly paid plan, as they have already developed and implemented smart contracts for you.
This eliminates the need to keep crypto or ensure that you have sufficient coins at a blockchain location to mint NFTs. And one won't even have to deal with private keys. So put those security concerns to the side and welcome NFT minting functionality in mobile apps!
The source code for smart contracts in the pre-deployed NFT is available on their site. They are standardized and audited. They're basically OpenZeppelin agreements with a few extra features. The blockchain experts of those particular sites have years of experience and have done the legwork for you by creating secure and interoperable smart contracts from which you may rapidly mint tokens.
Our contracts allow you to mint an unlimited number of tokens and are available on BSC, Ethereum, Celo, Polygon and Harmony. They're also quite simple to use.
To use NFT Express, you only need to make one API call. You only need to enter three parameters:
chain - The blockchain on which you're minting - The address of the receiver
Tatum provides the private key, the token ID is automatically generated, and the smart contract address is set towards the Tatum smart contract upon that blockchain you're using automatically. Gas fees are deducted automatically from your paid Tatum plan's monthly credit balance.
On each blockchain, you won't have to worry about dealing with private keys securely, paying for gas fees, or deploying smart contracts with crypto. NFT Express includes everything you'll need to quickly and easily mint NFTs.
If you're pretty excited about initiating the project and want to see how it works for yourself, sign up for an API key. Because your petrol expenses are deducted from your monthly credits, you will require to subscribe to a paid Tatum plan.
Which plan one should choose is determined by the blockchain(s) you intend to use. Initiate the process with Start Plan, which should have been enough to mint enough NFTs for blockchains with cheaper gas fees, like Celo and Harmony. Because Ethereum's gas fees are currently very high, contact a few sites, and they will probably work with you to create a unique Enterprise Plan that meets your demands.
